2020 MASERATI GRANTURISMO CONVERTIBLE service

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.

•Never exceed the maximum speed
rating of the tires. Risk of accident
and serious personal injury due to
excessive speed.
•Failure to equip your vehicle with
tires having adequate speed
capability can result in tire failure.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
Winter Tires
These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle. Winter or all-season tires can
be identified by the M+S (Mud &
Snow) or 3PMSF (3 Peaks Mountain
Snow Flake) designation on the tire
sidewall.
Before mounting winter tires, contact
anAuthorized Maserati Dealerto
receive the technical information
necessary to advise you on wheel and
tire compatibility.
As to the type of tires to use, inflation
pressures and winter tires
specifications, carefully follow the
indications as reported in the“Technical Data” and “Tire Inflation
Pressure” chapters in section “Features
and Specifications”.
WARNING!
The standard tires profile and rubber
mixture are optimized for wet and dry
driving conditions. Standard tires may
not prove favorable for snow
conditions.
NOTE:
Snow tires should have the same load
capacity as original equipment tires
and should be mounted on all four
wheels.
Snow Chains
Maserati approved traction devices (or
snow chains) may be used to improve
traction on compacted snow in heavy
snow conditions.
The use of snow chains is specified by
local regulations of each country.
Use snow chains of reduced
dimensions, with a maximum
projection of 0.35 in (9 mm) beyond
the tire tread.
Maserati recommended to use snow
chains KONIG, type “Supermagic”.The snow chains may be fitted only on
rear wheel tires.
Please, contact your Service for further
information.
Check the snow chain tension after
driving for a distance of about 55 yd
(50 m) with the chains fitted.
With the snow chains fitted, it is
advisable to deactivate the ESC system
(see chapter “Drive Mode” in this
section).
CAUTION!
• The use of non-recommended snow
chains may damage the vehicle.
• Broken chains can cause serious
damage. Stop the vehicle
immediately if noise occurs that
could indicate chain breakage.
Remove the damaged parts of the
chain before further use.
• Do not exceed 30 mph (50 km/h).
• Drive cautiously and avoid severe
turns and large bumps, especially
with a loaded vehicle.
• Avoid holes in the road, do not drive
over steps or sidewalks and do not
drive on long stretches without
snow. This will prevent damage to
the vehicle and the roadbed.

“--,--” 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.
Driving

Materials Added to Fuel
All gasoline sold in the United States is
required to contain effective
detergent additives. Use of additional
detergents or other additives is not
needed under normal conditions and
they would result in additional cost.
Therefore, you should not have to add
anything to the fuel.
Fuel System Warnings
WARNING!
Follow these guidelines to maintain
your vehicle's performance:
•
The use of leaded gasoline is
prohibited by Federal and Provincial
law. Using leaded gasoline can impair
engine performance and damage the
emissions control system.
•The use of fuel additives, which are
now being sold as octane enhancers,
is not recommended. Most of these
products contain high
concentrations of methanol. Fuel
system damage or vehicle
performance problems resulting
from the use of such fuels or
additives is not the responsibility of
Maserati.
NOTE:
Intentional tampering with the
emissions control system can result in
civil penalties civil penalties and could
void the vehicle warranty.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust
gases is deadly. Follow the
precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They
contain carbon monoxide, a
colorless and odorless gas, which
can kill. Never run the engine in a
closed area, such as a garage, and
never sit in a parked vehicle with
the engine running for an extended
period. If the vehicle is stopped in
an open area with the engine
running for more than a short
period, adjust the ventilation system
to force fresh, outside air into the
vehicle.
•Guard against carbon monoxide
with proper maintenance. Have the
exhaust system inspected every time
the vehicle is raised. Have anyabnormal conditions repaired
promptly. Until repaired, drive with
all side windows fully open.
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

before driving through the standing
water.
• 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 water
limits 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
207

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.

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.

In the Event of an
Accident
It is important always to keep calm.
• If not directly involved, stop at a safe
distance of at least 10 yards away
from the accident area.
• If on a highway, stop without
obstructing the emergency lane and
be especially careful if you need to
exit the vehicle.
• Turn off the engine and switch on
the hazard warning flashers.
• At night, illuminate the accident
area with the headlights.
• Always act with caution to avoid the
risk of being crashed into by other
drivers.
• Indicate that an accident has
occurred by placing the emergency
triangle (if equipped) in a well
visible position and at the prescribed
distance.
• Call the emergency services,
providing as much information as
possible. On the highway, use the
special call boxes.
• Remove the ignition key (if present)
from the vehicles involved.
• If fuel or other chemical products
can be smelled, do not smoke andask people around you to put their
cigarettes out.
• To extinguish fires, even small ones,
use a fire extinguisher, blankets,
sand or earth. Never use water.
• In multiple accidents occurred on
highways, particularly where
visibility is poor, there is a high risk
of being involved in other collisions.
Leave the vehicle immediately and
move away from the area.
In case of Injured Persons
• Never leave the injured person
alone. Persons not directly involved
in the accident are also required to
give assistance.
• Do not crowd around injured
persons.
• Reassure the injured person that
help is on the way.
