Setting the vehicle geometry
Incorrect wheel alignment at the front or rear leads to excess wear on the
tyres and impairs driving safety. In the event of prominent tyre wear, we rec-
ommend that you have the setting of the vehicle geometry checked at a spe-
cialist garage.
WARNING
An incorrect wheel alignment at the front or rear impairs handling.
■
Unusual vibrations or pulling of the vehicle to one side could be a sign of
■
tyre damage. If there is any doubt that a wheel is damaged, immediately re-
duce your speed and stop! If no external tyre damage is evident, drive slow-
ly and carefully to the nearest specialist garage to have the vehicle
checked.

Wear indicators
There is a 1.6-mm-high wear indicator
the tyres. In some countries, different tyre wear rates may apply.
Markings on the walls of the tyres through the letters "TWI", triangular sym-
bols or other symbols identify the position of the wear indicators.
Replacing the wheels
For uniform wear on all tyres, we recommend that you replace the wheels ev-
ery 10,000 km as shown in the diagram
proximately the same life for all the tyres.

WARNING
You must have your tyres replaced with new ones at the latest when the
■
wear indicators have been worn down.
Worn tyres do not provide the necessary adhesion to the road surface
■
particularly at high speeds on wet roads. One could experience "aquaplan-
ing" (uncontrolled movements of the vehicle – "swimming" on a wet road
surface).
Tyre damage

Read and observe on page 201 first.
We recommend checking your tyres and wheel rims for damage (punctures,
cuts, splits and bulges, etc.) on a regular basis.
Remove any foreign objects in the tyre tread immediately (e.g. small stones).
Foreign bodies which have penetrated into the tyre (e.g. screws or nails)
should not be removed and seek help from a specialist garage.
WARNING
Never drive with damaged tyres – risk of accident.
CAUTION
The tyres must be protected from contact with substances such as oil, grease
and fuel, which could damage them. If the tyres come into contact with these
substances, then we recommend having them checked out in a specialist ga-
rage.
Unidirectional tyres

Read and observe on page 201 first.
The direction of rotation of the tyres is marked by arrows on the wall of the
tyre.
The indicated direction of rotation must be adhered to in order to obtain the
best benefits from the characteristics of these tyres.
