WARNING
Modifications to or work performe dincor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, beltt en-
sioners, belt forc elimiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration forc ebeing sufficien ttotrig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction SRS consist
sof:
R the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS reduces the risk of occupant scoming
into contact with the vehicle's interior in the
event of an accident .Itcan also reduce the
effect of the forces to which occupant sare
subjected during an accident.
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. 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 started. G
WARNING
If SRS is malfunctioning, 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 when the ignition is switched on.
R the engine is runnin gand the 6SRS
warning lamp does not 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 Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
aq ualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in alongitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of ac ollision. In the first deployment stage, Occupant safety

Important safety notes
Xenon bulbs If your vehicle is equipped with xenon bulbs,
you can recognise this by the following: the
cone of light from the xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before startingt he engine. G
DANGER
Xenon bulbs carry 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
remove the cover from xenon bulbs.
Do not change xenon bulbs yourself, but have
them replaced at
aqualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor 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 these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 122). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
If you require assistanc echangin gbulbs, con-
sult aqualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the servic elife of the bulbs. Always use alint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
aq ualified specialist workshop.

Problem Possible causes/consequences and
M Solutions
Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop, e.g. aMercedes-Benz Service Centre.
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. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 283). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X
At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop, e.g. to aMercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Manual transmission
Gear lever
Gear lever
!
Only engage gear when the clutch pedal
is depressed.
! When shifting between 5thand 6thgear,
you should always push the gear lever all the way to the right. Otherwise, you could
shift unintentionally into
3rdor4th gear
and damage the transmission.
If you shift down at too high aspeed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise arisk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing
at railer, you must shift into gear 1, 2or3
in good time. This uses the engine's braking
effect.T his relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Manual transmission
