the efficiency of engine braking
together with the standard braking
system.
ESC System Operations
In order to prevent unstable driving
conditions, the ESC system may request
the transmission system to deactivate
gearshifting. The system handles this
request depending on the gear
engaged and on the rpm, and decides
whether to accept it or not.
Driving with Cruise Control
With the Cruise Control function
activated, the transmission system
selects such settings as to provide
enhanced comfort and fuel-economy.
MC Start Strategy (for MC version
only)
With the aim of optimizing standing
starts for performance driving (only
recommended for use in areas closed
to traffic and in accordance with the
Highway Code), the automatic
transmission system is equipped with
quick start strategy.
This strategy is activated when the
following conditions occur
simultaneously:
• AUTO and SPORT modes active;
•
ESC mode off;
• brake pedal depressed.In these conditions, the driver has the
possibility to accelerate and, keeping
the brake pedal depressed, keep the
vehicle standing until reaching an
engine speed between 2300 an 2500
rpm. Then, upon releasing the brake
pedal, have the best standing start
performance.
WARNING!
This strategy must only be used on
vehicles in areas closed to traffic, in
accordance with the Highway Code
and only by skilled drivers.
Transmission Malfunction and
Overheating Conditions
Transmission Failure
Transmission function is electronically
monitored to detect abnormal
conditions. If a condition that could
result in transmission damage is
detected, Transmission Limp Home
Mode will be activated. In this
situation, the transmission may
operate only in certain gears, or may
not shift at all.
CAUTION!
In these conditions, we recommendedthat you stop the vehicle and turn off
the engine for at least one minute.
When restarting the engine, the
self-diagnosis system may cancel the
malfunction, which will in any case be
recorded by the ECU.
A message and thewarning light
in the instrument cluster will inform
the driver about the transmission
failure.
In failure conditions, the transmission
shift lever can however be shifted to R
(Reverse), N (Neutral) and D (Drive)
position.
When shifting to D (Drive) position,
only a few gears will be available,
depending on the malfunction found.
CAUTION!
If a transmission failure is signaled,
take your vehicle to the nearest
Authorized Maserati Dealeras soon as
possible to have the problem
corrected.
If the failure is signaled when the
engine is started, it means that the
transmission ECU detected a fault
when the vehicle was last used. Also in
this case, take your vehicle to the
nearest Center of theAuthorized

brake fluid level immediately (see
"Maintenance Procedure" in section
“Maintenance and Care”). If fluid is
below the minimum level, top up
with the recommended fluid and
contact an Authorized Maserati
Dealer immediately to have the
system checked. Brake fluid leaks
affect the operation of the braking
systems.
•The brake system performance in
terms of active safety is not a reason
for the driver to run unnecessary
risks. The driving style shall always
be suited to weather conditions,
range of visibility and traffic.
•The maximum deceleration that can
be obtained always depends on the
tire grip on the road surface. With
snow or ice on the road the grip is
obviously reduced and the braking
distance is very high, even with the
ABS system.
Brake Pads and Brake Discs
Wear on the brake pads and brake
discs depends to a great extent on the
driving style and the conditions of use
and therefore cannot be expressed in
actual kilometers driven on the road.The high-performance brake system is
designed for optimal braking effect at
all speeds and temperatures.
Certain speeds, braking forces and
ambient conditions (e.g. temperature,
humidity and long outdoor stopping
periods) can therefore cause the
brakes to "squeal". This is normal and
will cease after a few brakings.
New Brake Pads and/or Brake
Discs
New brake pads have to be “broken
in”, and therefore only attain optimal
friction to the brake disc when the
vehicle has covered several
hundreds km.
During this first period, the slightly
reduced braking ability must be
compensated for by pressing the brake
pedal harder. This applies whenever
the brake pads and/or brake discs are
replaced.
Brake Overheating
Driving on mountain roads with steep
slopes or a sports use of the vehicle
could overheat the brake system
components. In these conditions,
parking brake must not be used since
the push on the brake shoes of the
power actuator might not be sufficientto ensure vehicle braking, especially on
a slope.
Drive normally without braking to
allow the brakes to cool down a few
minutes before stopping. In this way,
the automatic or manual activation of
the parking brake will ensure vehicle
braking.

•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 whenchecking 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.

