Protection of the environment
General notes
Environmental note
H
Daimler's declared policy is one of comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
R
operating conditions of your vehicle
R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R
avoid short trips as these increase fuel consumption.
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
R
remove roof racks once you no longer need
them.
R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R
always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R
do not depress the accelerator pedal when
starting the engine.
R
do not warm up the engine when the vehicle
is stationary.
R
drive carefully and maintain a safe distance
from the vehicle in front.
R
avoid frequent, sudden acceleration and
braking.
R
change gear in good time and use each gear
only up to Ô of its maximum engine speed.
R
switch off the engine in stationary traffic.
R
keep an eye on the vehicle's fuel consumption.
Environmental concerns and recommendations
Wherever the operating instructions require
you to dispose of materials, first try to regenerate or re-use them. Observe the relevant
environmental rules and regulations when
disposing of materials. In this way you will
help to protect the environment.
Genuine Mercedes-Benz parts
Environmental note
H
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
Air bags and Emergency Tensioning Devi-
!
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R
doors
R
door pillars
R
door sills
R
seats
R
cockpit
R
instrument cluster
R
center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
Page 25
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 MercedesBenz. 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 408).

Sports Utility Vehicle
WARNING
G
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road
conditions. There is a risk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the
prevailing road and weather conditions.
Utility vehicles have a significantly higher rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle,
and severe or fatal injury.
In a rollover crash, an unbelted person is significantly more likely to die than a person
wearing a seat belt.
You and all vehicle occupants should always
wear your seat belts.
Operating safety
Important safety notes
WARNING
G
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/maintenance work as well as any required repairs
carried out at a qualified specialist workshop.
WARNING
G
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 net-
Z
Page 28
Introduction
26
worked 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
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 immediat
ely, 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, mal-
functions, 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
Page 31
Introduction
29
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.

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 45)
(
R
have adjusted their seat and head restraint
properly (
Y page 109).
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 .
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 Devices and air bags"
Y page 57).

See "Children in the vehicle" for information
on infants and children traveling with you in
the vehicle restraint systems for infants and
children (

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).
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.

Depending on the person in the frontpassenger seat, the front-passenger front air
bag must either be deactivated or enabled;
see the following points. You must make sure
of this both before and during a journey.
R
Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the
Safety
installed child restraint system, and the age
and size of the child. Therefore, be sure to
observe the notes on the "Occupant Classification System (OCS)" (
on "Children in the vehicle" (
Y page 51) and
Y page 60).
There you will also find instructions on rearward and forward-facing child restraint systems on the front-passenger seat.
R
All other persons: depending on the classification of the person in the frontpassenger seat, the front-passenger front
air bag is enabled or deactivated
Y page 51). Be sure to observe the notes
(
on "Seat belts“ (
Y page 48). There you can also find infor-
(
Y page 44) and "Air bags"
mation 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, the seat belt force limiters
reduce the force exerted by the seat b
elt 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.
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 direc-
Page 47
tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seat
belt.
WARNING
G
The seat belt does not offer the intended level
of protection if you have not moved the backrest to an almost vertical position. When braking or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
WARNING
G
Persons under 5 ft (1.50 m) in height cannot
fasten the seat belt correctly without an additional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable restraint
systems.

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.

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.
Also ensure that there are never objects
between a person and the seat, e.g. cushions.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe
the "Loading guidelines" for securing objects,
luggage or loads (

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 57).
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.
Page 51
Occupant safety
49
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.
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 .
R
Always observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (
in the vehicle" (
Y page 51) and on "Children
Y page 60) in addition to
the child restraint system manufacturer's
installation instructions.
Objects in the vehicle interior may prevent an air bag from functioning correctly.
Before starting your journey and to avoid risks
resulting from the speed of the air bag as it
deploys, make sure that:
R
there are no people, animals or objects
between the vehicle occupants and an air
bag.
R
there are no objects between the seat, door
and B-pillar.
R
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 suitabl
WARNING
G
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
WARNING
G
Sensors to control the air bags are located in
the doors. Modifications or work not performed correctly to the doors or door paneling, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door paneling carried out at a qualified specialist workshop.

