2020 MASERATI GRANTURISMO 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.

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.
Emergency Starting with
Maserati Code
If the Maserati CODE fails to
deactivate the engine immobilizer, the
CODE warning light will illuminate
permanently, while the
MIL
warning light will go off after four
seconds and will turn on again
immediately afterward: the engine will
not start.
To start the engine, follow the
emergency starting procedure.
Emergency Starting Procedure
NOTE:
We recommend that you carefully read
the entire procedure before
performing it. If you make a mistake,
turn the key in the ignition switch to
STOP (OFF)position and repeat the
operations from the first step.

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
information go to:
www.P65Warnings.ca.gov/passenger-
vehicle
WARNING!
•Use only refrigerants and
compressor lubricants approved by
the manufacturer for your air
conditioning system. Some
refrigerants are flammable and can
explode, causing injuries. Other
unapproved refrigerants or
lubricants can cause the system to
fail, requiring costly repairs.
•The air conditioning system contains
refrigerant under high pressure. To
avoid risk of personal injury or
damage to the system, adding
refrigerant or any repair requiring
lines to be disconnected should be
done by an experienced technician.
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.

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

• battery voltage is insufficient or
simply there is no power at the
mains socket.
Check maintainer connections (to
mains and vehicle socket) and power
availability at the mains socket; if LED
or LEDfor “Active” or
“Passive” stage does not turn on
within a few seconds from proper
maintainer connection, contact an
Authorized Maserati Dealerto have
vehicle electrical system inspected.
Precautions and Warnings
• Make sure that cables are not
pinched or reach hot surfaces or
cutting edges.
• Do not cover battery maintainer.
• Make sure that mains connector is
not exposed to water/rain.
• Connection to the mains must
comply with prevailing regulations
on high voltage.
• Always check maintainer cables
before use: make sure that cables
and external sheath are free of
cracks.
• Never use a maintainer if cables are
damaged.
• Store and use the maintainer out of
reach of children; do not allowchildren to play with the battery
charge maintainer.
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.

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.
