Protecting the environment
General notes
H
Environmental note
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 Operator's Manual requires you to
dispose of materials, first try to regenerate or reuse them. Observe the relevant environmental
rules and regulations when disposing of materials. In this way you will help to protect the environment.

Operating safety
Important safety notes
G
WARNING
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.
G
WARNING
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.
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.
G
WARNING
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

Operating safety
25
Introduction
Z
!
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, a speed bump or a pothole in the road
R
a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the underbody, 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 loads 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, consult a qualified specialist workshop.

ply with Part 15 of the FCC Rules. Operation is
subject to the two following two conditions: 1)
These devices may not cause harmful interference, and 2) These devices must accept any
interference received, including interference
that may cause undesired operation. Changes
or modifications not expressly approved by the
party responsible for compliance could void the
user’s authority to operate the equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the following two conditions: (1) These devices may
not cause interference, and (2) These devices
must accept any interference, including interference that may cause undesired operation of

ment, intervention of stability control systems
R
ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
R
assist in recognizing and rectifying malfunctions and defects
R
analyze vehicle functions, e.g. after an accident
R
optimize vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical information can be read from the event data memory
and malfunction data memory.
Services include, for example:
R
repair services
R
service processes
R
warranties
R
quality assurance
The vehicle is read out by employees of the service network (including the manufacturer) using
special diagnostic testers. More detailed information is obtained from it, if required.
After a malfunction has been rectified, the information is deleted from the malfunction memory
or is continually overwritten.
When operating the vehicle, situations are conceivable in which this technical data, in connection with other information (if necessary, under
consultation with an authorized expert), could
be traced to a person.
Examples include:
R
accident reports
R
damage to the vehicle
R
witness statements
Further additional functions that have been contractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehicle as well. The additional functions include, for
example, vehicle location in case of an emergency.
Event data recorders
This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle's systems
performed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less.
The EDR in this vehicle is designed to record
such data as:
R
How various systems in your vehicle were
operating
R
Whether or not the driver and passenger
safety belts were buckled/fastened
R
How far (if at all) the driver was depressing the
accelerator and/or brake pedal and
R
How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in which crashes
and injuries occur. NOTE: EDR data are recorded
by your vehicle only if a non-trivial crash situation occurs; no data are 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 could combine the EDR data
with the type of personally identifying 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.

Data stored in the vehicle
Introduction
Warning: The EDR is a component of the
Restraint System Module. Tampering with, altering, modifying or removing the EDR component
may result in a malfunction of the Restraint System 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
Introduction to the restraint system
The restraint system can reduce the risk of vehicle occupants coming into contact with parts of
the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces
to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
R
Seat belt system
R
Air bags
R
Child restraint system
R
Child seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all
vehicle occupants:
R
have fastened their seat belts correctly
(Y page 40)
R
have the seat and head restraint adjusted
properly (Y page 83)
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (Y page 83).
You also have to make sure that an air bag can
inflate properly if deployed (Y page 42).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For example, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags
are not deployed. When an accident occurs, only
the air bags that increase protection in that particular accident situation are deployed. However, seat belts and air bags generally do not
protect against objects penetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (Y page 49).
See "Children in the vehicle" for information on
children traveling with you in the vehicle as well
as on child restraint systems (Y page 50).
Important safety notes
G
WARNING
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 components of the
restraint system to accommodate a person with
disabilities, contact an authorized MercedesBenz Center for details. USA only: for further
information contact our Customer Assistance
Center at 1-800 FOR-MERCEDES
(1‑800‑367‑6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifically for your vehicle by Mercedes-Benz.

