ning. Therefore, malfunctions can be detec-
ted in good time. The6 restraint system warning lamp in
the instrument cluster lights up when the igni- tion is switched on. It goes out no later than afew 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
GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator lamp
PASSENGER AIR BAG OFF indicator lamp :
is part of the BabySmart™ air bag deactiva-
tion system. A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front air bag is deactivated.
Depending on the person in the front-
passenger seat, the front-passenger front air
bag must either be deactivated or enabled;
see the following points. You must make sure
of this both before and during a journey.
R Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the
installed child restraint system, and the age and size of the child. Therefore, always
observe the information on "Children in the
vehicle" ( Ypage 55). There you will also
find instructions on rearward and forward-
facing child restraint systems on the front-
passenger seat.
R All other persons: the PASSENGER AIR
BAG OFF indicator lamp must be off. Be
sure to observe the notes on "Seat
belts“ ( Ypage 43) and "Air bags"
( Y page 48). There you can also find infor-
mation on the correct seat position.
Observe the information on the BabySmart™
air bag deactivation system in the front-
passenger seat ( Ypage 59).
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi- cle 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 posi- tion in relation to the air bag.

immediately replaced at a qualified specialistworkshop.
If Emergency Tensioning Devices are trig-
gered or air bags are deployed, you will hear a bang, and a small amount of powder may also
be released. The 6restraint system warn-
ing lamp lights up.
Only in rare cases will the bang affect your
hearing. The powder that is released gener-
ally does not constitute a health hazard, but it
may cause short-term breathing difficulties in
people with asthma or other respiratory prob-
lems. 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 Tension-
ing Devices (ETDs) contain perchlorate mate- rial, which may require special handling and
regard for the environment. National guide-
lines 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 impor-
tant physical data relating to vehicle deceler- ation 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 fron- tal 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 lamp" ( Ypage 42)
R the belt tongue is engaged in the buckle on
the respective front-passenger seat The Emergency Tensioning Devices in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
R Driver's air bag
R Front-passenger front air bag
The front-passenger front air bag is activated or deactivated depending on the person on
the front-passenger seat. The front-
passenger front air bag can only deploy in an
accident if the PASSENGER AIR BAG OFF indi- cator lamp is off. Observe the information on
the PASSENGER AIR BAG OFF indicator lamp ( Y page 43).
Your vehicle has a two-stage driver's air bag.
During the first deployment stage the driver's air bag fills with sufficient 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 thresh- old is reached within a few milliseconds.
The activation threshold of the Emergency
Tensioning Devices and the air bag are deter- mined by evaluating the rate of vehicle decel-
eration or acceleration which occurs at vari-
ous points in the vehicle. This process is pre-
emptive in nature. Deployment should take
place in good time at the start of the collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen- tially determined by:
R the distribution of forces during the colli-sion
R the collision angle
R the deformation characteristics of the vehi-
cle
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.

passenger seat accordingly. Always observe
the information about suitable positioning of
the child restraint system in this Operator's
Manual as well as the child restraint system
manufacturer's installation instructions.
PASSENGER AIR BAG OFF indicator lamp:
shows you whether the front-passenger front air bag is deactivated.
X Turn the SmartKey to position 1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp: R is lit : the front-passenger front air bag is
deactivated. It will then not be deployed in
the event of an accident.
R is not lit , the sensor system did not detect
a child restraint system with transponder
for the BabySmart™ air bag deactivation
system. If, in the event of an accident, all
deployment criteria are met, the front-
passenger front air bag is deployed.
GWARNING
Electronic devices on the front-passenger
seat can affect the function of the Baby-
Smart™ air bag deactivation system, forexample:
R Laptop
R Mobile phone
R Transponder cards such as ski passes or
access passes
The front-passenger air bag could deploy acci-
dentally or not function as intended during an accident. This poses an increased risk of
injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of thefront-passenger front air bag both before andduring the journey.
Child restraint system on the front-
passenger seat
General notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren 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 information on the "Baby- Smart™ air bag deactivation system"( Y page 59).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the BabySmart™ air bag deactivation
system sensor system
R the unintentional deactivation of the front-
passenger front air bag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board

