Tyre repair kit 3 154.
Spare wheel 3 159.Wheels and tyres
Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Tyres Factory-fitted tyres are matched to
the chassis and offer optimum driving comfort and safety.
Winter tyres Winter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.

152Vehicle care
In accordance with country-specific
regulations, a notice indicating the
maximum permissible speed for the
tyres must be affixed within the
driver's field of vision.

Speed code letter:
Q=up to 100 mphS=up to 112 mphT=up to 118 mphH=up to 130 mphV=up to 150 mphW=up to 168 mphTyre pressure
Check the pressure of cold tyres at least every 14 days and before any
long journey. Do not forget the spare
wheel.
Tyre pressures 3 189.
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.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.
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.

twin rear wheels), 264 Nm (Rear-wheel drive with single rear
wheels).
9. Refit wheel cover.
10. Stow the replaced wheel 3 159
and the vehicle tools 3 150.
11. Have the new wheel balanced on the vehicle. Check the tyre
pressure of the installed tyre
3 189 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 a tyre repair kit instead of a spare wheel 3 154.Caution
The use of a spare wheel that is
smaller than the other wheels or in combination with winter tyres
could affect driveability. Have thedefective 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 adapter.
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 using the wheel wrench and
adapter and lower the wheel fully.
Caution
Only use the wheel wrench and
adapter 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, remove pin from retainer and release the wheel from
the cable.

160Vehicle care
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.
When reinstalling a spare wheel,
attach the mounting plate and secure with the nut.
When installing a spare wheel, route
the cable from the back and through
the centre of the wheel. Attach the
retainer and pin, ensuring it is
correctly positioned and that the front
of the wheel will be facing
downwards. Tighten cable using the
wheel wrench and adapter until the wheel is secured.
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.
■ Do not drive faster than 50 mph.
■ Drive particularly carefully on wet and snow-covered road surfaces.Jump starting
Do not start with a quick charger.
A vehicle with a discharged battery
can be started using jump leads and
the battery of another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact with eyes, skin,
fabrics, and painted surfaces. The fluid contains sulphuric acid which can cause injuries and damage in
the event of direct contact.

Vehicle care165
Windows and windscreen wiperblades
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.
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.
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 upholsteryOnly 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.
