Driving
On-Board 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 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
Service Center will use to service
your vehicle. Although the vehicle
will still be driveable and not need
towing, contact the
Service Network
for service as soon as possible.
CAUTION!
•
Prolonged driving with the
Malfunction Indicator Light (MIL) on
could cause further damage to the
emissions control system. It could also
affect fuel economy and driveability.
The vehicle must be serviced before
any emissions tests can be performed.
•
If the Malfunction Indicator
Light (MIL) is flashing while the
engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate service is
required at the
Service Network .
•
After the problem has been solved,
the
Service Network personnel will
perform specific tests on the test
bench for a complete check of the
system and, if necessary, also road
tests, even on long distances.
Regenerate the Diesel
Particulate Filter (DPF)
Under conditions of exclusive short
duration and low speed driving cycles,
the engine and exhaust aftertreatment
system may never reach the conditions
required to remove the trapped
Particulate Matter (PM). This
conditions is reported by the messages
on TFT display. To restore the exhaust
aftertreatment system to normal
operating condition it is necessary to
regenerate the DPF by following the
indications reported in the paragraph
"TFT Display: Warning/Indicator
Lights of Set Modes/Functions" of
the chapter "Instrument Cluster" in
section “Dashboard Instruments and
Controls”.
CAUTION!
•
Prolonged driving with the MIL on
inhibits the regeneration process
with possible DPF clogged.
• Maserati is not responsible for
defects occurring due to not
performed DPF regeneration process.
Gasoline Particulate Filter (GPF)
(for versions/markets where
provided)
To reduce the emissions of particulate
matter, the exhaust system is equipped
with a particulate filter optimized
for the back pressure and with a high
filtration efficiency.
This filter is maintenance-free and
self-regulating and therefore does
not require a regeneration procedure
when using the car. This performance
made possible by the improvement of
the filtering support between engine
and silencer.
