2020 MASERATI GRANTURISMO check engine light

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 Dealerwill use to
service your vehicle. Although the
vehicle will still be driveable and not
need towing, contact theAuthorized
Maserati Dealerfor 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 anAuthorized Maserati
Dealer.
• After the problem has been solved,
theAuthorized Maserati Dealer
personnel will perform specific tests
on the test bench for a complete
check of the system and, if necessary,
also road tests, even on long
distances.
In addition, the system is equipped
with a diagnostics connector that,
when interfaced with suitable
instruments, makes it possible to read
the error codes stored in the ECU,
together with a set of specific
parameters for engine operationdiagnostics cycle, on compliance with
CARB, EPA OBDII rules.
CAUTION!
• Once the engine is started, the
Malfunction Indicator Light (MIL)
will remain on for approximately 18
seconds before turning off. This is a
normal condition and part of the
operating strategy.
• When the key in the ignition switch
is turned toMAR (ON)position if the
Malfunction Indicator Light (MIL)
does not illuminate or if it
illuminates while driving, contact
your localAuthorized Maserati
Dealeras soon as possible.

or more tires falls below the
low-pressure alarm threshold (Soft
Warning). The tire with its low
pressure value will be highlighted in
amber color for 30 seconds.
• The tire with its low pressure value
in amber color, the message “Low
inflation pressure tire” and "Do not
drive on" in rolling mode with the
amber warning light always on
activates when the pressure of one
or more tires is below the minimum
pressure alarm threshold (Hard
Warning).The TPMS screen page is displayed for
30 seconds and then the screen page
that was previously displayed
reappears. If the malfunction persists,
the TPMS screen page shown in the
picture will be automatically displayed
for 30 seconds the next time the
engine is started.
The driver can call up the TPMS screen
page at any time to display which tires
have low pressure.
Occasionally, the system may not
detect which wheel signals a
malfunction. If this is the case, then
only the message “Check tire
pressure” will be displayed on the TFT
display.
Punctured Tire
When the instrument cluster receives a
signal from the tire pressure ECU
indicating that the pressure level of
one or more tires is below the alarmthreshold or there is a sudden pressure
loss (punctured tire). The
amber
warning light will permanently
illuminate on the instrument cluster
and screen pages shown in the picture
will alternate on the display for 30
seconds: then the screen page that
was previously displayed reappears on
the TFT display.
If the malfunction persists, the display
will show these screen pages for 30
seconds every time the key in the
ignition switch is subsequently turned
back toMAR (ON)position.
These screen pages will be displayed
until the situation is corrected and the
system is calibrated again as required
by the system.
System Not Calibrated
The system must be calibrated:
• after replacing one or more tires;

asphalt is significantly reduced. This
means that braking distances increase
considerably and road grip decreases.
Some advices for driving in the rain
are listed below.
• Reduce your speed and keep a
greater safety distance from the
vehicles in front of you. High speed
may result in a loss of vehicle
control.
• When driving on wet or slushy roads,
it is possible for a wedge of water to
build up between the tire and road
surface. This is known as
aquaplaning and may cause partial
or complete loss of vehicle control
and stopping ability. To reduce this
possibility: slow down if the road has
standing water or puddles.
• Heavy rain substantially reduces
visibility. In these circumstances, even
during the day, turn on the low
beams, to be more visible to other
drivers.
• Set the air conditioning and heating
system controls on the defogging
function, in order to avoid any
visibility problem.
• Periodically check the conditions of
the windshield wiper blades.• In low grip conditions use “ICE”
drive mode (see chapters “Drive
Mode” in this section).
Driving in Fog
If the fog is dense, avoid traveling if
possible.
When driving in mist, blanket fog or
when there is the possibility of banks
of fog, please consider some advices
listed below.
• Keep a moderate speed.
• Even in daytime, turn on the low
beams and rear fog lights. Do not
use the high beams.
• Remember that fog creates
dampness on the asphalt and thus
any type of maneuver is more
difficult and braking distances are
extended.
• Keep a safe distance from the
vehicle in front of you.
• Avoid sudden changes in speed as
much as possible.
• Whenever possible, avoid
overtaking.
• If you are forced to stop the vehicle
(breakdowns, impossibility of
proceeding due to poor visibility,
etc.), first of all, try to stop off of the
travel lane. Then turn on the hazardwarning flashers and, if possible, the
low beams.
• Sound the horn rhythmically if you
hear another vehicle approaching.
• When you get out of the vehicle, put
on the high-visibility vest (if
equipped).
CAUTION!
Be aware that rear fog lights can
bother the drivers following your
vehicle: when visibility is back to
normal, turn off these lights.
Driving in the Mountains
Mountain roads usually have many
narrow turns and curves, tunnels and
steep uphill or downhill slopes: please
consider some advices listed below.
• Drive at a moderate speed, avoid
“cutting” corners.
• When driving inside a tunnel in
daylight turn on the low beams in
advance; avoid high beams and be
aware of the rapid brightness
change. Avoid abrupt maneuvers
that could be dangerous for the
following vehicle.
• Never coast downhill with the
engine off or in neutral, and never

