dashboard MASERATI GRANTURISMO 2020 Repair Manual

Parking Brake
The vehicle is equipped with an
electric automatic parking brake, also
called EPB (Electric Parking Brake).
It can be automatically engaged when
the engine is turned off and it is
disengaged when, with the engine
running, the accelerator pedal is
depressed.
When the parking brake is applied
(with the key in the ignition switch in
STOP (OFF)position), the
indicator lights up on the rev.
counter display and the related
message is displayed on the instrument
cluster for 5 seconds (see “Instrument
Cluster” in section “Dashboard
Instruments and Controls”).
During engagement and
disengagement procedures, the
indicator flashes until theparking brake has reached its
maximum activation force and is
respectively fully released.
The parking brake is automatically
applied when the engine is turned off
and the vehicle is stationary.
It can only be disengaged when the
engine is restarted.
If the key has been removed from the
ignition switch or is turned inSTOP
(OFF)position, it cannot be
disengaged.
Manual Engagement/
Disengagement
The parking brake can also be
manually engaged or disengaged
when the engine is running and when
the vehicle is moving or the key in the
ignition switch is inMAR (ON)
position, by pressing the brake pedal
and raising the lever located next to
the transmission shift lever.
When the parking brake is applied, the
indicator lights up on the rev.
counter and the related message will
be displayed on the instrument cluster.
If the engine was turned off when the
automatic engagement device was
deactivated (see “Deactivating
Automatic Operation” in this chapter)
it is possible to shift the parking brake
simply by pulling the lever upward.
CAUTION!
The main function of the EPB is to
allow safe parking of the vehicle,
therefore it must only be applied
when the vehicle is already stationary.
If the EPB is used while the vehicle is
moving and decelerating until a speed
lower of 3 mph (5 km/h) and, in
particular, until complete stop
(typically in a sudden brake), it is
necessary to have the EPB system
checked by anAuthorized Maserati
Dealer.
WARNING!
•Always hold the brake pedal pressed
during engagement or
disengagement of the parking brake.

Use of the Engine
Breaking-In
Today's most modern production
methods are designed to provide
extremely precise construction and
assembly of components. However,
moving parts do undergo a settling
process, basically in the first hours of
vehicle operation.
Do not drive keeping at a constant
high speed rate for a prolonged time.
While cruising, brief full-throttle
acceleration within the limits of local
traffic laws contributes to a good
break-in. Wide-open throttle
acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine
at the factory is a high-quality energy
conserving type lubricant. Oil changes
should be consistent with anticipated
climate conditions under which vehicle
operations will occur. For the
recommended viscosity and quality
grades, see “Refillings” in section
“Features and Specifications”.
A new engine may consume some oil
during its first few thousand
kilometers of operation. This should
be considered as a normal part of thebreak-in and not interpreted as an
indication of malfunction.
Avoid exceeding 5000 rpm for the first
620 trip mi (1000 km).
After starting the vehicle, do not
exceed 4000 rpm until the engine has
warmed up sufficiently (coolant
temperature: 149-158°F/65-70°C).
While Driving
Never travel with the tachometer
indicator approaching the peak rpm,
not even downhill. When the
tachometer indicator is approaching
the peak rpm (red colored zone), take
precautions to avoid exceeding that
limit.
Ensure proper operation of different
devices checking their respective
control telltales.
CAUTION!
• Under normal conditions, all red
warning lights on the instrument
cluster display should be off. When
they come on, they indicate 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.
WARNING!
Do not travel downhill with the
engine off, as the servo brake will no
longer function due to the vacuum
decrease and thus after a few braking
attempts, the system becomes totally
inefficient. The power steering will
also lose its efficiency under these
conditions.
Onboard Diagnostic System
Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the

