228Vehicle careWheels and tyres
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 at temperatures below 7 °C and shouldtherefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.4-door saloon
Tyre size 205/65 R16 is only suitable
as a winter tyre.
All engines except A14XER,
B14XER, B14NEL, B14NET,
B14NET LPG, B16XER:Tyre size 215/50 R17 is only suitable
as a winter tyre.VXR with Michelin Pilot Super Sport
tyres
This model is factory-fitted with high performance sports tyres, which have
a reduced performance at low
temperature.9 Danger
Use winter tyres at temperatures
below 0 °C, otherwise damage of
the high performance sports tyres
is possible.

Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Performance 3 263.
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.

Vehicle care2339. Proceed to the right side frontwheel, and repeat the procedure
in Step 8.
10. Proceed to the right side rear wheel, and repeat the procedure
in Step 8.
11. Proceed to the left side rear wheel, and repeat the procedure
in Step 8. The horn sounds twice
to indicate the sensor
identification code has been
matched to the left side rear tyre,
and the tyre pressure sensor
matching process is no longer
active.
12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
14. Ensure the tyre loading status is set according to the selected
pressure 3 92.
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
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. 3 2309 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.

234Vehicle careWheel coversWheel 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, do not
attach wheel covers.
Tyre chains
Use tyre chains only on front wheels.
9 Warning
Damage may lead to tyre blowout.
4-door saloon
