Fuel Cut-out Inertia Switch
The vehicle is equipped with a safety
switch which activates in the event of
a collision, cutting off the fuel supply
and consequently causing the engine
to stop. It also prevents fuel spreading
if the fuel lines are damaged during
the accident.
Activation of the safety switch is
signaled by the illumination of the
warning light on the instrument
cluster display.
The switch is positioned underneath
the driver seat.
In order to operate the inertia switch,
lift the seat in the highest position.
WARNING!
After a collision, if you smell fuel or
note any leakage from the fuel supply
system, do not reactivate the switch in
order to prevent any fire risks.
The activation of the inertia switch
causes all the doors and the trunk lid
to unlock, the lighting of the internal
domelight and the hazard warning
flashers.

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 arequires 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.

Adding Windshield/Headlight Washer
Fluid
The reservoir on the left side of the
engine compartment contains the
fluid to wash the windshield and
headlights.
During scheduled services or when the
message of low level of the washer
fluid appears together with the
related telltale add more fluid as
soon as possible.
The fluid reservoir may contain nearly
1.58 US gallons (6 liters) of
windshield/headlight washer fluid.
• Remove the reservoir cap in the
engine compartment and lift the
filler neck extension.
• Fill the reservoir with windshield
washer solvent (refer to “Refillings”
in section "Features and
Specifications") and operate thesystem for a few seconds to flush out
the residual water.
• When refilling the washer fluid
reservoir, apply some washer fluid to
a cloth or towel and wipe the wiper
blades clean. This will help blade
performance.
To prevent freeze-up of your
windshield washer system in cold
weather, select a solution or mixture
that meets or exceeds the
temperature range of your climate.
This rating information can be found
on most washer fluid containers.
NOTE:
TheAuthorized Maserati Dealercan
provide you with information about
the “Maserati recommended
Windshield Washer Fluid” with
antifreeze, available in the “Genuine
Accessories” range.
WARNING!
•Commercially available windshield
washer solvents are flammable.
They could ignite and burn you.
Care must be exercised when filling
or when working around the
windshield/headlight washer
system.•Do not drive with the windshield/
headlight washer reservoir empty:
the action of the washer is essential
for improving visibility when
driving.

level of the power steering reservoir.
• To carry out the check, unscrew the
cap, clean the dipstick with a dry and
clean cloth.
• Retighten the cap then unscrew it
again and check the level: it should
match the “MAX” notch marked on
the dipstick. In hot oil conditions,the level may even exceed the
“MAX” notch.
• If necessary, top up with fluid
making sure that it has the same
characteristics as the one already
used in the system (refer to
“Refillings” in section “Features and
Specifications”).
CAUTION!
Make sure that the power steering
fluid does not come in touch with the
engine hot parts as it is flammable.
Engine Air Filter Replacement

Dealerto have the air filters replaced.
Wiper Maintenance and Blades
Replacement
WARNING!
It is dangerous to operate or service
the wiper blades with the wipers in
an active position (right multifunction
lever in any position different than
“OFF”) and with the key in the
ignition switch in the MAR (ON)
position. The rain sensors may
suddenly activate the wipers.
Windshield Wiper Maintenance
Life expectancy of wiper blades varies
depending on the geographical area’s
weather conditions where the car is
used and frequency of use. Poor
performance of blades may be present
with chattering, marks, water lines or
wet spots. If any of these conditions
are present, clean the wiper blades or
replace if necessary.
Clean the rubber edges of the wiper
blades and the windshield periodically
with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove
accumulations of salt or road film.
Operation of the wipers on dry glass
for long periods may cause
deterioration of the wiper blades.

Useful Advice to Extend
Battery Life
When parking the vehicle, make sure
that the doors, front, rear lids and
flaps are properly closed. All interior
lights should be off.
When the engine is turned off, do not
keep the connected devices switched
on for a long time (such as radio,
hazard warning flashers, fan, etc.).
CAUTION!
If the battery charge remains below
50% for a long period of time, it will
be damaged due to sulfation; its
performance and starting power will
be reduced and it will be more subject
to freezing (this can happen even at
14°F/-10°C).
We recommend you to have the
battery charge condition checked,
preferably at the beginning of the
cold season, to prevent the electrolyte
from freezing.
This check should be carried out more
frequently if the vehicle is used mainly
for short trips or if it is equipped with
power absorbing devices that remain
permanently on even when the
ignition switch is off. This appliesabove all if these devices have been
retrofitted ("Aftermarket" services).
If the vehicle is not used for long
periods of time, please see “Vehicle
Stored for Long Periods” in this
section.
Battery Recharge
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
flammable gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times.
•Before using a charger device
always check that this tool is
suitable for the installed battery,
with constant voltage (lower than
14.8 V) and low amperage
(maximum limit 15 A).
•Recharge the battery in a
well-ventilated environment.
•Never charge or recharge a frozen
battery: it can explode due to
hydrogen trapped inside the ice
crystals.
•Ensure that any sparks or open
