Protection of the environment
General notes
Environmental note
H
Daimler's declared policy is one of comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
R
operating conditions of your vehicle
R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R
avoid short trips as these increase fuel consumption.
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
R
remove roof racks once you no longer need
them.
R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R
always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R
do not depress the accelerator pedal when
starting the engine.
R
do not warm up the engine when the vehicle
is stationary.
R
drive carefully and maintain a safe distance
from the vehicle in front.
R
avoid frequent, sudden acceleration and
braking.
R
change gear in good time and use each gear
only up to Ô of its maximum engine speed.
R
switch off the engine in stationary traffic.
R
keep an eye on the vehicle's fuel consumption.
Environmental concerns and recommendations
Wherever the operating instructions require
you to dispose of materials, first try to regenerate or re-use them. Observe the relevant
environmental rules and regulations when
disposing of materials. In this way you will
help to protect the environment.
Genuine Mercedes-Benz parts
Environmental note
H
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
Air bags and Emergency Tensioning Devi-
!
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R
doors
R
door pillars
R
door sills
R
seats
R
cockpit
R
instrument cluster
R
center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
Page 27
Introduction
25
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes.
This could lead to malfunctions in safety-relevant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tires, wheels and
accessories that have been specifically
approved for your vehicle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been specifically developed, manufactured or selected
for and adapted to Mercedes-Benz vehicles.
Only genuine Mercedes-Benz parts should
therefore be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.
All authorized Mercedes-Benz Centers maintain a supply of genuine Mercedes-Benz parts
for necessary service and repair work. In addition, strategically located parts delivery centers provide quick and reliable parts service.
Always specify the vehicle identification number (VIN) when ordering genuine MercedesBenz parts (Y page 446).

Sports Utility Vehicle
WARNING
G
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road
conditions. There is a risk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the
prevailing road and weather conditions.
Utility vehicles have a significantly higher rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle,
and severe or fatal injury.
In a rollover crash, an unbelted person is significantly more likely to die than a person
wearing a seat belt.
You and all vehicle occupants should always
wear your seat belts.
Operating safety
Important safety notes
WARNING
G
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/maintenance work as well as any required repairs
carried out at a qualified specialist workshop.
WARNING
G
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
WARNING
G
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk
of fire.
Z
Page 30
Introduction
28
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
WARNING
G
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other networked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as intended and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as electronic components or their software. You
should have all work to electrical and electronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle electronics, the general operating permit is rendered invalid.
There is a risk of damage to the vehicle if:
!
R
the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R
you drive too fast over an obstacle, e.g. a
curb or a hole in the road
R
a heavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body, the undercarriage, chassis parts, wheels or tires
could be damaged without the damage
being visible. Components damaged in this
way can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system, they can catch
fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on continuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
visit a qualified specialist workshop.

typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
R
how various systems in your vehicle are
operating
R
whether or not the driver and passenger
seat belts are fastened
R
how far (if at all) the driver is depressing the
accelerator and/or brake pedal and
R
how fast the vehicle is traveling
This data can help provide a better understanding of the circumstances in which
Page 33
Introduction
31
crashes and injuries occur. NOTE: EDR data is
recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by
the EDR under normal driving conditions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, can
combine the EDR data with the type of personal identification data routinely acquired
during a crash investigation.
Access to the vehicle and/or the EDR is needed to read data that is recorded by an EDR,
and special equipment is required. In addition
to the vehicle manufacturer, other parties
that have the special equipment, such as law
enforcement, can read the information by
accessing the vehicle or the EDR.
EDR data may be used in civil and criminal
matters as a tool in accident reconstruction,
accident claims, and vehicle safety. Since the
Crash Data Retrieval CDR tool that is used to
extract data from the EDR is commercially
available, Mercedes-Benz USA, LLC
("MBUSA") expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or,
if the vehicle is leased, without the consent of
the lessee. Exceptions to this representation
include responses to subpoenas by law
enforcement; by federal, state or local government; in connection with or arising out of
litigation involving MBUSA or its subsidiaries
and affiliates; or, as required by law.
Warning: The EDR is a component of the Supplemental Restraint System ("SRS") Module.
Tampering with, altering, modifying or removing the EDR component may result in a malfunction of the SRS Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of
February 2013, 13 states have enacted laws
relating to EDRs.

Occupant safety
Restraint system: introduction
The restraint system reduces the risk of occupants hitting parts of the vehicle interior in the
event of an accident. Furthermore, the
restraint system may also reduce the forces
exerted on the vehicle occupants when an
accident occurs.
The restraint system includes:
R
Seat belt system
R
Air bags
R
Child restraint system
R
Child seat securing system
The components of the restraint system work
in conjunction with each other. They can only
offer the intended level of protection if all
vehicle occupants:
R
are correctly wearing their seat belts.
(Y page 47)
R
adjust their seat and head restraint properly (Y page 105).
The driver is also responsible for ensuring
that the steering wheel has been correctly
positioned. Observe the information relating
to the correct driver's seat position
(Y page 104).
Always ensure the air bag can inflate properly
if deployed (Y page 50).
An air bag supplements a correctly fastened
seat belt and is an additional safety device
providing increased protection for vehicle
occupants in appropriate accident situations.
For example, if the protection already provided by a correctly fastened seat belt will suffice, the air bags are not deployed. Furthermore, only the air bags that would increase
the degree of protection afforded to the vehicle occupants in the event of an accident are
deployed. Seat belts and air bags generally do
not protect against objects penetrating the
vehicle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt tensioners and air bags" (Y page 58).
Page 47
Occupant safety

