Protection of 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 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
H
Environmental note
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 Devices, 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.

Introduction
Page 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.

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 350).

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
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.
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
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.
Introduction
25
Z
Page 28
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.

Limited Warranty
!
Follow the instructions in this manual
about the proper operation of your vehicle
as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions is not covered either by the
Mercedes-Benz Limited Warranty or by the
New or Used-Vehicle Warranty.
Data stored in the vehicle
Data recording
This vehicle is capable of recording diagnostic
information relating to vehicle operation, malfunctions, and user settings. This may include
information about the performance or status
of various systems, including but not limited
to, engine, throttle, steering or brake systems, that is stored and can be read out with
suitable devices, particularly when the vehicle is serviced. The data obtained is used to
properly diagnose and service your vehicle or
to further optimize and develop vehicle functions.
COMAND/mbrace (Canada: TELEAID)
If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle’s
operation, the use of the vehicle in certain
situations, and the location of the vehicle may
be compiled through COMAND or the mbrace
system.
For additional information please refer to the
COMAND User Manual and/or the mbrace
Terms and Conditions.
Event data recorders
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record data that will assist in understanding how a vehicle’s systems performed
in certain crash or near crash-like situations,
such as during air bag deployment or when
hitting a road obstacle. 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 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
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.
To read data recorded by an EDR, special
equipment is required, and access to the vehicle or the EDR is needed. 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
28
Introduction
Page 31
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
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
Restraint system: introduction
The restraint system reduces 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 46)
R
have adjusted their seat and head restraint
properly (Y page 97).
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 96).
You also have to make sure that an air bag can
inflate properly if deployed (Y page 48).
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 Device and air bags"
(Y page 56).
For more information about children traveling
with you in the vehicle and on child restraint
systems, see "Children in the vehicle"

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 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

(Y page 48). 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 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, seat belt force limiters help
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 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.
G
WARNING
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 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.
G
WARNING
The seat belt does not offer the intended level
of protection if you have not moved the back-
44

rest 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 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.
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
(Y page 58) 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 51)
G
WARNING
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. Any such
modifications could invalidate the vehicle's
general operating permit.
Vehicles with a sports seat or AMG Performance seat: these seats are designed for
the standard three-point seat belt. If you
install another multipoint seat belt, e.g. sport
or racing seat belts, the restraint system cannot provide the best level of protection.
G
WARNING
If you feed seat belts through the opening in
the seat backrest, the seat backrest may be
damaged or may even break in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
Only use the standard three-point seat belt.
Never modify the seat belt system.

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.
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. Where 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,

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 seat belt
has 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 again. 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
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
Occupant safety

warning tone sounds. The warning tone
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.

For more information on the 7 seat
belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat
belts" (Y page 247).
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 56).
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 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.
48
Occupant safety
Safety
Page 51
R
Only secure a child in a rearward-facing
child restraint system on the frontpassenger seat when the front-passenger
front air bag is deactivated. If the
PASSENGER AIR BAG OFF indicator lamp is
permanently lit, the front-passenger front
air bag is deactivated (Y page 43).
R
Always observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (Y page 51) and on "Children
in the vehicle" (Y page 58) 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.
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
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 : 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 and
PASSENGER AIR BAG ON indicator lamps
inform you about the status of the frontpassenger front air bag (Y page 43).
Front-passenger front air bag ; will only
deploy if:
R
the system, based on the OCS weight sensor readings, detects that the frontpassenger seat is occupied (Y page 51).

The driver's and front-passenger knee bags
offer additional thigh, knee and lower leg protection for the occupants in the front seats.
Side impact air bags
G
WARNING
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 ; 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
In the event of 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 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 belt
buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the side impact air bag on the frontpassenger side deploys if an appropriate accident situation occurs. In this case, deployment is independent of whether the frontpassenger 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.
50
Occupant safety
Safety
Page 53
However, it does not protect the 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 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 56).
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 and front-passenger
knee bag are 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
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
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.

PASSENGER AIR BAG OFF indicator lamps. Be
aware of the status of the front-passenger
front air bag both before and during the journey.
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.
G
WARNING
If you secure a child in a rearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenger front air bag
may deploy in 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.
If the PASSENGER AIR BAG OFF indicator
lamp remains off and/or the PASSENGER AIR
BAG ON indicator lamp lights up, 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 55).
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 ON is lit up
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 outlet to the shoulder belt guide on the
child restraint system. The shoulder belt strap
must be routed forwards and downwards
from the vehicle belt outlet. If necessary,
adjust the vehicle belt outlet and the frontpassenger 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 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 ON can light up permanently 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), either the PASSENGER AIR
BAG ON or PASSENGER AIR BAG OFF indicator lamp lights up and remains lit after
the system self-test depending on the
result of the classification.
-
If the PASSENGER AIR BAG ON indicator
lamp lights up, 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 a stature corresponding to that of an adult, the PASSENGER AIR
BAG ON indicator lamp lights up after the
system self-test and remains lit. 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 58).
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

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.

DANGER
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 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 person is seated properly with a correctly fastened seatbelt
R
the front-passenger seat has been moved
back 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 forwards-
facing 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 display the status of the frontpassenger front air bag (Y page 51).

