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

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.

When adding engine coolant
(antifreeze) use pure water only, such
as distilled or deionized water when
mixing the water/engine coolant
(antifreeze) solution. The use of
impure water will reduce the amount
of corrosion protection in the engine
cooling system.
• Mix a minimum solution of 50%
engine coolant (antifreeze) and
distilled water. Use higher
concentrations (do not exceed 70%)
if temperatures below -35°F (-37°C)
are forecast.
Please note that it is the owner's
responsibility to maintain the proper
level of protection against freezing
according to the temperatures
occurring in the circulation area of the
vehicle.
The coolant tank provides a quick
visual method to determine that the
coolant level is adequate. As long as
the engine operating temperature is
satisfactory, the coolant bottle only
needs to be checked once a month.
With the engine off and cold, the level
of the coolant in the tank on the right
side of the engine compartment
should be between the MIN or MAX
reference notches indicated on the
tank.• When additional engine coolant
(antifreeze) is needed to maintain
the proper level, it should be added
to the coolant bottle after removing
the cap. Do not overfill.
• Once the desired level is reached,
reassemble and firmly close cap of
the tank.
• If frequent engine coolant
(antifreeze) additions are required,
or if the level in the coolant recovery
tank does not drop when the engine
cools, the cooling system should be
pressure-tested for leaks by aService
Center
• Keep the front of the radiator and
the condenser clean.
WARNING!
•Never add engine coolant
(antifreeze) when the engine is hot.Do not loosen or remove the cap of
the engine coolant bottle to cool a
hot engine. Heat causes pressure to
build up in the cooling system. To
prevent scalding or injury, do not
remove the pressure cap while the
system is hot or under pressure.
•When adding coolant do not use a
pressure cap other than the one
specified for your vehicle. Personal
injury or engine damage may result.
