Towing a Disabled Vehicle
Proper towing or lifting equipment is
required to prevent damage to your
vehicle. Use only towing bars and
other equipment designed for the
purpose, following equipment
manufacturer’s instructions.
Safety chains are mandatory.
Except for the front threaded seat to
fix the supplied hook (see “Tool Kit”
chapter in this section), the vehicle is
not equipped with other connection
points for towing operations with tow
truck.
CAUTION!
Any improper maneuver and use of
unsuitable equipment for recovering
vehicle in an emergency from off road
location could seriously damage the
vehicle. Contact theAuthorized
Maserati Dealeror anyone having
suitable equipment and the required
expertise to safely and properly carry
out any required operations.
Make sure you comply with local
towing regulations.
•If the vehicle's battery is discharged,
it is necessary to shift the automatic
transmission out of the P (Park)Position and release the parking
brake (see “ Transmission Manual
Release of P (Park) position” and
“Emergency Release of the Parking
Brake” in this section).
•If the vehicle battery is still charged,
turn off the engine and disengage
the parking brake manually (if
automatically engaged) by using the
command at the side of the
transmission shift lever (see “Parking
Brake” chapter in section “Driving”).
Shift then manually the transmission
out of P (Park) as described in
“Transmission Manual Release of P
(Park) Position” chapter of this
section. If you need to use the
accessories (wipers, defrosters, etc.)
while being towed, the key in the
ignition switch must be turned in
MAR (ON)position, do not use the
ACCposition.
Vehicle Towing Conditions
Maserati only allows vehicle towing
either on a flatbed or with all four
wheels off the ground.
If flatbed equipment is not available,
and the transmission is still operable,
the vehicle may be flat towed (with all
four wheels on the ground) under the
following conditions.• The shift lever must be in N (Neutral).
• The distance to be traveled must not
exceed 30 mi (50 km ).
• The towing speed must not exceed
30 mph (50 km/h).
If the transmission is not operable, or
the vehicle must be towed faster than
30 mph (50 km/h ) or farther than 30
mi (50 km) (for example on a
highway), tow with the rear driving
wheels off the ground and on a
platform of a rescue vehicle, or with
the rear wheels raised using a wheel
lift.
CAUTION!
If you have to tow the vehicle with 2
wheels raised, ensure that the key in
the ignition switch is in theSTOP (OFF)
position. If this is not observed, when
the ESC is active, the ECU will store a
malfunction and the relative indicator
light
will illuminate on the
instrument cluster display. This
requires the intervention of an
Authorized Maserati Dealerto reset
the system.

inspections more frequently than
recommended on the “Scheduled
Service Plan”:
• check front disc brake pad conditions
and wear;
• check cleanliness of hood and trunk
locks, cleanliness and lubrication of
linkage;
• visually inspect conditions of: engine,

routine and minor maintenance
operations which you can carry outyourself, make sure that you have the
necessary experience and always use
suitable equipment, originalMaserati
spare parts (or equivalent) and the
prescribed fluids. Shall this not be the
case, do not carry any operation on
your own and contact anAuthorized
Maserati Dealer.
Onboard Diagnostic System
Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the
performance of the emissions, engine,
and automatic transmission control
systems. When these systems are
operating properly, your vehicle will
provide excellent performance and
fuel economy, as well as engine
emissions suited to current
government regulations.
If any of these systems require service,
the system will turn on the
Malfunction Indicator Light on the
instrument cluster display (refer to
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”). The system stores as well
diagnostic codes and other
information to assist your service
technician by performing repairs.Although the vehicle will be driveable
and will not need towing, contact an
Authorized Maserati Dealerfor service
as soon as possible.
CAUTION!
• Prolonged driving with the
MIL
on could cause further damage to
the emissions control system. It could
also affect fuel economy and
drivability. The vehicle must be
serviced before any emissions tests
can be performed.
•Ifthe
MIL is flashing while the
engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate service at
theAuthorized Maserati Dealeris
required.
Spare Parts
Use of genuine parts for normal or
scheduled maintenance and repairs is
highly recommended to ensure
excellent performance.
Damage or failures caused by
non-genuine spare parts used for
maintenance and repairs will not be
covered by the manufacturer's
warranty.
