Safety
WARNING!
• Improperly inflated tires can be
dangerous.
• Under-inflation increases tire flexing
and can result in tire overheating.
• Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and potholes can cause
damage that results in tire failure.
• Over-inflated or under-inflated tires
can affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause
steering problems.
• 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.
Economy
Improper
inflation pressures may
cause uneven wear patterns to
develop across the tire tread. These
abnormal wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-
inflation also increases tire rolling
resistance resulting in higher fuel
consumption.
Ride comfort and vehicle stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Pressure Checkup The proper cold tire inflation pressure
is indicated on the driver's side rear
door pillar and on the table “Tire
Inflation Pressure” in section
“Features and Specifications”.
Inflation pressure specified on the
table always refers to “cold tire
inflation pressure”. Cold tire inflation
pressure is defined as the tire pressure
after the vehicle has not been driven
for at least three hours, or driven less
than 1 mi (1.6 km) after a three hour
period.
Check tire pressures more often in
case of significant outside
temperature changes, as tire pressure
varies according to temperature
changes.
The pressure should be checked and if
necessary adjusted; tire wear and overall conditions should also be
checked monthly. Tire pressures
change by approximately 1 PSI (0.07
bar) per 12°F (7°C) of air temperature
change. Keep this in mind when
checking tire pressure inside a garage,
especially in winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 PSI
(0.21 bar) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6
PSI (0.13 to 0.4 bar) during operation.
DO NOT reduce this normal pressure
build-up or your tire pressure will be
too low. 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 the
valve stem and the TPMS sensor
connected to it.
Tread Wear Indicators Tread wear indicators are in the
original equipment tires to help you
determine when your tires should be
replaced.
These indicators are molded into the
bottom of the tread grooves.Driving

297

When the tread is worn to one of the
tread wear indicators, the tire should
be replaced.
WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning could
result in tire failure. Replacement Tires NOTE:
In order to maintain high performance
and safety level under all driving
conditions, Maserati strongly
recommends to use tires equivalent to
the originals in size, quality and
performance when replacement is
needed.
For the size designation of your tire
see the label on the driver's side rear
door pillar or see table “Wheels” in
section “Features and Specifications”.
The “Load Index” and “Speed Symbol”
for your tire will be found on the
original equipment tire sidewall.
NOTE:
Maserati recommends Maserati
Genuine Tires marked with “MGT”
logo specifically designed for its
models.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling.
If you ever replace a wheel assembly,
make sure that the wheel’s
specifications (valve, TPMS sensor and
tire) match those of the original
wheels. Failure to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Your Authorized Maserati Dealer is
available to provide suggestions as to
the types of tires most suited to the
use foreseen by the Customer.
WARNING!
• Do not use a tire, wheel size or
rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and
performance characteristics,
resulting in altered steering,
handling, and braking operations of
the vehicle. This can cause
unpredictable handling and stress to
steering and suspension
components. Use only the tire and
wheel sizes with load ratings
appointed for your vehicle.
• Never use a tire with a smaller load
index or capacity, other than what
was originally equipped on your
vehicle. Using a tire with a smaller
load index could result in tire
overloading and failure.
• Always check the maximum speed
rating on the tire sidewall on anyDriving

Driving Conditions Before the Trip Check the following at regular
intervals and always before long trips:
• tire pressure and condition;
• levels of fluids and lubricants;
• conditions of the windshield wiper
blades;
• clean the glass on the external light
and all other glass surfaces;
• proper operation of the indicator
lights and of the external lights.
CAUTION!
It is however advisable to perform
these checks at least every 600 mi
(1000 km) and always following the
maintenance schedule reported in
section “Maintenance and Care”.
Before you drive:
•
adjust seat position, steering wheel,
adjustable pedals (if equipped with)
and rearview mirrors in order to
have the best driving position;
• ensure that nothing (mat covers,
etc.) is obstructing the pedals
movement; • carefully arrange and secure any
objects in the trunk, to prevent them
from moving forward in case of
sudden stops;
• avoid heavy meals before a trip. A
light snack helps keep your reflexes
sharp. In particular, avoid drinking
alcohol.
WARNING!
Passengers must only travel seated in
the vehicle seats, with the seat belts
fastened. Always check that the driver
and all passengers have the seat belts
correctly fastened.
Safe Driving Although the vehicle is equipped with
active and passive safety devices, the
driver's conduct is always a decisive
factor for road safety.
Some simple rules for traveling safely
in different conditions are listed
below. Some of them will probably
already sound familiar but, in any
case, it would be useful to read them
carefully.
Driving at Night
The main guidelines to follow when
driving at night are set out below. • Drive carefully. Night conditions
demand more focus and attention.
• Reduce your speed, especially on
roads with no streetlights.
• Stop at early signs of drowsiness.
Continuing to drive would be a risk
for yourself and for others. Have a
rest before continuing your trip.
• Keep the vehicle at a greater
distance from vehicles in front of
you than you would during the day:
it is difficult to assess the speed of
other vehicles when you only see the
lights.
• Use the high beams only outside of
densely-populated areas and when
you are sure that they will not
disturb other drivers.
• When another vehicle is
approaching, switch from high
beams (if on) to low beams.
• Keep lights and headlights clean.
• Outside of densely-populated areas,
beware of animals crossing the road.
Driving in the Rain
Rain and wet roads are dangerous. On
a wet road all maneuvers are more
difficult since wheel grip on the road
is significantly reduced. This means
that braking distances increase
considerably and road grip decreases.Driving

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
