WARNING
The electrically adjustable steering wheel can
still be adjusted when there is no key in the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle, as they could
become trapped if the steering wheel is adjus-
ted. G
WARNING
Only adjust the steering wheel when the vehi-
cle is stationar yand do not pull away until the
steering wheel adjustment mechanis mis
locked in position. You might otherwise drive
without the steering wheel adjustment mech-
anism being locked in position. As aresult,
you could be distracted from road and traffic
condition sbyanunintentional movement of
the steering wheel and thereby cause an acci-
dent.
However, the steerability of the vehicl eisnot

approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range dependin gonthe dis-
tance to the other vehicle. Onc ethe system

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
componen tofthe engin emanagement system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop, e.g. aMercedes-Benz Servic eCentre.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolan
ttempera-
tur ed isplay is showing
more than 120 †. The
coolant warnin glamp
may also be on 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 321). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct
,the radiator fa nmay be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X At coolant temperatures under 120 †, drive on to the nearest
qualified specialis tworkshop, 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 traffic. Automa

WARNING
The movement of the pedal smust not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you to lose control of your vehicle and cause an
accident. DIRECT SELECT lever

R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example.

WARNING
Only remove the key from the ignition lock
when the vehicle is stationary, as you can not
steer the vehicle when the key is removed.
Never leav echildren unsupervised in the vehi-
cle. They might release the electric parking
brake. This coul dlead to aserious or fatal
accident. G
WAR
NING
Under no circumstances should the exhaust
system come into contact with flammable
materials such as dry grass or petrol ,for
example. Do not par kthe vehicle on dry grass-
lan dorh arvested grain fields. The hot exhaust
system could otherwise ignite the flammable
material and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on steep uphill or downhill gradients, turn
the fron twheels towards the kerb. Switching of

WARNING
Neve rswitch off the engine while the vehicle
is in motion.
There is no brake boost for the service brake
if the engine is not running. If the ignition is
switched off, there is also no power assis-
tance for the steering.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident.
