Engine Overheating
To reduce potentially overheating of
the engine in city traffic, while
stationary, place the transmission in N
(Neutral), but do not increase the
engine idle speed.
NOTE:
There are steps that you can take to
slow down an impending overheat
condition:
•If your air conditioner (A/C) is on,
turn it off. The A/C system adds heat
to the engine cooling system and
turning the A/C off can help remove
this heat.
•You can also turn the temperature
control to maximum heat, the mode
control to floor and the blower
control to high. This allows the
heater core to act as a supplement to
the radiator and aids in removing
heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system
could damage the engine. If the
temperature gauge is positioned on
the red zone (refer to “Instrument
Cluster” in section “DashboardInstruments and Controls”), pull over
and stop the vehicle. Idle the vehicle
with the air conditioner turned off
until the temperature gauge drops
back into the normal range. If the
temperature gauge remains on the red
zone turn the engine off immediately
and contact theAuthorized Maserati
Dealer.
WARNING!
You or others can be badly burned by
hot engine coolant (antifreeze) or
steam from your radiator. If you see or
hear steam coming from under the
hood, do not open it until the radiator
has had time to cool.
Never try to open a coolant bottle
pressure cap (refer to “Maintenance
Procedures” in section “Maintenance
and Care”) when the radiator is
overheated.
In case of a Punctured Tire
The vehicle can be equipped with a
tire repair kit or with a compact spare
wheel.
Using Tire Repair Kit
Small punctures up to 1⁄4” (6 mm) in
the tire tread can be sealed using the
tire repair kit, fitted beneath the floor
panel of the trunk compartment.
The kit comes in a bag and consists of
two parts:
• an electric compressor with pressure
gage, hose to be connected to the
punctured tire and power cable;
• a gas cylinder containing sealant.

• Place the jack near the wheel to be
changed in one of the indicated
positions.
• Make sure that the head of the jack
is correctly inserted in one of the
slots beneath the sole bar.
WARNING!
•Never position yourself under a
jacked vehicle.
•The lifted vehicle may fall and
damage the vehicle's body if the
jack is not positioned correctly.
•Never use the jack to carry out
maintenance or repairs under the
vehicle.
• Turn the jack lever until the wheel is
raised a few centimeters off the
ground.
• Completely unscrew the five bolts
and remove the wheel. In case a
“Wheel Security Stud Bolt” is
installed, it can only be removed by
using the specific fitting wrench
provided with the “Wheel Security
Stud Bolt Kit”, available in the
Genuine Accessories range.
• Fit the compact spare wheel with the
valve stem facing outward, securing
it with the five bolts previously
removed.
• Turn the lever of the jack to lower
the vehicle and remove the jack.
• Fully tighten the bolts, alternately

Jump-Start Procedure
WARNING!
•The battery is secured to the vehicle
with a metal clamp (indicated in the
picture), so be extremely careful not
to let the clips on the end of the
cables come into contact with it.
•Remove any metal jewelry such as
watch bands or bracelets that might
make an inadvertent electrical
contact. You could be seriously
injured.
•Do not allow the vehicles involved
in the jump-starting operation to
touch each other as this could
establish a ground connection and
cause personal injury.
• Turn off the heater, radio, and all
unnecessary electrical accessories.
• Set the parking brake, shift the
automatic transmission into P (Park)

parking brake and make sure the
ignition is off.
• Connect one terminal clamp of the
positive jumper cable to the positive
(+) pole of the discharged battery.
• Connect the opposite terminal clamp
of the positive (+) jumper cable to
the positive (+) pole of the booster
battery.
• Connect one terminal clamp of the
negative jumper cable to the
negative (–) pole of the booster
battery.
• Connect the opposite terminal clamp
of the negative (–) jumper cable to
the negative (–) pole of the
discharged battery.

Scheduled Maintenance
Service
Correct maintenance is clearly the best
way to guarantee vehicle performance
and safety features, ensure respect for
the environment and low operating
costs.
NOTE:
Also remember that the scrupulous
observance of the maintenance
procedures is essential for keeping
your vehicle operating properly. Not
adhering to the “Scheduled Service
Plan” can impact your vehicle’s
warranty.
Interval Running Coupons
Maserati has therefore provided for a
series of checks and maintenance
operations involving the 1
stservice
when the vehicle mileage reaches
12500 mi (20000 km) or after 2 years of
the vehicle's life, and subsequently
every 12500 mi (20000 km) or every 2
years.
After the 12
thservice, maintenance
must be restarted with the operations
scheduled for the 1
st,2ndand 3rd

when a service is performed, further
replacements or repairs are found to
be necessary in addition to the
scheduled operations, these can be
carried out only with the specific
consent of the Customer.
CAUTION!
You are advised to notify the
Authorized Maserati Dealerof any
minor operating problem, without
waiting for the next scheduled service.
NOTE:
•Change your vehicle's oil if it has
been 2 years since your last oil
change.
•Change your engine oil more often if
you drive your vehicle off-road for an
extended period of time or shorttrips without reaching operation
temperature.
•Under no circumstances should oil
change intervals exceed 12500 mi
(20000 km) or at least after 2 years.
CAUTION!
Failure to perform the required
maintenance items may result in
damage to the vehicle.
Scheduled Maintenance
(Service) Indicator
When the deadlines for maintenance
Scheduled Maintenance services are
approaching, a message on the
instrument cluster display indicates
that service is due. The deadline may
be expressed in miles/Km or days,
whichever comes first.
The message is displayed only once,
upon activating the instrument cluster,
at decreasing intervals expressed in
mi/km (100, 50...... 1800, 1600,) or in
days (27, 24, ....... 6, 3), accompanied
by the
specific symbol.

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.
