gered unintentionally
.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

0for aconsiderable time.
X Remove the key and reinsert it int othe ignition lock.
X Chec kthe starter battery and charge it if necessary
(Y page 285).
X Star tthe engine. The on-boar
dvoltage is too low.
X Switch off non-essential consumers, e.g. seat heatin gorinterior
lighting ,and try to turn the key again.
If this doe snot work:
X Check the starter battery and charge it if necessary
(Y page 285).
or
X Jump-start the vehicle (Y page 289).
or
X Consult aqualified specialist workshop. Doors

You can open adoor from inside the vehicle
even if it has been locked. X
Pull door handle ;.
If the door is locked, locking knob :pops

opened.
i When adoor is opened, the side window
on that side opens slightly .When the door
is closed ,the side window closes again. !
The side windows will not open/close if
the battery is discharged or if the side win-
dows hav eiced up. It wil lthen not be pos-
sible to close the door. Do not attemp tto

Changing bulbs
Important safety notes
Xenon bulbs If your vehicle is equipped wit
hxenon bulb s,
you ca nrecognise this by th efollowing: the
cone of light from th exenon bulbs moves
from th etop to the bottomand back again
whe nyou star tthe engine. Fo rthis to be
observed ,the lights must be switched on
before startin gthe engine. G
Risk of injury
Xenon bulb scarry ahigh voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con-
tacts on xenon bulbs. Therefore, never
remov ethe cover from xenon bulbs.
Do not change xenon bulbs yourself, but have
them replaced at aqualified specialist work-
sho pwhich has the necessar yspecialist
knowledge and tools to carry out the work
required.
Mercedes-Ben zrecom mends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that thes efunction correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs G
Risk of injury
Bulbs and lights can become very hot. For this
reason, allow them to cool down before
changin gthem. Otherwise, you coul dburn
yourself when you touch them.
Keep bulbs out of the reach of children. Oth-
er wise ,they could damage them, for example,
and inj uret hemselves.
Never use abulbw hich ha sbeend ropped.
Suc hab ulbm ay explod eand injure you. Halogen bulb
sare pressu rised and could
explode when yo uchange them, especiall yif
the yarever yhot. Yo ushould therefor ewear
eye protec tion and gloves when you are
changing them.
There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 113). Hav ethe bulbs that
you cannot replac eyourself changed at a
qualified specialist workshop.
Mercedes-Ben zrecom mends that you use a
Mercedes-Ben zService Cent refor this pur-
pose .Inp articular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
If you require assistanc echangi ngbulbs, con-
sult aqualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn int othe glass surface and reduce
the servic elife of the bulbs. Always use alint-
free clot horonly touch the bas eofthe bulb
when fit ting.
Only use bulb softhe cor rect type.
If the new bul bstill doe snot light up, consult
aq ualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.

Problem Possible causes/consequences and

Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or amechanical
componen tofthe engin emanagement system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. (Y
page 192). The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soo naspossible and allow the engin eand the coolant
to cool down.
X Check the coolant level (Y page261). Observe the warning
notes as you do so and top up the coolan tifnecessary. If the coolan
tlevel is correc t,the radiator fan may be faulty. The
coolant is too hot and the engine is no longe rbeing cooled suffi-
cien tly.
X If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Manual transmission

Whe nshifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift uninte ntionally into 3rdor4th gear
and damage the transmission. Do not exceed the maximum speed for the
individual gears.
Shiftin
gdown at too high aspeed (trans-
mission braking) can cause the engine to
overrev ,leading to engine damage.
! On long and steep downhill gradients,
especiall yifthe vehicle is laden or towing
at railer, yo umust shift into gear 1, 2or3
in good time. This uses the engine's braking
effect .This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Neutral