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 on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few seconds after the vehicle 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
G
WARNING
If the restraint system is malfunctioning,
restraint system components may be triggered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. 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 indicator lamp
PASSENGER AIR BAG ON indicator lamp : and
PASSENGER AIR BAG OFF indicator lamp ; are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag.
R
PASSENGER AIR BAG ON lights up for 60 seconds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy
in the event of an accident.
R
PASSENGER AIR BAG OFF lights up: the frontpassenger front air bag is deactivated. It will
then not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator
lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated 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 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 44) and on "Children in the vehicle" (Y page 50). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
R
All other persons: depending on the classification of the person in the front-passenger
seat, the front-passenger front air bag is enabled or deactivated (Y page 44). Be sure to
observe the notes on "Seat
belts“ (Y page 38) and "Air bags"
(Y page 42). There you can also find information on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Furthermore, the seat belt helps to keep the vehicle
38
Occupant safety
Safety
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
R
Seat belts
R
Emergency Tensioning Devices for the front
seat belts and the outer seat belts in the rear
R
Seat belt force limiters for the front seat belts
and the outer seat belts in the rear
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extracted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not correct an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle occupants during an accident.
!
If the front-passenger seat is not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Otherwise, in the event of an accident the Emergency Tensioning Device and the side impact
air bag, in addition to other systems, may be
triggered and have 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.
G
WARNING
If the seat belt is not worn correctly, it cannot
perform its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an accident or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting properly.
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all
vehicle occupants:
R
have fastened their seat belts correctly
(Y page 40)
R
have the seat and head restraint adjusted
properly (Y page 83)
G
WARNING
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.
G
WARNING
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an additional and suitable restraint system. If the
seat belt is not worn correctly, it cannot perform its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an accident or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) tall in suitable additional restraint
systems.
Occupant safety

If a child younger than twelve years old 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 on "Children in the vehicle"
(Y page 50) in addition to the child restraint
system manufacturer's installation and operating instructions
R
always observe the instructions and safety
notes on the "Occupant classification system

G
WARNING
The seat belts may not perform their intended
protective function if:
R
they are damaged, modified, extremely
dirty, bleached 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 and 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.
Proper use of the seat belts
Observe the safety notes on the seat belt
(Y page 39).
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 buckle tongue is inserted only
into the belt buckle belonging to that seat
R
the seat belt is pulled tight across your body
Avoid wearing bulky clothing, e.g. a winter
coat.
R
the seat belt is not twisted
Only then can the forces which occur be dis-
tributed over the area of the belt.
R
the shoulder section of the belt is routed
across the center of your shoulder
The shoulder section of the seat belt should
not touch your neck or be routed under your
arm or behind your back. Where possible,
adjust the seat belt to the appropriate height.
R
the lap belt is taut and passes across your lap
as low down as possible
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
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
Also ensure that there are never objects
between a person and the seat, e.g. cushions.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe the
"Loading guidelines" for securing objects, luggage or loads (Y page 221).

Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the instrument cluster is a reminder that all vehicle occupants must wear their seat belts. It may light up
continuously or flash. In addition, there may be
a warning tone.
Regardless of whether the driver's seat belt has
already been fastened, the 7 seat belt warning lamp lights up for six seconds each time the
engine is started. If the front doors are closed
and the driver's or front-passenger seat belt has
not been fastened, the 7 seat belt warning
lamp lights up again after the six seconds. 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. The warning tone switches off after six
seconds or once 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 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.

Air bags
Introduction
The installation point of an air bag can be recognized by the AIRBAG marking.
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 49).
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
G
WARNING
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 forward 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 twelve years of
age and less than 5 ft (1.50 m) tall in suitable
child restraint systems.
R
Child restraint systems should be installed on
the rear seats.
R
Only secure a child in a rearward-facing child
restraint system on the front-passenger seat
when the front-passenger front air bag is
deactivated. If the PASSENGER AIR BAG OFF
indicator lamp is permanently lit, the frontpassenger front air bag is deactivated
(Y page 38).
R
Always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (Y page 44) and on "Children in the
vehicle" (Y page 50)in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may prevent
an 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
there are no hard objects, e.g. coat hangers,
hanging 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
G
WARNING
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.
G
WARNING
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
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. 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
!
Do not place heavy objects on the frontpassenger seat. This could cause the system
to identify the seat as being occupied. In the
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced.
Driver's air bag : deploys in front of the steering wheel. Front-passenger front air bag ;
deploys in front of and above the glove box.
When deployed, the front air bags offer additional head and thorax protection for the occupants in the front seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the frontpassenger front air bag (Y page 38).
The front-passenger front air bag will only
deploy if:
R
the system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied (Y page 44). The
PASSENGER AIR BAG OFF indicator lamp is
not lit (Y page 45)
R
the restraint system control unit predicts a
high accident severity
Driver's knee bag
Driver's knee bag : deploys under the steering
column. The driver's knee bag is deployed

