or more tires falls below the
low-pressure alarm threshold (Soft
Warning). The tire with its low
pressure value will be highlighted in
amber color for 30 seconds.
• The tire with its low pressure value
in amber color, the message “Low
inflation pressure tire” and "Do not
drive on" in rolling mode with the
amber warning light always on
activates when the pressure of one
or more tires is below the minimum
pressure alarm threshold (Hard
Warning).The TPMS screen page is displayed for
30 seconds and then the screen page
that was previously displayed
reappears. If the malfunction persists,
the TPMS screen page shown in the
picture will be automatically displayed
for 30 seconds the next time the
engine is started.
The driver can call up the TPMS screen
page at any time to display which tires
have low pressure.
Occasionally, the system may not
detect which wheel signals a
malfunction. If this is the case, then
only the message “Check tire
pressure” will be displayed on the TFT
display.
Punctured Tire
When the instrument cluster receives a
signal from the tire pressure ECU
indicating that the pressure level of
one or more tires is below the alarmthreshold or there is a sudden pressure
loss (punctured tire). The
amber
warning light will permanently
illuminate on the instrument cluster
and screen pages shown in the picture
will alternate on the display for 30
seconds: then the screen page that
was previously displayed reappears on
the TFT display.
If the malfunction persists, the display
will show these screen pages for 30
seconds every time the key in the
ignition switch is subsequently turned
back toMAR (ON)position.
These screen pages will be displayed
until the situation is corrected and the
system is calibrated again as required
by the system.
System Not Calibrated
The system must be calibrated:
• after replacing one or more tires;
Driving

• after inverting the wheels;
• if you are not sure whether at least
one of the operations above was
performed.
If you simply corrected the tire
inflation pressure, you do not need to
recalibrate the system.
In the event that the system has not
been calibrated or calibration has been
performed incorrectly and following
replacement or reversal of one or
more tires, the
amber warning light
will flash for 85 seconds on instrument
cluster, and the TFT display will show
screen page with dashes “--,--” in the
place of the pressure levels of each
tire.
When the TPMS display cycle ends (30
seconds), the car symbol with message
will disappear and reappears the
screen page that was previously
displayed will reappear: the
amberwarning light remains on until the
system has been calibrated.
To calibrate the system, select the
screen page “TPMS calibration” by
pressing the “MODE” button. A
message will tell you to press and hold
button “+” to activate the calibration
procedure.
NOTE:
The TPMS calibration operation is
possible even with the engine running
but the vehicle must be stationary
(0 mph-km/h).The system may take up to 10 minutes,
by driving at speed lying between
6 mph (10 km/h) and 80 mph
(130 km/h), to complete the process.
During this time the
amber symbol
and the message “Calibration
activated” will be displayed for 10
seconds.
During calibration, if the user recalls
the information page showing the
pressure levels of each tire, dashes

with the key removed to the ignition
switch.
• Remember that passing other
vehicles when driving uphill is slower
and thus requires more free distance
on the road. If you are being
overtaken on a hill, slow down and
allow the other vehicle to pass.
Driving on Snow or Ice
Please consider some general advice
for driving in these conditions, listed
below.
• Maintain a very moderate speed.
• Fit snow chains or specific tires if the
road is covered with snow: see the
paragraphs “Tires – General
Information” in this section.
• We recommend you to activate the
“ICE” drive mode (see chapters
“Drive Mode” in this section).
• During the winter season, even
apparently dry roads can have icy
sections. Be careful when crossing
bridges, viaducts and roads that have
little exposure to the sun and are
bordered by trees and rocks. They
may be icy.
• Keep an ample safe distance from
the vehicles in front of you.
• Avoid sharp braking, sharp changes
in direction and rapid acceleration.Rapid acceleration on snow covered
or icy surfaces may cause the driving
wheels to pull erratically to the right
or left. This phenomenon occurs
when there is a difference in the
surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces
is dangerous. Unequal traction can
cause sudden pulling of the rear
driving wheels. You could lose control
of the vehicle and possibly have a
collision. Accelerate slowly and
carefully whenever there is likely to be
poor traction (ice, snow, wet mud,
loose sand, etc.).
Driving through Flooded
Sections
Driving through more than a
centimeters deep shallow standing
water section will require extra
caution to ensure passenger safety and
prevent damage to your vehicle.
WARNING!
Do not drive on or across a road or
path where water is flowing and/or
rising (as in storm run-off). Flowing
water can wear away the road or path
surface and cause your vehicle to sink
into deeper water. Furthermore,
flowing and/or rising water can carry
your vehicle away swiftly. Failure to
follow this warning may result in
injuries that are serious or fatal to
you, your passengers, and others
around you.
Although your vehicle is capable of
driving through shallow standing
water, consider the following Caution
and Warning before doing so.
CAUTION!
• Always check the depth of the
standing water before driving
through it. Never drive through
standing water that is deeper than
the bottom of the tire rims mounted
on the vehicle.
• Determine the condition of the road
or the path that is under water and if
there are any obstacles in the way