See “Children in the vehicle” for information
on children traveling with you as well as vehicle restraint systems (Y page 61).
Important safety notes
WARNING
G
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even
fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify an air bag system to
accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for
details. USA only: for further information contact our Customer Assistance Center at
1-800-FOR-MERCedes (1‑800‑367‑6372).
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the engine is running. Therefore, malfunctions can be detected in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the ignition is switched on. It goes out no later than a
few seconds after the engine is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R
does not light up after the ignition is
switched on
R
does not go out after a few seconds with
the engine running
R
lights up again while the engine is running
WARNING
G
If restraint system is malfunctioning, restraint
system components may be triggered unintentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emergency Tensioning Device or air bag, for example. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp :
is part of the Occupant Classification System
(OCS).
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the frontpassenger front air bag.
If the PASSENGER AIR BAG OFF indicator
lamp:
R
is lit: the front-passenger front air bag is
deactivated. They will then not be deployed
in the event of an accident.
R
does not light up: the front-passenger
front air bag is enabled. If, in the event of an
accident, all deployment criteria are met,
the front-passenger front air bag is
deployed.
Safety
Z
Page 48
Occupant safety
46
Depending on the person in the frontpassenger seat, the front-passenger front air
bag must either be disabled or enabled; see
the following points. You must make sure of
this both before and during a journey.
R
Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the
Safety
installed child restraint system, and the age
and size of the child. Therefore, be sure to
observe the notes on the "Occupant classification system (OCS)" (Y page 53) and
on "Children in the vehicle" (Y page 61).
There you will also find instructions on
backwards- and forwards-facing child
restraint systems on the front-passenger
seat.
R
All other persons: depending on the classification of the person in the frontpassenger seat, the front-passenger front
air bag is enabled or deactivated
(Y page 53). Be sure to observe the notes
on "Seat belts“ (Y page 46) and "Air bags"
(Y page 50). There you can also find information on the correct seat position.
Seat belts
Introduction
A correctly fastened seat belt is the most
effective means of restraining the movement
of vehicle occupants in the event of an accident or overturn. This reduces the risk of
vehicle occupants coming into contact with
parts of the vehicle interior or being thrown
from the vehicle. Furthermore, the seat belt
helps to keep the vehicle occupants in the
best position in relation to the air bag.
The seat belt system consists of:
R
Seat belts
R
Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear compartment
R
Belt force limiters
If the seat belt is pulled quickly or suddenly
from the belt sash guide, the inertia reel
locks. The belt strap cannot be pulled out further.
Emergency Tensioning Devices tighten the
seat belts in an accident, pulling them close
against the occupant's body. They do not,
however, pull vehicle occupants back
towards the backrest.
Emergency Tensioning Devices do not correct an incorrect seat position or incorrectly
worn seat belts.
When activated, the belt force limiters reduce
the force exerted by the seat belt on the vehicle occupants.
The belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This
makes it possible to reduce the forces to
which vehicle occupants are subjected during
an accident.
If the front-passenger seat is unoccupied,
!
do not insert the belt tongue into the buckle
of the front-passenger seat. This may otherwise lead to the triggering of the Emergency Tensioning Device in the event of an
accident, which will then need to be
replaced.
Important safety notes
The use of seat belts and child restraint systems is required by law in:
R
all 50 states
R
the U.S. territories
R
the District of Columbia
R
all Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
WARNING
G
If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an
incorrectly fastened seat belt can cause additional injury, for example, in an accident, dur-
Page 49
Occupant safety
47
ing braking or when abruptly changing direction. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seat
belt.
WARNING
G
The seat belt does not offer the intended level
of protection if you have not moved the backrest to an almost vertical position. When braking or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
WARNING
G
Persons under 5 ft (1.50 m) in height cannot
fasten the seat belt correctly without an additional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable restraint
systems.
(Y page 61) in addition to the child
restraint system manufacturer's installation instructions
R
be sure to observe the instructions and
safety notes on the "Occupant classification system (OCS)" (Y page 53)
WARNING
G
The seat belts may not perform their intended
protective function if:
R
they are damaged, modified, extremely
dirty, bleach or dyed
R
the seat belt buckle is damaged or
extremely dirty
R
the Emergency Tensioning Devices, belt
anchorages or inertia reels have been modified
Seat belts may be damaged in an accident,
although the damage may not be visible, e.g.
due to splinters of glass. Modified or damaged
seat belts may tear or fail, e.g. in an accident.
Modified Emergency Tensioning Devices
could accidentally trigger or fail to deploy
when necessary. This poses an increased risk
of injury or even fatal injury.
Never modify the seat belts, Emergency Tensioning Devices, belt anchorages or inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Following an accident, have the seat belts checked
immediately at a qualified specialist workshop.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
Safety
If a child younger than 12 years and under 5 ft
(1.50 m) in height is traveling in the vehicle:
R
always secure the child in a child restraint
system suitable for this Mercedes-Benz
vehicle. The child restraint system must be
appropriate to the age, weight and size of
the child
R
always observe the instructions and safety
notes in the "Children in the vehicle" section of this Operator's Manual
Proper use of the seat belts
Observe the safety notes on the seat belt
(Y page 46).
All vehicle occupants must be wearing the
seat belt correctly before beginning the journey. Also make sure that all vehicle occupants are always wearing the seat belt correctly while the vehicle is in motion.

