While Driving
Never travel with the tachometer
indicator approaching the peak rpm, not
even downhill. When the tachometer
indicator is approaching the peak rpm
(red colored zone), take precautions to
avoid exceeding that limit.
Specific Requirements
The following maneuvers can lead
to a temporary and/or premature
deterioration of the ignition system
with consequent lighting of the
malfunction indicator light (MIL) and
immediate request for service:
• repeated stops of the vehicle with the
engine running at idle for more than 10
minutes
• stationary vehicle with engine running
at idle for more than 1 hour
• repeated starts without reaching the
engine operating temperature (white
coolant gauge) (more than 10 starts)
• short journeys with ambient
temperatures below 32° F (0° C) or
with the engine not at operating
temperature (white coolant gauge).
To keep the combustion system at
maximum efficiency, it is advisable to
regularly follow an extra-urban route
with an average speed greater than 44
MPH (70 km/h) (in compliance with the
traffic code) for 15 minutes.
Ensure proper operation of different
devices checking their respective control
telltales.
CAUTION!
Under normal conditions, all red warning
lights on the instrument cluster display
should be off. When they come on,
they indicate a malfunction. Refer to
"Warning and Indicator Lights" in section
"Dashboard Instruments and Controls".
WARNING!
Continuing to drive when a red
warning light is on could cause serious
damage to the vehicle and affect its
performance.
On-Board Diagnostics (OBD)
Your vehicle is equipped with a
sophisticated on-board diagnostic
system. This system monitors the
Driving and Driver Assistance Systems
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
well within current local regulations of
various countries.
If any of these systems require service,
the system will turn on the
malfunction indicator light (MIL). It
will also store diagnostic codes and
other information to assist which your
Authorized Maserati Dealer will use
to service your vehicle. Although the
vehicle will still be driveable and not
need towing, contact an Authorized
Maserati Dealer for service as soon as
possible.