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
information go to:
www.P65Warnings.ca.gov/passenger-
vehicle
Position of the Diagnostic Connector
The diagnostic connector is positioned
underneath the dashboard, next to
the hood opening lever. It can be
accessed without removing any cover.
Cruise Control (CC)
The CC enables the driver to maintain
the desired vehicle speed without
pressing the accelerator pedal,
reducing driving fatigue on highways,
especially long trips, as the set speed is
automatically maintained. A firm press
on the accelerator pedal or the
braking pedal will temporarily
deactivate the cruise control function.
CAUTION!
The device can only be switched on at
speeds exceeding 19 mph (30 km/h)
and it switches off automatically when
the brake pedal is pressed or when a
speed of 125 mph (200 km/h) is
exceeded.
WARNING!
The Cruise Control function must only
be activated when traffic and the
route permit a constant speed to be
maintained safely for a sufficiently
long distance.
Controls
The controls of the CC are located on
the multifunction lever, on the left
side of the steering wheel.
• The innermost ON/OFF switch has
two positions:
OFF: the CC is deactivated;
ON: the CC is active. When the CC is
activated, the
green warning
light on the display illuminates
together with the message “Cruise
control on”.
• The rotating section in the middle of
the left multifunction lever is used to
store the vehicle speed, to keep it
constant or to increase or decrease
the speed stored. Turn the rotating
section to position "+" to save the
speed reached or to increase the
speed stored. Turn the rotating
section to position "–" to decrease

that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after
replacing one or more tires or wheels
on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
General Information
The Tire Pressure Monitoring System
(TPMS) will warn the driver of a low
tire pressure according to the vehicle
recommended cold pressure indicated
on the table “Tire Inflation Pressure”
in section “Features and
Specifications” and on the label
applied on the driver's side at the base
of the rear door pillar.
The cold tire inflation pressure must
not exceed the maximum inflation
pressure molded into the tire sidewall.
Check “Tires – General Information” in
section “Driving” for information on
how to properly inflate the tires.
The tire pressure will also increase as
the vehicle is driven - this is normal
and there is no adjustment required
when this occurs.
The TPMS will warn the driver of a low
tire pressure if the tire pressure falls
below the low-pressure warning limit
for any reason, including lowtemperature effects and natural
pressure loss of the tire.
The TPMS will continue to warn the
driver of low tire pressure as long as
the condition persists and will not turn
off until the tire pressure is equal or
above the recommended cold
inflation pressure.
The TPMS monitors the tire pressure
by means of special sensors fitted
inside the wheel rims, in position with
the inflation valve.
These sensors transmit a signal that is
detected by the antenna integrated in
the ECU.
The ECU processes this information
and, via the CAN line, transmits a
series of tire pressure data and system
errors, if any, to the instrument cluster.
The display may show the information
received by means of specific screen
pages, which can be recalled by
pressing briefly the "MODE" button
(see "TFT Display: Controls" in chapter
"Instrument Cluster" of the section
Dashboard Instruments and
Controls").
WARNING!
The TPMS warns the driver that the
tire pressure has decreased. This
warning does not exempt the driver
from periodically checking the tires
and from complying with the
prescribed tire pressure levels.
CAUTION!
• The TPMS has been optimized for
the original equipment tires and
wheels. TPMS pressures and warning
have been established for the tire
size equipped on your vehicle.
Undesirable system operation or
sensor damage may occur when
using replacement equipment that is
not of the same size, type, and/or

style. Aftermarket wheels can cause
sensor damage. Do not use
aftermarket tire sealants or balance
beads, as damage to the sensors may
result.
• The system can temporarily
experience radio-electric interference
emitted by devices using similar
frequencies.
• After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve
stem and damage the TPMS internal
sensor.
NOTE:
•Driving on a significantly
underinflated tire causes the tire to
overheat and may lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain
correct tire pressure using an
accurate tire pressure gage, even if
under-inflation has not reached thelevel to trigger illumination of the
TPMS light
.
•Seasonal temperature changes will
affect tire pressure, and the TPMS
will monitor the actual tire pressure
in the tire.
Viewing Messages on the
Display
By pressing repeatedly the “MODE”
button of the control panel on left
side of the steering column, the user
can access the information page that
shows the pressure values of each tire
(“Tire Pressure” screen page: see
paragraph "TFT Display: Screen Pages"
in chapter "Instrument Cluster" of
section "Dashboard Instruments and
Controls").
If system faults or low pressure is
detected on a not indentified tire,"Check Tire Pressure" or "TPMS
Malfunction" pop-up message will be
displayed for 10 seconds. The
amber warning light will
permanently illuminate on the right
side of the instrument cluster display.
With a malfunction detected, the "Tire
Pressure" screen page will not be
available while will be available the
calibration screen page.
The “Tire Pressure” screen page
becomes available again, until the
malfunction is corrected.
Low Tire Pressure Conditions
The signal transmitted by the ECU
activates messages and symbols on the
TFT display with two priority levels
corresponding to the following
thresholds:
• Soft Warning: if the pressure is 10%
lower than the rated pressure;
• Hard Warning: if the pressure is 17%
lower than the rated pressure.
The system refers to the rated pressure
acquired after calibration.
The two alarm thresholds for
monitoring the tire pressure
respectively activate the following
alerts:
• “Check tire pressure” illuminates on
the display when the pressure of one

