Protection of the environment
General notes
Environmental note
H
Daimler's declared policy is one of comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
R
operating conditions of your vehicle
R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R
avoid short trips as these increase fuel consumption.
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
R
remove roof racks once you no longer need
them.
R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R
always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R
do not depress the accelerator pedal when
starting the engine.
R
do not warm up the engine when the vehicle
is stationary.
R
drive carefully and maintain a safe distance
from the vehicle in front.
R
avoid frequent, sudden acceleration and
braking.
R
change gear in good time and use each gear
only up to Ô of its maximum engine speed.
R
switch off the engine in stationary traffic.
R
keep an eye on the vehicle's fuel consumption.
Environmental concerns and recommendations
Wherever the operating instructions require
you to dispose of materials, first try to regenerate or re-use them. Observe the relevant
environmental rules and regulations when
disposing of materials. In this way you will
help to protect the environment.
Genuine Mercedes-Benz parts
Environmental note
H
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
Air bags and Emergency Tensioning Devi-
!
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R
doors
R
door pillars
R
door sills
R
seats
R
cockpit
R
instrument cluster
R
center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
Introduction
23
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes.
This could lead to malfunctions in safety-relevant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tires, wheels and
accessories that have been specifically
approved for your vehicle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been specifically developed, manufactured or selected
for and adapted to Mercedes-Benz vehicles.
Only genuine Mercedes-Benz parts should
therefore be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.
All authorized Mercedes-Benz Centers maintain a supply of genuine Mercedes-Benz parts
for necessary service and repair work. In addition, strategically located parts delivery centers provide quick and reliable parts service.
Always specify the vehicle identification number (VIN) when ordering genuine MercedesBenz parts (
Y page 399).

Operating safety
Important safety notes
WARNING
G
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/maintenance work as well as any required repairs
carried out at a qualified specialist workshop.
WARNING
G
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.
WARNING
G
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other networked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as intended and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as electronic components or their software. You
should have all work to electrical and electronic equipment carried out at a qualified
specialist workshop.
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
Z
Introduction
26
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,
consult a qualified specialist workshop.

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
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
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
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 47)
(
R
have adjusted their seat and head restraint
properly (
Y page 107).
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 106).
You also have to make sure that an air bag can
inflate properly if deployed (
Y page 50).
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 59).

with you in the vehicle and on child restraint
systems, see "Children in the vehicle"

Important safety notes
WARNING
G
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even
fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify an air bag system to
accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for
details. USA only: for further information contact our Customer Assistance Center at
1-800-FOR-MERCedes (1‑800‑367‑6372).
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the engine is running. Therefore, malfunctions can be detected in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the ignition is switched on. It goes out no later than a
few seconds after the 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
WARNING
G
If restraint system is malfunctioning, restraint
system components may be triggered unintentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emergency Tensioning Device or air bag, for example. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.

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 and seat
belt force limiters
If the seat belt is pulled by the seat belt
extender 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 decelerat
ion 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.
WARNING
G
If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an
incorrectly fastened seat belt can cause additional injury, for example, in an accident, 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.
WARNING
G
The seat belt does not offer the intended level
of protection if you have not moved the backrest to an almost vertical position. When braking or in the event of an accident, you could
slide underneath the seat belt and sustain
Occupant safety
47
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
WARNING
G
Persons under 5 ft (1.50 m) in height cannot
fasten the seat belt correctly without an additional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable restraint
systems.
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

Seat belts may sustain non-visible damage in
an accident, e.g. due to glass splinters. 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.
Proper use of the seat belts

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, after
six seconds, the driver or front-passenger
seat belt has not been fastened and the doors
are closed, the 7 seat belt warning lamp
lights up. As soon as the driver's and frontpassenger 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
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 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 59).
However, no system available today can completely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
WARNING
G
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R
have fastened their seat belts correctly,
including pregnant women
R
are sitting correctly and maintain the greatest possible distance to the air bags
R
follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occupants.
R
Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
R
Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
R
Only hold the steering wheel on the outside. This allows the air bag to be fully
deployed.
R
Always lean against the backrest while driving. Do not lean forwards or lean against
the door or side window. You may otherwise be in the deployment area of the air
bags.
R
Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may otherwise be in the deployment area of the air
bag.
R
For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R
Always secure children under 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.

