Risk of acciden
tand inju ry
Always have work on the vehicle carried out
by aq ualified specialist workshop. In particu-
lar, work relevant to safety or on safety-rela-
ted systems as well as maintenanc ework
must be carried out at aqualified specialist
workshop. The workshop must have the nec-
essary specialist knowledge and tools to carry
out the work required. Mercedes-Ben zrec-
ommends that you use aMercedes-Benz
Servic eCentr efor this purpose. G
Ris
kofa ccident and inju ry
Some safety sys tems only functio nwhen the
engin eisrunning. You should therefor enever
switch off th eenginew hen dri ving. Otherwise,
th es afety systems of your vehicl emaynot
functio ncorrect lyand as aresul twillnol on-
ge rp rotect you and other persons as inten-
ded. In addition, there is arisk that you may
lose control of you rvehicle and thus cause an
accident. G
Risk of accident and injury
Work carried out incorrec tly, or alterations
made to the vehicle, e.g. re-routing of cables
under coverings, could cause the safety sys-
tems of your vehicle to stop working properly.
The safety systems would thus no longe rpro-
tect yo uand othe rpersons as intended. In
addition ,there is arisk that you may lose con-
trol of your vehicle and thus cause an acci-
dent.
All work and alteration stothe vehicle, e.g.
installation sormodifications, should there-
for ebec arried out at aqualified specialist
workshop. G
Risk of accident
If you driv eover obstacles at hig hspeed or if
the vehicl ebottoms out in rough ter rain, it
could cause heavy impact stothe vehicle
underbody, tyres or wheels. This coul dcause
your vehicle to be damaged, which in turn
might lead to an accident. This also applies to
vehicles which are equippe dwith underbody
protection.
You should therefore drive over obstacles
slowly. Preven tthe vehicle from bottomi ng
out when driving off-road and if necessary,
have your vehicle inspected at aqualified spe-
cialist workshop. G
Risk of accident
If work on electronic equipment and its soft-
ware is carried out incorrectly, this equipment
could stop working. The electronic systems
are networked via interfaces. Tampering with
these electronic systems could cause mal-
functions in systems which have not been
modified. Malfunctions such as these can
seriously jeopardis ethe vehicle' soperating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications to electronic components carried
out at aqualified specialist workshop. Vehicle registration
Mercedes-Benz may ask its Service Centres
to carry out technical inspections on certain
vehicles to improve their quality or safety.
If you did not purchase your vehicle from an
authorised specialist deale rand your vehicle
has never bee ninspected at aMercedes-
Benz Servic eCentre, it is possible that your
vehicle is not registered in your nam ewith
Mercedes-Benz. Mercedes-Ben zcan only
inform you about vehicle check sifithas your
registration data.
It is advisabl etoregister your vehicle with a
Mercedes-Ben zService Centre. Introduction

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

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.