62Children in the vehicle
Safety

GWARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the vehi-cle, even if they are secured in a child restraint
system, or with access to an unlocked vehicle. A child's unsupervised access to a vehicle
could result in an accident and/or serious
personal injury. The children could: R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on theseparts.
Child-proof locks for the rear doors
GWARNING
Children could open a rear door from inside
the vehicle. This could result in serious inju-
ries or an accident. Therefore, when children
ride in the rear always secure the rear doors
with the child-proof locks.
You secure each door individually with the
child-proof locks on the rear doors. A door
secured with a child-proof lock cannot be
opened from inside the vehicle. When the
vehicle is unlocked, the door can be opened
from the outside.
X To activate: press the child-proof lock

ABS (Anti-lock Braking System)
Important safety notes
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If the ABS malfunctions, other driving systems
such as the BAS or the ESP ®
are also switched
off. Observe indicator and warning lamps that may come on as well as messages in the mul-
tifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi- cle when braking.
Provided that the differential locks are not
active, ABS works from a speed of about
5 mph (8 km/h) upwards, regardless of road-surface conditions. ABS works on slippery
surfaces, even if you only brake gently.
The yellow !ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is running.
Braking
If ABS intervenes when braking, you will feel apulsing in the brake pedal. X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
Off-road ABS
If the LOW RANGE shift range is selected by
the transfer case, ( Ypage 132), an ABS sys-
tem specifically suited to off-road terrain is
automatically activated.
At speeds below 37 mph (60 km/h), the front wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces
the stopping distance on off-road terrain. This limits steering capability.
BAS (Brake Assist System)
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
Driving safety systems65
Safety
Z

Adaptive brake lights
If you brake sharply from a speed of more
than 30 mph (50 km/h) or if braking is assis-ted by BAS, the brake lamps flash rapidly. In
this way, traffic traveling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 45 mph (70 km/h)to a standstill, the
hazard warning lamps are activated automat-
ically. If the brakes are applied again, the
brake lamps light up continuously. The hazard
warning lamps are deactivated automatically if you drive faster than 6 mph (10 km/h). You
can also switch off the hazard warning lamps using the hazard warning button( Y page 90).
ESP®(Electronic Stability Program)
Important safety notes
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further driv- ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
!Only operate the vehicle for a maximum of
ten seconds on a brake test dynamometer.
Switch off the ignition.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
!A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system. ESP
®
monitors the driving stability and the
traction. Traction is the power transmission
between the tires and the road surface. ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps ( Y page 165) and display messages which
may be displayed in the instrument cluster( Y page 148).
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilize the vehi-
cle during braking.
If ESP ®
intervenes, the ÷warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X Only depress the accelerator pedal as far as
necessary when pulling away.
X Adapt your driving style to suit the prevail-
ing road and weather conditions.
iOnly use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
iIf differential locks are switched on, ABS,
BAS and ESP ®
switch off automatically.
4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
Traction control remains active, even if you
deactivate ESP ®
.
66Driving safety systems
Safety

iIf ESP®
is deactivated, it is reactivated
automatically if you are driving at above
37 mph (60 km/h) (on AMG vehicles above
62 mph (100 km/h)) or you exceed a cer-
tain lateral acceleration.
Trailer stabilization
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP ®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail- ing road and weather conditions.
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until the vehicle/trailer combination has stabi- lized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h).
EBD (electronic brake force distribu- tion)
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps ( Ypage 163) as well as dis-
play messages ( Ypage 148).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
ADAPTIVE BRAKE
ADAPTIVE BRAKE provides increased braking
safety. In addition to the braking function,
ADAPTIVE BRAKE also has the HOLD function
( Y page 126) and hill start assist
( Y page 105).