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.
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

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the frontpassenger front air bag is either enabled or
deactivated.
The system does not disable:
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. 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 back-

Press the Start/Stop button once or twice,
or turn the SmartKey to position 1 or 2 in
the ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
must light up simultaneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.

PASSENGER AIR BAG ON lights up: the
front-passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front-passenger front
air bag is deployed.
R
PASSENGER AIR BAG OFF lights up: the
front-passenger front air bag is deactivated. It will then not be deployed in the event
of an accident.
If the status of the front-passenger front air
bag changes while the vehicle is in motion, an
air bag display message appears in the instrument cluster (
Y page 271). When the front-
passenger seat is occupied, always pay attention to the PASSENGER AIR BAG ON and
PASSENGER AIR BAG OFF indicator lamps. Be
aware of the status of the front-passenger
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.
Page 55
Occupant safety

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 belt sash guide to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the vehicle belt sash
guide. If necessary, adjust the vehicle belt
sash guide and the front-passenger seat
accordingly. Always observe the child
restraint system manufacturer's installation
instructions.
If OCS determines that:
R
the front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the frontpassenger front air bag is deactivated.
R
the front-passenger seat is occupied by a
child of up to twelve months old, in a standard child restraint system, the PASSENGER
AIR BAG OFF indicator lamp lights up after
the system self-test and remains lit. This
indicates that the front-passenger front air
bag is deactivated.
But even in the case of a twelve-month-old
child, in a standard child restraint system,
the PASSENGER AIR BAG 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 child restraint system on a suitable rear seat.
R
the front-passenger seat is occupied by a
person of smaller stature (e.g. a teenager
or small adult), 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 adult stature, the
PASSENGER AIR BAG ON indicator lamp
lights up after the system self-test and
remains lit. This indicates that the frontpassenger front air bag is activated.
If children are traveling in the vehicle, be sure
to observe the notes on "Children in the vehi-

an authorized Mercedes-Benz Center. The
front-passenger seat should only be repaired
Safety
at an authorized Mercedes-Benz Center.
If the front-passenger seat, the seat cover or
the seat cushion is damaged, have the necessary repair work carried out at an authorized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recommends that you only use seat accessories
that have been approved by Mercedes-Benz.
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy. The Occupant Classification
System (OCS) categorizes the occupant in the
front-passenger seat. Depending on that
result, the front-passenger front air bag is
either enabled or deactivated.
System self-test
DANGER
G
If 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

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

(
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 various points in the vehicle. This proce
ss 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 control unit of the restraint s
ystem
detects a side impact or a vehicle rollover, the
relevant components of the restraint system
are activated separately depending on the
anticipated type of accident.

Children in the vehicle
Important safety notes
Accident statistics show that children
secured in the rear seats are safer than children secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
R
always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles. The child restraint system must be
appropriate to the age, weight and size of
the child
R
be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
R
be sure to observe the instructions and
safety notes on the "Occupant Classification System (OCS)" (
WARNING
G
Y page 51)
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.
Page 63
Children in the vehicle
61
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.
WARNING
G
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
WARNING
G
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Children may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Protect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting properly. Particular attention must be
paid to children.
Observe the safety notes on the seat belt
(Y page 44) and the notes on correct use of
seat belts (
Y page 45).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
41 lbs (18 kg) until they reach a height where
a three-point seat belt can be properly fastened without a booster seat.
Special seat belt retractor
WARNING
G
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retractor is disabled and the inertia real draws in a
portion of the seat belt. The seat belt cannot
be immediately refastened. There is an
increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying attention to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts in the vehicle, except the driver's seat belt, are equipped with a special seat
belt retractor. When activated, the special
seat belt retractor ensures that the seat belt
cannot slacken once the child seat is secured.

LATCH-type (ISOFIX) child seat securing system
WARNING
G
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt
integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.

