heated external mirrors automatically
turn off after 10 minutes.
CAUTION!
Failure to observe the following
cautions may cause damage to the rear
windows defroster:
• Use care when washing the inside of
the rear window. Do not use abrasive
window cleaners on the interior
surface of the window. Use a soft
cloth and a mild washing solution,
wiping parallel to the heating
elements. Labels can be peeled off
after soaking with warm water.
• Do not use scrapers, sharp
instruments, or abrasive window
cleaners on the interior surface of
the window.
• Keep all objects inside the vehicle at
a safe distance from the window. 11. MAX A/C
By
pressing the “MAX A/C” button or
the MTC+ soft-key, the system
automatically switches to get the
maximum cold air flow in both zones.
12 - 13. Air flow distribution modes
The airflow distribution mode,
respectively on the driver and on the
passenger zone, can be adjusted so air
comes from the dashboard vents, vents
under the dashboard in direction of
the floor, vents under the front seats
and demist/defrost vents.
The MTC+ display contains the
relevant soft-keys used to set these
modes for each zone. The climate
control panel features a single button
for each zone: press it several times to
select and set the required airflow
distribution mode.
Available settings are as follows:
• “Floor” mode
Air for each zone comes from the
front vents, located under the
dashboard and under the front
seats. A small portion of the airflow
is directed through the
defrost/demist vents to prevent
windows fogging.
• “Dashboard” mode
Air flows for each zone from four
adjustable vents of the dashboard,Dashboard Instruments and Controls

6. Synchronise the two rear
passenger temperature setting. If
the driver adjust the temperature
while SYNC mode is on, this will
affect the rear passenger
temperature. If the front or rear
passengers adjust the
temperature setting the system
automatically break the function
and turn it off.
7. Set the blower speed through
sever speed levels.
8. Re-activate the rear climate
setting.
9. Turn off the rear climate option.
10. Block the settings of the rear
climate.
11. Return to the front climate
control screen. Operating Tips • Continuous use of the air
recirculation in winter, in rainy
weather or humid climate is not
recommended because it may cause
window fogging.
• Interior fogging on the windshield
can be quickly removed by fast
defrosting/defogging. The “Mix”
mode can be used to maintain a clear
windshield and provide sufficient
heating. If side window fogging
becomes a problem increase blower
speed.
NOTE:
• Recirculation mode without A/C
should not be used for long periods
of time, as fogging may occur.
• If inside the passenger compartment
there are conditions of high
temperature and humidity, when the A/C compressor is switched on (A/C
softkey illuminated on MTC+ display
or LED on climate control panel A/C
button ON) there may be some cold
steam at ventilation port outlet: this
situation is normal and does not
indicate air conditioning system
malfunction.
• Automatic Temperature Controls
(ATC) will automatically adjust the
climate control settings to prevent or
eliminate window fogging on the
front windshield.
• Make sure the A/C system air intake
grille, located under the bonnet
directly in front of the windshield, is
free of obstructions such as leaves or
other objects. Leaves collected in the
air intake may reduce airflow, and if
they enter the plenum, they could
plug the water drains. In winter
make sure the air intake is clear of
ice, slush, and snow.
• The temperature can be displayed in
U.S. or Metric. units by selecting the
“Units” customer programmable
feature. See “MTC+ Settings” in this
section.

Normal Starting of the
Engine WARNING!
It is dangerous to run the engine in an
enclosed area. The engine consumes
oxygen and discharges carbon
dioxide, carbon monoxide and other
toxic gases in the atmosphere.
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 known 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

the
Maserati Logo in the center and the
complete odometer plus the open
doors indicator
in the lower part of
the cluster.
Before starting the engine, close the
doors, adjust your seat, the inside and
outside mirrors, fasten your seat belt
and instruct all other occupants to
buckle their seat belts.
The shift lever must be in P (Park) or N
(Neutral) position before you can start
the engine. Apply the brakes before
shifting into any driving gear (see
“Automatic Transmission” in this
section). CAUTION!
• Before starting the engine, switch off
the electrical devices with a high
power consumption (air-conditioning

