To adjust the analog clock located on
the center of the dashboard above the
MTC+ display, use the MTC+ System
(see “MTC+ Settings” in this section).
The time can be visualized also on the
MTC+ status bar and on the
instrument cluster display (see “MTC+
Settings” in this section).
Clock lighting is aligned with the
backlighting status of the MTC+
display (refer to “MTC + Settings” in
section “Dashboard Instruments and
Controls”).
Air Conditioning Controls
The vehicle is equipped with an
automatic dual-zone air conditioning
system that allows to adjust separately
the air temperature and the airflow
distribution in the left and in the right
zone of the passenger compartment,
according to the requests of the driver
and the front passenger.
A humidity sensor, positioned on the
inner surface of the windshield, over
the rearview mirror, allows the A/C
system to prevent/ eliminate fogging
of the windshield and side windows.
The best efficacy in preventing
fogging is obtained by selecting the
AUTO function, described later.
A dual zone solar sensor, positioned on
the center of the dashboard upper
surface, helps to achieve the best
comfort in presence of solar radiation.
CAUTION!
To ensure proper functioning of the solar
sensor, do not apply adhesive parking
stickers, etc. in the checking area
between the sensor and the windshield.
Therefore, keep the windshield and the
sensor clean to prevent accumulation of
dust or other impurities.

Normal Starting of the
Engine
WARNING!
It is dangerous to run the engine in an
enclosed area. The engine consumes
oxygen and discharges carbon
dioxide, carbon monoxide and other
toxic gases in the atmosphere.
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-

Make sure that the Electric Parking
Brake (EPB) is applied.
The shift lever must be in P (Park) or N
(Neutral) position before you can start
the engine. Apply the brakes before
shifting into any driving gear (see
“Automatic Transmission” in this
section).
CAUTION!
• Before starting the engine, switch off
the electrical devices with a high
power consumption (air-conditioning
and heating system, heated rear
window, headlights, etc.).
• Do not start the engine if the fuel
level in the tank is low.

asphalt is significantly reduced. This
means that braking distances increase
considerably and road grip decreases.
Some advices for driving in the rain
are listed below.
• Reduce your speed and keep a
greater safety distance from the
vehicles in front of you. High speed
may result in a loss of vehicle
control.
• When driving on wet or slushy roads,
it is possible for a wedge of water to
build up between the tire and road
surface. This is known as
aquaplaning and may cause partial
or complete loss of vehicle control
and stopping ability. To reduce this
possibility: slow down if the road has
standing water or puddles.
• Heavy rain substantially reduces
visibility. In these circumstances, even
during the day, turn on the low
beams, to be more visible to other
drivers.
• Set the air conditioning and heating
system controls on the defogging
function, in order to avoid any
visibility problem.
• Periodically check the conditions of
the windshield wiper blades.• In low grip conditions use “ICE”
drive mode (see chapters “Drive
Mode” in this section).
Driving in Fog
If the fog is dense, avoid traveling if
possible.
When driving in mist, blanket fog or
when there is the possibility of banks
of fog, please consider some advices
listed below.
• Keep a moderate speed.
• Even in daytime, turn on the low
beams and rear fog lights. Do not
use the high beams.
• Remember that fog creates
dampness on the asphalt and thus
any type of maneuver is more
difficult and braking distances are
extended.
• Keep a safe distance from the
vehicle in front of you.
• Avoid sudden changes in speed as
much as possible.
• Whenever possible, avoid
overtaking.
• If you are forced to stop the vehicle
(breakdowns, impossibility of
proceeding due to poor visibility,
etc.), first of all, try to stop off of the
travel lane. Then turn on the hazardwarning flashers and, if possible, the
low beams.
• Sound the horn rhythmically if you
hear another vehicle approaching.
• When you get out of the vehicle, put
on the high-visibility vest (if
equipped).
CAUTION!
Be aware that rear fog lights can
bother the drivers following your
vehicle: when visibility is back to
normal, turn off these lights.
Driving in the Mountains
Mountain roads usually have many
narrow turns and curves, tunnels and
steep uphill or downhill slopes: please
consider some advices listed below.
• Drive at a moderate speed, avoid
“cutting” corners.
• When driving inside a tunnel in
daylight turn on the low beams in
advance; avoid high beams and be
aware of the rapid brightness
change. Avoid abrupt maneuvers
that could be dangerous for the
following vehicle.
• Never coast downhill with the
engine off or in neutral, and never

Maintenance Procedures
The following pages contain the
“required” maintenance standards
determined by Maserati engineers.
Besides those maintenance items
specified in the “Scheduled Service
Plan”, there are other components
which may require service or
replacement in the future.
To perform most of the services, it is
necessary to open the hood (see
“Open and Close the Hood” in section
“Before Starting”).
The following images show the
position of all components involved in
the maintenance service.
CAUTION!
• Failure to properly maintain your
vehicle or perform repairs and
service when necessary could result
in more costly repairs, damage to
other components or negatively
impact vehicle performance.
Immediately have potential
malfunctions examined by an
Authorized Maserati Dealeror a
qualified repair center.
• Your vehicle has been equipped with
improved fluids that protect the
performance and durability of yourvehicle and also allow extended
maintenance intervals. Do not use
chemical flushes for washing as the
chemicals can damage your engine,

quick coupling from the negative
pole (–) of the battery.
If the battery needs to be removed
from its compartment, you must first
detach the terminal clamp from
negative pole (–) and then the other
terminal clamp from positive pole (+),
after removing the protective cover.
Battery poles are marked positive (+)
and negative (–) and are identified on
the battery case.
Remove the metal clamp indicated in
the picture and then remove the
battery from the trunk compartment.
To Reconnect the Battery
NOTE:
When the battery cables have been
disconnected and the trunk lid has
been locked, it is necessary to pull the
emergency release cable in order to
re-open it. To access the trunk and
operate the emergency release (see
“Open and Close the Trunk Lid”
chapter in section “Before Starting”).
CAUTION!
• It is essential when replacing the
cables on the battery that the
positive cable is precisely attached to
the positive pole (+) and the
negative cable is attached to the
negative pole (–).
• Cable clamps should be tight on the
terminal poles and free of corrosion.
After the battery has been
disconnected and re-connected and
before starting the engine it is
necessary to proceed as follows:
• Unlock and lock the doors using the
radio control buttons on the key.
• Unlock the trunk lid with the radio
control button on the key and then
lock it manually.• Check the seats are working
correctly: in the event of
malfunction, carry out the
initialization operations described in
the chapter “Front Seats” of the
section “Understanding the Vehicle”.
• Initialize the climate control system
by activating the compressor as
described in chapter "Air
Conditioning Controls" of the section
“Dashboard Instruments and
