2020 MASERATI GRANTURISMO CONVERTIBLE overheating

Insufficient tire inflating pressure can
cause tire overheating and possible
internal damage, which may even lead
to the tire destruction.
CAUTION!
After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve stem,
which could damage it.
Impacts with curbs, holes, and
obstacles in the road, and prolonged
trips on rough roads can cause tire
damage which may not be visible to
the naked eye.
Check your tires regularly for any signs
of damage (e.g. scratches, cuts, cracks,
bulges, etc.). If sharp objects penetrate
the tires, they can cause structural
damage which is only visible when the
tire is removed.
In any case, any possible damage must
be inspected by an experienced tire
fitter, as it may seriously reduce the
tire life.
Remember that tires deteriorate with
time, even if used little or not at all.
Cracks in the tire tread and sides,
alongside possible bulging, are a sign
of deterioration.
WARNING!
•Check the inflating pressure of the
tires when cold, at least every two
weeks and before long trips.
•Have the old tires inspected by an
experienced technician, to make sure
they can still be used safely. If the
same tire has been on your vehicle
for 4 or 5 years, have it inspected
anyway by an experienced
technician.
•Never fit tires of uncertain origin.
•“Directional” tires have an arrow on
their side showing the rolling
direction. To keep the best
performance when replacing a tire,
make sure that the rolling direction
corresponds to the one shown by
the arrow.
•During the tire life, the rolling
direction used for the first fitting
shall always be observed, also in
case of “nondirectional” tires.
•Check the depth of the tire tread at
regular intervals. The minimum
allowed value is 0.06 in (1,6 mm) at
that point the wear indicators on the
tire will be visible (see “Tires –
General Information” in section“Driving”). The thinner is the tread,
the greater is the risk of skidding.
•Drive carefully on wet roads to
decrease the risk of aquaplaning.
Winter Tires
These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle.
The features of these tires are
significantly reduced in winter when
tread depth is less than 0.157 in (4
mm). In this case, they should be
replaced.
The specific features of the winter tires
lead to lower performance under
normal environmental conditions or
on long highway trips, compared to
the standard tires.
Therefore, their use should be limited
to the situations and performance for
which they have been type-approved.
TheAuthorized Maserati Dealercan
provide all necessary information
about fitting winter tires on the
vehicle.

Protection from Overheating
The supplied battery charge
maintainer features a protection
against overheating.
In case ambient temperature
increases, output power is reduced.
Service
• Battery maintainer does not require
any maintenance.
• Do not disassemble the battery
maintainer.
• The maintainer case can be cleaned
with a soft damp cloth or using mild
detergent.
• Always disconnect the maintainer
from the mains before cleaning it.

Tire Inflation Pressure
Tire Pressure
Front and rear 220 kPa - 2,2 bar
-32psi
Spare wheel
(optional)350 kPa - 3,5 bar
-51psi
NOTE:
•For more information about the
pressure check methods, see “Tires –
General Information” in section
“Driving”.
•The tire inflation pressure value are
also indicated on the driver's side at
the base of the rear door pillar.
WARNING!
•Improperly inflated tires are
dangerous and can cause collisions.
•Under-inflation increases tire flexing
and can result in tire overheating
and failure.
•Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and potholes can cause damage
that result in tire failure.
•Over-inflated or under-inflated tirescan affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
•Unequal tire pressures can cause
steering problems. You could lose
control of your vehicle.
•Unequal tire pressures from one side
of the vehicle to the other can cause
the vehicle to drift to the right or
left.
•Always drive with each tire inflated
to the recommended cold tire
inflation pressure.
