Wheels and tyres

To obtain the best
performance and the
longest service life from
the tyres, comply with the following
precautions during the fi rst 500 Km
(300 mi):
- do not drive at the vehicle's
maximum speed;
- drive on curves at low speed;
- avoid sudden steering;
- avoid sudden braking;
- avoid sudden acceleration;
- do not drive long at high speeds
for too long.
How to use the tyres
WARNING: The tyres must be always
maintained in good conditions to
ensure safe driving.
Tyre infl ation pressure must
correspond to the prescribed values
and should be checked only when the
tyres are cold: the pressure increases
as the tyre temperature progressively
increases.
Never reduce the pressure if tyres are
hot.
Insuffi cient tyre infl ating pressure can
cause tyre overheating and possible
internal damage, which may even
lead to tyre destruction.
Check the tyre infl ating
pressure at least every two
weeks and before long trips.
