started (the MIL does not shut off
immediately).
This is a sign of the indicator light
working properly. If the indicator
remains lit or switches on while
driving, there is a failure in the fuel
supply/ignition and emission control
systems.
The failure could cause high exhaust
emissions, loss of performance,
poor vehicle handling and high
consumption levels.
Should this occur, proceed with
caution to your Authorized Maserati
Dealer without heavy throttle
application or driving at high speeds.
Obey all applicable local traffic
regulations.
The indicator light will go out if the
problem is no longer present. The
error will be registered by the system
in any case.
CAUTION!
• When the ignition device is in the
RUN position and if the indicator
light does not switch on or if it
switches on while driving, contact an
Authorized Maserati Dealer as soon
as possible.
•
Prolonged driving with the MIL on
could cause damage to the engine
control system. It also could affect
fuel economy and drivability. If
the MIL is flashing, severe catalytic
converter damage and power loss
may occur. Immediate service is
required. In addition, the On-
Board Diagnostics (OBDII) system
incorporates a diagnostic connector
that can be interfaced using
diagnostic equipment. This makes
it possible to read the error codes
stored in the control unit, together
with a set of specific parameters for
the engine operation diagnostic
cycle, for compliance with CARB &
EPA OBDII regulations.
Left Turn Signal Indicator Light
This indicator lights up when
the left turn signals or the
hazard flashers are turned on.
The indicator light will flash at
the same frequency of the turn signals
and is controlled by the stalk switch
lever.
If the vehicle electronics sense that the
vehicle drives for more than 1 mile
(1.6 km) with either turn signal on, a
continuous sound will alert the driver
to turn the signal off.
Dashboard Instruments and Controls
If the indicator flashes at a fast rate,
check for a defective exterior light
LED.
Tire Pressure Monitoring Light
This warning light is connected
to the Tire Pressure Monitoring
System (TPMS).
Under normal conditions,
the warning light should illuminate
when the ignition device is in RUN
and should go off once the engine is
started.
If the warning light remains lit or
illuminates while driving, the pressure
of one or more tires is too low and a
message will be displayed.
The TPMS malfunction indicator is
connected to the low tire pressure
monitoring light.
When the system detects a
malfunction, the monitoring light
and the related message will flash for
approximately one minute and then
remain lit.
This sequence will continue upon
subsequent vehicle startups as long as
the malfunction lasts.
When the malfunction warning lights
up, the system may not be able to
detect or signal low tire pressure
correctly.