WARNING
G
Unsuitable seat covers could restrict or even
prevent the deployment of the air bags integrated into the seats. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. In addition, the function of the Occupant Classification System
(OCS) could be restricted. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have

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. 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 forward-facing 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.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instructions.

front air bag both before and during the journey.
WARNING
G
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the frontpassenger seat could then, for example, come
into contact with the vehicle's interior, especially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R
the classification of the person in the frontpassenger seat is correct and the frontpassenger front air bag is enabled or 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.
WARNING
G
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"

(
WARNING
G
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too
close to the dashboard, 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.
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 seat-belt extender to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the retracted seat-belt
extender. If necessary, adjust 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 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 ON can light up
permanently after the system self-test. This
indicates that the front-passenger front air

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

cle" (
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 safet
y reasons, Mercedes-Benz recommends that you only use seat accessories
that have been approved by Mercedes-Benz.
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy. The Occupant Classification
System (OCS) categorizes the occupant in the
front-passenger seat. Depending on that
result, the front-passenger front air bag is
either enabled or deactivated.
System self-test
DANGER
G
If 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
G
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.
WARNING
G
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.

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes
WARNING
G
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified specialist workshop as soon as possible.
WARNING
G
A deployed air bag no longer offers any protection and cannot provide the intended protection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified specialist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of 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.
WARNING
G
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer operational and are unable to perform their intended protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Tensioning Devices which have been triggered
immediately replaced at a qualified specialist
workshop.
An electric motor is used by PRE-SAFE®to
trigger the tightening of the seat belt in hazardous situations. This procedure is reversible.
If Emergency Tensioning Devices are triggered 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 ma
y 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; see "Restraint system warning

Safety
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 45).
(
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 activation threshold of the Emergency
Tensioning Devices and the air bag are determined by evaluating the rate of vehicle deceleration or acceleration which occurs at vari-
oints in the vehicle. This process is pre-
ous p
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.

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

Child restraint system on the frontpassenger seat
General notes
Accident statistics show that children
secured in the rear seats are safer than children secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install the child restraint system on a
rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to read and follow the instructions
and safety notes on the "Occupant Classification System (OCS)" (
Y page 53).
You can thus avoid the risks that could arise
as a result of:
R
an incorrectly categorized person in the
front-passenger seat
R
the unintentional deactivation of the frontpassenger front air bag
R
the unsuitable positioning of the child
restraint system, e.g. too close to the dashboard
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 45)
is the front-passenger front air bag deactivated.
Driving safety systems
67
Always observe the child restraint system
manufacturer's installation and operating
instructions.
Forward-facing child restraint system
If you secure a child in a forward-facing child
restraint system on the front-passenger seat,
always move the front-passenger 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 front-passenger seat-belt
extender to the shoulder belt guide on the
child restraint system. The shoulder belt strap
must be routed forwards from the retracted
seat-belt extender for the front-passenger
seat.
Always observe the child restraint system

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. 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 362).
In wintry driving conditions, always use winter

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
Observe the "Important safety notes" sec-
i
Y page 67).
tion (
WARNING
G
If ABS is faulty, the wheels could lock when
braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents.
Drive on carefully. Have ABS checked immediately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Y page 288) and
display messages which may be shown in the
instrument cluster (
Y page 252).
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
Observe the "Important safety notes" sec-
i

Function
BAS PLUS provides braking assistance in hazardous situations with vehicles in front within
a speed range between 4 mph (7 km/h) and
155 mph (250 km/h).
At speeds of up to approximately 44 mph
(70 km/h), BAS PLUS can react to:
R
stationary objects in the path of your vehicle, e.g. stopped or parked vehicles
R
pedestrians in the path of your vehicle
R
objects crossing your path and that are
recognized in the detection range of the
sensors

General information
COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an
autonomous braking function and adaptive
Brake Assist.
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. If you
Driving safety systems

Important safety notes
In particular, the detection of obstacles can
be 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

Important safety notes
WARNING
G
The vehicle's exhaust system may be very hot.
You could burn yourself by touching the
exhaust system if you use HANDS-FREE
ACCESS. There is a risk of injury. Always
ensure that you only make the kicking movement within the detection range of sensors.
If the SmartKey is within the rear detec-
!
tion range of KEYLESS-GO, the following
situations, for example, could lead to the
unintentional opening of the trunk:
R
using a car wash
R
using a power washer
