and is controlled by the stalk switch
lever.
If the vehicle electronics sense that the
vehicle drives for more than 1.6 km
(1 mile) with either turn signal on, a
continuous sound will alert the driver
to turn the signal off.
If the indicator flashes at a rapid ratel,
check for a defective exterior light
bulb.
Tire Pressure Monitoring Light
This warning light is connected
4
to the Tire Pressure
Monitoring System (TPMS).
Under normal conditions, the
warning light should illuminate when
the ignition switch is in RUN and
should go off as soon as 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 indicator lights
up, the system may not be able to
detect or signal low tire pressure
correctly.
Please refer to "Tire Pressure
Monitoring System (TPMS)" in section
5 for further information.
Anti-Lock Brake (ABS) Light
This light, and its related
message, indicate possible
malfunctions of the Anti-Lock
Brake System (ABS).
The light will turn on when the
ignition switch is in RUN position and
may stay on for 4 seconds. If the ABS
light remains lit or turns on while
driving, the Anti-Lock portion of the
brake system is not functioning and
requires service. However, the
conventional brake system will
continue to operate normally if the
warning light is switched off. If
the ABS light turns on while driving, or
if it does not switch on when the
ignition switch is in RUN position,
please visit as soon as possible a
Maserati Service Center in order to
restore the Anti-Lock brakes functions.
Electronic Stability Control (ESC)
Activation/Malfunction Indicator Light
The ESC activation/malfunction
indicator light on the
instrument cluster will display
when the ignition switch is in
RUN position.
It should switch off by starting the
engine.
If the light stays on with the engine
running, there is a malfunction in the
ESC system.
If the light still stays on after several
ignition cycles, and the vehicle has
been driven for several kilometers at
more than 48 km/h (30 mph) speed,
visit the Maserati Service Network as
soon as possible to have the problem
diagnosed and restored.
NOTE:
Each time the ignition switch is in RUN:
• The ESC off indicator light and the
ESC activation/malfunction indicator
light illuminates temporarily.
• The ESC system will be on, even if it
was turned off previously. The ESC
system will make buzzing or clicking
sounds when active. This is normal;
the sounds will stop when ESC
becomes inactive by solving the