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
G
WARNING
Unsuitable seat covers can obstruct or prevent 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 operation of
the occupant classification system (OCS)
could be adversely affected. 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.

Safety
Z
Front side impact air bags : and rear side
impact air bags ; deploy next to the outer bolster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. It also offers additional pelvis protection for occupants in the
front seats. However, it does not protect the:
R
Head
R
Neck
R
Arms
If the restraint system control unit detects a side
impact, the side impact air bag is deployed on
the side on which the impact occurs.
The side impact air bag on the front-passenger
side deploys under the following conditions:
R
the OCS system detects that the frontpassenger seat is occupied or
R
the seat belt buckle tongue is engaged in the
belt buckle of the front-passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front-passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent
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 deployed in the
area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or arms.
If the restraint system control unit detects a side
impact, the window curtain air bag is deployed
on the side on which the impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
(Y page 49).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) categorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
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
Requirements
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
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. a
cushion. The entire base of the child restraint
system must always rest on the seat cushion of
44
Occupant safety
Safety
the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as
flat as possible against the backrest of the frontpassenger seat.
The child restraint system must not touch the
roof or be subjected to a load 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 and operating
instructions.

G
WARNING
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 disabled 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.

Safety
Z
Make sure that the front-passenger front air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE FRONT AIRBAG in front of it; DEATH or SERIOUS INJURY
to the child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not install a rearward-facing child
restraint system on the front-passenger seat.
You can find more information on OCS under
"Problems with the Occupant Classification System" (Y page 48).
G
WARNING
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, in the event of an
accident, the child could:
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.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. 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.
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 twelve 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 even in the case of a twelve-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 child
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 smaller 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 adult stature, 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 50).
When the Occupant Classification System
(OCS) is malfunctioning, the red 6 restraint
system warning lamp on the instrument cluster
and the PASSENGER AIR BAG OFF indicator
lamp light up simultaneously. The frontpassenger front air bag is deactivated in this
case and does not deploy during an accident.
Have the Occupant Classification System (OCS)
checked and repaired immediately at a qualified
specialist workshop. Mercedes-Benz recommends that you use an authorized MercedesBenz Center for this purpose.

you use an authorized Mercedes-Benz Center
for this purpose.
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 on the
front-passenger seat. Depending on that result,
the front-passenger front air bag is either enabled or deactivated.
System self-test
G
DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The frontpassenger 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.
G
WARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the
front-passenger front air bag is disabled. It will
not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective function, e.g. when a person is seated in the frontpassenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. 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 disabled in accordance with the person in the
front-passenger seat
R
the person is seated properly with a correctly fastened seatbelt
R
the front-passenger seat has been moved
as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the frontpassenger seat may not be used. Do not
install a child restraint system on the frontpassenger seat. Have the Occupant Classification System (OCS) checked and repaired
immediately at a qualified specialist workshop.
G
WARNING
Objects between the seat surface and the
child restraint system could affect OCS operation. This could result in the front-passenger
air bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the frontpassenger seat. The backrest of the forwardfacing child restraint system must, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with the
child restraint system manufacturer's installation instructions.
After the system self-test, the PASSENGER AIR
BAG OFF or PASSENGER AIR BAG ON indicator
lamp displays the status of the front-passenger
front air bag (Y page 45). If the front-passenger
front air bag is enabled, the PASSENGER AIR

