Warning Lights on Speedometer
Following tell tales are displayed on
the speedometer, and related
messages are visible for 5 seconds on
sector 1 of the display, unless
otherwise indicated (see “TFT Display”
paragraph in this chapter).
Malfunction warning messages will be
stored in “Stored Messages” (see
example in picture).
Malfunction Indicator Light (MIL)
The Malfunction Indicator
Light (MIL) is part of an
onboard diagnostic system,
called OBD II, that monitors
engine and automatic transmission
control systems.
Under normal conditions, this
indicator should illuminate when the
ignition switch is in RUN position and
switch off once the engine has been
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 fuel
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 switch 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
will soon occur. Immediate service is
required. In addition, the OBDII
system incorporates a diagnostic
connector that can be interfaced
using diagnostic equipment. This
