The restraint system consists of:
R
seat belts
R child restraint systems
R LATCH-type (ISOFIX) child seat anchors
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R NECK-PRO head restraints
R Air bag system components with:
-The 00730074 indicator lamp
- Front-passenger seat with BabySmart™
air bag deactivation system
The different air bag systems work
independently of each other. The protective
functions of the system work in conjunction
with each other. Not all air bags are always
deployed in an accident.
i Observe the additional information on
infants and children traveling with you in
the vehicle and restraint systems for
infants and children (Y page 54). SRS (Supplemental Restraint System)
Introduction SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
R
The 0075 SRS warning lamp
R Air bags
R Air bag control unit (with crash sensors)
R Emergency Tensioning Device (ETD) for
seat belts
R Seat belt force limiter SRS warning lamp G
WARNING
The SRS self-check has detected a
malfunction if the 0075 SRS indicator lamp:
R does not light up at all
R does not go out after approximately four
seconds after the engine is started
R lights up after
the
engine is started or while
the vehicle is in motion
For your safety, Mercedes-Benz strongly
recommends that you have the system
checked as soon as possible at a qualified
specialist workshop. SRS may otherwise fail
to activate when it is needed in the event of
an accident, which could lead to serious or
fatal injuries. SRS might also be activated
unexpectedly and unnecessarily, which could
also result in injury.
In addition, work carried out improperly on
SRS may render SRS inoperative or cause
unintended air bag deployment. Work on the
SRS system should only be carried out by
qualified specialist personnel. Consult a
qualified specialist workshop.
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).
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 0075 SRS 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 engine is started.
The SRS components are in operational
readiness when the SRS 0075 indicator lamp
goes out while the engine is running. Occupant safety

Safety Z

If the
0073007C indicator lamp does not go
out, please consult an authorized Mercedes-
Benz Center. Driver's air bag
0043 deploys in front of the
steering wheel; front-passenger front air
bag 0044 deploys in front
of and above the glove
box.
The front air bags increase protection for the
driver's and front-passenger's head, neck and
chest.
They are deployed:
R in the event of certain frontal impacts
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R independently of other air bags in the
vehicle
R depending on whether the seat belt is being
used
If the vehicle rolls over, the front air bags are
generally not deployed. If the system detects
high vehicle deceleration in a longitudinal
direction, the front air bags are deployed.
Your vehicle is equipped with a dual-stage
driver's air bag and a single-stage front-
passenger front air bag. In the event of a
collision, the air bag control unit evaluates the
vehicle deceleration. In the first deployment
stage, the driver's air bag is filled with enough
propellant gas to reduce the risk of injuries.
The front-passenger front air bag, however, is
immediately filled with the maximum amount
of propellant gas. The driver's air bag is fully deployed if a second deployment threshold is
exceeded within a few milliseconds.
The
lighter the
front

passenger, the higher the
vehicle deceleration rate required (predicted
at the start of the impact) for triggering the
front-passenger front air bag.
The front air bags will not deploy in impacts
with vehicle deceleration or acceleration
rates which do not exceed the system’s
preset deployment thresholds for vehicle
deceleration or acceleration. You will then be
protected by the fastened seat belt.
Front-passenger front air bag 0044 will only
deploy if:
R the front-passenger seat is occupied.
R the 00730074 indicator lamp on the center
console is not lit (Y page 44)
R the impact exceeds a preset deployment
threshold
The front-passenger air bag is automatically
activated and deactivated. Both driver and
passenger should always check whether the
front-passenger air bag is activated or
deactivated.
The deployment of the driver's air bag does
not mean that the front-passenger air bag will
also deploy. If the system recognizes that the
front-passenger seat is empty, the front-
passenger air bag does not deploy even if the
impact fulfills the criteria and the driver's air
bag has deployed.
If the system detects that the front-passenger
seat is occupied, the 00730074 indicator
lamp lights up for approximately six seconds
if:
R you turn the SmartKey to position 1 or 2 in
the ignition lock.
R the engine is running and then you switch
it off.
This indicates the operational readiness of
the front-passenger air bag.
Note that objects placed on the front-
passenger seat may cause the system to
recognize the seat as occupied. This can
result in the deployment of the front- Occupant safety

Safety Z

ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Important safety notes"
section ( Y page 60). G
WARNING
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
multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance. G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There
is

an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
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.
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 0025 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
a pulsing in the brake pedal. 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.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving.
Off-road ABS If the
LOW RANGE shift range is
selected by
the transfer case, (Y page 199), an ABS
system 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
digging-in effect achieved in the process
reduces the stopping distance on off-road
terrain. This limits steering capability. BAS (Brake Assist System)
i Observe the "Important safety notes"
section ( Y page 60). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking
situations. 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 systems
61
Safety Z

Adaptive brake lamps
If you brake sharply from a speed of more
than 30 mph (50 km/h) or if braking is
assisted 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
automatically. If
the brakes are applied again,
the brake lamps light up continuously. If you
drive faster than 6 mph (10 km/h), the hazard
warning lamps are deactivated automatically.
You can also switch off the hazard warning
lamps using the hazard warning button
(Y page 104). ESP
®
(Electronic Stability Program)
Important safety notes i
Observe the "Important safety notes"
section ( Y page 60).G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk
of

skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! 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
otherwise destroy the brake system.
! A function or performance test should
only be carried out on a two-axle
dynamometer. 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 driving stability and traction.
Traction is the power transmission between
the tires and the road surface.
ESP ®
is deactivated if

the 00BB warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the 00E5 warning lamp and the 00BB
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 252) and any display messages that
appear in the instrument cluster
(Y page 226).
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
slippery roads. ESP ®
can also stabilize the
vehicle during braking.
If ESP ®
intervenes, the 00E5 warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.
X Adapt your driving style to suit the
prevailing road and weather conditions.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
i If differential locks are

switched on, ABS,
BAS and ESP ®
switch themselves off
automatically.

WARNING
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 unsupervised in the
vehicle, even if they are secured in a child
restraint system, and do
not give them access
to an unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. They could:
R injure themselves on vehicle parts
R be seriously or fatally injured by extreme
heat or cold
R injure themselves or have an accident with
vehicle equipment that may still be in
operation even after the SmartKey has
been removed from the ignition, such as the
seat adjustment, steering wheel
adjustment or memory function.
If children open a door, they could cause
severe or even fatal injury to other persons; if
they get out of the vehicle, they could injure themselves when doing so or be seriously or
even fatally injured by any passing 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 a child could be burned on these
parts.
G
WARNING
Do not carry heavy or hard objects in the
passenger compartment or cargo
compartment unless they are firmly secured
in place.
Unsecured or improperly positioned cargo
increases a child's risk of injury in the event

Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs carry a high voltage. You could
get an electric shock

and be seriously or even
fatally injured if you touch the electric
contacts on Xenon bulbs. Therefore, never
remove the cover from Xenon bulbs.
Do not change the Xenon bulbs yourself, but
have them replaced at a qualified workshop.
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
LED lamps You can neither replace Xenon bulbs nor LED
bulbs. Have LED
bulbs

changed at a qualified
specialist workshop. 108
