176Vehicle careWinter tyresWinter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the maximum speed sticker in the driver's field of view.

Fit directional tyres such that they roll
in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
The tyre pressure information label
on the driver's door frame indicates
the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
Tyre pressures 3 219.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 201.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 219.
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.
Vehicle care1795 seconds to initialise recalculation. A
corresponding message appears in
the DIC.
Several minutes of driving at a speed
above 25 mph may be required to
complete the relearn process. The
system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the DIC.
Driver Information Centre (DIC) 3 89.
Vehicle messages 3 90.
General information
The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.
Tyre repair kit 3 180, Tyre chains
3 180.
External high-power radio equipment
could disrupt the TPMS.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm (4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel size
If tyres of a different size than those fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
186Vehicle careCaution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is held under the
vehicle frame using a winch and
secured by tightening a cable using
the wheel wrench and adapters
(depending on vehicle).
It may be necessary to jack the
vehicle up to gain access to the spare
wheel on a fully loaded vehicle with a flat rear tyre.
To release the spare wheel, loosen
cable by connecting the wheel
wrench and adapters (depending on
vehicle) to the slot position illustrated
and lower the wheel fully by turning
wrench clockwise.
Caution
Only use the wheel wrench and
adapters (depending on vehicle)
to lower the spare wheel.
The use of pneumatic tools is
prohibited. This may result in
damage to the winch cable and
equipment.
Place wheel upright, unclip retainer
from wheel rim and release the wheel
from the cable and connected
retainer by routing these components through the centre of the wheel.
Twin rear wheel vehicles have an
additional mounting plate attached to
the spare wheel. Before using the
wheel, undo the nut and remove the
mounting plate.
Vehicle care187
When reinstalling a spare wheel, first
attach the mounting plate (twin rear
wheel vehicles) and secure with the
nut.
Place wheel upright, then route the
cable and connected retainer from
the front of the wheel (side with tyre
valve) and through the centre of the
wheel. Attach the retainer and clip it
into place, ensuring it is correctly
positioned and that the front of the
wheel (side with tyre valve) will be
facing upwards when reinstalled.
Place wheel below the vehicle frame,
directly beneath the winch
mechanism, then tighten cable using
the wheel wrench and adapters by
connecting to the slot position
illustrated above and turning wrench
anticlockwise until the wheel is
secured in the fully raised position.9 Warning
Ensure the front of the wheel (side
with tyre valve) is facing upwards
when the spare wheel is
reinstalled below the vehicle
frame.
Temporary spare wheel
Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
50 mph. Take curves slowly. Do not
use for a long period of time.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 180.
Summer and winter tyres
If you use winter tyres, the spare
wheel may still be fitted with a
summer tyre.
If you use the spare wheel when it is
fitted with a summer tyre the vehicle's driveability may be affected,
especially on slippery road surfaces.
Directional tyres Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Vehicle care193Unpainted 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 these
parts.
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 chamois
leather 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.Remove dirt residues from smearing wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
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 damageRectify 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.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Towing equipment
Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Interior care Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean leather upholstery with clear
water and a soft cloth. In case of
heavy soiling, use leather care.
