2020 MASERATI GRANTURISMO CONVERTIBLE heating

Engine Overheating
To reduce potentially overheating of
the engine in city traffic, while
stationary, place the transmission in N
(Neutral), but do not increase the
engine idle speed.
NOTE:
There are steps that you can take to
slow down an impending overheat
condition:
•If your air conditioner (A/C) is on,
turn it off. The A/C system adds heat
to the engine cooling system and
turning the A/C off can help remove
this heat.
•You can also turn the temperature
control to maximum heat, the mode
control to floor and the blower
control to high. This allows the
heater core to act as a supplement to
the radiator and aids in removing
heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system
could damage the engine. If the
temperature gauge is positioned on
the red zone (refer to “Instrument
Cluster” in section “DashboardInstruments and Controls”), pull over
and stop the vehicle. Idle the vehicle
with the air conditioner turned off
until the temperature gauge drops
back into the normal range. If the
temperature gauge remains on the red
zone turn the engine off immediately
and contact theAuthorized Maserati
Dealer.
WARNING!
You or others can be badly burned by
hot engine coolant (antifreeze) or
steam from your radiator. If you see or
hear steam coming from under the
hood, do not open it until the radiator
has had time to cool.
Never try to open a coolant bottle
pressure cap (refer to “Maintenance
Procedures” in section “Maintenance
and Care”) when the radiator is
overheated.
In case of a Punctured Tire
The vehicle can be equipped with a
tire repair kit or with a compact spare
wheel.
Using Tire Repair Kit
Small punctures up to 1⁄4” (6 mm) in
the tire tread can be sealed using the
tire repair kit, fitted beneath the floor
panel of the trunk compartment.
The kit comes in a bag and consists of
two parts:
• an electric compressor with pressure
gage, hose to be connected to the
punctured tire and power cable;
• a gas cylinder containing sealant.
In an Emergency
6
214

• Remove the screwdriver from the
hole, being careful not to move the
transmission shift lever.
• Shift the lever fully into N (Neutral).
This position will allow vehicle
towing.
• Reinstall all the removed electrical
parts pushing it in the central
console seat until you hear the
locking click.
• Reinstall the covering panel on the
external side of the central console
press it until all pins are engaged in
their clips and “click” in place.
CAUTION!
Work extremely carefully so as not to
damage the central console trim
panels.
Freeing the Stuck Vehicle
If your vehicle is stuck in mud, sand, or
snow, it can probably be moved
backward and forward by a simple
rocking motion.
Steer the wheel right and left to clear
the area around the front wheels.
Shift then between D (Drive) or
MANUAL mode and R (Reverse) (see
chapter “Automatic Transmission” and
“Drive Mode” in section “Driving”).
Shifting to MANUAL mode, try to free
the car starting in second gear.
At low speed motion of the vehicle,
you can switch quickly from D (Drive)
to R (Reverse), and vice versa, just by
pressing the release button on the
shift lever.
For more effectiveness press lightly on
the accelerator pedal in order to avoid
wheel slippage.
If unable to release the vehicle in one
of the previously described ways,
enter the low-grip driving mode, by
pressing the “ICE” button, and
completely exclude the yaw and slip
control system, by pressing the
(ESC
Off) button for at least 2 seconds.
Moving the shift lever between D
(Drive) and R (Reverse) to start.
CAUTION!
Racing the engine or spinning the
drive wheels may lead to transmission
overheating and failure. Allow the
engine to idle with the shift lever in N
(Neutral) for at least one minute after
every five rocking-motion cycles. This
will minimize overheating and reduce
the risk of transmission failure during
prolonged efforts to free a stuck
vehicle.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive drive
wheel speeds may cause damage, or
even failure, of the drivetrain and
tires.

Periodically remove any leaves and
insects that may build up and obstruct
the inlet of external air in the air
conditioning system through the grille
present underneath the rear part of
the hood.
To access the grille, lift the hood as
described in “Open and Close the
Hood” in section “Before Starting”.
A/C Air Filter Replacement
This filter performs mechanic/
electrostatic air filtering, provided
that windows and doors are perfectly
closed.
Have your filter replaced at least once
a year at anAuthorized Maserati
Dealer, preferably at the beginning of
the summer period.
If the vehicle is mainly used in the city
traffic, on highways or dusty roads, we
recommend that you replace the
filters more frequently than prescribed
in the "Scheduled Service Plan" of this
section.
CAUTION!
Failure to replace the filter may
considerably reduce the air
conditioning and heating system
efficiency.
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 breathing
exhaust, 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

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”).
Maintenance and Care
7
263

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.

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.