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 “ReformulatedGasoline”. 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
withoutMMT 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.

Refueling
Fuel Filler Neck Access
The fuel filler door is found on the
rear, left-hand side of the vehicle.
To open the fuel filler door, press
button on the left control panel next
to the steering wheel.
It can be operated only when the key
is removed from the ignition switch or
turned toSTOP (OFF)position.
Refill the Tank
The fuel filler neck is provided with
external cap.
• Rotate counterclockwise and remove
the fuel filler cap. The cap hermetic
seal may result in a slight pressure
increase inside the tank. Any hissing
noise while the cap is being opened
is therefore completely normal. Thecap is linked to the filler neck with a
strap, to prevent it from being lost
while refueling.
• When refueling, the cap must remain
attached to the door by means of the
hook provided.
• Insert the fuel nozzle fully into the
filler.
WARNING!
•To avoid the risk of fire, do not
approach the filler with open flames
or cigarettes!
•To avoid the risk of inhaling noxious
fumes, do not breathe close to the
fuel filler door, when opened.
•Never have any smoking materials lit
in or near the vehicle when the fuel
filler door is open or the tank is
being filled.
•Never add fuel when the engine is
running. This violates most
fire-prevention regulations and may
cause the
Malfunction Indicator
Light (MIL) to turn on (see
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
• Fill the vehicle with fuel. Fuel tank
capacity is indicated in the
“Refillings” table in section
“Features and Specifications”.
When the fuel nozzle “clicks” or
shuts off, the fuel tank is basically
full: it is possible to further ensure
refueling by enabling the fuel nozzle
additional fuel supply until two
clicks. After the two additional clicks,

Engine Overheating
To reduce potentially overheating of
the engine in city traffic, while
stationary, place the transmission in N
(Neutral), but do not increase the
engine idle speed.
NOTE:
There are steps that you can take to
slow down an impending overheat
condition:
•If your air conditioner (A/C) is on,
turn it off. The A/C system adds heat
to the engine cooling system and
turning the A/C off can help remove
this heat.
•You can also turn the temperature
control to maximum heat, the mode
control to floor and the blower
control to high. This allows the
heater core to act as a supplement to
the radiator and aids in removing
heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system
could damage the engine. If the
temperature gauge is positioned on
the red zone (refer to “Instrument
Cluster” in section “DashboardInstruments and Controls”), pull over
and stop the vehicle. Idle the vehicle
with the air conditioner turned off
until the temperature gauge drops
back into the normal range. If the
temperature gauge remains on the red
zone turn the engine off immediately
and contact theAuthorized Maserati
Dealer.
WARNING!
You or others can be badly burned by
hot engine coolant (antifreeze) or
steam from your radiator. If you see or
hear steam coming from under the
hood, do not open it until the radiator
has had time to cool.
Never try to open a coolant bottle
pressure cap (refer to “Maintenance
Procedures” in section “Maintenance
and Care”) when the radiator is
overheated.
In case of a Punctured Tire
The vehicle can be equipped with a
tire repair kit or with a compact spare
wheel.
Using Tire Repair Kit
Small punctures up to 1⁄4” (6 mm) in
the tire tread can be sealed using the
tire repair kit, fitted beneath the floor
panel of the trunk compartment.
The kit comes in a bag and consists of
two parts:
• an electric compressor with pressure
gage, hose to be connected to the
punctured tire and power cable;
• a gas cylinder containing sealant.