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes
G
WARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified specialist workshop as soon as possible.
G
WARNING
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 your
passenger 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.
G
WARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer operational and are unable to perform their intended protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at a
qualified specialist workshop.
If Emergency Tensioning Devices are triggered
or air bags are deployed, you will hear a bang,
and some powder may also be released. The
6 restraint system warning lamp lights up.
Only in rare cases will the bang affect your hearing. The powder that is released generally does
not constitute a health hazard, but it may cause
short-term breathing difficulties in people with
asthma or other respiratory problems. Provided
it is safe to do so, you should leave the vehicle
immediately or open the window in order to prevent breathing difficulties.
Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. National guidelines must
be observed during disposal. In California, 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 Emergency Tensioning Devices during a frontal or
rear collision.
An Emergency Tensioning Device can only be
triggered, if:
R
the ignition is switched on
R
the components of the restraint system are
operational. You can find further information
under "Restraint system warning lamp"
(Y page 38)
R
the seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The Emergency Tensioning Devices in the rear
compartment are triggered independently of the
lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independently of each other in certain frontal collision
situations:
R
Front air bags and driver's knee bag
R
Window curtain air bag, if the system determines that deployment can offer additional
protection to that provided by the seat belt
The front-passenger front air bag is activated or
deactivated depending on the person on the
front-passenger seat. The front-passenger front
air bag can only deploy in an accident if the
PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BAG indicator lamps (Y page 38).
Your vehicle has two-stage front air bags. In the
first deployment stage, the front air bag is filled
with propellant gas. The front air bag is fully
Occupant safety
49
Safety
Z
deployed with the maximum amount of propellant gas if a second deployment threshold is
reached within a few milliseconds.
The activation threshold of the Emergency Tensioning Devices and the air bags is determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various points in
the vehicle. This process is pre-emptive in
nature. Deployment should take place in good
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
the distribution of forces during the collision
R
the collision angle
R
the deformation characteristics of the vehicle
R
the characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a decisive role in the deployment of an air bag. Nor do
they provide an indication of air bag deployment.
The vehicle can be deformed considerably, without an air bag being deployed. This is the case if
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deformation. This is the case if, for example, very rigid
vehicle parts such as longitudinal body members are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact, the relevant restraint system components are deployed independently of each other.
R
Side impact air bags on the side where the
impact takes place, independently of the
Emergency Tensioning Device and the use of
the seat belt on the driver's seat and outer
seats in the second row
The side impact air bag on the frontpassenger side deploys under the following
conditions:
-
the OCS system detects that the frontpassenger seat is occupied or
-
the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
R
Window curtain air bag on the side of impact,
independently of the use of the seat belt and
independently of whether the frontpassenger seat is occupied
R
Emergency Tensioning Devices, if the system
determines that deployment can offer additional protection in this situation
i
Not all air bags are deployed in an accident.
The different air bag systems work independently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or acceleration and the apparent type of accident:
R
Frontal collision
R
Side impact
Automatic measures after an accident
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
R
the hazard warning lamps are activated
R
the emergency lighting is activated
R
the vehicle doors are unlocked
R
the front side windows are lowered
R
the engine is switched off and the fuel supply
is cut off
R

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 twelve years old 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

G
WARNING
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.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
G
WARNING
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.
G
WARNING
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 39) and the notes on correct use of seat
belts (Y page 40).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
40 lbs (18 kg) until they reach a height where a
three-point seat belt can be properly fastened
without a booster seat.
Special seatbelt retractor
G
WARNING
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
portion of the seat belt. The seat belt cannot
be immediately refastened. There is an
increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying attention to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts in the vehicle, except the driver's
seat belt, are equipped with a special seat belt