When fastening the seat belt, always make
sure that:
R
the seat belt tongue is only inserted to the
belt buckle belonging to that seat.
R
the seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
Safety
R
the seat belt is not twisted.
Only then can the forces which occur be
distributed over the area of the belt.
R
the shoulder section of the belt is always
routed across the center of your shoulder.
The shoulder section of the belt must not
come into contact with your neck or be
routed under your arm. If possible, adjust
the seat belt to the appropriate height.
R
the lap belt passes tightly and as low down
as possible across your lap.
The lap belt must always be routed across
your hip joints and not across your abdomen. This applies particularly to pregnant
women. If necessary, push the lap belt
down to your hip joint and pull it tight using
the shoulder section of the belt.
R
the seat belt is not routed across sharp,
pointed or fragile objects.
If you have such items located on or in your
clothing, e.g. pens, keys or eyeglasses,
store these in a suitable place.
R
only one person is using a seat belt at a
time.
Infants and children must never travel sitting on the lap of a vehicle occupant. In the
event of an accident, they could be crushed
between the vehicle occupant and seat
belt.
R
objects are never secured with a seat belt if
the seat belt is also being used by one of the
vehicle's occupants.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe
the "Loading guidelines" for securing objects,

Seat belt adjustment
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. This
function adjusts the driver's and frontpassenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
R
the belt tongue is engaged in the buckle
and
R
the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off in the on-board computer
(Y page 280).
Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the instrument cluster is a reminder that all occupants
must fasten their seat belts. It may light up
continuously or flash. In addition, there may
be a warning tone.
Regardless of whether the driver's and frontpassenger seat belts have already been fastened, the 7 seat belt warning lamp lights
up for six seconds each time the engine is
started. If, after six seconds, the driver or
front-passenger seat belt has not been fastened and the doors are closed, the 7 seat
belt warning lamp lights up. As soon as the
driver's and front-passenger seat belts are
fastened or a front door is opened again, the
7 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. This warning tone stops after
Safety
Z
Page 52
Occupant safety
50
six seconds or when the driver's seat belt is
fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and frontpassenger seat belts are not fastened, a
warning tone sounds. A warning tone also
sounds with increasing intensity for
60 seconds or until the driver or front
Safety
passenger have fastened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again.
For more information on the 7 seat
i
belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat
belts" (Y page 318).
Air bags
Introduction
The installation point of an air bag can be recognized by the AIR BAG symbol.
An air bag complements the correctly fastened seat belt. It is no substitute for the seat
belt. The air bag provides additional protection in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function independently from one another (Y page 58).
However, no system available today can completely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
WARNING
G
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R
have fastened their seat belts correctly,
including pregnant women
R
are sitting correctly and maintain the greatest possible distance to the air bags
R
follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occupants.
R
Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
R
Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
R
Only hold the steering wheel on the outside. This allows the air bag to be fully
deployed.
R
Always lean against the backrest while driving. Do not lean forwards or lean against
the door or side window. You may otherwise be in the deployment area of the air
bags.
R
Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may otherwise be in the deployment area of the air
bag.
R
For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R
Always secure children under 12 years of
age and less than 5 ft (1.50 m) in height in
suitable child restraint systems.
R
Child restraint systems should be installed
on the rear seats.
Page 53
R
Only secure a child in a rearward-facing
child restraint system to the frontpassenger seat when the front-passenger
front air bag is disabled. If the PASSENGER
AIR BAG OFF indicator lamp is permanently
lit, the front-passenger front air bag is disabled (Y page 45).
R
Always observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (Y page 53) and on "Children
in the vehicle" (Y page 61) in addition to
the child restraint system manufacturer's
installation instructions.
Objects in the vehicle interior may prevent the air bag from functioning correctly. Before starting your journey and to
avoid risks resulting from the speed of the air
bag as it deploys, make sure that:
R
there are no people, animals or objects
between the vehicle occupants and an air
bag.
R
there are no objects between the seat, door
and B-pillar.
R
no hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
R
no accessories, such as cup holders, are
attached to the vehicle within the deployment area of an air bag, e.g. to doors, side
windows, rear side trim or side walls.
R
no heavy, sharp-edged or fragile objects
are in the pockets of your clothing. Store
such objects in a suitable place.
WARNING
G
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
WARNING
G
Sensors to control the air bags are located in
the doors. Modifications or work not performed correctly to the doors or door paneling, as well as damaged doors, can lead to the
Occupant safety
function of the sensors being impaired. The air
bags might therefore not function properly
any more. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door paneling carried out at a qualified specialist workshop.
Front air bags
Driver's air bag : inflates in front of the
steering wheel; front-passenger air bag ;
inflates in front of and above the glove box.
When deployed, the front air bags offer additional head and thorax protection on the front
seats.
The PASSENGER AIR BAG OFF indicator lamp
shows you the status of the front-passenger
front air bag (Y page 45).
Front-passenger air bag ; is only deployed
if:
R
the Occupant Classification System (OCS)
recognizes that the front-passenger seat is
occupied (Y page 53)
R
the PASSENGER AIR BAG OFF indicator

