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.

CAUTION!
• When the key on the key in the
ignition switch is in theMAR (ON)
position and if the indicator light
does not switch on or if it switches
on while driving, contact an
Authorized Maserati Dealeras 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.
Parking Lights Indicator
With the key removed from
the ignition switch, it indicates
that the parking lights are on.
Transmission Failure Warning Light (*)
Depending on the message
displayed it signals:
• a transmission failure. If the

down until the temperature goes
down to the normal values for use
(the warning light goes off).
For further information see chapter
“Automatic Transmission” in section
“Driving”.
CAUTION!
Continuous driving with the
transmission temperature warning
light illuminated will eventually cause
severe transmission damage or failure.
WARNING!

too low. The warning light is combined
with a displayed message. In this case,
turn the engine off immediately and
carry out the necessary checks.
Do not operate the vehicle until the
problem has been solved. This light
does not indicate the oil level. The
