Information Centre with
Uplevel-Display.
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.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
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.
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.
192Vehicle careTyre 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 195/65 R 15,
205/55 R 16 and 225/45 R 17.
Tyre chains are not permitted on tyres of size 225/40 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.
Tyre damage exceeding 4 mm or that
is at the tyre's sidewall near the rim
cannot be repaired with the tyre repair kit.9 Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is in the stowage
compartment in the load
compartment.
To open the compartment, disengage the cover and open it.
198Vehicle care
Jacking position for liftingplatform
Rear arm position of the lifting
platform at the underbody.
Front arm position of the lifting
platform at the underbody.
Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a spare
wheel.
The spare wheel can be 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.
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 the load
compartment beneath the floor
covering. It is secured with a wing nut.
The spare wheel well is not designed for all permissible tyre sizes. If a
wheel wider than the spare wheel has
to be stowed in the load
compartment, it needs to be secured with a strap or, depending on the
version, with an extension bar.