Driver's knee bag : deploys under the steering column. The driver's knee bag is triggered
together with the front air bag.
The driver's knee bag offers additional thigh,
knee and lower leg protection for the occupant in the driver's seat.
Side impact air bags
WARNING
G
Unsuitable seat covers could restrict or even
prevent the deployment of the air bags integrated into the seats. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. In addition, the function of the Occupant Classification System
(OCS) could be restricted. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bags : and rear side
impact air bags ; inflate next to the outer
cushions of the seat backrest.
When deployed, the side impact air bag offers
additional protection for the thorax. Furthermore, on the front seats additional protection
is offered for the pelvis. However, it does not
protect your:
R
head
R
neck
R
arms
In the event of a side impact, the side impact
air bag is deployed on the side on which an
impact occurs.
The side impact air bag on the frontpassenger side (front) deploys in the following situations:
R
the OCS system detects that the frontpassenger seat is occupied, or
R
the belt tongue is engaged in the buckle on
the front-passenger seat
If the belt tongue is engaged in the buckle on
the front-passenger seat, the side impact air
bag on the front-passenger side deploys at
the onset of the applicable accident situation.
In this case, it will deploy regardless of
whether the front-passenger seat is occupied
or not.
Window curtain air bags
Window curtain air bags : are integrated
into the side of the roof frame and deploy in
the area from the A-pillar to the C-pillar.
Page 55
Occupant safety
53
When deployed, the window curtain air bag
offers additional protection for the head.
However, it does not protect your chest or
arms.
In the event of a side impact, the window curtain air bag is deployed on the side on which
the impact occurs.
If the system determines that window curtain
air bag deployment can offer additional protection to that provided by the seat belt, a
window curtain air bag may deploy in other
accident situations (Y page 58).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the frontpassenger front air bag is either enabled or
deactivated.
The system does not deactivate:
R
the side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices
In the following situation, the side impact air
bag and Emergency Tensioning Device are
disabled: the OCS system detects that the
front-passenger seat is occupied, but the seat
belt tongue is not inserted in the belt buckle
of the front-passenger seat.
If the front passenger does not observe these
conditions, OCS may produce a false classification, e.g. because the front passenger:
R
transfers their weight by supporting themselves on a vehicle armrest
R
sits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. The entire base of the
child restraint system must always rest on the
seat cushion of the front-passenger seat. The
backrest of the forwards-facing child restraint
system must, as far as possible, be resting on
the backrest of the front-passenger seat.
The child restraint system must not touch the
roof or be put under strain by the head
restraint. Adjust the angle of the seat backrest and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instructions.
Occupant Classification System operation (OCS)
Safety
Prerequisites
To be classified correctly, the front passenger
must sit:
R
with the seat belt fastened correctly
R
in an almost upright position with their
back against the seat backrest
R
with their feet resting on the floor, if possible
PASSENGER AIR BAG OFF indicator lamp :

ton once or twice on vehicles with KEYLESS-GO.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then displays the status of the frontpassenger front air bag. If the status of the
Safety
front-passenger front air bag changes while
the vehicle is in motion, an air bag display
message may appear in the instrument cluster (Y page 295). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger
front air bag both before and during the journey.
If the PASSENGER AIR BAG OFF indicator
lamp:
R
is lit, the front-passenger front air bag is
deactivated. They will then not be deployed
in the event of an accident.
R
does not light up: the front-passenger
front air bag is enabled. If, in the event of an
accident, all deployment criteria are met,
the front-passenger front air bag is
deployed.
WARNING
G
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the frontpassenger seat could then, for example, come
into contact with the vehicle's interior, especially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R
the classification of the person in the frontpassenger seat is correct and the frontpassenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
R
the front-passenger seat has been moved
back as far back as possible.
R
the person is seated correctly.
Make sure, both before and during the journey, that the status of the front-passenger
front air bag is correct.
WARNING
G
If you secure a child in a child restraint system
on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of an accident. The child
could be struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
WARNING
G
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too
close to the dashboard, the child could, in the
event of an accident:
R
come into contact with the vehicle's interior if the PASSENGER AIR BAG OFF indicator lamp is lit, for example
R
be struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even
fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder
belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and downwards from the vehicle belt sash guide. If necessary, adjust the vehicle belt sash guide and
the front-passenger seat accordingly. Always
observe the child restraint system manufacturer's installation instructions.

Occupant safety
55
If OCS determines that:
R
the front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the frontpassenger front air bag is deactivated.
R
the front-passenger seat is occupied by a
child of up to 12 months old, in a standard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indicates that the front-passenger front air bag
is deactivated.
But in the case of a 12-month-old child, in a
standard child restraint system, the
PASSENGER AIR BAG OFF indicator lamp
can go out after the system self-test. This
indicates that the front-passenger front air
bag is activated. The result of the classification is dependent on, among other factors, the child restraint system and the
child's stature. It is recommended that you
install the restraint system on a suitable
rear seat.
R
the front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager
or small adult), the PASSENGER AIR BAG
OFF indicator lamp lights up and remains lit
after the system self-test depending on the
result of the classification or, alternatively,
goes out.
-
if the PASSENGER AIR BAG OFF indicator
lamp is off, move the front-passenger
seat as far back as possible. Alternatively, a person of small stature can sit on
a rear seat.
-
if the PASSENGER AIR BAG OFF indicator
lamp is lit, a person of smaller stature
should not use the front-passenger seat.
R
the front-passenger seat is occupied by an
adult or a person of a stature corresponding to that of an adult, the PASSENGER AIR
BAG OFF indicator lamp goes out after the
system self-test. This indicates that the
front-passenger front air bag is activated.
If children are traveling in the vehicle, be sure
to observe the notes on "Children in the vehicle" (Y page 61).
When OCS is malfunctioning, the red 6
restraint system warning lamp in the instrument cluster and the PASSENGER AIR BAG
OFF indicator lamp light up simultaneously.
The front-passenger front air bag is deactivated in this case and does not deploy during an
accident. Have the system checked by qualified technicians as soon as possible. Consult
an authorized Mercedes-Benz Center. The
front-passenger seat should only be repaired
at an authorized Mercedes-Benz Center.
If the front-passenger seat, the seat cover or
the seat cushion is damaged, have the necessary repair work carried out at an authorized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recommends that you only use seat accessories
that have been approved by Mercedes-Benz.
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy. The Occupant Classification
System (OCS) categorizes the occupant in the
front-passenger seat. Depending on that
result, the front-passenger front air bag is
either enabled or deactivated.
System self-test
DANGER
G
If the PASSENGER AIR BAG OFF indicator
lamp does not light up during the system selftest, then the system is malfunctioning. The
front-passenger front air bag might be triggered unintentionally or might not be triggered at all in the event of an accident with
high deceleration. This poses an increased
risk of injury or even fatal injury.
In this case the front-passenger seat may not
be used. Do not install a child restraint system
on the front-passenger seat. Have the Occupant Classification System (OCS) checked
and repaired immediately at a qualified specialist workshop.

