Mercedes-Benz GenuineParts or parts of equal
qu ality. Only use tires, wheels and accessory
parts that ha vebeen specifically appr ovedfo r

Mercedes-Benz GenuineParts are subject to
st rict quality control. Each part has been spe‐
cially de veloped, manufactured or selecte dfo r
Mercedes-Benz vehicles and fine-tuned forth em.
Therefore, only Mercedes-Benz GenuineParts
should be used.
More than 300,000 dif fere nt Mercedes-Benz

Restra int sy stem functionality
When the ignition is switched on, a sy stem self-
te st is per form ed, during which the6
re stra int sy stem warning lamp lights up. It goes
out no later than a few seconds af terth eve hicle
is star ted. The components of there stra int sys‐
te m are then functional.
Re stra int sy stem malfunction
RThe 6 restra int sy stem warning lamp
does not light up when the ignition is
switched on.
RThe 6 restra int sy stem warning lamp
lights up continuously or repeatedly during a

WARNING Risk of injury orfata l injury
due toa malfunction in there stra int sys‐
te m
If th ere stra int sy stem is malfunctioning,
re stra int sy stem components may be trig‐
ge red unintentionally or might not be trig‐
ge red at all in theev ent of an accident. This
may af fect the Emer gency Tensioning Device
or airbag, forex ample.
#Ha ve there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop.
Fu nction of there stra int sy stem in an acci‐
dent
How there stra int sy stem works is de term ined by
th e se verity of the impact de tected and the type
of accident anticipated:
RFr ontal impact
RRe ar impact
RSide impact
RRo llover
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on
th eev aluation of the sensor values measured at
va rious points in theve hicle. This process is pre-
em ptive in nature. The triggering/deployment of
th e components of there stra int sy stem should ta
ke place in good time at thest art of the colli‐
sion.
Fa ctors whi chcan only be seen and measure d
af te r a collision has occur red cann otplay a deci‐
sive role in airbag deployment, nor do they pro‐
vide an indication of airbag deployment.
The vehicle may be deformed significantly with‐
out an airbag being deplo yed. This is the case if
only parts which are relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an airbag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts
such as longitudinal members are hit, forex am‐
ple, theve hicle deceleration may be high enough
fo rth is to happen.

Objects intheve hicle interior may restrict cor‐
re ct functioning of an air bag. There fore alw ays
ensure that:
RThere are no other persons, animals or
objects between theve hicle occupants and
an air bag.
RThere are no objects between the seat, door
and door pillar (B-pillar).
RThere are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks.
RDo not fix any accessory parts, such as cup
holders, inside the deployment area of an air
bag, e.g. on doors, side windo wsor side pan‐
eling.
RThere are no heavy, sharp-edged or fragile
objects in the poc kets of your clo thing. Store
such objects in a suitable place.

WARNING Risk of injury from modifica‐
tions tothe airbag co ver
If yo u modify an airbag co ver or af fix objects
such assticke rs to it,the airbag can no lon‐
ge r function cor rectl y.
#Ne ver modify an airbag co ver and do
not af fix objects toit.
The ins tallation location of an air bag can be
identified bythe designation AIRB AG.
&
WARNING Risk of injury or death dueto
th e use of unsuitable seat co vers
Uns uitable seat co vers can obstruct or pre‐
ve nt the deployment of air bags integrated
into the seats.
Consequentl y,the air bags cannot protect
ve hicle occupants as they are designed to
do. In addition, operation of the automatic
front passenger air bag shutoff may be
re stricted.
#Yo u should only use seat covers that
ha ve been appr oved forth e cor respond‐
ing seats byMercedes-Benz.
&
WARNING Risk of injury duetomalfunc‐
tions of the sensors in the door paneling
Sensors tocontrol the airbags are located in
th e doors. Modifications or worknot per‐
fo rm ed cor rectly tothe doors or door panel‐
ing, as well as damaged doors, can lead to
th e function of the sensors being impaired.
The airbags might therefore not function
proper lyany more.

Driving and driving saf ety sy stems
Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist you in drivin g, parking and maneu‐
ve ring theve hicle. The driving sy stems are aids
and do not relie ve you of your responsibility. Pay
attention tothe tra ffic conditions at all times
and inter vene when necessary . Beaware of the
limitations rega rding the safe use of these sys‐
te ms.
Fu nction of thera dar senso rs
Some driving and driving safe ty systems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle&#39;s equipment).
Depending on theve hicle&#39;s equipment, thera dar
sensors are integrated behind the bumpers
and/or behind thera diator grille. Keep these
parts free of dirt, ice and slush (

Fu nctions of ABS (anti-lock braking sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, the wheels are pr evented
from blocking, e.g. due tomaximum full-s top
braking or insuf ficient traction of the tires.
RVe hicle steerability while braking is ensured.
If ABS inter venes when braking, youwill feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving.
Sy stem limitations
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a
