160Vehicle care
Tyre pressures differ depending onvarious options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 185.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 201.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
Rear-wheel drive, with twin rear
wheels When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoring
system
The Tyre Pressure Monitoring
System (TPMS) uses radio and
sensor technology to check tyre
pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Tyre pressures in display The current tyre pressures can be
shown in the Driver Information
Centre 3 84.

Vehicle care161
With the vehicle stationary, press
button on end of wiper lever
repeatedly until the tyre pressure
menu is displayed.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 82 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 201.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting low pressure. Check tyre pressure.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w flashes for
several seconds then illuminates continuously together with control
indicator A 3 80 and a
corresponding message appears in
the Driver Information Centre.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for these wheels. For the further three
wheels, TPMS remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.Driver Information Centre 3 84.
Vehicle messages 3 85.
Puncture
A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 80 and a corresponding message
appears in the Driver Information
Centre. Stop vehicle and switch off
engine.
Tyre pressure 3 201, Tyre repair kit
3 164, Spare wheel 3 169, Wheel
changing 3 167.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.

176Vehicle care
Do not clean the engine compartmentwith a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights Headlight and other light covers aremade of plastic. Do not use any
abrasive or caustic agents, do not use
an ice scraper, and do not clean them dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a protective film, making waxing
unnecessary.Unpainted plastic body parts must not
be treated with wax or polishing
agents.
Matt filmed body parts or decor tapes must not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes if the vehicle is equipped with theseparts.
Matt painted decor parts, e.g. mirror housing cover, must not be polished.
Otherwise these parts would become
agleam or the colour would be
dissolved.
Windows and windscreen wiper blades Use a soft lint-free cloth or chamoisleather together with window cleaner
and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.Clean smearing wiper blades with a
soft cloth and window cleaner.
Wheels and tyres Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage
Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