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes
WARNING
G
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Safety
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified specialist workshop as soon as possible.
WARNING
G
A deployed air bag no longer offers any protection and cannot provide the intended protection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified specialist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of any
passengers to have deployed air bags
replaced and to have any malfunctioning air
bags repaired. This will help to make sure the
air bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.
WARNING
G
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer operational and are unable to perform their intended protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Tensioning Devices which have been triggered
immediately replaced at a qualified specialist
workshop.
An electric motor is used by PRE-SAFE®to
trigger the tightening of the seat belt in hazardous situations. This procedure is reversible.
If the Emergency Tensioning Devices or air
bags are deployed, you will hear a bang and a
small amount of powder may also be
released. The 6 restraint system warning
lamp will light up.
Only in rare cases will the bang affect your
hearing. The powder released is generally not
hazardous to health, it could however cause
short-term breathing difficulties in people
with asthma or other respiratory problems. In
order to prevent breathing difficulties, you
should leave the vehicle as soon as it is safe to
do so, or open the window.
Air bags and pyrotechnic seat belt tensioners
contain perchlorate material, which may
require special handling or environmental
protection measures. Check with your local
government’s disposal guidelines. California
residents, see www.dtsc.ca.gov/
HazardousWaste/Perchlorate/
index.cfm.
Method of operation
During the first stage of a collision, the
restraint system control unit evaluates important physical data relating to vehicle deceleration or acceleration, such as:
R
Duration
R
Direction
R
Intensity
Based on the evaluation of this data, the
restraint system control unit triggers the belt
tensioners in the event of a frontal or rear
collision.
An Emergency Tensioning Device can only be
triggered if:
R
the ignition is switched on
R
the restraint system components are ready
for operation, see “Restraint system warning lamp” (Y page 45)
R
the belt tongue is inserted into the buckle
on the respective front seat
The belt tensioners in the rear compartment
are triggered independently of the lock status
of the seat belts.
Page 61
Occupant safety
59
If the restraint system control unit detects a
high accident severity, additional components of the restraint system are activated
independently of one another in certain frontal collision situations:
R
Front air bags and driver's knee bag
R
Windowbag, if the system determines that
it can offer additional protection to that
provided by the seat belt
Depending on the person occupying the frontpassenger seat, the front-passenger air bag is
activated or deactivated. The front-passenger
front air bag can only be deployed in an accident if the PASSENGER AIR BAG OFF indicator lamp is off. Observe the information on the
PASSENGER AIR BAG OFF indicator lamp
(Y page 45).
Your vehicle has two-stage front air bags.
During the first deployment stage, the front
air bag fills with propellant gas which reduces
the risk of injury. The second stage is then
triggered within milliseconds, filling the front
air bag with the maximum amount of propellant gas.
The deployment thresholds for the Emergency Tensioning Devices and air bags are
calculated on the basis of the vehicle deceleration or acceleration occurring at various
points in the vehicle. This process is pre-emptive in nature. The air bag must be deployed
on time, at the start of the collision.
The rate of vehicle deceleration or acceleration and the direction of the force are essentially determined by:
R
distribution of the force during the impact
R
collision angle
R
deformation characteristics of the vehicle
R
characteristics of the object with which the
vehicle has collided
Factors which can only be seen and measured
after the collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indication of air bag
deployment.
The vehicle may be considerably deformed
without an air bag being deployed. This is the
case if only relatively easily deformable parts
have been hit and a high rate of deceleration
has not been reached. Conversely, an air bag
may be deployed even though the vehicle suffers only minor deformation. This is the case
if, for example, very rigid vehicle parts such as
the longitudinal body members are hit in an
accident and the rate of deceleration is sufficient.
If the restraint system control unit detects a
side impact or an overturn situation, the relevant restraint system components are activated independently of one another depending on the apparent type of accident. If additional protection for the vehicle occupants is
determined in this situation, the belt tensioners are also triggered.
R
Side impact air bags on the side of the collision, regardless of Emergency Tensioning
Device and use of the seat belt on the driver's side and the outer seats on the second

the OCS system detects that the frontpassenger seat is occupied or
-
the belt tongue has engaged in the belt
buckle of the front-passenger seat.

PRE-SAFE®(anticipatory occupant
protection system)
Introduction
In certain hazardous situations, PRE-SAFE
takes pre-emptive measures to protect the
vehicle occupants.
Important safety notes
Make sure that there are no objects in the
!
footwell or behind the seats. There is a danger that the seats and/or objects could be
damaged when PRE-SAFE®is activated.
Although your vehicle is equipped with PRESAFE®, the possibility of injury in the event of
an accident cannot be ruled out. Always
adapt your driving style to suit the prevailing
road and weather conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
Function
PRE-SAFE®takes the following measures
depending on the hazardous situation detected:
R
the front seat belts are pre-tensioned.
R
if the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains. The panorama roof with
power tilt/sliding panel is completely
closed.
R
vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavorable position.
R
vehicles with a multicontour seat: the air
pressure in the side bolsters of the seat
®
backrest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE®slackens
the belt pre-tensioning. On vehicles with multicontour seats, the air pressure in the side
bolsters is reduced again. All settings made
by PRE-SAFE®can then be reversed.
If the seat belt pre-tensioning is not reduced:
X
Move the seat backrest or seat back
slightly when the vehicle is stationary.
The seat belt pre-tensioning is reduced and
the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. Information about the convenience function can
be found under "Belt adjustment"
(Y page 49).
PRE-SAFE®intervenes:
R
in emergency braking situations, e.g. when
BAS is activated
R
in critical driving situations, e.g. when physical limits are exceeded and the vehicle
understeers or oversteers severely
R
on vehicles with the Active Driving Assistance package: if BAS PLUS intervenes
powerfully or the radar sensor system
detects an imminent danger of collision in
certain situations
Automatic measures after an accident
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
R
by activating the hazard warning lamps
R
the emergency lighting is activated
R
the vehicle doors are unlocked
R
the front side windows are lowered