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
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.
If 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 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. To avoid this, you may wish to get out of
the vehicle or open the windows as soon as it
is safe to do so.
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 deploys the
Emergency Tensioning Devices during a frontal or rear collision.
An Emergency Tensioning Device can only be
deployed, if:
R
the ignition is switched on
R
the components of the restraint system are
operational; see "Restraint system warning
lamp" (Y page 43)
R
the belt tongue is engaged in the buckle on
the respective front-passenger seat
The Emergency Tensioning Devices in the
rear compartment are deployed independently of the lock status of the seat belts.
56
Occupant safety
Safety
Page 59
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 as well as driver's and frontpassenger knee bags
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 frontpassenger front air bag can only deploy in an
accident if the PASSENGER AIR BAG ON indicator lamp is lit. Observe the information on
the PASSENGER AIR BAG indicator lamps
(Y page 43).
Your vehicle has two-stage front air bags.
During the first deployment stage, the front
air bag is filled with propellant gas to reduce
the risk of injuries. The front air bag is fully
deployed with the maximum amount of propellant gas if a second deployment threshold
is reached within a few milliseconds.
The deployment threshold of the Emergency
Tensioning Devices and the air bag are determined by evaluating the rate of vehicle deceleration or acceleration which occurs at various points in the vehicle. This process is preemptive 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 or that the vehicle is rolling over,
the relevant restraint system components are
activated independently of one another
depending on the apparent type of accident.
If the system determines a need for additional
protection for the vehicle occupants, the
Emergency Tensioning Devices are deployed.
R
Side impact air bags on the side of impact,
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 (front) deploys in the following situations:
-
the OCS system detects that the frontpassenger seat is occupied or
-
the belt 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
front-passenger seat is occupied
R
Window curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer additional protection to that provided by the
seat belt
i
Not all air bags are deployed in an accident. The different air bag systems work
independently of each other.

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 51)
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

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 260).
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.
Securing systems for the child restraint system are:
R
the seat belt system
R
the ISOFIX (LATCH-type) securing rings
R
the Top Tether anchorages
i
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 51).
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
G
WARNING
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.

and the vehicle. This helps reduce the risk of
injury even further. If the child restraint system is equipped with a Top Tether belt, this
should always be used.
Important safety notes
G
WARNING
If 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 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 rear seat backrests after installing a Top Tether belt. Observe the lock verification indicator. Adjust the rear seat backrests so that they are in an upright position.
If the rear backrest is not engaged and

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
Rearward-facing child restraint system
If it is absolutely necessary to install a rearward-facing child restraint system on the
front-passenger seat, always make sure that
the front-passenger front air bag is deactivated. Only if the PASSENGER AIR BAG OFF
indicator lamp is permanently lit (Y page 43)
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 shoul-

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,
weather and traffic conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
64
Driving safety systems
Safety
Page 67
i
The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Pay particular attention to
the information regarding tires, recommended minimum tire tread depths etc. in the
"Wheels and tires" section (Y page 318).
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.
Important safety notes
i
Observe the "Important safety notes" section for driving safety systems (Y page 64).
G
WARNING
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 249) and
display messages which may be shown in the
instrument cluster (Y page 217).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery roads, even if
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.
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 64).
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.

COLLISION PREVENTION ASSIST
General notes
COLLISION PREVENTION ASSIST consists of
the Adaptive Brake Assist and the distance
warning function, which are described in the
following.
Distance warning function
Important safety notes
i
Observe the "Important safety notes" sec-
tion (Y page 64).
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
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.
G
WARNING
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 208).
If the distance warning function is activated,
the Ä symbol appears in the assistance
graphics display.
The distance warning function can help you to
minimize the risk of a 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. Without
your intervention, the distance warning function cannot prevent a collision.
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,
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
66
Driving safety systems
Safety
Page 69
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 a service on the COLLISION PREVENTION ASSIST PLUS system
Observe the notes in the section on breaking-in (Y page 142).
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.
Adaptive Brake Assist
i
Observe the "Important safety notes" section for driving safety systems (Y page 64).
G
WARNING
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.
G
WARNING
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 a sensor system, adaptive
Brake Assist can detect obstacles that are in
the path of your vehicle for an extended
period of time.
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.
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, preventative passenger protection
measures (PRE-SAFE®) are deployed simultaneously.
Up to vehicle speeds of around 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.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable
Driving safety systems
67
Safety
Z
Page 70
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 a service on the COLLISION PREVENTION ASSIST PLUS system
Observe the notes in the section on breaking-in (Y page 142).
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.
COLLISION PREVENTION ASSIST PLUS
General information
COLLISION PREVENTION ASSIST PLUS is
only available on vehicles with DISTRONIC.
COLLISION PREVENTION ASSIST PLUS
extends the functionality of COLLISION PREVENTION ASSIST with an automatic braking
function. COLLISION PREVENTION ASSIST
PLUS 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 COLLISION PREVENTION ASSIST PLUS detects
that there is a risk of a collision, you will be
warned visually and acoustically. In critical
situations COLLISION PREVENTION ASSIST
PLUS also initiates automatic braking.
Function
X
To activate/deactivate: activate or deactivate COLLISION PREVENTION ASSIST
PLUS in the on-board computer
(Y page 208).
If COLLISION PREVENTION ASSIST PLUS is
activated, the Ä symbol appears in the
assistance graphics display.
If the driver's seat belt is fastened, COLLISION PREVENTION ASSIST PLUS can brake
automatically within a speed range of
between 4 mph (7 km/h) and 124 mph
(200 km/h).
COLLISION PREVENTION ASSIST PLUS can
also react to stationary obstacles with automatic braking within a speed range of
between 4 mph (7 km/h) and 19 mph
(30 km/h).
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

ESP®(Electronic Stability Program)
General notes
i
Observe the "Important safety notes" section (Y page 64).
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" section (Y page 64).
ETS/4ETS traction control is part of ESP®.
ETS 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.
ETS remains active when you deactivate
ESP®.
Important safety notes
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.

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