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,
always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (
Y page 51).

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. Fully
retract the seat cushion length. 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 lie as flat as possible
against the backrest of the front-passenger
seat. The child restraint system must not
touch the roof or be subjected to a load by the
head restraint. Adjust the angle of the seat
backrest and the head restraint position
accordingly. Always make sure that the shoulder belt strap is correctly routed from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system. The shoulder
belt strap must be routed forwards and downwards from the vehicle belt outlet. If necessary, adjust the vehicle belt outlet and the
front-passenger seat accordingly.

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 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.
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 374).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as
effectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehicle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even
when you only brake gently.
Important safety notes
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 294) and
display messages which may be shown in the
instrument cluster (
Y page 258).

BAS PLUS (Brake Assist System
PLUS) with Cross-Traffic Assist
General information
BAS PLUS can help you to minimize the risk of
a collision with a vehicle or a pedestrian and
reduce the effects of such a collision. If BAS
PLUS detects a danger of collision, you are
assisted when braking.
Pay attention to the important safety
i
notes in the "Driving safety systems" sec-
Y page 67).
tion (
BAS PLUS is only available on vehicles with
the Driving Assistance package.
For BAS PLUS to assist you when driving, the
radar sensor system and the camera system
must be operational.
With the help of a sensor system and a camera system, BAS PLUS can detect obstacles:
R
that are in the path of your vehicle for an
extended period of time
R
that cross the path of your vehicle
In addition, pedestrians in the path of your
vehicle can be detected.
BAS PLUS detects pedestrians by using typical characteristics such as the body contours
and posture of a person standing upright.
If the radar sensor system or the camera system is malfunctioning, BAS PLUS functions
are restricted or no longer available. The
brake system is still available with complete
brake boosting effect and BAS.

tion (
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
do not react to the visual and audible collision
warning, autonomous braking can be initiated
in critical situations. If you apply the brake
yourself in a critical situation, the COLLISION
PREVENTION ASSIST PLUS adaptive Brake
Assist assists you.
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
example in parking garages
R

Adaptive Brake Assist
General information
Observe the "Important safety notes" sec-
i
Y page 67).
tion (
With the help of adaptive Brake Assist, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
If adaptive Brake Assist detects a risk of collision with the vehicle in front, it calculates
the braking force necessary to avoid a collision. If you apply the brakes forcefully, adaptive Brake Assist will automatically increase
the braking force to a level suitable for the
traffic conditions.
Adaptive Brake Assist provides braking assistance in hazardous situations at speeds
above 4 mph (7 km/h). It uses radar sensor
technology to assess the traffic situation.
Up to a speed of approximately 155 mph
(250 km/h), adaptive Brake Assist is capable
of reacting to moving objects that have
already been detected as such at least once
over the period of observation.
Up to a speed of approximately 44 mph
(70 km/h), adaptive Brake Assist reacts to
stationary obstacles.

HANDS-FREE ACCESS
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 tailgate:
R
using a car wash
R
using a power washer
Make sure that the SmartKey is at least 3 m
away from the vehicle.
General notes
With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the tailgate or
stop the procedure without using your hands.

this, make a kicking movement under the
bumper with your foot.
Observe the following points:
R
Carry your KEYLESS-GO key about your
person. The KEYLESS-GO key must be in
the rear detection range of the vehicle.
R
When making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clearance to the rear of the vehicle. You could
otherwise lose your balance, e.g. on ice.
R
Always ensure that you only make the kicking movement within the detection range of
sensors :.
R
Stand at least 12 in (30 cm) away from the
rear area while doing so.
R
Do not come into contact with the bumper
while making the kicking movement. Otherwise, the sensors may not function correctly.
R
HANDS-FREE ACCESS does not function
when the engine is started.
R
If a KEYLESS-GO key is within the rear
detection range of KEYLESS-GO, HANDSFREE ACCESS could be triggered. The tail-
gate could thus be opened or closed unintentionally, for example, if you:
