Warning and Indicator Lights
on Analog Instruments Telltales on Speedometer
The following telltales are displayed
on the speedometer, and related
messages are visible for 5 seconds on
the central sector of the display, unless
otherwise indicated (see “TFT Display”
paragraph in this chapter).
Malfunction Indicator Light (MIL)
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 ignition switch is in RUN position
and switch off soon after the engine is
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 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

Electric Power Steering Failure
Warning Light
This warning light, and the
related message, illuminate
when the electric power
steering is not operating and
needs service.
If the warning light is on, steering
assistance may be not available.
WARNING!
After battery disconnection event, the
warning light may be on. In this case,
start the engine and perform a
steering wheel stroke end to end.
If the problem persists, contact an
Authorized
Maserati Dealer .
Catalyst Over Temperature Warning
Light
This warning light, and the
related message, light up if
the engine runs irregularly
with consequent high
temperature in the exhaust system. WARNING!
• If the warning light is accompanied
by the message “Catalyst Temp
Getting Hot Reduce Speed”: the
temperature of the catalytic
converters is too high. The driver
must slow down immediately until
the warning light turns off.
• If the message “Catalyst Temp Hot
Stop Safely Wait To Cool” appears
after decelerating: the temperature
in the catalytic converters has
reached a dangerous level and the
catalytic converters could be
damaged. Drive slowly to the
nearest Authorized Maserati Dealer.
• Maserati declines all responsibility
for whatever damage deriving from
non-compliance with the above
mentioned warnings.
Door Ajar Indicator
This
indicator illuminates
when
one or more doors are
ajar. The indicator will show
which door is ajar. When one
or more doors are open, a related
message will be displayed if the vehicle
is running at a speed of 5 mph
(8 km/h) or faster. Trunk Lid and Hood Ajar Indicators
These light indicators will
illuminate to indicate that the
trunk lid and/or the hood are
ajar.
When the trunk lid or the
hood is open, a related
message will be displayed
besides the light if the vehicle is
running at a speed of 5 mph (8 km/h)
or faster.
Electronic Throttle Control (ETC)
Indicator
This indicator light indicates a
failure of the Electronic
Throttle Control (ETC) system.
If the indicator turns on while
driving (a torque decrease is possible),
have the system checked by an
Authorized Maserati Dealer .
When detecting a failure, the light
indicator will illuminate while the
engine is running.
If the indicator remains lit with the
engine running, you can still drive your
vehicle. However, contact an
Authorized Maserati Dealer as soon as
possible.
If the indicator is flashing while the
engine is running, immediate service is
required. You may experience reduced
performance, an elevated/rough idleDashboard Instruments and Controls

CAUTION!
• Under normal conditions, all red
warning lights on the instrument
cluster display should be off. When
they come on, this indicates a
malfunction. Refer to “Instrument
Cluster” in section “Dashboard
Instruments and Controls”.
• Continuing to drive when a red
warning light is on could cause
serious damage to the vehicle and
affect its performance.
Onboard Diagnostic System Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the
performance of the emissions, engine,
and automatic transmission control
systems. When these systems are
operating properly, your vehicle will
provide excellent performance and
fuel economy, as well as engine
emissions well within current local
regulations of various countries.
If any of these systems require service,
the system will turn on the
Malfunction Indicator Light (MIL).
It will also store diagnostic codes and
other information, which your Authorized Maserati Dealer will use to
service your vehicle. Although the
vehicle will still be driveable and not
need towing, contact an Authorized
Maserati Dealer for service as soon as
possible.
CAUTION!
• Prolonged driving with the
Malfunction Indicator Light
(MIL) on could cause further damage
to the emissions control system. It
could also affect fuel economy and
drivability. The vehicle must be
serviced before any emissions tests
can be performed.
•Ifthe
Malfunction Indicator
Light (MIL) is flashing while the
engine is running, severe catalytic
converter damage and power loss will soon occur. Immediate service is
required at an Authorized Maserati
Dealer .
• After the problem has been solved,
the Authorized Maserati Dealer
personnel will perform specific tests
for a complete check of the system
and, if necessary, road tests.Driving

CAUTION!
• Maserati strongly recommends the
use of Premium unleaded fuel ONLY.
Use of lesser grade fuel (other than
Premium) will lead to reduced
engine performance, and poor fuel
economy and can lead to the
Malfunction Indicator Light
illuminating on the instrument
cluster. Continued use of lesser grade
fuel (other than Premium fuel) can
lead to engine misfire problems and
possible catalytic converter damage.
• The anti-pollution devices of the
vehicle require unleaded fuel to be
used at all times. Under no
circumstance, not even in an
emergency, should leaded fuel be
supplied to the fuel tank, not even a
minimum quantity. This would
irreparably damage the catalytic
converters. An inefficient catalytic
converter results in noxious exhaust
emissions which damage the
environment.
Reformulated Gasoline Many areas of the country require the
use of cleaner burning gasoline,
referred to as “Reformulated Gasoline”. Reformulated gasoline
contains oxygenates and are
specifically blended to reduce vehicle
emissions and improve air quality.
Maserati supports the use of
reformulated gasoline. Properly
blended reformulated gasoline will
provide excellent performance and
durability of engine and fuel system
components.
Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded
gasoline with oxygenates such as
Ethanol. Fuels blended with
oxygenates may be used in your
vehicle.
CAUTION!
DO NOT use gasoline containing
Methanol or gasoline containing more
than 10% Ethanol. Use of these blends
may result in starting and driveability
problems, damage critical fuel system
components, cause emissions to
exceed the applicable standard, and/or
cause the Malfunction Indicator Light
to illuminate (see “Instrument
Cluster” in section “Dashboard
Instruments and Controls”. Pump
labels should clearly communicate if a
fuel contains greater than 10% Ethanol.
Problems that result from using
gasoline
containing Methanol or
gasoline containing more than 10%
Ethanol are not the responsibility of
Maserati and may not be covered
under warranty.
MMT in Gasoline MMT (Methylcyclopentadienyl
Manganese Tricarbonyl) is a
manganese containing metallic
additive that is blended into some
gasoline to increase octane.
Gasoline blended with MMT provides
no performance advantage beyond
gasoline of the same octane number
without MMT.
Maserati recommends gasoline
without MMT to be used in your
vehicle. The MMT content of gasoline
may not be indicated on the gasoline
pump; therefore, you should ask the
gasoline station operator whether or
not the gasoline contains MMT.
It is even more important to look for
gasoline without MMT in Canada,
because MMT can be used at levels
higher than those allowed in the
United States. MMT is prohibited in
Federal and California reformulated
gasoline.Driving

• short, repeated journeys (less than
4–5 mi/7-8 km) at sub-zero outside
temperatures;
• engine often idling or driving long
distances at low speeds or long
periods of idleness;
you should perform the following
inspections more frequently than
recommended on the “Scheduled
Service Plan”:
• check front disc brake pad conditions
and wear;
• check cleanliness of hood and trunk
locks, cleanliness and lubrication of
linkage;
• visually inspect conditions of: engine,
transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (boots - sleeves -
bushes - etc.);
• check battery charge;
• visually inspect condition of the
accessory drive belts;
• check and, if necessary, change
engine oil and replace oil filter;
• check and, if necessary, replace
pollen filter of the A/C system;
• check and, if necessary, replace air
cleaner filter. CAUTION!
All maintenance operations for the
vehicle must be carried out by an
Authorized Maserati Dealer . For
routine and minor maintenance
operations which you can carry out
yourself, make sure that you have the
necessary experience and always use
suitable equipment, original Maserati
spare parts and the prescribed fluids.
Shall this not be the case, do not carry
any operation on your own and
contact an Authorized Maserati
Dealer .
On Board Diagnostic System Your vehicle is equipped with a
sophisticated on board diagnostic
system called OBD II. This system
monitors the performance of the
emissions, engine, and automatic
transmission control systems. When
these systems are operating properly,
your vehicle will provide excellent
performance and fuel economy, as
well as engine emissions suited to
current government regulations.
If any of these systems require service,
the OBD II system will turn on the
Malfunction Indicator Light
on the
instrument cluster display (refer to “Instrument Cluster” in section
“Dashboard Instruments and
Controls”). The system stores as well
diagnostic codes and other
information to assist your service
technician by performing repairs.
Although the vehicle will be driveable
and will not need towing, contact an
Authorized Maserati Dealer for service
as soon as possible.
CAUTION!
• Prolonged driving with the MIL
on could cause further damage to
the emissions control system. It could
also affect fuel economy and
driveability. The vehicle must be
serviced before any emissions tests
can be performed.
• If the MIL
is flashing while the
engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate service at
an Authorized Maserati Dealer is
required.
