2019 MASERATI GRANTURISMO CONVERTIBLE lock

you should perform the following
inspections more frequently than
recommended on the “Scheduled
Service Plan”:
• check front disc brake pad conditionsand wear;
• check cleanliness of hood and trunk locks, cleanliness and lubrication of
linkage;
• visually inspect conditions of: engine, transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (trunks - sleeves -
bushes - etc.);
• check battery charge;
• visually inspect condition of the accessory drive belts;
• check and, if necessary, change engine oil and replace oil filter;
• check and, if necessary, replace pollen filter of the A/C system;
• check and, if necessary, replace air cleaner filter.
CAUTION!
All maintenance operations for the
vehicle must be carried out by the
Authorized Maserati Dealer . For
routine and minor maintenance
operations which you can carry out yourself, make sure that you have the
necessary experience and always use
suitable equipment, original
Maserati
spare parts (or equivalent) and the
prescribed fluids. Shall this not be the
case, do not carry any operation on
your own and contact an Authorized
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 Dealer
for 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
the Authorized Maserati Dealer is
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.

Always use washer fluid when using
the wipers to remove salt or dirt from
a dry windshield.
Avoid using the wiper blades to
remove frost or ice from the
windshield. Keep the blade rubber out
of contact with petroleum products
such as engine oil, gasoline, etc.
Spray nozzles
If the jet does not work, first check
that there is fluid in the pan (see
paragraph “Level checks” in this
section) then check that the nozzles
are not clogged.
Blades Replacement
• Move the right multifunction leverinto “OFF” position, (see chapter
“Windshield Wipers and Washers” in
section “Understanding the
Vehicle”).
• Lift the end of the arm provided with the blade from the windshield.
• Rotate the blade on the arm in order to access the release latch, shown in
the detail of picture.
• Press the release latch to free the blade.
• Turn and slip off the blade from the arm and replace it. • Return the blade to its original
position on the windshield.
NOTE:
Due to the difficulty of this operation,
we recommend that you contact an
Authorized Maserati Dealer for
replacement of the blades.
Body Lubrication
Locks and all body pivot points,
including such items as seat tracks,
door hinge pivot points and rollers,
trunk lid and hood, sliding doors and
hood hinges, should be lubricated
periodically with a lithium based
grease, to assure quiet, easy operation
and to protect against rust and wear.
Prior to the application of any
lubricant, the parts concerned should
be wiped clean to remove dust and
grit; after lubricating excess oil and grease should be removed. Particular
attention should also be given to hood
latching components to ensure proper
function. When performing other
underhood services, the hood latch,
release mechanism and safety catch
should be cleaned and lubricated. The
coupling pin of the lock on the rear
driver door pillar should be lubricated
twice a year, preferably in the Fall and
Spring. Apply a small amount of high
quality lubricant directly into the lock
cylinder.

quick coupling from the negative
pole (–) of the battery.
If the battery needs to be removed
from
its compartment, you must first
detach the terminal clamp from
negative pole (–) and then the other
terminal clamp from positive pole (+),
after removing the protective cover.
Battery poles are marked positive (+)
and negative (–) and are identified on
the battery case.
Remove the metal clamp indicated in
the picture and then remove the
battery from the trunk compartment.
To Reconnect the Battery
NOTE:
When the battery cables have been
disconnected and the trunk lid has
been locked, it is necessary to pull the
emergency release cable in order to
re-open it. To access the trunk and
operate the emergency release (see
“Open and Close the Trunk Lid”
chapter in section “Before Starting”).
CAUTION!
• It is essential when replacing the cables on the battery that the
positive cable is precisely attached to
the positive pole (+) and the
negative cable is attached to the
negative pole (–).
• Cable clamps should be tight on the terminal poles and free of corrosion.
After the battery has been
disconnected
and re-connected and
before starting the engine it is
necessary to proceed as follows:
• Unlock and lock the doors using the radio control buttons on the key.
• Unlock the trunk lid with the radio control button on the key and then
lock it manually. • Check the seats are working
correctly: in the event of
malfunction, carry out the
initialization operations described in
the chapter “Front Seats” of the
section “Understanding the Vehicle”.
• Initialize the climate control system by activating the compressor as
described in chapter "Air
Conditioning Controls" of the section
“Dashboard Instruments and
Controls”.
• Turn on the MTC+ and set the date and time (see “MTC+ Setting” in
section “Dashboard Instruments and
Controls”).
• Lift, release and lift again the lever located next the shift lever to
initialize the electric parking brakes.
In this way the
warning light
on the instrument cluster will turn
off.
CAUTION!
• Every time the battery is reconnected, wait at least 30 seconds
with the key in the ignition switch
turned to MAR (ON) position before
starting the engine, in order to allow
the electronic system that manages
the motor-driven throttles to run a