• Do not exceed 5 mph (8 km/h) when
driving through standing water. This
will minimize wave effects.
• Driving through standing water may
cause damage to your vehicle
drivetrain components. After driving
through standing water, do not drive
if you are not sure about drivetrain
condition. Such damage is not
covered by the New Vehicle
Warranty.
• Getting water inside your vehicle
engine can cause it to lock up and
stall out, and cause serious internal
damage to the engine. Such damage
is not covered by the New Vehicle
Warranty.
• After driving through standing
water always have the fluids (engine
oil, transmission oil, etc) checked for
contamination at anAuthorized
Maserati Dealer.
WARNING!
•Driving through standing water
limits your vehicle traction
capabilities. Do not exceed 5 mph
(8 km/h) when driving through
standing water.
•Driving through standing waterlimits your vehicle braking
capabilities, which increases
stopping distances. Therefore, after
driving through standing water,
drive slowly and lightly press on the
brake pedal several times to
progressively dry the brakes discs
and pads.
•Getting water inside your vehicle
engine can cause it to lock up and
stall out.
•Failure to follow these warnings
may result in injuries that are
serious or fatal to you, your
passengers, and others around you.
Pollution Control Devices
Even if the vehicle is fitted with
antipollution devices, the environment
deserves the greatest respect from
every one of us.
By following a few simple rules, the
driver can avoid damaging the
environment and very often can
reduce fuel consumption as well.
In this regard, some useful
information is listed here below;
please read it carefully.
• The first precaution is to follow the
Scheduled Service Plan scrupulously
(see “Scheduled Service Plan” in
section “Maintenance and Care”.
• The correct operation of the
antipollution devices not only helps
respect for the environment, but
also has an impact on vehicle
efficiency. Keeping these devices in
good working conditions is the first
rule for driving both ecologically
sound and economically.
• Always use unleaded fuel.
• If starting is difficult, do not make
prolonged attempts. In particular,
avoid push starts, towing or
downhill starts: these are all
maneuvers that can damage the
catalytic converters. For any
Driving
5
197

emergency starting, only use an
auxiliary battery.
• While driving, if the engine does not
run smoothly, you may continue
driving but reducing engine
performance to a minimum; you
should then contact theAuthorized
Maserati Dealeras soon as possible.
• Never run the engine, even if only
for testing, with one or more spark
plugs disconnected.
• Do not warm up the engine letting it
idle before starting off, except in the
event that the external temperature
is very low and, even then, for no
longer than 30 seconds.
Catalytic Converter Warnings
During normal operation the catalytic
converter produces high temperatures.
Failure to comply with following rules
can create fire hazards.
• Do not park the vehicle on
flammable materials (e.g. grass, dry
leaves, pine needles, etc.).
• Do not install heat guards and do
not remove those already fitted to
the catalytic converter and to the
exhaust manifold.
• Do not spray anything on the
catalytic converter, Oxygen sensor
and exhaust manifold.In addition to the catalytic converter
system, the vehicles are equipped with
a system for controlling fuel vapor
emissions. This system, called ORVR,
has been designed to help reduce
atmospheric pollution by the
evaporation from the fuel system
during the refueling process. Also,
specific to these vehicles is the fuel
filler neck which comes equipped with
a sealed plug that is grounded to
avoid possible sparking during
re-fueling.
WARNING!

Other Tips
• Do not warm up the engine when
the vehicle is stationary: in these
conditions the engine heats up much
more slowly, thus increasing fuel
consumption and emissions. It is
advisable to move off slowly,
avoiding high engine rpm.
• As soon as traffic conditions and the
route permit it, use a higher gear.
• Avoid depressing the accelerator
repeatedly during stops at traffic
lights or before turning off the
engine.
• Keep your speed as regular as
possible, avoiding unnecessary
braking and acceleration, which
cause fuel wastage and strongly
increase exhaust emissions.
• Turn the engine off if the vehicle
remains stationary for a long time.
• Check the tire pressure regularly: if
the pressure is too low, fuel
consumption increases and the tires
are damaged.
• Do not transport unnecessary heavy
objects in the trunk compartment.

• Carefully clean the threaded seat
before screwing the hook.
• Screw the tow hook into its seat for
at least 11 turns.
NOTE:
Maximum work angle of towing cable
or bar: 15°.
Fuel Cut-out Inertia Switch
The vehicle is equipped with a safety
switch which activates in the event of
a collision, cutting off the fuel supply
and consequently causing the engine
to stop. It also prevents fuel spreading
if the fuel lines are damaged during
the accident.
Activation of the safety switch is
signaled by the illumination of the
warning light on the instrument
cluster display.
The switch is positioned underneath
the driver seat.
In order to operate the inertia switch,
lift the seat in the highest position.
WARNING!
After a collision, if you smell fuel or
note any leakage from the fuel supply
system, do not reactivate the switch in
order to prevent any fire risks.
The activation of the inertia switch
causes all the doors and the trunk lid
to unlock, the lighting of the internal
domelight and the hazard warning
flashers.