Children in the vehicle
Important safety notes
Accident statistics show that children
secured in the rear seats are safer than children secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better protected there.
If a child younger than 12 years and under 5 ft
(1.50 m) in height is traveling in the vehicle:
R
always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles. The child restraint system must be
appropriate to the age, weight and size of
the child
R
be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
R
be sure to observe the instructions and
safety notes on the "Occupant classification system (OCS)" (Y page 53)
WARNING
G
If you leave children unsupervised in the vehicle, they could set it in motion by, for example:
R
release the parking brake.
R
shift the automatic transmission out of the
parking position P.
R
start the engine.
In addition, they may operate vehicle equipment and become trapped. There is a risk of
an accident and injury.
Children in the vehicle
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
WARNING
G
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
WARNING
G
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Children may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Protect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting properly. Particular attention must be
paid to children.
Observe the safety notes on the seat belt
(Y page 46) and the notes on correct use of
seat belts (Y page 47).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
41 lbs (18 kg) or until they reach a height
where a lap/shoulder belt fits properly without a booster seat.
Special seat belt retractor
WARNING
G
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retractor is disabled and the inertia real draws in a

rest must be folded back as far as possible.
You can obtain further information about the
correct child restraint system from any
authorized Mercedes-Benz Center.
WARNING
G
If the child restraint system is installed incorrectly on a suitable seat, it cannot protect as
intended. The child cannot then be restrained
in the event of an accident, heavy braking or
sudden changes of direction. There is an
increased risk of injury, possibly even fatal.
Make sure that you observe the child restraint
system manufacturer's installation instructions and the notes on use. Please ensure,
that the base of the child restraint system is
always resting completely on the seat cushion. Never place objects, e.g. cushions, under
or behind the child restraint system. Only use
child restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers.
WARNING
G
If the child restraint system is installed incorrectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, striking vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always install child restraint systems properly, even if they are not being used. Make
sure that you observe the child restraint system manufacturer's installation instructions.

You will find further information on stowing
objects, luggage or loads under "Loading
guidelines" (Y page 334).
WARNING
G
Child restraint systems or their securing systems which have been damaged or subjected
to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the securing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again.
If it is absolutely necessary to carry a child on
the front-passenger seat, be sure to observe
the information on the "Occupant Classification System (OCS)" (Y page 53). There you
will also find information on deactivating the
front-passenger front air bag.
All child restraint systems must meet the following standards:
R
U.S. Federal Motor Vehicle Safety Standards 213 and 225
R
Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found
on an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are included with the child restraint system.
Observe the warning labels in the vehicle interior and on the child restraint system.
LATCH-type (ISOFIX) child seat securing system
WARNING
G
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt
integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
Always comply with the manufacturer's
installation and operating instructions for the
child restraint system used.
Before every trip, make sure that the LATCHtype (ISOFIX) child restraint system is
engaged correctly in both LATCH-type (ISOFIX) securing rings
When installing the child restraint system,

Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the
Safety
vehicle's seat belt system. Install child seats
according to the manufacturer's instructions.
Top Tether
Introduction
Top Tether provides an additional connection
between a child restraint system, secured
with a LATCH-type (ISOFIX) child seat mount,
and the rear seat. This helps reduce the risk of
injury even further. If the child restraint system has a Top Tether belt, this should be used
at all times.
Important safety notes
WARNING
G
If the rear seats or the rear seat backrests are
not locked, they could fold forwards in the
event of an accident, heavy braking or sudden
changes of direction. As a result, child
restraint systems cannot perform their intended protective function. Rear seats and rear
seat backrests that are not locked can also
cause additional injuries, e.g. in the event of
an accident. This poses an increased risk of
injury or even fatal injury.
Always lock the rear seats and rear seat
backrests after installing a Top Tether belt.

Child restraint system on the frontpassenger seat
General notes
Accident statistics show that children
secured in the rear seats are safer than children secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat.
If it is absolutely necessary to install a child
restraint system to the front-passenger seat,
be sure to observe the instructions and safety
notes on the "Occupant classification system
(OCS)" (Y page 53).
You can thus avoid the risks that could arise
as a result of:
R
an incorrectly categorized person in the
front-passenger seat
R
the unintentional deactivation of the frontpassenger front air bag
R
the unsuitable positioning of the child
restraint system, e.g. too close to the dashboard
indicator lamp is permanently lit (Y page 45)
is the front-passenger front air bag deactivated.
Always observe the child restraint system
manufacturer's installation and operating
instructions.
Forward-facing child restraint system
If it is absolutely necessary to install a
forward-facing child restraint system on the
front-passenger seat, always move the frontpassenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the frontpassenger seat. The backrest of the child
restraint system must, as far as possible, lie
flat against the backrest of the frontpassenger seat. The child restraint system
must not touch the roof or be put under strain
by the head restraint. Adjust the angle of the
seat backrest and the head restraint position
accordingly. Always make sure that the shoulder belt strap is correctly routed from the
vehicle belt sash guide to the shoulder belt
guide on the child restraint system. The shoulder belt strap must be routed forwards and
downwards from the vehicle belt sash guide.
If necessary, adjust the vehicle belt sash
guide and the front-passenger seat accordingly.
Always observe the child restraint system
manufacturer's installation and operating
instructions.

Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety systems can neither reduce the risk of accident
nor override the laws of physics. Driving
safety systems are merely aids designed to
assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed
and for braking in good time. Always adapt
your driving style to suit the prevailing road
and weather conditions and maintain a safe
distance from the vehicle in front. Drive carefully.
The driving safety systems described only
i
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special attention to the notes on tires, recommended
minimum tire tread depths, etc.
(Y page 400).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,

snow chains. Only in this way will the driving safety systems described in this section
work as effectively as possible.
ABS (Anti-lock Braking System)
General information
Safety
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehicle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Important safety notes
Observe the "Important safety notes" sec-
i
tion (Y page 67).
WARNING
G
If ABS is faulty, the wheels could lock when
braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents.
Drive on carefully. Have ABS checked immediately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 320) and
display messages which may be shown in the
instrument cluster (Y page 285).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even
when you only brake gently.
Braking
X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking situation is over.
X
To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while
driving.
Off-road ABS
An ABS system specifically suited to off-road
terrain is activated automatically once the offroad program is activated (Y page 251).
At speeds below 20 mph (30 km/h), the front
wheels lock cyclically during braking. The digging-in effect achieved in the process reduces
the stopping distance on off-road terrain. This
limits steering capability.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situations. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes
Observe the "Important safety notes" sec-
i
tion (Y page 67).
WARNING
G
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Page 71
Driving safety systems
69
Braking
X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
BAS PLUS (Brake Assist System
PLUS)
General information
Observe the "Important safety notes" sec-
i
tion (Y page 67).
BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS.
For BAS PLUS to assist you, the radar sensor
system must be operational.
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS.
BAS PLUS can help you to minimize the risk of
a collision with a vehicle or reduce the effects
of such a collision. If BAS PLUS detects a
danger of collision, you are assisted when
braking.
Important safety notes
WARNING
G
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
R
intervene unnecessarily
R
not intervene
There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
WARNING
G
BAS PLUS does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake.
In the event of snowfall or heavy rain, the recognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R
dirt on the sensors or anything else covering the sensors
R
there is interference by other radar sources
R
there are strong radar reflections, for
example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible
damage to the front of the vehicle.
Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R
you approach an obstacle, and
R
BAS PLUS has detected a risk of collision
When driving at a speed under 20 mph
(30 km/h): if you depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last possible moment.
Safety
Z
Page 72
Driving safety systems
70
When driving at a speed above 20 mph
(30 km/h): if you depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the traffic situation.
BAS PLUS provides braking assistance in hazardous situations with vehicles in front within
a speed range between 4 mph (7 km/h) and
Safety
155 mph (250 km/h).
At speeds of up to approximately 40 mph
(70 km/h), BAS PLUS can also react to stationary objects. Examples of stationary
objects are stopped or parked vehicles.
If BAS PLUS demands particularly high
i
braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes function as usual again, if:
R
you release the brake pedal.
R
there is no longer a risk of collision.
R
no obstacle is detected in front of your
vehicle.
If you have activated DSR (Y page 250), BAS
PLUS is likewise deactivated.
COLLISION PREVENTION ASSIST
General notes
COLLISION PREVENTION ASSIST consists of
Adaptive Brake Assist and the distance warning function, which are described in the following.
Distance warning function
Important safety notes
Observe the "Important safety notes" sec-
i
tion (Y page 67).
WARNING
G
The distance warning function does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake.
WARNING
G
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R
give an unnecessary warning
R
not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic situation and do not rely solely on the distance
warning function.
Function
X
To activate/deactivate: activate or deactivate the distance warning function in the
on-board computer (Y page 275).
If the distance warning function is not activated, the æ symbol appears in the assistance graphics display.
The distance warning function can help you to
minimize the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically. The
distance warning function cannot prevent a
collision without your intervention.
Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound,
Page 73
Driving safety systems
71
and the · distance warning lamp will light
up in the instrument cluster.
X
Brake immediately in order to increase the
distance from the vehicle in front.
or
X
Take evasive action, provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles that are in the path of your vehicle for an
extended period of time.
Up to a speed of about 40 mph (70 km/h), the
distance warning function can also react to
stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
R
dirt on the sensors or anything else covering the sensors
R
there is snow or heavy rain
R
there is interference by other radar sources
R
there are strong radar reflections, for
example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
R
new vehicles or after the COLLISION PREVENTION ASSIST system has been serviced
Observe the notes in the section on breaking-in (Y page 156).
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensor checked at a qualified specialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Adaptive Brake Assist
Observe the "Important safety notes" sec-
i
tion (Y page 67).
WARNING
G
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situations.
In such cases, Adaptive Brake Assist may:
R
intervene unnecessarily
R
not intervene
There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
WARNING
G
Adaptive Brake Assist does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
to stationary obstacles
R
when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving conditions may also cause Brake Assist to intervene.
Adaptive Brake Assist aids you in braking during hazardous situations at speeds above
4 mph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of Adaptive Brake Assist, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
Safety
Z
Page 74
Driving safety systems
72
Should you approach an obstacle and Adaptive Brake Assist has detected a risk of collision, Adaptive Brake Assist calculates the
braking force necessary to avoid a rear-end
collision. Should you apply the brakes vigorously, Adaptive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions.
Safety
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
R
you release the brake pedal.
R
there is no longer any danger of a collision.
R
no obstacle is detected in front of your
vehicle.
Adaptive Brake Assist is then deactivated.
Vehicles with PRE-SAFE®: if adaptive Brake
Assist requires particularly high brake pressure, preventive passenger protection measures (PRE-SAFE®) are deployed simultaneously.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due to
a malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else covering the sensors
R
there is snow or heavy rain
R
there is interference by other radar sources
R
there are strong radar reflections, for
example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
R
new vehicles or after the COLLISION PREVENTION ASSIST system has been serviced
Observe the notes in the section on breaking-in (Y page 156).
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible
damage to the front of the vehicle.
ESP®(Electronic Stability Program)
General notes
Observe the "Important safety notes" sec-
i
tion (Y page 67).
ESP®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP®assists the driver when
pulling away on wet or slippery roads. ESP
®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
ETS/4ETS traction control is part of ESP®.
Traction control brakes the drive wheels individually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is transferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP®.
In appropriate driving situations, activate the
off-road program (Y page 251).
Page 75

