Importan tsafety notes G
WARNING
Certain components in th eengine compart-

the radiator fan. There is arisk of injury.
If you have to carry out work in the engine
compartment:
R switch off the ignition
R never touch the dangerous area ssurround-

area of the fan
R remove jewellery and watches
R keep items of clothing and hair, for exam-
ple,a wayfrom moving parts. G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Make sure that engine oil does not spil lout
over the filler neck. Allow the engine to cool
downa nd thoroughly clea nthe components
that have come into contact with engine oil
before you start the engine. G

WARNING
Braking efficiency is reduced after the vehicle has been washed. There is arisk of an acci-
dent.
After washing the vehicle, brake carefully
while paying attention to the traffic conditions in order to restore full braking efficiency.
! When the HOLD function is activated, the
vehicl ebrakes automatically in certain situa-

To avoi ddamage to the vehicle, deactivate
the HOLD function in the following or similar
situations:

The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, wash off excess dirt
before cleaning the vehicle in an automatic car
wash.
After using an automatic car wash, wipe off the
wax from the windscreen and the windscreen
wiper blades. This will prevent smears and
reduce wiping noises caused by residue on the
windscreen.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements for each indi-
vidual country.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
When washing the underside of the vehicle, also
clean the insides of the wheels.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use asoft sponge to clean.
X Use amild cleaning agent, such as acar

For further information on displaying this mes-
sage, refe rtothe "Checking the tyre pressure
electronically" section (Y page 240).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 238). Note that the correc ttyre pres-
sure for the current operating situation must
first be learnt by the tyre pressure monitor. If a
substantial loss of pressure occurs, the warning threshold for the warning message is aligned to
the learnt reference values. Restart the tyre
pressure monitor after adjusting to the cold tyre pressure (Y page 241). The current pressures
are saved as new reference values. This ensures that awarning message appears only if the tyre
pressure drops significantly.
The tyre pressure monitor does not warn you of
an incorrectly set tyre pressure. Observe the
notes on the recommended tyre pressure
(Y page 238).
The tyre pressure monitor is not abletow arn
you of asudden loss of pressure, e.g. if the tyre
is penetrated by aforeign object. In this event,
bring the vehicle to ahalt by braking carefully.
Avoid abrupt steering manoeuvres.
The tyre pressure monitor has ayellow h
warning lamp on the instrument cluster for indi-
cating apressure loss or malfunction. Depend-
ing on how the warning lamp flashe sorlights up,
at yre pressure that is too low or amalfunction in
the tyre pressure monitor is indicated:
R if the h warning lamp is lit continuously,
the tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure monitor
is not malfunctioning.
R if the h warning lamp flashe sfor around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the hwarning lamp,am essage
appears in the multifunction display. Observe
the information on display messages
(Y page 150).
It may take up to ten minutes for amalfunction
of the tyre pressure monitor to be indicated .A
malfunction willbei ndicated by thehtyre
pressure warning lamp flashing for approx-
imatel yone minute and then remaining lit. When
the faulth as been rectified, the htyre pres-
sure warning lamp goes out after driving for a
few minutes. The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at
afilling station using apressure gauge.
The tyre pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by apressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interferenc efrom radio transmit-
ting equipment (e.g. cordless headphones, two- way radios) that may be being operated in or
near the vehicle.
