2020 MASERATI GRANTURISMO CONVERTIBLE sensor

WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability
The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning could
result in tire failure.
Replacement Tires
NOTE:
In order to maintain high performance
and safety level under all driving
conditions, Maserati strongly
recommends to use tires equivalent to
the originals in size, quality and
performance when replacement is
needed.
For the size designation of your tire
see the label on the driver's side rear
door pillar or see table “Wheels” in
section “Features and Specifications”.
The “Load Index” and “Speed Symbol”
for your tire will be found on the
original equipment tire sidewall.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling.
If you ever replace a wheel assembly,
make sure that the wheel’s
specifications (valve, TPMS sensor and
tire) match those of the original
wheels. Failure to use equivalent
replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
YourAuthorized Maserati Dealeris
available to provide suggestions as tothe types of tires most suited to the
use foreseen by the Customer.
WARNING!
•Do not use a tire, wheel size or
rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and
performance characteristics,
resulting in altered steering,
handling, and braking operations of
the vehicle. This can cause
unpredictable handling and stress to
steering and suspension
components. Use only the tire and
wheel sizes with load ratings
appointed for your vehicle.
•Never use a tire with a smaller load
index or capacity, other than what
was originally equipped on your
vehicle. Using a tire with a smaller
load index could result in tire
overloading and failure.
•Always check the maximum speed
rating on the tire sidewall on any
tire on the vehicle.

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
Driving

“--,--” will be displayed in the place of
the values.
NOTE:
•The system will not perform
calibration if the pressure is below 2
bar (29 psi).
•To allow the system to acquire the
sensors’s data, after the startup of
the car, if possible avoid to stop.
During this interval the TFT display
can show screen page with dashes
“--,--” in the place of the pressure
levels of each tire.
•If calibration is not completed within
10 minutes of driving the car, the
instrument cluster shows “TPMS
Malfunction” pop-up message and
“Tire Pressure” screen disappear. The
warning light remains light on.
TPMS Malfunction
Screen page shown in picture may
appear in the following cases:
• malfunction in the ECU
system/wiring;
• no signal reception by one or more
sensors due to malfunctioning,
broken or dead battery;
• ECU malfunction.The display procedure follows the
usual logic of malfunctions. Therefore,
after 30 seconds, the display will show
the screen page that was active before
the malfunction occurred.
In addition to screen page being
displayed, the
amber warning
light, which is permanently
illuminated on the instrument cluster,
will flash for 85 seconds, after which it
will remain permanently on until the
situation is corrected. The information
page that shows the pressure value for
each tire cannot be recalled.
Fuel Requirements
The engines are designed to meet all
environmental regulations and
provide excellent fuel economy and
performance when using unleaded
premium gasoline with an AKI octane
rating of 91 or above. AKI (Anti Knock
Index) is an average on the Research
Octane Number, RON, and the Motor
Octane Number, MON (RON + MON/2
gives you the AKI).
For vehicle top performance, use
unleaded premium gasoline with no
less than 93 minimum AKI octane
rating.
Poor quality gasoline can cause
problems such as hard starting,
stalling, and hesitations. If you
experience these symptoms, try
another brand of gasoline before
considering service for the vehicle at
anAuthorized Maserati Dealer.
Besides using unleaded gasoline with
the proper octane rating, gasoline
that contain detergents, anti-corrosion
and stability additives are
recommended. Using gasoline that
have these additives may help improve
fuel economy, reduce emissions, and
maintain vehicle performance.

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!
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
information go to:www.P65Warnings.ca.gov/passenger-
vehicle
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.

• Return the cap and dipstick to their
position and wait for a few minutes
to allow the oil to reach the oil pan.
• Check the level again.
After topping up, the
engine oil
level warning light may not go off for
some time while the system is
performing the necessary checks. This
is normal.
Engine Oil Filter Replacement
The engine oil filter should be
replaced with a new filter at every oil
change.
Contact anAuthorized Maserati
Dealerto perform this service.
Automatic Transmission Oil Check
Contact anAuthorized Maserati
Dealerfor the oil level check.
Power Steering Fluid Level Check
With the vehicle on a level ground
and the engine cold, check the fluid
level of the power steering reservoir.
• To carry out the check, unscrew the
cap, clean the dipstick with a dry and
clean cloth.
• Retighten the cap then unscrew it
again and check the level: it should
match the “MAX” notch marked on
the dipstick. In hot oil conditions,the level may even exceed the
“MAX” notch.
• If necessary, top up with fluid
making sure that it has the same
characteristics as the one already
used in the system (refer to
“Refillings” in section “Features and
Specifications”).
CAUTION!
Make sure that the power steering
fluid does not come in touch with the
engine hot parts as it is flammable.
Engine Air Filter Replacement
Contact anAuthorized Maserati
Dealerto have the air filters replaced.
Wiper Maintenance and Blades
Replacement
WARNING!
It is dangerous to operate or service
the wiper blades with the wipers in
an active position (right multifunction
lever in any position different than
“OFF”) and with the key in the
ignition switch in the MAR (ON)
position. The rain sensors may
suddenly activate the wipers.
Windshield Wiper Maintenance
Life expectancy of wiper blades varies
depending on the geographical area’s
weather conditions where the car is
used and frequency of use. Poor
performance of blades may be present
with chattering, marks, water lines or
wet spots. If any of these conditions
are present, clean the wiper blades or
replace if necessary.
Clean the rubber edges of the wiper
blades and the windshield periodically
with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove
accumulations of salt or road film.
Operation of the wipers on dry glass
for long periods may cause
deterioration of the wiper blades.