Engine Overheating
To reduce potentially overheating of
the engine in city traffic, while
stationary, place the transmission in N
(Neutral), but do not increase the
engine idle speed.
NOTE:
There are steps that you can take to
slow down an impending overheat
condition:
•If your air conditioner (A/C) is on,
turn it off. The A/C system adds heat
to the engine cooling system and
turning the A/C off can help remove
this heat.
•You can also turn the temperature
control to maximum heat, the mode
control to floor and the blower
control to high. This allows the
heater core to act as a supplement to
the radiator and aids in removing
heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system
could damage the engine. If the
temperature gauge is positioned on
the red zone (refer to “Instrument
Cluster” in section “DashboardInstruments and Controls”), pull over
and stop the vehicle. Idle the vehicle
with the air conditioner turned off
until the temperature gauge drops
back into the normal range. If the
temperature gauge remains on the red
zone turn the engine off immediately
and contact theAuthorized Maserati
Dealer.
WARNING!
You or others can be badly burned by
hot engine coolant (antifreeze) or
steam from your radiator. If you see or
hear steam coming from under the
hood, do not open it until the radiator
has had time to cool.
Never try to open a coolant bottle
pressure cap (refer to “Maintenance
Procedures” in section “Maintenance
and Care”) when the radiator is
overheated.
In case of a Punctured Tire
The vehicle can be equipped with a
tire repair kit or with a compact spare
wheel.
Using Tire Repair Kit
Small punctures up to 1⁄4” (6 mm) in
the tire tread can be sealed using the
tire repair kit, fitted beneath the floor
panel of the trunk compartment.
The kit comes in a bag and consists of
two parts:
• an electric compressor with pressure
gage, hose to be connected to the
punctured tire and power cable;
• a gas cylinder containing sealant.

Freeing the Stuck Vehicle
If your vehicle is stuck in mud, sand, or
snow, it can probably be moved
backward and forward by a simple
rocking motion.
Steer the wheel right and left to clear
the area around the front wheels.
Shift then between D (Drive) or
MANUAL mode and R (Reverse) (see
chapter “Automatic Transmission” and
“Drive Mode” in section “Driving”).
Shifting to MANUAL mode, try to free
the car starting in second gear.
At low speed motion of the vehicle,
you can switch quickly from D (Drive)
to R (Reverse), and vice versa, just by
pressing the release button on the
shift lever.
For more effectiveness press lightly on
the accelerator pedal in order to avoid
wheel slippage.
If unable to release the vehicle in one
of the previously described ways, enter
the low-grip driving mode, by pressing
the “ICE” button, and completely
exclude the yaw and slip control
system, by pressing the
(ESC Off)
button for at least 2 seconds. Moving
the shift lever between D (Drive) and R
(Reverse) to start.
CAUTION!
Racing the engine or spinning the
drive wheels may lead to transmission
overheating and failure. Allow the
engine to idle with the shift lever in N
(Neutral) for at least one minute after
every five rocking-motion cycles. This
will minimize overheating and reduce
the risk of transmission failure during
prolonged efforts to free a stuck
vehicle.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive drive
wheel speeds may cause damage, or
even failure, of the drivetrain and
tires.
Emergency Starting with
Maserati Code
If the Maserati CODE fails to
deactivate the engine immobilizer, the
CODE warning light will illuminate
permanently, while the
MIL
warning light will go off after four
seconds and will turn on again
immediately afterward: the engine will
not start.
To start the engine, follow the
emergency starting procedure.
Emergency Starting Procedure
NOTE:
We recommend that you carefully read
the entire procedure before
performing it. If you make a mistake,
turn the key in the ignition switch to
STOP (OFF)position and repeat the
operations from the first step.

Wheels Maintenance
Tires Maintenance
CAUTION!
To obtain the best performances and
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
Specifications”) and should be checked
only when the tires have cooled down.
In fact, the pressure increases as the
tire temperature progressively
increases.
Never reduce the pressure if tires are
hot (see “Tires – General Information”
chapter in section “Driving”).Insufficient tire inflating pressure can
cause tire overheating and possible
internal damage, which may even lead
to the tire destruction.
CAUTION!
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 it.
Impacts with curbs, holes, and
obstacles in the road, and prolonged
trips on rough roads can cause tire
damage which may not be visible to
the naked eye.
Check your tires regularly for any signs
of damage (e.g. scratches, cuts, cracks,
bulges, etc.). If sharp objects penetrate
the tires, they can cause structural
damage which is only visible when the
tire is removed.
In any case, any possible damage must
be inspected by an experienced tire
fitter, as it may seriously reduce the
tire life.
Remember that tires deteriorate with
time, even if used little or not at all.
Cracks in the tire tread and sides,
alongside possible bulging, are a sign
of deterioration.
WARNING!
•Check the inflating pressure of the
tires when cold, at least every two
weeks and before long trips.
•Have the old tires inspected by an
experienced technician, to make sure
they can still be used safely. If the
same tire has been on your vehicle
for 4 or 5 years, have it inspected
anyway by an experienced
technician.
•Never fit tires of uncertain origin.
•“Directional” tires have an arrow on
their side showing the rolling
direction. To keep the best
performance when replacing a tire,
make sure that the rolling direction
corresponds to the one shown by
the arrow.
•During the tire life, the rolling
direction used for the first fitting
shall always be observed, also in
case of “nondirectional” tires.
•Check the depth of the tire tread at
regular intervals. The minimum
allowed value is 0.06 in (1,6 mm) at
that point the wear indicators on the
tire will be visible (see “Tires –
General Information” in section