NOTE:
The gearshift indicator will only work
when the transmission is set in M +/-
(Manual) mode.
Transmission Malfunction and
Overheating Conditions Transmission Emergency Control
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. In some situations, the
transmission system may not
re-engage if the engine is turned off
and restarted.
A message in the instrument cluster
will inform the driver about the more
serious transmission conditions, and
indicate what actions may be
necessary.
Transmission Oil Overtemperature
If the transmission oil temperature
exceeds the operating limit, the red
warning light
illuminates on the
instrument cluster. In this case, slow down until
temperature returns to normal level
(the light will turn off).
If this is not sufficient, we recommend
to stop the vehicle, shift the lever to
position P (Park) or N (Neutral) and
keep the engine idle until the
temperature red warning light
turns off and the message
disappears from the display. Resume
driving without demanding high
engine performance. If the red
warning light
and the related
message turns on again, it is advisable
to stop the vehicle, turn off the engine
and wait for the engine/transmission
assembly to fully cool down.
If the instrument cluster message
indicates that the transmission may
not re-engage after engine shutdown,
perform the following procedure
preferably at an Authorized Maserati
Dealer . In the event of a momentary problem,
the transmission can be reset to regain
all forward gears by performing the
following steps.
• Stop the vehicle.
• Shift the transmission into P (Park), if
possible.
• Turn the engine off.
• Wait approximately 30 seconds.
• Restart the engine.
• Shift the transmission into D (Drive)
and then into the desired gear
range. If the problem is no longer
detected, the transmission will return
to normal operation.
NOTE:
Even if the transmission can be reset,
we recommend that you visit an
Authorized Maserati Dealer at your
earliest possible convenience, which
has diagnostic equipment to
determine if the problem could recur.

All-Wheel Drive (AWD
version only) The active on-demand All-Wheel Drive
(AWD) system provides available
optimum traction for a wide variety of
road surface and driving conditions.
The system minimizes wheel slip by
automatically redirecting torque to
the front and rear wheels as necessary.
To maximise fuel economy, the AWD
system automatically disangages
torque distribution on front axle when
road and environmental conditions
are such that wheel slip is unlikely to
occur. When specific road and
environmental conditions require
increased levels of road traction, the
AWD system automatically distributes
the torque between front and rear
axle in order to grant the best driving
experience. Torque distribution is
displayed on the TFT in the “Drive
Mode” main menu. Refer to
paragraph “TFT Display: Menus and
Settings” in chapter “Instrument
Cluster” of section “Dashboard
Instruments and Controls” for further
information. WARNING!
There may be a slight delay for AWD
engagement after a wheel slip
condition occurs.
NOTE:
If the A
WD system service warning
light and message appears after
engine start up, or during driving, it
means that the AWD system is not
functioning properly or is in recovery
mode due to overheating caused by
the excessive wheel spin. In this
condition the vehicle can continue
driving but only rear wheel drive is
working. If the warning light and
message is often activated, it is
recommended to have the vehicle
serviced at an Authorized Maserati
Dealer . Driving

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, the
parking brake must not be used since
the push of the power actuator might
not be sufficient to ensure vehicle
braking, especially on a slope.
Drive normally without braking to
allow the brakes to cool down a few
minutes before stopping. The
automatic or manual activation of the
parking brake will ensure vehicle
braking.
Brake overheating could also cause
“squeals” and “vibration”. Use of the Engine Breaking-In Today's most modern production
methods are designed to provide
extremely precise construction and
assembly of components. However,
moving parts do undergo a settling
process, basically in the first hours of
vehicle operation.
Do not drive keeping at a constant
high speed rate for a prolonged time.
While cruising, brief full-throttle
acceleration within the limits of local
traffic laws contributes to a good
break-in. Wide-open throttle
acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine
at the factory is a high-quality energy
conserving type lubricant. Oil changes
should be consistent with anticipated
climate conditions under which vehicle
operations will occur. For the
recommended viscosity and quality
grades, see “Refillings” in section
“Features and Specifications”.
A new engine may consume some oil
during its first few thousand
miles/kilometers of operation. This
should be considered as a normal part of the break-in and not interpreted as
an indication of malfunction.
Specific Requirements
Avoid exceeding 5000 rpm for the first
620 mi trip (1000 km).
After starting the vehicle, do not
exceed 4000 rpm until the engine has
warmed up sufficiently (coolant
temperature: 149-158°F /65 70°).
While Driving Never travel with the tachometer
indicator approaching the peak rpm,
not even downhill. When the
tachometer indicator is approaching
the peak rpm (red colored zone), take
precautions to avoid exceeding that
limit.
Ensure proper operation of different
devices checking their respective
control telltales.Driving

