(API). Maserati only
recommends API Certified engine oils.
CAUTION!
Do not use chemical flushes in your
engine oil as the chemicals can
damage your engine. Damage caused
by use of non-approved chemicals is
not covered by the new Vehicle
Limited Warranty.
Engine Oil Viscosity (SAE
Grade)
SAE 5W-40 engine oil is recommended
for all operating temperatures.
The engine oil filler cap also shows the
recommended engine oil viscosity for
your engine. For information on
engine oil filler cap location, refer to
chapter “Maintenance Procedures” in
section “Maintenance and Care”.
Lubricants that do not have both the
engine oil certification mark and the
correct SAE viscosity grade number
should not be used.

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

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.
