Defroster
Check
operation by
selecting the
defrost mode and place the fan system
on high speed (see “Air Conditioning
Controls” chapter in section
“Dashboard Instruments and
Controls”).
You should be able to feel the air
directed against the windshield and
front side windows. Contact
Authorized Maserati Dealer for service
if your defroster is inoperable.
Floor Mat
Always use floor mats designed to fit
the footwell of your vehicle. Use only
floor mats that leave the pedal area
unobstructed and that are firmly secured so that they cannot slip out of
position and interfere with the pedals
or impair safe operation of your
vehicle.
NOTE:
The Authorized Maserati Dealer can
provide you with any information
about the available Maserati floor
mats included in the “Genuine
Accessories” range.
WARNING!
Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury.
• Always make sure that floor mats
are properly attached to the proper
fasteners.
• Never place or install floor mats or
other floor coverings in the vehicle
that cannot be properly secured to
prevent them from moving and
interfering with the pedals.
• Never put floor mats or other floor
coverings on top of already installed
floor mats. Additional floor mats
and other coverings will reduce the
size of the pedal area and interfere with the pedals.
• Check mounting of mats on a
regular basis. Always properly
reinstall and secure floor mats that
have been removed for cleaning.
• Always make sure that objects
cannot fall into the driver footwell
while the vehicle is moving. Objects
can become trapped under the
brake pedal and accelerator pedal
causing a loss of vehicle control.
• Mounting posts must be properly
installed, if not equipped from the
factory. Failure to properly follow
floor mat installation or mounting
can cause interference with the
brake pedal and accelerator pedal
operation causing loss of control of
the vehicle.
Tires
•
Examine tires for excessive tread
wear and uneven wear patterns.
• Check for stones, nails, glass, or
other objects lodged in the tread or
sidewall.
• Inspect the tread for cuts and cracks.
• Inspect sidewalls for cuts, cracks and
bulges.
• Check the wheel nuts for tightness.Before Starting

Brake and Stability Control
System The vehicle is equipped with an
Electronic Stability Control System
(ESC), which helps to maintain
directional control in the event of loss
of grip of the tires. The system is able
to detect potentially dangerous
situations for the stability of the
vehicle and automatically sets the
brakes on all four wheels in a
differentiated manner, in order to
provide a torque settlement of the
vehicle.
ESC includes the following subsystems:
• ABS (Anti-lock Braking System);
• EBD (Electronic Brake-force
Distribution);
• TCS (Traction Control System);
• BAS (Brake Assist System);
• BTO (Brake Throttle Override);
• HSA (Hill Start Assist).
WARNING!
• These systems cannot prevent the
natural laws of physics from
affecting the vehicle, nor can they
increase traction, braking or steering
efficiency beyond that afforded by the condition of the vehicle brakes
and tires.
• These systems cannot prevent
collisions, including those resulting
from excessive speed in turns,
following another vehicle too
closely, or hydroplaning.
• The capabilities of a vehicle
equipped with these systems must
never be exploited in a reckless or
dangerous manner that could
jeopardize the driver’s and the
passenger’s safety or the safety of
others.
Electronic Stability Control
(ESC) This system enhances directional
control and stability of the vehicle
under various driving conditions. The
ESC corrects over steering and under
steering of the vehicle by applying the
brake to the appropriate wheel.
Engine power may also be reduced to
assist in counteracting the conditions
of instability and maintain the right
direction. The system is also able to
reduce the engine power.
Through sensors fitted on the vehicle,
the ESC system detects the driver’s
chosen direction comparing it to the
one maintained while running. In case of discrepancy between the required
trajectory and the current one, the ESC
system brakes the appropriate wheel
to counteract over or under steering.
• Oversteer - when the vehicle is
turning more than appropriate for
the steering wheel position.
• Understeer - when the vehicle is
turning less than appropriate for the
steering wheel position.
The ESC system has two available
operating modes:
ESC on
This is the normal ESC operating mode.
At each start-up of the vehicle, the ESC
system is set in this mode and should
be used for most driving conditions.
The ESC should only be turned off for
specific reasons as pointed out in the
following paragraphs.
ESC off
The “ESC off” mode is aimed for a
more spirited driving experience but
also purposeful for driving in deep
snow, sand, or gravel. The current
mode disables the TCS portion of the
ESC and raises the threshold for ESC
activation, allowing higher wheel spin
than normally granted by the ESC
system. The
(ESC OFF) button is
fitted beside the gear shift lever: toDriving

