Index

Do not attempt to modify the wiring as well as
electronic components or their software.
Always have work on electrical and electronic
components carried out at a qualified special- ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too quickly over an obstacle, e.g.
a kerb, slowing thresholds or a pothole in
the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, underbody,
chassis parts, wheels or tyres could be dam-
aged without the damage being visible. Com- ponents damaged in this way can unexpect-
edly fail or, in the case of an accident, no lon-
ger withstand the strain they are designed to withstand.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come into 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 spe-
cialist workshop. If, on continuing your jour-
ney, you notice that driving safety is impaired,
stop the vehicle immediately, paying atten-
tion to road and traffic conditions. In such
cases, consult a qualified specialist work-
shop. Declarations of conformity

Mercedes-Benz recommends that you use only
driving aids that have been approved specifi-
cally for your vehicle by Mercedes-Benz. 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 on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec- onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
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 G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This may affect
the seat belt tensioner or airbag, for example. This poses an increased risk of injury or even
fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator
lamp shows the status of the front-passenger
front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off.
Depending on the person in the front-passenger seat, the front-passenger front airbag must be
either disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a rearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper-
ative to observe the notes on the "Automatic front-passenger front airbag deactivation sys-
tem" (Y page 50) and on "Children in the
vehicle" (Y page 59).
R Children in a forward-facing child
restraint system: depending on the installed
child restraint system and the age and size of the child, the front-passenger front airbag is
either disabled or enabled. Therefore, it is
imperative to observe the notes on the "Auto-
matic front-passenger front airbag deactiva- Occupant safety

R STEER CONTROL (Y page 78) Important safety notes
The driving safety systems can neither reduce
the risk of an accident if you fail to adapt your
driving style or are not paying attention nor
override the laws of physics. Driving safety sys-
tems 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 pre-
vailing road and weather conditions and main-
tain a safe distance from the vehicle in front.
Drive carefully.
The driving safety systems described work as
effectively as possible only when there is ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa-
tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 342).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively 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 on 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 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you
brake only gently. Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 67). G
WARNING
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.
If ABS is malfunctioning, other systems, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 275) and display mes-
sages that may be shown on the instrument
cluster (Y page 242).
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation 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; this serves as a
reminder to take extra care while driving. BAS (Brake Assist System)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.

tion (Y page 67). Driving safety systems
