Vehicle care175Changing 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
front wheels.
Always use fine mesh chains that add no more than 10 mm to the tyre tread
and the inboard sides (including chain lock).9 Warning
Damage may lead to tyre blowout.
Tyre chains are only permitted on
tyres of size 175/70 R 14,
185/60 R 15, 185/65 R 15 and 195/55 R 16.
Tyre chains are not permitted on tyres of size 215/45 R 17 and 225/35 R 18 .
The use of tyre chains is not permitted
on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.

Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a spare
wheel.
The spare wheel is classified as a
temporary spare wheel depending on the size compared to the other
mounted wheels and country
regulations.
The spare wheel has a steel rim.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 located in a holder
beneath the vehicle floor.

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 size tyre in the
rear.
Tyre chains 3 175.
Directional tyres
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.
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.
■ Drive particularly carefully on wet and snow-covered road surfaces.Jump starting
Do not start with a quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning

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
