the left turn signals or the
hazard flashers are turned on.
The indicator light will flash at
the same frequency of the turn signals
and is controlled by the left
multifunction lever.
If the vehicle electronics sense that the
vehicle drives for more than 1 mile
(1.6 km) with either turn signal on, a
continuous sound will alert the driver
to turn the signal off.
If the indicator flashes at a rapid rate,
check for a defective exterior light
bulb.
Rear Fog Light Indicator
This indicator lights up when
the rear fog lights are
switched on.
Tire Pressure Monitoring Light (*)
This indicator light is
connected to the Tire Pressure
Monitoring System (TPMS).
Under normal conditions, the
warning light should illuminate when
the key in the ignition switch is in
MAR (ON)position and should go off
as soon as the engine is started.
If the warning light remains lit or
illuminates while driving, the pressureof one or more tires is too low: the
related message will be displayed.
If the warning light flashes prior to
remain on, it indicates that the system
is temporarily unavailable.
This warning light illuminates even
when you calibrate the TPMS and
remains lit until the system is
calibrated.
Please refer to “Tire Pressure
Monitoring System (TPMS)” in section
“Driving” for further information.

All passenger car tires must conform to
Federal safety requirements in
addition to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The
relative performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AAA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING!
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
Temperature Grades
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of
the tire to degenerate and reduce tire
life, and excessive temperature can
lead to sudden tire failure. The grade
C corresponds to a level of
performance, which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No.
109. Grades B and A represent higher
levels of performance on the
laboratory test wheel, than the
minimum required by law.
WARNING!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
Tire Pressure
Proper tire inflation pressure is
essential for safety and best
performance of your vehicle. The tire
pressure monitoring system “TPMS”
setup on the vehicle (see “Tire Pressure
Monitoring System” in this section)
may alert the driver about insufficient
tire pressure even though the driver is
responsible for regularly checking the
tire pressure.
Radial tires fitted on the vehicle may
look properly inflated even when they
actually are under inflated. Do not
make a visual judgment when
determining proper inflation.
Three primary driving aspects are
affected by improper tire pressure:
Safety
Driving
5
190

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 pressureschange 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.
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.
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.
YourAuthorized Maserati Dealeris
available to provide suggestions as tothe 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 any
tire on the vehicle.

NOTE:
TheAuthorized Maserati Dealercan
provide you with all information about
the Maserati Snow Chains, available in
the "Genuine Accessories" range.Tire Pressure Monitoring
System - TPMS
Guidelines
Each tire (including the spare tire, if
provided) should be checked monthly.
Tires should be checked when cold and
inflated to the inflation pressure
recommended by the vehicle
manufacturer indicated on tire
inflation pressure label (applied on the
driver's rear door pillar) and in “Tire
Inflation Pressure” of section “Features
and Specifications”.
If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.
As an added safety feature,
your vehicle has been
equipped with a tire pressure
monitoring system (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on asignificantly under-inflated tire causes
the tire to overheat and can lead to
tire failure. Under-inflation also
reduces fuel efficiency and tire tread
life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the
malfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the vehicle
