Warnings while Driving with CC
WARNING!
• When driving with CC activated, do
not shift to N (Neutral) position. It is
advisable to activate CC only when
traffic and road conditions permit
safe use of this device, that is: on
straight and dry roads, expressways
or highways, smooth flowing traffic
and smooth asphalt. Do not activate
this device when driving in town or
in heavy traffic.
• CC can only be activated at speeds
exceeding 19 mph (30 km/h).
• CC can only be activated in 4th, 5th
or 6th gear, depending upon the
vehicle speed.
• When driving downhill with the CC
activated, the vehicle may pick up
speed slightly exceeding the speed
stored, due to the change in the
engine load.
• In the event of malfunctioning or
failure of CC, turn ON/OFF switch to
"OFF" position and contact the
Authorized Maserati Dealer after having checked that the relative
fuse is in proper working order.
• ON/OFF switch can be always left at
"ON" position without damaging
the CC. In any case, it is advisable to
deactivate the CC when it is not in
use. Turn ON/OFF switch to "OFF"
position to prevent any speeds from
being unintentionally stored.

285/40 ZR19 (Y100) XL
Size Designation:
P= Passenger car tire size based on
U.S. design standards
“...blank...” = Passenger car tire
based on European design standards
285 = Section width in millimeters
(mm)
40 = Aspect ratio in percent (%) —
Ratio of section height to section
width of tire
ZR = Construction Code
• Z: means a tire usable at speeds greater than 150 mph (240 km/h)
• R: means radial construction
19 = Rim diameter in inches (in)
Service Description:
100 = Load Index — A numerical
code associated with the maximum
load a tire can carry
Y = Speed Symbol — A symbol
indicating the range of speeds at
which a tire can carry a load
corresponding to its load index
under certain operating conditions.
The maximum speed corresponding
to the speed symbol should only be
achieved under specified operating
conditions (i.e., tire pressure, vehicle
loading, road conditions, and posted
speed limits)
Load Identification:
“...blank...” = Absence of any text on
the sidewall of the tire indicates a
Standard Load (SL) tire
XL = Extra Load (or reinforced) tire
LL = Light Load tire
Tire Identification Number (TIN)
The TIN may be found on one or both
sides of the tire, however the date
code may only be on one side. Tires
with white sidewalls will have the full
TIN, including the date code, located
on the white sidewall side of the tire. Look for the TIN on the outboard side
of black sidewall tires as mounted on
the vehicle. If the TIN is not found on
the outboard side, then you will find it
on the inboard side of the tire.
EXAMPLE: DOT MA L9 ABCD 0313
DOT
= Department of Transportation
— This symbol certifies that the tire is
in compliance with the U.S.
Department of Transportation tire
safety standards and is approved for
highway use.
MA = Code representing the tire
manufacturing location (two digits).
L9 = Code representing the tire size
(two digits).
ABCD = Code used by the tire
manufacturer (one to four digits).
03 = Number representing the week
in which the tire was manufactured
(two digits). In this case, 03 means

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 the level 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
5
196

or more tires falls below the
low-pressure alarm threshold (Soft
Warning). The tire with its low
pressure value will be highlighted in
amber color for 30 seconds.
• The tire with its low pressure value in amber color, the message “Low
inflation pressure tire” and "Do not
drive on" in rolling mode with the
amber warning light always on
activates when the pressure of one
or more tires is below the minimum
pressure alarm threshold (Hard
Warning). The TPMS screen page is displayed for
30 seconds and then the screen page
that was previously displayed
reappears. If the malfunction persists,
the TPMS screen page shown in the
picture will be automatically displayed
for 30 seconds the next time the
engine is started.
The driver can call up the TPMS screen
page at any time to display which tires
have low pressure.
Occasionally, the system may not
detect which wheel signals a
malfunction. If this is the case, then
only the message “Check tire
pressure” will be displayed on the TFT
display.
Punctured Tire
When the instrument cluster receives a
signal from the tire pressure ECU
indicating that the pressure level of
one or more tires is below the alarm threshold or there is a sudden pressure
loss (punctured tire). The
amber
warning light will permanently
illuminate on the instrument cluster
and screen pages shown in the picture
will alternate on the display for 30
seconds: then the screen page that
was previously displayed reappears on
the TFT display.
If the malfunction persists, the display
will show these screen pages for 30
seconds every time the key in the
ignition switch is subsequently turned
back to MAR (ON) position.
These screen pages will be displayed
until the situation is corrected and the
system is calibrated again as required
by the system.
System Not Calibrated
The system must be calibrated:
• after replacing one or more tires;
Driving
5
197

• after inverting the wheels;
• if you are not sure whether at leastone of the operations above was
performed.
If you simply corrected the tire
inflation pressure, you do not need to
recalibrate the system.
In the event that the system has not
been calibrated or calibration has been
performed incorrectly and following
replacement or reversal of one or
more tires, the
amber warning light
will flash for 85 seconds on instrument
cluster, and the TFT display will show
screen page with dashes “--,--” in the
place of the pressure levels of each
tire.
When the TPMS display cycle ends (30
seconds), the car symbol with message
will disappear and reappears the
screen page that was previously
displayed will reappear: the
amber warning light remains on until the
system has been calibrated.
To calibrate the system, select the
screen page “TPMS calibration” by
pressing the “MODE” button. A
message will tell you to press and hold
button “+” to activate the calibration
procedure.
NOTE:
The TPMS calibration operation is
possible even with the engine running
but the vehicle must be stationary
(0 mph-km/h).
The system may take up to 10 minutes,
by driving at speed lying between
6 mph (10 km/h) and 80 mph
(130 km/h), to complete the process.
During this time the
amber symbol
and the message “Calibration
activated” will be displayed for 10
seconds.
During calibration, if the user recalls
the information page showing the
pressure levels of each tire, dashes
Driving
5
198

“--,--” 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
an Authorized 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

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.

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. The cap 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,