G
WARNING
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.
G
WARNING
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 221).
G
WARNING
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.
The securing systems of child restraint systems
are:
R
the seat belt system
R
the LATCH-type (ISOFIX) securing rings
R
the Top Tether anchorages
If it is absolutely necessary to carry a child on
the front-passenger seat, be sure to observe the
information on the "Occupant Classification

LATCH-type (ISOFIX) child seat securing system
G
WARNING
For LATCH-type (ISOFIX) child restraint systems in which the child is secured using the
safety belt integrated in the child restraint
system, the maximum permissible weight of
the child and child restraint system together
is 73 lbs (33 kg).
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated safety belt no longer offers
sufficient protection. The LATCH-type (ISOFIX) child seat securing system may be overloaded, and the child may not be restrained in
an accident, for example. This poses an
increased risk of injury or even fatal injury.
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), use
only a LATCH-type (ISOFIX) child restraint system in which the child is also secured with the
vehicle seat belt. Also secure the child
restraint system with the Top Tether belt, if
available.
Regularly check that the permissible gross
weight of the child together with the child
restraint system is still maintained.
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

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
the child restraint system on a rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (Y page 44).
You can thus avoid the risks that could arise as
a result of:
R
an incorrectly categorized person in the frontpassenger 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
Rearward-facing child restraint system

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 forwardfacing child restraint system on the frontpassenger seat, always move the frontpassenger seat as far back as possible. Fully
retract the seat cushion length. The entire base
of the child restraint system must always rest on
the seat cushion of the front-passenger seat.
The backrest of the child restraint system must
lie as flat as possible against the backrest of the
front-passenger seat. The child restraint system
must not touch the roof or be subjected to a load
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 outlet to the shoulder belt guide on the
child restraint system. The shoulder belt strap
must be routed forward and down from the vehicle belt outlet. If necessary, adjust the vehicle
belt outlet 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 if you are
inattentive, the driving safety systems can neither reduce the risk of an accident nor override
the laws of physics. Driving safety systems are
merely aids designed to assist driving.
56
Driving safety systems
Safety
You are responsible for maintaining the distance
to the vehicle in front, for vehicle speed, for
braking in good time, and for staying in lane.
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 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 270).
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
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.
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.
Important safety notes
i
Observe the "Important safety notes" section (Y page 56).
G
WARNING
If ABS is malfunctioning, the wheels could
lock when braking. The steerability and braking characteristics would be severely affected. 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 206) and display messages which may be shown in the
instrument cluster (Y page 179).
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.
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
i
Observe the "Important safety notes" sec-
tion (Y page 56).
G
WARNING
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.
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.

