192Vehicle care
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
nominal tyre pressure and make
other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.
Tyre pressure monitoring system
3 190.9 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
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.
Vehicle care193Always use fine mesh chains that add
no more than 15 mm to the tyre tread
and the inboard sides (including chain
lock).
For tyre size 215/60 R17, consult a
workshop.9 Warning
Damage may lead to tyre blowout.
Wheel covers on steel wheels may
come into contact with parts of the
chains. In such cases, remove the
wheel covers.
Tyre chains may only be used at
speeds up to 50 km/h and, when
travelling on roads that are free of
snow, they may only be used for brief
periods since they are subject to rapid wear on a hard road and may snap.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread or
sidewall can be repaired with the tyre
repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding four mm or
that is at tyre sidewall near the rim
cannot be repaired with the tyre repair kit.9 Warning
Do not drive faster than 80 km/h.
Do not use for a lengthy period.
Steering and handling may be
affected.
If the vehicle has a flat tyre:
Apply the parking brake and engage
first gear or reverse gear.
The tyre repair kit is located under the
driver's seat.
Vehicle tools 3 187.
1. Remove the compressor and sealant bottle from the tyre repairkit case.
2. Remove the electrical connection cable and air hose from the
compartments on the underside
of the compressor.
3. Screw the air hose to the connection on the sealant bottle.
4. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
5. Unscrew valve cap from defective
tyre.
Vehicle care197
3.Place lifting pad spigot of the jack
under the jacking hole located
nearest the wheel concerned.
Ensure the jack is positioned
correctly. The jack base must be
on the ground directly below the
jacking hole in a manner that
prevents it from slipping.
4. Install wrench onto the jack and raise the vehicle by turning the
wrench until the wheel is clear of
the ground.
5. Unscrew wheel bolts completely by turning anticlockwise and wipe
clean with a cloth.
Put wheel bolts somewhere
where the threads will not be
soiled.
6. Change the wheel. Spare wheel 3 197.
7. Screw in the wheel bolts.
8. Lower the vehicle and remove jack.
9. Tighten each of the wheel bolts in
a crosswise sequence using the
wheel wrench. Ensure the wrench is securely located. The wrench
should turn clockwise to tighten
the bolts. Invert the wrench if
necessary.
Tightening torque is 160 Nm.
10. Replace the wheel cover, ensuring that the valve hole in thewheel cover is aligned with the
tyre valve before installing.
Note
If applicable, fit anti-theft bolts
nearest the tyre valve (otherwise it
may not be possible to refit the wheel
cover).11. Stow the replaced wheel 3 197
and the vehicle tools 3 187.
12. Have the new wheel balanced on the vehicle.
Check the tyre pressure of the
installed tyre 3 216.
Check the wheel bolt torque.
Have the defective tyre renewed or
repaired as soon as possible.
Spare wheel
Some vehicles are equipped with a tyre repair kit instead of a spare wheel
3 193.
The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted wheels and country
regulations. In this case a permissible maximum speed applies, even
though no label at the spare wheel
indicates this.