Safety
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 pressures
change 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.Driving

Some advices for driving in the rain are
listed below.
• Reduce your speed and keep a
greater safety distance from the
vehicles in front of you. High speed
may result in a loss of vehicle control.
• When driving on wet or slushy roads,
it is possible for a wedge of water to
build up between the tire and road
surface. This is known as
aquaplaning and may cause partial
or complete loss of vehicle control
and stopping ability. To reduce this
possibility: slow down if the road has
standing water or puddles.
• Heavy rain substantially reduces
visibility. In these circumstances, even
during the day, turn on the low
beams, to be more visible to other
drivers.
• Set the air conditioning and heating
system controls on the defogging
function, in order to avoid any
visibility problem.
• Periodically check the conditions of
the windshield wiper blades.
• In low grip conditions use “I.C.E.”
driving mode (see chapters “Drive
Mode” in this section). • Avoid driving with ESC OFF as this
will likely cause a loss of control of
the vehicle.
Driving in Fog
If the fog is dense, avoid traveling if
possible.
When driving in mist, blanket fog or
when there is the possibility of banks
of fog, please consider some advices
listed below.
• Keep a moderate speed.
• Even in daytime, turn on the low
beams and rear fog lights. Do not
use the high beams.
• Remember that fog creates
dampness on the asphalt and thus
any type of maneuver is more
difficult and braking distances are
extended.
• Keep a safe distance from the vehicle
in front of you.
• Avoid sudden changes in speed as
much as possible.
• Whenever possible, avoid overtaking.
• If you are forced to stop the vehicle
(breakdowns, impossibility of
proceeding due to poor visibility,
etc.), first of all, try to stop off of the
travel lane. Then turn on the hazard
warning flashers and, if possible, the
low beams. CAUTION!
Be aware that rear fog lights can
bother the drivers following your
vehicle: when visibility is back to
normal, turn off these lights.
Driving in the Mountains
Mountain
roads usually
have many
narrow turns and curves, tunnels and
steep uphill or downhill slopes: please
consider some advices listed below.
• Drive at a moderate speed, avoid
“cutting” corners.
• When driving inside a tunnel in
daylight turn on the low beams in
advance; avoid high beams and be
aware of the rapid brightness
change. Avoid abrupt maneuvers
that could be dangerous for the
following vehicle.
• Never coast downhill with the engine
off or in neutral.
• 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

Engine Air Filters Replacement Contact an Authorized Maserati
Dealer to have the air filters replaced.
A/C Air Filter Replacement This filter performs mechanic/
electrostatic air filtering, provided that
windows and doors are closed.
The filter is located under the hood in
the external A/C system air inlet, on
the passenger side of the vehicle, next
to the windshield wipers.
To replace the filter during the
scheduled maintenance services or
after the vehicle has been heavily used
on dusty roads, proceed as follows:
• Remove the access door in the cowl
screen by pressing the retaining clips
indicated. • Unsnap both ends and lift the filter
retaining cover.
• Remove the used filter slipping it off
from within the air intake.
• Install the new filter with arrows
pointing in the direction of airflow,
which is toward the rear of the
vehicle (text and arrows on the filter
will indicate this). • Close the filter retaining cover and
reinstall the access door.
CAUTION!
Failure to replace the filter may
considerably reduce the air
conditioning and heating system
efficiency.
Wiper Maintenance and Blades
Replacement Windshield Wiper Arms Lifting
When the windshield wiper arms are
in rest position it is not possible to
check or replace the blades as they
remain under the engine hood.
To service the blades it is necessary to
move the wiper arms in “Service”
position (see chapter “Wipers and
Washers” in section “Understanding
the Vehicle”). In this way it is possibleMaintenance and Care

Insufficient tire inflating pressure can
cause tire overheating and possible
internal damage.
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
technician, 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 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
should always be observed, also in
case of “nondirectional” tires.
• Check the depth of the tire tread at
regular intervals. 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 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.
The Authorized Maserati Dealer can
provide all necessary information
about fitting winter tires on the
vehicle.
NOTE:
• We recommend fitting winter tires
on the vehicle at temperatures
below 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.Maintenance and Care
