continuous sound will advise the
driver to turn the signal off.
If the indicator flashes at a fast rate,
check for a defective outside indicator
light bulb.
Seat Belt Reminder Light
When the ignition switch is in
RUN , the seat belt reminder
light will light up for a few
seconds as a bulb check.
During the bulb check, you will hear
an acoustic signal if one or both front
seat belts are unbuckled.
After the bulb check or while driving,
if a seat belt is unbuckled, together
with the acoustic signal the seat belt
reminder light will light up and a
message will indicate which belt is not
fastened.
WARNING!
Maserati urges you to use the seat
belts correctly fastened and adjusted
at all times. Correct use of the seat
belts can help reduce the risk of
serious injury in the event of an
accident. Do not pass seat belts over
sharp edges. They could tear. Do not
pin anything to the seat belts. This
could reduce their initial strength and cause them to tear in the event of a
crash.
Refer to “Occupants Restraint
Systems”
in section
“Before Starting”
for further information.

Loading
The vehicle maximum load on the tire
must not exceed the load carrying
capacity of the tire on your vehicle.
You will not exceed the tire's load
carrying capacity if you adhere to the
loading conditions, tire size, and cold
tire inflation pressures specified on
the “Tire and Loading Information
Label” and in the “Features and
Specifications” section.
NOTE:
Under a maximum loaded vehicle
condition, gross axle weight ratings
(GAWRs) for the front and rear axles
must not be exceeded.
To determine the maximum loading
conditions of your vehicle, locate the
statement “The combined weight of
occupants and cargo should never
exceed XXX lbs/XXX kg” on the tire
and loading information label. The
combined weight of occupants and
cargo/luggage should never exceed
the weight referenced here.
Steps For Determining Correct Load
Limit
• Locate the statement “The combined
weight of occupants and cargo
should never exceed XXX
lbs/XXX kg” on the vehicle's label. • Determine the combined weight of
the driver and passengers that will
be riding in the vehicle.
• Subtract the combined weight of the
driver and passengers from
XXX lbs/XXX kg.
• The resulting figure equals the
available amount of cargo and
luggage load capacity. For example,
if “XXX amount equals
1,400 lbs/635 kg and there will be
five 150 lbs/68 kg passengers in your
vehicle, the amount of available
cargo and luggage load capacity is
650 lbs/295 kg (since 5 x 150/68 =
750/340, and 1,400/635– 750/340 =
650 lbs/295 kg).
• Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calculated
in previous Step.
• If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your
vehicle. Tires
Driving over rough or damaged road
surfaces, as well as debris, curbs and
other obstacles can cause serious
damage to wheels, tires, and
suspension parts.
This is more likely to occur with
low-profile tires, which provide less
cushioning between the wheel and
the road.
Be careful to avoid road hazards and
reduce your speed, especially if your
vehicle is equipped with low profile
tires.
WARNING!
Overloading of your tires is
dangerous. Overloading can cause tire
failure, affect vehicle handling, and
increase the stopping distance. Use
tires of the recommended load
capacity for your vehicle. Never
overload them.Driving

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
