Operation
Information on driving
Check the tyre pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tyres are damaged. If you suspect that
a tyre is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the wheels and tyres for damage. Hidden
tyre damage could also be causing the unusual
handling characteristics. If you find no signs of
damage, have the tyres and wheels checked at a
qualified specialist workshop.
When parking your vehicle, make sure not to
squash the tyre. If you cannot avoid driving over
obstacles, e.g. kerbs, do so slowly and at an
obtuse angle only. You could otherwise damage
the wheel rims and tyres.
Regular checking of wheels and tyres

WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
