.Never carry out any
modifications on the restraint systems.
Never tamper with electronic components
and their software. SRS (Supplemental Restraint System)
Introd uction SRS reduces the risk of occupants coming
into contact with the vehicle's interio
rinthe
even tofana ccident. It can als oreduce the
effect of the forces to which occupant sare
subjected during an accident.
SRS consists of:
R 6 SRS warning lamp
R airbags
R airbag con trol unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS warning lamp SRS func
tions ar echecked regularly when
you switc honthe ignition and when the
engin eisrunning. Therefore, malfunctions
can be detected in good time.
The 6 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 star ted. G
Risk of inju
ry
If SR Sism alfunctioning, individual systems
may be activated unintentionally or may not
be triggered in the event of an accident with
ah igh rate of vehicle deceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up after the ignition is switched on.
R the engine is runnin gand the 6SRS
warning lamp doe snot go out after afew
seconds.
R the engine is runnin gand the 6SRS
warning lamp lights up again. In this case, have SRS checked immediately
at
aq ualified specialist workshop .Mercedes-
Benz recommends that you use aMercedes-
Benz Servic eCentr efor this purpose.
In particular ,work relevant to safet yoron
safety-related systems must be carried out at
aq ualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags In the event of
acollision ,the airbag con trol
unit evaluates important physical data relat-
ing to the vehicle deceleration or acceleration
during the first stage of the collision, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data ,the air-
bag con trol unit pre-emptivel ytriggers the
belt tensioners in th efirst stage.
i The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
The front airbags are also deployed if there is
an even higher rate of vehicle deceleration in
al ongitudinal direction.
Your vehicle has adaptive, dual-stage front
airbags. In the even tofacollision, the airbag
control unit evalu atesthe vehicle decelera-
tion. Whe nthe first deploymen tthreshol dis
reached, th efront airbag is fille dwith enough
gas to reduce the risk of injuries. The front
airbag is fully deployed if asecon ddeploy-
men tthreshold is exceeded withi nafew mil-
liseconds.
Th eb elt tensioner and airbag triggering
thresholds are variable and are adapted to the
rat eofd eceleration of the vehicle. This proc-
ess is pre-emptiv einnature. The triggering
process must take place in good time at the
start of the collision.
i Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other. Occupant safety

Deactivating/activating ESP ®ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilis ethe vehicle
if the vehicle star tsto skid or awheel star ts
to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinnin gof
the wheels results in acutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the äwarning lamp in the
instrument cluster flashes .Insuch situations,
ESP ®
will not stabilise the vehicle.

Risk of accident
If the å warning lamp in the instrument

trailer stabilisation If your trailer begins to lurch, you can only
stabilise the vehicle/
trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the trailer begins to lurch. ESP ®
slows the vehicle down by brakin gand limit-
ing the engine output until the vehicle/trailer
combination has stabilised.
Traile rstabilisatio nisa ctive above speed sof
about 65 km/h. G
Risk of accident
If road and weather conditions are poor,
trailer stabilisatio nwill not be able to prevent
the trailer from swerving and will thus be
unable to reduce the risk of an accident .Trail-
ers wit hahigh centr eofgravity can tip over
before ESP ®
can detec tthis.
Trailer stabilisation does not work if ESP ®
