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.
