Warning and Indicator Lights
on Analog Instruments
Low Fuel Indicator on Fuel Gage
The illumination of the red indicator
inside the gage indicates that there
are approx. 4.7 Gallons (18 liters) of
fuel in the tank.
If the pointer positions on "0"
(beginning of scale) and the fuel
reserve indicator flashes, it means that
there is a system malfunction.
In this case, contact anAuthorized
Maserati Dealerto have the system
checked.
Telltales on Speedometer
Following telltales are displayed on
the fuel level gage and speedometer,
and related messages are visible for 10
seconds on the central sector of the
display, unless otherwise indicated.The telltales indicated with (*) are also
displayed on the TFT display (see “TFT
Display” paragraph in this chapter).
Charging System Warning Light
This warning light shows the
status of the electrical
charging system. If the light
stays on or comes on while
driving, turn off some of the vehicle's
non-essential electrical devices or
increase engine speed (if at idle). If
the charging system warning light
remains on, it means that the vehicle
is experiencing a problem with the
charging system. Require IMMEDIATE
service at anAuthorized Maserati
Dealer.
If jump starting is required, refer to
“Jump Start Procedures” in section “In
an Emergency”.Malfunction Indicator Light (*)
The Malfunction Indicator
Light (MIL) is part of an
onboard diagnostic system
that monitors engine and
automatic transmission control
systems.
Under normal conditions, this
indicator light should switch on when
the key in the ignition switch is in
MAR (ON)position and switch off
soon after the engine is started.
This is a sign of the indicator light
working properly. If the indicator
remains lighted up 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.
Under these conditions you can
proceed slowly without forcing the
engine or driving at high speeds.
The indicator light will switch off if
the problem is solved.
The error will be registered by the
system in any case.