deactivate the system see “Drive
Mode” in this section.
WARNING!
In SPORT mode the ESC control
thresholds are higher for maximum
performance on dry road surface. To
ensure maximum security of the ESC,
it is recommended not to activate
SPORT mode on surfaces with
medium- and low-grip (e.g., wet,
snow, dirt, etc..) with ESC system
active (
(ESC OFF) button not
pressed).
NOTE:
• When in “ESC off” mode, the TCS
functionality of ESC is deactivated
(except for the limited slip feature
described in the TCS paragraph of
this chapter). All other stability
features of ESC function regularly.
• To improve the vehicle's traction
when driving with snow chains, or
when starting off in deep snow,
sand, or gravel, it may be desirable
to switch to the “ESC off” mode by
pressing the
(ESC OFF) button and
remain in this operational mode no
longer than needed. Once the
situation requiring “ESC off” mode is overcome, turn the ESC on again by
pressing the
(ESC OFF) button.
This may also be performed while in
motion.
Anti-Lock Braking System (ABS)
and Electronic Brake-force
Distribution (EBD) The Anti-Lock Braking System (ABS)
provides increased vehicle stability and
brake performance under most
braking conditions. The system
automatically “pumps” the brakes
during severe braking to prevent
wheel lock-up.
The Electronic Brake-force Distribution
(EBD) prevents the rear wheels from
over-braking and provides greater
control of available braking forces
applied to the rear axle.
WARNING!
The ABS helps prevent the wheels
from locking, but it does not increase
the physical grip limits between the
tires and the road. Therefore, always
keep a safe distance from the vehicle
in front of yours and reduce your
speed when entering a curve. NOTE:
• When
the vehicle's speed is higher
than 7 mph (11 km/h), you may hear
a slight clicking sound as well as
other motor noises. The system is
performing a self-check cycle to
ensure that the ABS is working
properly.
• This self-check occurs each time the
vehicle is started and accelerated
past 7 mph (11 km/h).
ABS is activated during braking under
certain road or stopping conditions.
ABS-inducing conditions can include
ice, snow, gravel, bumps, railroad
tracks, loose debris.
You may also experience the following
when the brake system goes into Anti-
Lock:
• The ABS motor running (it may
continue to run for a short time
after the vehicle stops).
• The clicking sound of solenoid
valves.
• Brake pedal pulsations.
• A slight drop or fall away of the
brake pedal at the end of the stop.
These are all normal characteristics
of ABS functioning.Driving

249

WARNING!
• The ABS contains sophisticated
electronic equipment that may be
susceptible to interference caused by
improperly installed or high output
radio transmitting equipment. This
interference can cause possible loss
of anti-lock braking capability.
Installation of such equipment
should be performed by qualified
Maserati personnel.
• Pumping the Anti-Lock Brakes will
diminish their effectiveness.
Pumping brakes makes the stopping
distance longer. Just press firmly on
your brake pedal when you need to
slow down or stop. Do not pump
brakes.
Traction Control System (TCS) The current device is an integral part
of the ESC system. It operates
automatically by reducing the power
transmitted by the engine in case of
slipping, loss of grip on wet floor
(aquaplaning), acceleration on slippery
snow-covered or frozen surfaces, etc.
Activating under slip conditions
different control systems: • if slippage affects both drive wheels,
it reduces the power transmitted by
the engine;
• if slippage only affects one drive
wheel, it brakes the slipping wheel
automatically.
Brake Assist System (BAS) This system completes the ABS system
by optimizing the vehicle braking
capacity during emergency brake
maneuvers. The system detects an
emergency braking situation by
sensing the rate and amount of brake
application and then applies optimum
pressure to the brakes in order to help
reduce braking distances.
The quick brake coupling is optimal for
BAS performances. In order to fully
exploit the system, apply continuous
brake pedal pressure during the entire
vehicle stop sequence. Do not reduce
brake pedal pressure earlier than
required. Once the brake pedal is
released, the BAS is deactivated.
Brake Throttle Override (BTO) To complete the range of systems that
assist braking, the vehicle is equipped
with BTO, which is designed to stop
the vehicle even when it is during
acceleration. If the brake pedal is
depressed together with the accelerator, the system does not
consider as “conflict” the sequence
“brake-first-then-accelerator” of pedal
application and it will not engage the
BTO. When the system recognizes that
the accelerator pedal is stuck pressed
and the sequence “accelerator-first-
then-brake-pressed” (this sequence is
recognized as a “conflict”), the engine
power should be automatically
reduced and, if the driver continues to
depress the accelerator and the brake
pedal, the system can make the vehicle
come to a complete stop.
Additionally, if the brake pedal is
released when the accelerator is still
stuck pressed, the corresponding
engine torque increases gradually to a
safe value.
During this event, the ETC light
indicator will illuminate. The system
exits from this strategy when the
accelerator pedal is completely
released.
Hill Start Assist (HSA) The HSA system is designed to assist
the driver when starting a vehicle
uphill. HSA will maintain the level of
brake pressure applied for a short
period of time also after releasing the
brake pedal.Driving

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

Department of Transportation
Uniform Tire Quality Grades The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each
category is shown on the sidewall of
the tires on your vehicle.
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:Driving
