2019 MASERATI GRANTURISMO CONVERTIBLE fuel pump

Normal Starting of the
Engine
WARNING!
It is dangerous to run the engine in an
enclosed area. The engine consumes
oxygen and discharges carbon
dioxide, carbon monoxide and other
toxic gases in the atmosphere.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are know to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more

When you open a door to get into the
car
, the instrument cluster turns on.
The TFT displays the complete
odometer, time, outside temperature
and the
open doors indicator.
Before starting the engine, close the
doors, adjust your seat, the inside and
outside mirrors, fasten your seat belt
and instruct all other occupants to
buckle their seat belts.
Make sure that the Electric Parking
Brake (EPB) is applied.
The shift lever must be in P (Park) or N
(Neutral) position before you can start
the engine. Apply the brakes before
shifting into any driving gear (see
“Automatic Transmission” in this
section).
CAUTION!
• Before starting the engine, switch off the electrical devices with a high
power consumption (air-conditioning
and heating system, heated rear
window, headlights, etc.).
• Do not start the engine if the fuel level in the tank is low. Press the brake pedal and turn the key
in

the ignition switch to MAR (ON)
position.
Instrument cluster displays the initial
sequence with warning light and
analog instruments test routine.
Turn the key into AVVposition and
release it when the engine starts. The
key will return to MAR (ON)position
automatically.
Do not hold the key in AVVposition
for a long time.
If the engine fails to start, the starter
will disengage automatically after 10
seconds. If you wish to stop the
cranking of the engine prior to
starting it, turn the key to STOP (OFF)
position.
If the engine does not start, turn the
key to STOP (OFF) position and wait
for the gear display to go off. Then
repeat the entire procedure.
NOTE:
Normal starting of either a cold or a
warm engine is obtained without
pumping or pressing the accelerator
pedal.

• in the event of loss of grip on wetroads (aquaplaning).
The ASR system works in combination
with the electronic suspension control
system: in normal conditions (SPORT
mode off), stability in low and
medium grip conditions has priority,
while with SPORT mode active, the
system favors traction, thereby
optimizing vehicle performance on dry
asphalt.
The ASR system is automatically
activated every time the engine is
started and can be deactivated by
pressing
(ESC Off) button (see
"Drive Mode" in this section).
ASR System Failure
In the event of a fault, the system is
automatically disabled and cannot be
re-activated. While driving, this
condition is signaled by the
amber
warning light on the instrument
cluster display, which illuminates
together with the message “ASR
unavailable go to dealer”. Also the
(ESC On) amber warning light
illuminates inside the tachometer with
the message indicating that the ESC
system is unavailable. In this case drive
with the greatest care and have the
system immediately checked by the
nearest Authorized Maserati Dealer .MSR Function
The ASR system also controls the
engine braking torque when the
accelerator pedal is released under
low grip conditions (e.g., snow, ice,
etc.): in these conditions, the high
braking torque provided by the
engine may cause instability of the
vehicle.
The system, using the same sensors as
the ABS, detects skidding of one or
both driving wheels when the
accelerator is released and opens the
motor-driven throttle of the engine
fuel system thereby reducing the
braking torque and re-establishing the
maximum grip conditions for the
driving wheels.
WARNING!
The maximum deceleration that can
be obtained with the engine brake
always depends on the tire grip on
the road surface. Snow or ice
obviously reduce grip values.

Anti-Lock Braking System (ABS)
and Electronic Brake-force
Distribution (EBD)
The Anti-Lock Brake System (ABS)
provides increased vehicle stability and
brake performance under most
braking conditions. The system
automatically “pumps” the brakes
during severe braking to prevent
wheel lock-up.
The Electronic Brake-force Distribution
(EBD) prevents the rear wheels from
over-braking and provides greater
control of available braking forces
applied to the rear axle.

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 (MIL)
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
(MIL) 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.

Resetting the Inertia Switch
• Turn the key in the ignition switch to STOP (OFF) position.
• Check that there is no leakage from the fuel system.
• If no leaks are found, reset the inertia switch which stops the fuel
pump operation by pressing button
on the switch. • Turn the key in the ignition switch to
MAR (ON) position: wait a few
seconds and turn it to ACCposition.
• Check that the
warning light on
the instrument cluster display is off.
• Check once again that there are no fuel leaks.
NOTE:
After resetting the inertia switch,
please contact an Authorized Maserati
Dealer.
