2020 MASERATI GRANTURISMO CONVERTIBLE Owners Manual

Use the Vehicle 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 can also be used to tow
the vehicle on the platform of a tow
truck.
It is necessary to inform the operators
of the rescue vehicle about the vehicle
minimum height to avoid, during its
loading, any contact of the lower ends
of the front or rear bumper with the
tow truck loading ramp.
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.
• Remove the protective cap by
levering with the tip of a screwdriver
in the point shown in picture.• 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°.
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.

must be restarted with the operations
scheduled for the 1

replacements or repairs are found to
be necessary in addition to the
scheduled operations, these can be
carried out only with the specific

Authorized Maserati Dealerof any
minor operating problem, without
waiting for the next scheduled service.

Scheduled Maintenance
(Service) Indicator
When the deadlines for maintenance
Scheduled Maintenance services are
approaching, a message on the
instrument cluster display indicates
that service is due. The deadline may
be expressed in miles/Km or days,
whichever comes first.
The message is displayed only once,
upon activating the instrument cluster,
at decreasing intervals expressed in
mi/km (100, 50...... 1800, 1600,) or in
days (27, 24, ....... 6, 3), accompanied

Once the set limit in kilometers or the
expiry date is reached, every time the
instrument cluster is turned on
thereafter, the message “Service
coupon expired” will be displayed.Selecting the function “Service” in the
“Trip” menu of the MTC+, you can
display the next service deadline (see
“Onboard Computer (Trip)” in section
"Driving"). The residual mileage left
to the service deadline is always
indicated. The days remaining before
the scheduled service date instead, are
only indicated starting from the 511th
day (approximately 17 months).
NOTE:
Every time the battery is disconnected,
the date and time must be set (see
"MTC+ Settings" in section
"Dashboard Instruments and
Controls").
CAUTION!
• Failure to reset the system may cause
it to malfunction and indicate wrong
maintenance service intervals.
• If you incorrectly set a date earlier
than the last service coupon, the
system updates the indication
“Scheduled service within... days”
automatically entering a later date
considering the maximum number of
days allowable for the next service
coupon.
