Engine Start Failure
CAUTION!
• Do not attempt to push or tow your
vehicle to get it started. Vehicles
equipped with an automatic
transmission cannot be started this
way.
• If the vehicle battery is dead, booster
cables may be used to obtain a start
from a booster battery or the
battery in another vehicle. This type
of start can be dangerous if done
improperly. See “Auxiliary Jump
Start Procedure” in section “In an
Emergency” for further information.
Starting by cold engine
Start-off slowly, avoiding sudden
acceleration and rev the engine up at
low medium speeds. High-
performance driving should be
avoided until the engine temperature
reaches 65-70°C (149-158°F).
Engine Turn-Off
• Place the shift lever in P (Park) (see
“Automatic Transmission” in this
section).
• With the engine at idle, turn the key
in the ignition switch toSTOP (OFF)position. A burst on the accelerator
pedal before turning off the engine
has no purpose and increases fuel
consumption.
WARNING!
Never leave a vehicle out of the P
(Park) position, as it could move.
The key can only be removed from the
ignition switch when the transmission
is in P (Park) position and within 30
seconds after turning the key toSTOP
(OFF)position. If you do not remove
the key within 30 seconds, you will
need to turn it back toMAR (ON)and
then toSTOP (OFF)position to have a
further 30 seconds within which to
remove the key from the ignition
switch.
In the event that the key unlocking
system fails or if it is not possible to
shift the transmission to P (Park)
position, to remove the key you must
turn it toSTOP (OFF)position, then
remove the cap shown in picture using
a pen or sufficiently pointed tool.
Then press the button just uncovered
and at the same time extract the key
from the ignition switch. Once the key
has been removed, refit the removed
cap.

“--,--” 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.

Once the set limit in kilometers or the
expiry date is reached, every time the
instrument cluster is turned on
thereafter, the message “Service
coupon expired” will be displayed.Selecting the function “Service” in the
“Trip” menu of the MTC+, you can
display the next service deadline (see
“Onboard Computer (Trip)” in section
"Driving"). The residual mileage left
to the service deadline is always
indicated. The days remaining before
the scheduled service date instead, are
only indicated starting from the 511th
day (approximately 17 months).
NOTE:
Every time the battery is disconnected,
the date and time must be set (see
"MTC+ Settings" in section
"Dashboard Instruments and
Controls").
CAUTION!
• Failure to reset the system may cause
it to malfunction and indicate wrong
maintenance service intervals.
• If you incorrectly set a date earlier
than the last service coupon, the
system updates the indication
“Scheduled service within... days”
automatically entering a later date
considering the maximum number of
days allowable for the next service
coupon.

that all the electrical/electronic
systems in the vehicle work efficiently.
Maintaining Battery Charge
If you perform short daily trips
(approximately 10 miles/16 km), which
correspond to an annual total of 4000
miles/6000 km, or when the vehicle is
not going to be used for one week or
more, Maserati recommends
connecting the vehicle to a battery
charger, to save you the trouble of
having to recharge the battery (see
“Battery Charge Maintainer
Operation” in this chapter).
The battery charge maintainer will
keep the battery charged properly and
at the correct voltage levels required
by the systems and devices in the
vehicle.
Before using the battery charge
maintainer, carefully follow the
instructions provided.
If you do not use a battery charge
maintainer to prevent the battery
from going dead when you are not
going to use the vehicle for long
periods of time, you need to check
and recharge the battery at least once
every three weeks. Make this check if
you perform short daily trips
(approximately 10 mi/16 km) which
correspond to an annual total of 4000miles/6000 km. Please note that
allowing the battery to go dead
repeatedly can cause premature wear
on the internal cells and greatly
reduce their life, leading to problems
with the ignition system and other
electrical/electronic systems.
TheAuthorized Maserati Dealeris
available to advise you on how to
recharge your battery correctly and
give you useful information on battery
care and maintenance.
NOTE:
TheAuthorized Maserati Dealercan
provide you with any information
about the Maserati approved “Battery
Charger and Conditioner”, available in
the “Genuine Accessories” range.
WARNING!
The process of charging or recharging
the battery produces hydrogen, a
dangerous gas that can explode and
cause serious injuries. When charging
or recharging the battery, follow the
recommended precautions at all
times:
•always charge or recharge the
battery in a well-ventilated
environment;•never charge or recharge a battery
that has frozen: it can explode due
to hydrogen trapped inside the ice
crystals;
•ensure that any sparks or open
flames are nowhere near the battery
while it is charging;
•before using a charger to charge or
maintain the battery charge status,
carefully follow the instructions
provided to ensure the charger is
connected to the battery safely and
correctly.
