Vehicle care191Tread depthCheck 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.
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
3 189.9 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.
192Vehicle careTyre chains
Tyre chains are only permitted on the
front wheels.
Always 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 3 186.
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.
Vehicle care19711. Stow the replaced wheel 3 197
and the vehicle tools 3 186.
12. Have the new wheel balanced on the vehicle.
Check the tyre pressure of the
installed tyre 3 223.
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
3 192.
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.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.
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.
Wheel changing 3 195.
The spare wheel is mounted under
the rear underbody and may be
secured using a security bolt that can
only be removed using the wheel bolt sleeve supplied.
Vehicle tools 3 186.9 Warning
Due to the weight of the tyre
assembly, exercise caution when
releasing the spare wheel carrier.
Do not fully remove bolt 1.
Support the spare wheel with a
suitable object to prevent the
wheel falling suddenly when
loosening the carrier bolts - risk of injury!
To release the spare wheel carrier,fully remove bolt 2 then loosen bolt 1,
ensuring it is not fully removed. Then
move the spare wheel carrier up and
down and from side to side, until it
clears bolt 1, and lower the carrier
assembly.
When installing the wheel ensure that
the spare wheel carrier is correctly
positioned before tightening the bolts.
