Left Turn Signal Indicator Light
The indicator lights up when
the left turn signals or the
hazard flashers are turned on.
The indicator light will flash at
the same frequency of the turn signals
and is controlled by the left
multifunction lever.
If the vehicle electronics sense that the
vehicle drives for more than 1 mile
(1.6 km) with either turn signal on, a
continuous sound will alert the driver
to turn the signal off.
If the indicator flashes at a rapid rate,
check for a defective exterior light
bulb.
Rear Fog Light Indicator
This indicator lights up when
the rear fog lights are
switched on.
Tire Pressure Monitoring Light (*)
This indicator light is
connected to the Tire Pressure
Monitoring System (TPMS).
Under normal conditions, the
warning light should illuminate when
the key in the ignition switch is in
MAR (ON)position and should go off
as soon as the engine is started.
If the warning light remains lit or
illuminates while driving, the pressureof one or more tires is too low: the
related message will be displayed.
If the warning light flashes prior to
remain on, it indicates that the system
is temporarily unavailable.
This warning light illuminates even
when you calibrate the TPMS and
remains lit until the system is
calibrated.
Please refer to “Tire Pressure
Monitoring System (TPMS)” in section
“Driving” for further information.
Telltales on Tachometer
Following telltales are displayed on
the tachometer and related messages

WARNING!
Maserati urges you to use the seat
belts correctly fastened and adjusted
at all times. Correct use of the seat
belts can help reduce the risk of
serious injury in the event of an
accident. Do not pass seat belts over
sharp edges: they could tear. Do not
pin anything to the seat belts. This

• left-hand/right-hand vent air
distribution;
• fan speed (stepless change);
• compressor activation;
• air recirculation.
All the functions listed above can be
modified manually, i.e. the user can
select one or more of these functions
as desired, using the control panel.
The manual selections always have
priority over the automatic ones and
are memorized until the user chooses
the automatic control again.
When a function has been set
manually, the other automatic
functions will not be affected.
The following parameters/functions
can be set/modified manually:
• left-hand/right-hand side air
temperature;
• fan speed;
• air distribution on 7 positions
(left-hand/ right-hand);
• compressor activation;
• single/dual-zone distribution priority;
• defrosting/defogging function (MAX
DEF);
• air recirculation;
• automatic/manual control of the
system;
• heated rear window;• system deactivation;
• opening/closing of air duct leading
to rear vents.
Activation
The system can be started up in a
number of ways. It is however
advisable to begin by pressing one of
the buttons10AUTO and using the
buttons1or2to set the desired
temperature. This way the system will
operate in fully automatic mode so
that the temperatures set will be
reached as quickly as possible.
In this condition, manual operations
will activate the following functions:
• MONO button7adjusts the air
temperature and distribution in the
two heating/air conditioning areas;
• REAR button12enables/disables the
air flow to the rear vents;
• button6turns off the compressor;
• button8activates/deactivates the
defrosting/defogging function on
the front side windows;
• button11activates/deactivates the
heated rear window.By altering any other parameter
manually, such as the air temperature
or distribution, these features switch
from the fully automatic control mode
(FULL AUTO) to manual mode (AUTO).
On starting the vehicle after stopping,
the various parameters are controlled
manually or automatically, depending
on the options selected by the user
before turning the engine off.
Therefore all the manual operations
performed before the vehicle is turned
off are stored and maintained for the
next start up.
This also applies to the OFF function
described below.

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

vehicle
When you open a door to get into the
car, the instrument cluster turns on.
The TFT displays the complete
odometer, time, outside temperature
and the
open doors indicator.
Before starting the engine, close the
doors, adjust your seat, the inside and
outside mirrors, fasten your seat belt
and instruct all other occupants to
buckle their seat belts.
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.
Press the brake pedal and turn the key
in the ignition switch toMAR (ON)
position.
Instrument cluster displays the initial
sequence with warning light and
analog instruments test routine.
Turn the key intoAVVposition and
release it when the engine starts. The
key will return toMAR (ON)position
automatically.
Do not hold the key inAVVposition
for a long time.
If the engine fails to start, the starter
will disengage automatically after 10
seconds. If you wish to stop the
cranking of the engine prior to
starting it, turn the key toSTOP (OFF)
position.
If the engine does not start, turn the
key toSTOP (OFF)position and wait
for the gear display to go off. Then
repeat the entire procedure.
NOTE:
Normal starting of either a cold or a
warm engine is obtained without
pumping or pressing the accelerator
pedal.

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.
