196Vehicle careRelearn function
After a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, the tyre
pressure monitoring system needs to recalculate.
Tyre pressure 3 239, Tyre repair kit
3 198.
During driving, select the tyre
pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. five seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving at a speed above 40 km/h 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 Driver Information
Centre.

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 3 198, Tyre chains
3 197.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, the
tyre pressure monitoring system
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 two-
three mm (four 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 two 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
Vehicle care197indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every six 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.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
drive wheels.
On vehicles with twin rear wheels,
tyre chains are only permitted on the
outer wheels.
Always use fine mesh chains that add no more than 15 mm to the tyre tread
and the inboard sides (including chain lock).
9 Warning
Damage may lead to tyre blowout.
Vehicle care2039. Refit wheel cover.Note
If applicable, fit anti-theft bolts
nearest the tyre valve (otherwise it
may not be possible to refit the wheel
cover).
10. Stow the replaced wheel 3 203
and the vehicle tools 3 192.
11. Have the new wheel balanced on the vehicle. Check the tyre
pressure of the installed tyre
3 239 and also the wheel bolt/nut
torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel Some vehicles are equipped with atyre repair kit instead of a spare wheel
3 198.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.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.
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.
Vehicle care205Then 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
80 km/h. 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 3 197.
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.
The following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.● Do not drive faster than 80 km/h.
● Drive particularly carefully on wet
and snow-covered road
surfaces.
Vehicle care211For 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.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light- coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.
