2020 MASERATI GRANTURISMO flat tire

7 lbf·ft / 98 ± 10 Nm). This is
equivalent to a load of
approximately 44 lb (20 kg) being
placed on the handle of the wrench
supplied when extended for use.
•After refitting the standard wheel,
check the tire pressure.
Once finished:
• completely deflate the compact
spare wheel by pressing on the valve
with the overhang of the valve cap;
• wrap the power cable and the
inflation hose inside the compressor
case;
• place the compressor, the jack, the
wrench and the adapter in the
container inside the compact spare
wheel;
• put the compact spare wheel in its
bag and put it back in the trunk
compartment.
Emergency Release of the
Parking Brake
In the event the electric parking brake
locks due to a total system failure (see
“Parking Brake” in section “Driving”),
it is not possible to move the vehicle,
since the thrust action of the brake
shoes will lock the rear wheels.
For moving the vehicle it is therefore
necessary to manually act on the
electric actuator to release the
pressure of the brake shoes on the
rear wheels by performing the
following operation.
CAUTION!
If the parking brake has been
activated in manual or automatic
mode and it is not possible to release
it by operating on the lever of the
central console, do not move the
vehicle since rear brake calipers might
be damaged. If you are not able to
perform the following operation, to
move the vehicle, load it on a rescue
vehicle, avoiding to move it. For more
information on vehicle towing, see
"Towing a Disabled Vehicle" chapter
in this section.
Manual Release Procedure
To manually release the parking brake,
you need to use the special tool
provided in the tool kit (see "Tool Kit"
in this section).
Proceed as follows:
• remove any luggage and/or the bag
containing the compact spare wheel
(if equipped) from the trunk
compartment;
• remove the floor panel from the
trunk compartment;
• remove the inside covering panel
from the battery compartment;
• remove the container in the rear
part of the trunk compartment
unscrewing its fastenings;
• remove the cap on the right-hand
side of the EPB actuator;
• insert the flexible end of the special
tool into place;

Periodic Maintenance
Every 300 mi (500 km) or before long
journeys
Check:
• engine coolant;
• windshield washer fluid level;
• tire inflation pressure and condition;• operation of lighting system
(headlights, turn signals, hazard
warning flashers, etc.);
• operation of windshield
washer/wiper system and wear of
windshield wiper blades.
Every 1900 mi (3000 km)
Check and top up, if required, the
engine oil level.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathingexhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more
information go to:
www.P65Warnings.ca.gov/passenger-
vehicle
Heavy-Duty Vehicle Use
If the car is mainly used under one of
the following conditions:
• dusty roads;
• short, repeated journeys (less than
4-5 mi/7-8 km) at sub-zero outside
temperatures;
• engine often idling or driving long
distances at low speeds or long
periods of idleness;
you should perform the following
inspections more frequently than

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 section

vehicleVehicle Stored for Long
Periods
If the vehicle is going to be stored for
over a month, follow the below
precautions:
• Wash and dry the vehicle
thoroughly.
• Store the vehicle in a covered, dry
and, if possible, ventilated area.
• Select P (Park) and turn off the
engine.
• Turn the key in the ignition switch in
STOP (OFF)position.
• Disconnect the battery (refer
“Maintenance-Free Battery” in this
section) or connect a battery charger
(refer to paragraph “Maintaining
Battery Charge” of chapter “Battery
Statement” in this section).
• Check the battery charge status.
During parking, this check must be
carried out every three weeks.
Recharge the battery if the open
circuit voltage is lower than 12.2 V.
• Check that the parking brake is NOT
engaged.
• Do not empty the engine cooling
system.
• Clean and protect the painted parts
applying protective wax.• Clean and protect polished metal
parts with special products available
on the market.
• Talc the windshield wiper blades and
raise them from the windshield.
• Cover the vehicle with a long cloth
in breathable fabric (available from
theAuthorized Maserati Dealer). Do
not use thick plastic sheets, which do
not allow the humidity on the
vehicle surface to evaporate.
• Inflate the tires up to a pressure
which must be 1 bar (14.5 psi) higher
than the normally prescribed one,
and check it at regular intervals.
NOTE:
TheAuthorized Maserati Dealercan
provide you with any information
about the available “Indoor and
Outdoor Car Covers”, available in the
“Genuine Accessories” range.
WARNING!
The tire pressure must be brought
back to the prescribed value before
reusing the vehicle (see “Tire Inflation
Pressure” in section “Features and
Specifications”).

NOTE:
•For more information about the

“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.