Z
Active Brake Assist
General information
i
Observe the "Important safety notes" sec-
tion (Y page 56).
Active Brake Assist consists of a distance warning function with an autonomous braking function and situation-dependent braking assistance
Active Brake Assist can help you to minimize the
risk of a collision with the vehicle traveling in
front or reduce the effects of such a collision.
If Active Brake Assist detects that there is a risk
of collision, you will be warned visually and
acoustically. If you do not react to the visual and
audible collision warning, autonomous braking
can be initiated in critical situations. If you apply
the brake yourself in a critical situation, Active
Brake Assist supports you with situationdependent braking assistance.
Important safety notes
Detection of hazardous situations can be particularly impaired if:
R
there is 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 is traveling in front, e.g. a
motorbike
R
a vehicle is traveling in front on a different line
R
you are driving a new vehicle or servicing on
the Active Brake Assist system has just been
carried out
Observe the important safety notes in the
"Breaking-in notes" section (Y page 113).
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 no visible damage to the front of
the vehicle is apparent.
Activating/deactivating
Active Brake Assist is active after every ignition
cycle.
You can activate or deactivate Active Brake
Assist (Y page 174) in the on-board computer.
When deactivated, the distance warning function and the autonomous braking function are
also deactivated.
Vehicles with a black and white multifunction display: when Active Brake Assist is acti-
vated, the Ä symbol appears in the status
overview of the multifunction display.
Vehicles with a color multifunction display:
when Active Brake Assist is deactivated, the
æ symbol appears in the assistance graphic
display of the multifunction display.
Distance warning function
General information
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.
Important safety notes
i
Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 56).
G
WARNING
The distance warning function does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
The distance warning function may not give
warnings in all critical situations. There is a
risk of an accident.
Always pay careful attention to the traffic situation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions.
G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
58
Driving safety systems
Safety
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
Starting at a speed of approximately 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, 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 approximately 44 mph
(70 km/h), the distance warning function can
also react to stationary obstacles, such as stopped or parked vehicles.
Autonomous braking function
If the driver does not react to the distance warning signal in a critical situation, Active Brake
Assist can assist the driver with the autonomous
braking function.
The autonomous braking function:
R
gives the driver more time to react to critical
driving situations
R
can help the driver to avoid an accident or
R
reduces the effects of an accident
Vehicles without Distance Pilot DISTRONIC:
the autonomous braking function is available in
the following speed ranges:
R
4 - 65 mph (7 - 105 km/h) for moving objects
R
4 - 31 mph (7 - 50 km/h) for stationary
objects
Vehicles with Distance Pilot DISTRONIC: the
autonomous braking function is available in the
following speed ranges:
R
4 - 124 mph (7 - 200 km/h) for moving
objects
R
4 - 31 mph (7 - 50 km/h) for stationary
objects
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the Autonomous Braking Function to intervene.
Situation-dependent braking assistance
General information
i
Observe the "Important safety notes" sec-
tion (Y page 56).
With the help of the radar sensor system, Active
Brake Assist can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If Active Brake Assist detects a risk of collision
with the vehicle in front, it calculates the brake
pressure necessary to avoid a collision. If you
apply the brakes forcefully, situation-dependent
braking assistance adapts to the situation and
automatically increases the brake pressure to a
degree appropriate to the traffic situation.
Situation-dependent braking assistance provides braking assistance in hazardous situations
at speeds above 4 mph (7 km/h). It uses radar
sensor technology to assess the traffic situation.
Situation-dependent braking assistance is capable of reacting to moving objects that have
already been detected as such at least once
over the period of observation, up to vehicle
speeds of around 155 mph (250 km/h).
Situation-dependent braking assistance can
also detect stationary objects, up to vehicle
speeds of around 44 mph (70 km/h).
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
Driving safety systems
59
Safety
Z
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.
Situation-dependent braking assistance is then
deactivated.
Important safety notes
i
Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 56).
G
WARNING
Active Brake Assist does not react:
R
to persons, bicycles, motorcycles or animals
R
to approaching vehicles
R
to cross traffic
R
on bends
As a result, Active Brake Assist cannot intervene in all critical situations. There is a risk of
an accident.
Always pay careful attention to the traffic situation and be prepared to brake.
G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situations.
In such cases, Adaptive Brake Assist might:
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.
Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due to
a malfunction in the radar sensor system, the
brake system is still available with full brake
boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
i
Observe the "Important safety notes" sec-
tion (Y page 56).
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)
i
Observe the "Important safety notes" sec-
tion (Y page 56).
ETS traction control is part of ESP®. On vehicles
with 4MATIC, 4ETS 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®.
Important safety notes
i
Observe the "Important safety notes" sec-
tion (Y page 56).
G
WARNING
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
If the å ESP®OFF warning lamp lights up
continuously, ESP®is deactivated.
If the ÷ ESP®warning lamp and the å
warning lamp are lit continuously, ESP®is not
available due to a malfunction.

ESP®trailer stabilization
General information
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
G
WARNING
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.
ESP®trailer stabilization is active above speeds
of about 65 km/h.
ESP®trailer stabilization does not work if ESP
®
is deactivated or disabled because of a malfunction.
