204Vehicle careWheels and tyres
Wheels
On vehicles with Diesel engines no
steel rims and only special, for this
vehicle approved alloy wheels are
permitted.
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.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and should
therefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 239.Use tyre size 225/55 R17 only as
winter tyres.
On vehicles with Diesel engines, no
steel rims and only special, vehicle-
approved alloy wheels are permitted.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
Tyre designationsE.g. 235/55 R 17 99 V235=Tyre width, mm55=Cross-section ratio (tyre height
to tyre width), %R=Belt type: RadialRF=Type: RunFlat17=Wheel diameter, inches99=Load index e.g. 99 is
equivalent to 775 kgV=Speed code letter
Speed code letter:
Q=up to 160 km/hS=up to 180 km/hT=up to 190 km/hH=up to 210 km/hV=up to 240 km/hW=up to 270 km/hDirectional 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.
Tyre pressure Check the pressure of cold tyres atleast every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Unscrew the valve cap.
Tyre pressure 3 239.

Vehicle care209
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
is the same as before.
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.
Vehicles with steel wheels: When
using locking wheel nuts, the wheel
covers might not be attached to the
steel wheels.

210Vehicle careTyre chains
Use tyre chains only on front wheels.
Tyre chains are permitted on tyres of
size 225/55 R 17. 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.
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 tyre's sidewall 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 you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is in a box under the
floor cover in the load compartment.

216Vehicle care
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.
If mounting a spare wheel, which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
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.
Removing the spare wheel and
stowing a damaged wheel in the load compartment
The spare wheel is located in the
spare wheel well beneath the floor
cover.
The spare wheel well is not designed
for other tyre sizes than spare wheel.
To remove: 1. Close the soft top and fold in the load compartment partition by
pushing at the loop area upwards
to the inside 3 73.
2. Remove the floor cover.
3. The spare wheel is secured with a
wing nut in the well. Untwist nut,
