ESP MASERATI GRANTURISMO 2019 Repair Manual

Wheels Maintenance Tires Maintenance CAUTION!
To obtain the best performances and
the longest mileage from the tires,
take the following precautions during
the first 310 mi (500 km):
• do not drive at the vehicle’s
maximum speed;
• drive at low speed on curves;
• avoid sudden steering;
• avoid sudden braking;
• avoid sudden acceleration;
• do not drive at high speeds for too
long.
The tires inflation pressure must
correspond
to the prescribed values
(see the chapter “Tire Inflation
Pressure” in section “Features and
Specifications”) and should be checked
only when the tires have cooled down.
In fact, the pressure increases as the
tire temperature progressively
increases.
Never reduce the pressure if tires are
hot (see “Tires – General Information”
chapter in section “Driving”). 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 sectionMaintenance and Care

that all the electrical/electronic
systems in the vehicle work efficiently.
Maintaining Battery Charge If you perform short daily trips
(approximately 10 miles/16 km), which
correspond to an annual total of 4000
miles/6000 km, or when the vehicle is
not going to be used for one week or
more, Maserati recommends
connecting the vehicle to a battery
charger, to save you the trouble of
having to recharge the battery (see
“Battery Charge Maintainer
Operation” in this chapter).
The battery charge maintainer will
keep the battery charged properly and
at the correct voltage levels required
by the systems and devices in the
vehicle.
Before using the battery charge
maintainer, carefully follow the
instructions provided.
If you do not use a battery charge
maintainer to prevent the battery
from going dead when you are not
going to use the vehicle for long
periods of time, you need to check
and recharge the battery at least once
every three weeks. Make this check if
you perform short daily trips
(approximately 10 mi/16 km) which
correspond to an annual total of 4000 miles/6000 km. Please note that
allowing the battery to go dead
repeatedly can cause premature wear
on the internal cells and greatly
reduce their life, leading to problems
with the ignition system and other
electrical/electronic systems.
The Authorized Maserati Dealer is
available to advise you on how to
recharge your battery correctly and
give you useful information on battery
care and maintenance.
NOTE:
The Authorized Maserati Dealer can
provide you with any information
about the Maserati approved “Battery
Charger and Conditioner”, available in
the “Genuine Accessories” range.
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
dangerous gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times:
• always charge or recharge the
battery in a well-ventilated
environment; • never charge or recharge a battery
that has frozen: it can explode due
to hydrogen trapped inside the ice
crystals;
• ensure that any sparks or open
flames are nowhere near the battery
while it is charging;
• before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
connected to the battery safely and
correctly.
