Transmission Manual
Release of P (Park)
Position The manual disengagement of the
shift from P (Park) has the purpose to
allow towing the vehicle if not
normally possible using the shift lever
(such as inability to start the engine).
This procedure is exclusively intended
for emergency situations, only!
WARNING!
Always secure your vehicle by fully
applying the parking brake, before
activating the manual park release.
Activating the manual park release
could allow your vehicle to roll away
if it is not secured by the parking
brake. Activating the manual park
release on an unsecured vehicle could
lead to serious injury or death for
those in or around the vehicle.
The cover that allows the emergency
manual
park release
is located on the
left part of the driver’s foot well.
• Lift the mat on the driver side to
access the cover.
• Slip the cover from its seat. • Take strap out of its seat.
• With the tip of a screwdriver press
the clip shown in the picture box and
lift the strap up to release the
transmission from the P (Park)
position. The new position will allow
vehicle moving and towing.
• Release the parking brake only when
the vehicle is securely connected to a
tow vehicle.Auxiliary Jump-Start
Procedure If your vehicle has a discharged battery
it can be jump-started using a set of
jumper cables and a battery of another
vehicle or by using a portable battery
booster. It is necessary to have proper
jumper cables in order to connect the
booster battery to the remote posts of
the discharged battery. Booster cables
have positive and negative terminal
clamps and are identified by the
sheath color (red = positive, black =
negative).
NOTE:
An Authorized Maserati Dealer can
provide you with information about
the “Maserati Jumper Cables Kit”,
available in the “Genuine Accessories”
range.
Jump-starting can be dangerous if
done improperly so please follow the
procedures in this section carefully.
NOTE:
When using a portable battery booster
pack, follow the battery
manufacturer’s operating instructions
and precautions.In an Emergency

322

CAUTION!
• To jump start a vehicle do not use a
portable battery, a booster pack or
any other booster source with a
system voltage greater than 14 Volts
or damage to the battery, starter
motor, alternator or electrical system
of the vehicle with the discharged
battery may occur.
• Do not use a battery charger for
emergency starting under any
circumstances. You could damage
the electronic systems, particularly
the control units managing the
ignition and fuel supply functions.
• If the battery is completely
discharged when the windows are
fully raised, open the door with the
utmost care; do not close the door
again until it is possible to lower the
window.
WARNING!
Always secure your vehicle by fully
applying the parking brake, before
activating the manual park release.
Activating the manual park release
could allow your vehicle to roll away if it is not secured by the parking
brake. Activating the manual park
release on an unsecured vehicle could
lead to serious injury or death for
those in or around the vehicle.
NOTE:
If
you need
to disconnect the battery
from the vehicle electrical system, see
“Maintenance — Free Battery” in
section “Maintenance and Care”).
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
information go to: www.P65Warnings.ca.gov/passenger-

ignition switch is in the OFF position. If
this is not observed, when the ESC is
active, the ECU will store a
malfunction and the relative warning
light
will illuminate on the
instrument cluster display. This
requires the intervention of an
Authorized Maserati Dealer to reset
the system.
Towing an AWD Vehicle
WARNING!
Single axle towing or use of a tow
dolly is not allowed since it will
severely damage components of an
AWD vehicle.
WARNING!
Use of a tow dolly on front wheels is
strictly forbidden since front wheels
may still receive a residual amount of
torque and disengage the vehicle from
the tow dolly and affect safety of
both rescuers and other road users. Use the Tow Hook of the Tool
Kit CAUTION!
The tow hook should only be used for
towing the car on flat roads. Do not
use the tow hook to remove the car
that is stuck on off road stretches.
The tow hook is also used to tow the
vehicle
on the
platform of a tow truck.
The tow hook is contained in the tool
kit (see “Tool Kit” in this section) and
must be screwed in its seat accessible
behind the front grille, right-hand
side, after removing the protective
cap.
• Carefully clean the threaded seat
before screwing the hook.
• Screw the tow hook into its seat for
at least 11 turns. NOTE:
Maximum work angle of towing cable
or bar: 15°.

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.
• Overfilling the brake fluid reservoir
can result in spilling brake fluid.
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.
Adding Washer Fluid
The
reservoir on
the left side of the
engine compartment contains the
fluid to wash the windshield.
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
3.7 Quarts (3.5 litres) of washer fluid. • Remove the reservoir cap in the
engine compartment and lift the
filler neck.
• Fill the reservoir with windshield
washer solvent (refer to “Refillings”
in section “Features and
Specifications”) and operate the
system 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:
The Authorized Maserati Dealer can
provide you with information about
the Maserati recommended
“Windshield Washer Fluid” with
antifreeze, available in the “Genuine
Accessories” catalog.
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
