Spark plugs
In order to help ensure that the
engine works efficiently and to keep
polluting emissions at a minimum
level, it is essential that the spark
plugs are sound and clean.
WARNING: The spark plugs must be
changed at the intervals indicated in
the Maintenance Schedule. Only use
the prescribed spark plugs: faults may
arise if the heat rating is unsuitable,
or if the specified service life is not
guaranteed.
Wheels and tires
The Maserati Granturismo S
is a performance automobile.
Tire wear must be checked
regularly and worn tires must be
replaced. Tire wear will vary and
depends on driving habits and
condistions. To help obtain optimal
performance and the longest service
life from the tires, comply with the
following precautions during the first
300 mi (500 km):
- do not drive at the maximum speed
of the vehicle
- 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 tires
WARNING: The tires must be always
maintained in good conditions to help
ensure safe driving.
Tire inflation pressure must
correspond to the prescribed values
and should be checked only when the
tires are cold: tire pressure increases
as the tire temperature progressively
increases.
Never reduce the pressure if the tires
are hot.
Insufficient tire inflating pressure can
cause tire overheating and possible
internal damage, which may even
lead to tire destruction.
Check the tire inflating
pressure at least every two
weeks and before long trips.
