Never tamper with electronic components
and their software.
SRS (Supplemental Restraint System)
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
forces to which occupants are subjected dur-
ing an accident.
SRS consists of:
R the 0081 SRS warning lamp
R belt tensioners
R belt force limiters
R airbags
The 0081
0081 SRS warning lamp The SRS functions are checked regularly
when you turn on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 0081 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
deployed in the event of an accident with
heavy braking.
Am alfunction has occurred if the 0081SRS
warning lamp:
R does not light up when you switch on the
ignition
R does not go out after the engine has been
running for afew seconds
R lights up again once the engine is running
In this case, have SRS checked immediately
at aq ualifieds pecialist workshop. Triggering of belt tensioners, belt force
limiters and airbags In the event of
acollision, the airbagc ontrol
unit evaluates important physical data such
as duration, direction and force of the vehicle
deceleration or acceleration. Based on the
evaluation of this data and in the event of lon-
gitudinal deceleration, in acollision, and
depending on the rate of deceleration, the
airbagc ontrol unit pre-emptively triggers the
belt tensioners in the first stage.
i The belt tensioners can only be triggered
if the belt tongue is correctly engaged in the
seat belt buckle.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
al ongitudinal direction.
Your vehicle has adaptive, duals tage front
airbags. When the first activation threshold is
reached, the front airbagisf illedwith enough
propellant gas to reduce the risk of injuries.
The front airbagiso nly fullydeployed if asec-
ond threshold is reached within afew milli-
seconds, due to the control unit having detec-
ted further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of acollision, the airbagc on-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration, in
order to determine whether it is necessary to
trigger abelt tensioner or an airbag.
The belt tensioner and airbagt riggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airbag
must be deployed during –and not at the end
of –t he collision.
i Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbagd eployment must take place during
the impact and must be adapted to provide Occupant safety

BASP LUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic.
BASP LUS may not detec tnarro wvehicles
such as motorcycles and vehicles driving on
ad ifferen tline.
Following acollision or crash-related damage
to the fron tend of the vehicle, have the con-
figuration and operation of the radar sensors
checked at aMercedes-Benz Service Centre.
If BASP LUS is not available due to amalfunc-
tion in the radar sensor system, the braking
system remains available with full brake
boostin geffec tand BAS. Adaptive brake lamps
i Adaptiv ebrake lamps are only available in
certain countries.
If you brake sharply from aspeed of more
than 50 km/ horifb raking is assisted by BAS
or BAS PLUS* ,the brake lamp sflashr apidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspee dofm ore
than 70 km/h to astandstill, the hazard warn-
ing lamp sare activated automatically.Ift he
brakes are applieda gain, the brake lamps
light up continuously.T he hazard warning
lamp sswitch off automatically if you travel
faster than 10 km/h .You can alsos witch off
the hazard warning lamp susing the hazard
warning switch button (Y page84). ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
If ESP ®
detects that the vehicl eisdeviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary ,the engine outpu tisalso
modified to keep the vehicl eonthe desired
course withi nphysical limits. ESP ®
assists
the drive rwhen pulling away on wet or slip-
pery roads. ESP ®
can alsos tabilise the vehi-
cle during braking.
When ESP ®
intervenes, the 00C6warning
lamp flashes in the instrument cluster. G
Risk of accident
If the 00C6 warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator peda lasfar as
necessary when pulling away.
R adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
Otherwise, the vehicl ecoulds kid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot overrid ethe
lawsofp hysics.
! If the vehicl eistobetowed with the front
or rear axle raised, the ignitio nmust be
switched off (key in position 0or 1in the
ignitio nlock). Application of the brakes by
ESP ®
coul dotherwise destroy the brake
system on the front or rear axle.

Depending on driving style, the vehicle con-
sumes up to 0.8 loil per 1,000 km. The oil
consumption may be highert han this when

met:

ground.
R the engine shouldbes witched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine shouldbes witched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).

the minimum mark 008Aand maximum
mark 0047.
X Top up the oil if necessary.
Topping up the engine oil H
Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwis ebe
damaging the environment. Cap (example)
X Turn cap 0046anti-clockwise and remove.
X Top up with the amount of oil required

In Germany, th emaximum permissible speed

For certain Mercedes-Ben zvehicles, th emax-

when towing atrailer. Refer to th e"Technical