To switch on: press button :.
The å ESP®OFF warning lamp in the
instrument cluster goes out.
Characteristics when ESP®is deactivated
If ESP®is deactivated and one or more wheels
start to spin, the ÷ ESP®warning lamp in
the instrument cluster flashes. In such situations, ESP®will not stabilize the vehicle.
If you deactivate ESP®:
R
ESP®no longer improves driving stability.
R
engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a cutting action for better traction on loose surfaces.
R
traction control is still activated.
R
ESP®still provides support when you
brake.
Off-road ESP®(vehicles with Off-Road
Engineering package)
An ESP®system specifically suited to off-road
terrain is activated automatically once the offroad program is activated (Y page 251).
Off-road ESP®intervenes with a delay if there
is oversteering or understeering, thus improving traction.
ESP®trailer stabilization
General information
ESP®trailer stabilization is not available in
AMG vehicles.
If your vehicle/trailer combination begins to
swerve, ESP®assists you in this situation.
ESP®slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilized.
Important safety notes
WARNING
G
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerving. Trailers with a high center of gravity can
tip over before ESP®can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevailing road and weather conditions.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
Trailer stabilisation is active above speeds of
about 37 mph (60 km/h).

ESP®trailer stabilization does not work if
ESP®is deactivated or disabled because of a
malfunction.
EBD (Electronic Brake force Distribution)
General information
EBD monitors and controls the brake pressure on the rear wheels to improve driving
stability while braking.
Important safety notes
Observe the "Important safety notes" sec-
i
tion for driving safety systems (Y page 67).
WARNING
G
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 321) as well as display messages (Y page 287).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 210)and
hill start assist (Y page 161).
PRE-SAFE®Brake
General information
Observe the "Important safety notes" sec-
i
tion (Y page 67).
PRE-SAFE®Brake is only available in vehicles
with DISTRONIC PLUS.
For PRE-SAFE®Brake to assist you when driving, the radar sensor system must be operational.
With the help of the radar sensor system,
PRE-SAFE®Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE®Brake can help you to minimize
the risk of a collision with a vehicle ahead, and
reduce the effects of such a collision. If PRESAFE®Brake has detected a risk of collision,
you will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE
®
Brake cannot prevent a collision without your
intervention.
Important safety notes
WARNING
G
PRE-SAFE®Brake will initially brake your vehicle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you also brake. Automatic
emergency braking cannot prevent a collision. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action.
WARNING
G
PRE-SAFE®Brake cannot always clearly identify objects and complex traffic conditions.
In these cases, PRE-SAFE®Brake may:
R
give an unnecessary warning and then
brake the vehicle
R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE®Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a collision, you must apply the brakes yourself.

WARNING
G
PRE-SAFE®Brake does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
As a result, PRE-SAFE®Brake may neither
Safety
give warnings nor intervene in all critical situations. There is a risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake.
In the event of snowfall or heavy rain, the recognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R
dirt on the sensors or anything else covering the sensors
R
interference by other radar sources
R
strong radar reflections, for example in
parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehicle, have the configuration and operation of
the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible
damage to the front of the vehicle.
Function
X
To activate/deactivate: activate or deactivate PRE-SAFE®Brake in the on-board
computer (Y page 276).
If the PRE-SAFE®Brake is not activated, the
æ symbol appears in the multifunction
display.
Starting at a speed of around 4 mph (7 km/h),
this function warns you if you rapidly
approach a vehicle in front. An intermittent
warning tone will then sound and the ·
distance warning lamp will light up in the
instrument cluster.
X
Brake immediately to defuse the situation.
or
X
Take evasive action provided it is safe to do
so.
PRE-SAFE®Brake can also brake the vehicle
automatically under the following conditions:
R
the driver and front-passenger have their
seat belts fastened
and
R
the vehicle speed is between approximately 4 mph (7 km/h) and 124 mph
(200 km/h)
At speeds of up to approximately 40 mph
(70 km/h) PRE-SAFE®Brake can also detect
stationary objects. Examples of stationary
objects are stopped or parked vehicles.
If there is an increased risk of collision,
i
preventive passenger protection measures
(PRE-SAFE®) are activated.
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
up to the point of full brake application. Automatic emergency braking is not performed
until immediately prior to an imminent accident.
You can prevent the intervention of the PRESAFE®Brake at any time by:
R
depressing the accelerator pedal further.
R
activating kickdown.
R
releasing the brake pedal.
The braking action of PRE-SAFE®Brake is
ended automatically if:
R
you maneuver to avoid the obstacle.
R
there is no longer any danger of a collision.
R
there is no longer an obstacle detected in
front of your vehicle.
If you have activated DSR (Y page 250), PRESAFE®Brake is deactivated.