emergency starting, only use an
auxiliary battery.
• While driving, if the engine does not
run smoothly, you may continue
driving but reducing engine
performance to a minimum; you
should then contact theAuthorized
Maserati Dealeras soon as possible.
• Never run the engine, even if only
for testing, with one or more spark
plugs disconnected.
• Do not warm up the engine letting it
idle before starting off, except in the
event that the external temperature
is very low and, even then, for no
longer than 30 seconds.
Catalytic Converter Warnings
During normal operation the catalytic
converter produces high temperatures.
Failure to comply with following rules
can create fire hazards.
• Do not park the vehicle on
flammable materials (e.g. grass, dry
leaves, pine needles, etc.).
• Do not install heat guards and do
not remove those already fitted to
the catalytic converter and to the
exhaust manifold.
• Do not spray anything on the
catalytic converter, Oxygen sensor
and exhaust manifold.In addition to the catalytic converter
system, the vehicles are equipped with
a system for controlling fuel vapor
emissions. This system, called ORVR,
has been designed to help reduce
atmospheric pollution by the
evaporation from the fuel system
during the refueling process. Also,
specific to these vehicles is the fuel
filler neck which comes equipped with
a sealed plug that is grounded to
avoid possible sparking during
re-fueling.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more
information go to:www.P65Warnings.ca.gov/passenger-
vehicle
Other Tips
• Do not warm up the engine when
the vehicle is stationary: in these
conditions the engine heats up much
more slowly, thus increasing fuel
consumption and emissions. It is
advisable to move off slowly,
avoiding high engine rpm.
• As soon as traffic conditions and the
route permit it, use a higher gear.
• Avoid depressing the accelerator
repeatedly during stops at traffic
lights or before turning off the
engine.
• Keep your speed as regular as
possible, avoiding unnecessary
braking and acceleration, which
cause fuel wastage and strongly
increase exhaust emissions.
• Turn the engine off if the vehicle
remains stationary for a long time.
• Check the tire pressure regularly: if
the pressure is too low, fuel
consumption increases and the tires
are damaged.
• Do not transport unnecessary heavy
objects in the trunk compartment.
Driving

• Remove the screwdriver from the
hole, being careful not to move the
transmission shift lever.
• Shift the lever fully into N (Neutral).
This position will allow vehicle
towing.
• Reinstall all the removed electrical
parts pushing it in the central
console seat until you hear the
locking click.
• Reinstall the covering panel on the
external side of the central console
press it until all pins are engaged in
their clips and “click” in place.
CAUTION!
Work extremely carefully so as not to
damage the central console trim
panels.
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.

Periodically remove any leaves and
insects that may build up and obstruct
the inlet of external air in the air
conditioning system through the grille
present underneath the rear part of
the hood.
To access the grille, lift the hood as
described in “Open and Close the
Hood” in section “Before Starting”.
A/C Air Filter Replacement
This filter performs mechanic/
electrostatic air filtering, provided
that windows and doors are perfectly
closed.
Have your filter replaced at least once
a year at anAuthorized Maserati
Dealer, preferably at the beginning of
the summer period.
If the vehicle is mainly used in the city
traffic, on highways or dusty roads, we
recommend that you replace the
filters more frequently than prescribed
in the "Scheduled Service Plan" of this
section.
CAUTION!
Failure to replace the filter may
considerably reduce the air
conditioning and heating system
efficiency.

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”).
Maintenance and Care
7
263

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“Driving”). The thinner is the tread,
the greater is the risk of skidding.
•Drive carefully on wet roads to
decrease the risk of aquaplaning.
Winter Tires
These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle.
The features of these tires are
significantly reduced in winter when
tread depth is less than 0.157 in (4
mm). In this case, they should be
replaced.
The specific features of the winter tires
lead to lower performance under
normal environmental conditions or
on long highway trips, compared to
the standard tires.
Therefore, their use should be limited
to the situations and performance for
which they have been type-approved.
TheAuthorized Maserati Dealercan
provide all necessary information
about fitting winter tires on the
vehicle.
Maintenance and Care

264

NOTE:
•We recommend fitting winter tires
on the vehicle at temperatures 45 °F
(7 °C) since the driving performance
of summer tires is reduced at low
temperatures. Summer tires may be
permanently damaged at extremely
low temperatures.
•Comply with all state and local laws
governing snow tire and tread depth
requirements.
Wheel Rims Maintenance
All wheel trims should be cleaned
regularly with a mild soap and water.
To remove heavy soil and/or excessive
brake dust, use a nonabrasive,
non-acidic cleaner.
Do not use scouring pads, steel wool,
a bristle brush, or metal polishes.
Do not use oven cleaner that may
affect and damage the brake calipers.
Avoid automatic car washes that use
acidic solutions or harsh brushes that
may damage the wheel rim protective
finish.
Bodywork Maintenance
and Care
Protection from Atmospheric
Agents
The main causes of corrosion are:
• atmospheric pollution;
• salinity and humidity in the
atmosphere (marine areas or a damp
climate);
• seasonal environmental conditions;
• salt scattered on the roadbed to
melt ice and snow.
The abrasive action of wind-carried
atmospheric dust and sand, mud and
stones should not be underestimated.
On this vehicle, Maserati has adopted
the best technological solutions to
protect the bodywork from corrosion.
The main measures are:
• paint products and systems that give
the vehicle particular resistance to
corrosion and abrasion;
• use of galvanized (or pre-treated)
metal sheets which are highly
resistant to corrosion in the most
exposed parts;
• spraying of the underbody, engine
compartment, insides of wheel
housings, and other structures withwax products having high protective
power;
• spraying of plastic materials, with a
protective function, in the most
exposed points: underneath the
doors, inside part of the mud guards,
edges, etc.;
• use of ventilated box sections,
coated with protective wax products,
to avoid condensation and trapped
water which could encourage the
formation of internal rust.
Useful Advice to Keep the
Bodywork in Good Condition
Paint
The paintwork does not only have an
aesthetic function but also protects
the underlying metal sheets. In the
event of abrasions or deep scratches,
we recommend to have the necessary
touch-ups made immediately, to avoid
any rust formation. Touch-ups do not
feature particular difficulties, even on
metallic finishes.
For all paint touch-ups, use only
original products indicated on the
plate applied inside the hood.
