2020 MASERATI GRANTURISMO sensor

Sport Skyhook Suspension
(for versions/markets,
where provided)
The electronic system controlling the
vehicle suspension uses the
sophisticated on board sensors and is
aimed at optimizing vehicle
performance.
The system is capable of constantly
monitoring suspension damping by
means of the actuator fitted on each
shock absorber (Skyhook type). This
way, the shock absorber setting is
suited to the road surface conditions
and vehicle dynamics, thus improving
passenger comfort and road-holding.
By pressing button “SPORT” on the
central console, the driver can choose,
even while driving, a normal or
dynamic-type setting for the
suspension, depending on their own
driving style.This way, the system operates with a
shock absorber “softer” setting in
NORMAL drive mode, and a “harder”
setting if SPORT drive mode is selected
(see “Drive Mode” in section
“Driving”).
The strategy used by the system
controlling suspension damping is
aimed at reducing the vertical
oscillations of the vehicle (rolling and
pitching) to a minimum.
The activation of SPORT drive mode
sets the suspension for sports-style
driving and acts on the ASR and
gearbox systems as well, modifying
their setting for dynamic-style driving.
System Components
The system is controlled by an ECU
which manages the solenoid valves on
each shock absorber in response to the
sensor signals, thus adjusting
suspension damping and setting.The sensors which enable the ECU to
calculate the vehicle speed, vertical
and side acceleration, as well as the
instantaneous braking system
pressure, thereby controlling
suspension damping, are the
following:
• front left-hand vertical acceleration
sensor;
• front right-hand vertical acceleration
sensor;
• rear vertical acceleration sensor;
• front left-hand wheel acceleration
sensor;
• front right-hand wheel acceleration
sensor;
• lateral acceleration sensor;
• driving speed sensor;
• brake pedal switch.
Self-diagnostics
Whenever the engine is started, the
system performs a self-diagnostic
cycle. If a malfunction is found, the
amber warning light is displayed
accompanied by the message “Check
suspensions” (see paragraph
"Malfunction Indicators" in this
chapter).

Air Conditioning Controls
The vehicle is equipped with an
automatic dual-zone air conditioning
system that allows to adjust separately
the air temperature and the airflow
distribution in the left and in the right
zone of the passenger compartment,
according to the requests of the driver
and the front passenger.
A humidity sensor, positioned on the
inner surface of the windshield, over
the rearview mirror, allows the A/C
system to prevent/ eliminate fogging
of the windshield and side windows.
The best efficacy in preventing
fogging is obtained by selecting the
AUTO function, described later.
A dual zone solar sensor, positioned on
the center of the dashboard upper
surface, helps to achieve the best
comfort in presence of solar radiation.
CAUTION!
To ensure proper functioning of the solar
sensor, do not apply adhesive parking
stickers, etc. in the checking area
between the sensor and the windshield.
Therefore, keep the windshield and the
sensor clean to prevent accumulation of
dust or other impurities.

engage the parking brake, but also to
shift the transmission shift lever to P
(Park) before leaving the vehicle.
When parking on hill roads, it is
important to turn the front wheels
toward the curb on a downhill grade
and away from the curb on an uphill
grade.
Apply the parking brake before
placing the shift lever in P (Park),
otherwise the load on the
transmission locking mechanism may
make it difficult to move the shift
lever out of P (Park).
In certain conditions, it is however
advisable to disengage the parking
brake manually and slightly apply the
service brake for starting off. This is
advisable when there are obstacles
very close to the vehicle in the
direction in which you intend to move.
Brake and Stability
Control System
The vehicle is equipped with an
Electronic Stability Control (ESC)
anti-yawing system, which helps to
maintain directional control in the event
of loss of grip of the tires. The system is
able to detect potentially dangerous
situations for the stability of the vehicle
and automatically sets the brakes on all
four wheels in a differentiated manner,
in order to provide a torque settlement
of the vehicle.
ESC includes the following subsystems:
• ASR (Anti-Slip Regulation)
• ABS (Anti-lock Braking System)
• EBD (Electronic Brake-force
Distribution)
• HBA (Hydraulic Brake Assistance)
• BOS (Brake Override System)
WARNING!
•These systems cannot prevent the
natural laws of physics from
affecting the vehicle, nor can they
increase traction, braking or steering
efficiency beyond that afforded by
the condition of the vehicle brakes
and tires.•These systems cannot prevent
collisions, including those resulting
from excessive speed in turns,
following another vehicle too
closely, or hydroplaning.
•The capabilities of a vehicle
equipped with these systems must
never be exploited in a reckless or
dangerous manner that could
jeopardize the driver’s and the
passenger’s safety or the safety of
others.
Electronic Stability Control
(ESC)
This system enhances directional
control and stability of the vehicle
under various driving conditions. The
ESC corrects over steering and under
steering of the vehicle by applying the
brake to the appropriate wheel.
Engine power may also be reduced to
assist in counteracting the conditions
of instability and maintain the right
direction. The system is also able to
reduce the engine power.
Through sensors fitted on the vehicle,
the ESC system detects the driver’s
chosen direction comparing it to the
one maintained while running. In case
of discrepancy between the required
trajectory and the current one, the

• in the event of loss of grip on wet
roads (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
nearestAuthorized 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.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehiclecan 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

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.

•Under-inflation increases tire flexing
and can result in tire overheating.
•Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and potholes can cause
damage that results in tire failure.
•Over-inflated or under-inflated tires
can affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
•Unequal tire pressures can cause
steering problems.
•Unequal tire pressures from one side
of the vehicle to the other can cause
the vehicle to drift to the right or
left.
•Always drive with each tire inflated
to the recommended cold tire
inflation pressure.
Economy
Improper inflation pressures may
cause uneven wear patterns to
develop across the tire tread. These
abnormal wear patterns will reduce
tread life resulting in a need for
earlier tire replacement. Under-
inflation also increases tire rolling
resistance resulting in higher fuel
consumption.Ride comfort and vehicle stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Pressure Checkup
The proper cold tire inflation pressure
is indicated on the driver's side rear
door pillar and on the table “Tire
Inflation Pressure” in section
“Features and Specifications”.
Inflation pressure specified on the
table always refers to “cold tire
inflation pressure”. Cold tire inflation
pressure is defined as the tire pressure
after the vehicle has not been driven
for at least three hours, or driven less
than 1 mi (1,6 km) after a three hour
period.
Check tire pressures more often in
case of significant outside
temperature changes, as tire pressure
varies according to temperature
changes.
The pressure should be checked and if
necessary adjusted; tire wear and
overall conditions should also be
checked monthly. Tire pressures
change by approximately 1 PSI (0,07
bar) per 12°F (7°C) of air temperature
change. Keep this in mind whenchecking tire pressure inside a garage,
especially in winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 PSI
(0,21 bar) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6
PSI (0,13 to 0,4 bar) during operation.
DO NOT reduce this normal pressure
build-up or your tire pressure will be
too low. After inspecting or adjusting
the tire pressure, always reinstall the
valve stem cap. This will prevent
moisture and dirt from entering the
valve stem, which could damage the
valve stem and the TPMS sensor
connected to it.
Tread Wear Indicators
Tread wear indicators are in the
original equipment tires to help you
determine when your tires should be
replaced.
These indicators are molded into the
bottom of the tread grooves.
When the tread is worn to one of the
tread wear indicators, the tire should
be replaced.
