2020 MASERATI GRANTURISMO spare wheel

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;

Wheels
NOTE:
In order to maintain high performance
and safety level, Maserati
recommends to use tires equivalent to
the original size.
WARNING!
•The maximum speed reachable with
the tires (including winter tires) is
indicated by the tire manufacturer.
Always comply with the regulations
in force in the Country you are
driving in.
•Never exceed the maximum speed
indicated for the tires (including
winter tires): failure to respect the
max. speed may damage these tires.
Danger: risk of accident!
CAUTION!
• While respecting the specified sizes,
for the safe operation of the vehicle
it is also essential that it is equipped
with the same brand and type of
tires on all wheels.
• Do not use an inner tube with
Tubeless tires.

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.
