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 “Dashboard Instruments 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 the Authorized 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.

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.
NOTE:
For
the tire repair procedures with tire
repair kit see instructions included in
the kit.
This kit will provide a temporary tire
seal, allowing you to drive your
vehicle up to 6 miles (10 km) with a
maximum speed of 50 mph (80 km/h).
CAUTION!
• Intruding objects (e.g., screws or
nails) should not be removed from
the tire, which could compromise
the repair with the tire repair kit.
• Do not use the tire repair kit if the
tire shows lateral damages and/or the rim is damaged by driving with
flat tire.
• Tire repair kit can be used in outside
temperatures down to
approximately -4°F (-20°C).
• Replace the tire repair kit sealant gas
cylinder prior to the expiration date
(printed on the gas cylinder label) to
assure optimum operation of the
system.
NOTE:
• The
compressor power plug can be
inserted either in the 12 V power
outlet housed in the trunk or inside
the passenger compartment (see
“Interior Features” in section
“Understanding the Vehicle”).
• When having the tire serviced,
advise the Authorized Maserati
Dealer or service center that the tire
has been sealed using the tire repair
kit.
Using the Compact Spare
Wheel (for versions/markets
where provided)
Upon request, the vehicle may come
equipped with a compact spare wheel
(emergency wheel), jack and tools for
replacing a wheel. The compact spare wheel is stored in
the trunk and is supplied deflated in
order to limit the amount of space
occupied. An electric compressor is
also provided for inflating. In the
event of a tire puncture, proceed as
follows.
• Stop the vehicle in a place that does
not constitute a danger to traffic
and where the wheel can be
changed safely. The vehicle must be
level and on firm ground.
• Select the P (Park) mode and then
engage manually the electric
parking brake and turn the key in
the ignition switch to STOP (OFF)
position.
• If necessary, turn the hazard warning
flashers on and place the warning
triangle at the required distance.
WARNING!
• The jack should be used on level
firm ground wherever possible.
• It is recommended that the wheels
of the vehicle be chocked, and that
no person should remain in a vehicle
that is being jacked.
• If the vehicle has been stopped on a

Brake Fluid Level Check
Check
the fluid level immediately if
the brake system red warning
light and the related message turn on
indicating a low level of brake fluid.
• Clean the brake fluid reservoir area
around the cap before removing it.
• Add fluid to bring the level up to the
“MAX” mark on the side of the
master cylinder reservoir. Use only
manufacturer's recommended brake
fluid (see “Refillings” in section
"Features and Specifications").
• Once the correct level is reached,
firmly close the cap.
The brake pads wear could cause the
fluid level to fall. However, low fluid
level may be caused by a leak and a requires accurate checkup of the
braking system.
CAUTION!
The symbol
on the tank cap
identifies the synthetic type of brake
fluid, distinguishing it from the
mineral type. Using mineral fluids
damages the special rubber linings of
the brake system irreparably.

WARNING!
• To avoid contamination from foreign
materials or moisture, use only new
brake fluid or fluid that has been in
a tightly closed container. Keep the
master cylinder reservoir cap secured
at all times. Brake fluid in an open
container absorbs moisture from the
air resulting in a lower boiling point.
This may cause it to boil
unexpectedly during hard or
prolonged braking, resulting in
sudden brake failure. This could
result in an accident.
• Overfilling the brake fluid reservoir
can result in spilling brake fluid on
hot engine parts, causing the brake
fluid to catch fire. Brake fluid can
also damage painted and vinyl
surfaces, make sure it does not spill
over these surfaces.
• Do not allow petroleum based fluid
to contaminate the brake fluid.
Brake seal components could be
damaged, causing partial or
complete brake failure. This could
result in an accident.Maintenance and Care

Always use washer fluid when using
the wipers to remove salt or dirt from
a dry windshield.
Avoid using the wiper blades to
remove frost or ice from the
windshield. Keep the blade rubber out
of contact with petroleum products
such as engine oil, gasoline, etc.
Spray nozzles
If the jet does not work, first check
that there is fluid in the pan (see
paragraph “Level checks” in this
section) then check that the nozzles
are not clogged.
Blades Replacement
• Move the right multifunction lever
into “OFF” position, (see chapter
“Windshield Wipers and Washers” in
section “Understanding the
Vehicle”).
• Lift the end of the arm provided with
the blade from the windshield.
• Rotate the blade on the arm in order
to access the release latch, shown in
the detail of picture.
• Press the release latch to free the
blade.
• Turn and slip off the blade from the
arm and replace it. • Return the blade to its original
position on the windshield.
NOTE:
Due to the difficulty of this operation,
we recommend that you contact an
Authorized Maserati Dealer for
replacement of the blades.
Body Lubrication
Locks and all body pivot points,
including such items as seat tracks,
door hinge pivot points and rollers,
trunk lid and hood, sliding doors and
hood hinges, should be lubricated
periodically with a lithium based
grease, to assure quiet, easy operation
and to protect against rust and wear.
Prior to the application of any
lubricant, the parts concerned should
be wiped clean to remove dust and
grit; after lubricating excess oil and grease should be removed. Particular
attention should also be given to hood
latching components to ensure proper
function. When performing other
underhood services, the hood latch,
release mechanism and safety catch
should be cleaned and lubricated. The
coupling pin of the lock on the rear
driver door pillar should be lubricated
twice a year, preferably in the Fall and
Spring. Apply a small amount of high
quality lubricant directly into the lock
cylinder.Maintenance and Care
