General

The vehicle is equipped with an 
automatic dual-zone air conditioning 
system. 
This systems adjusts the air 
temperature, distribution and flow in 
the passenger compartment, in two 
separate zones: left-hand side and 
right-hand side.
Through the panel incorporated 
in the center console the user can 
control the following parameters/
functions:
-  left-hand/right-hand vent air 

temperature

-  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/demisting 

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.

The system is equipped with a 
demisting system which, by means 
of a sensor (positioned behind the 
internal rear-view mirror) “checks” 
a predefined surface area of the 
windshield and automatically 
activates a special strategy to prevent 
or reduce misting up. The sensor can 
be disabled by operating any system 

control when the strategy is active. 
The sensor is enabled upon ignition 
and whenever the user presses one of 
the buttons 10 AUTO.

WARNING: To ensure proper 
functioning of the 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.

127

Activation

The system can be started up in 
a number of ways. It is however 
advisable to begin by pressing one 
of the buttons 10 AUTO and using 
the buttons 1 or 2 to 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 

button 

7 adjusts the air 

temperature and distribution in the 
two heating/air conditioning areas.

- REAR 

button 

12 enables/disables 

the air flow to the rear vents

- button 

6 turns off the compressor

- button 

8 activates/deactivates the 

defrosting/demisting function on 
the front side windows

- button 

11 activates/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 in the following.

System deactivation (OFF function)

If the compressor is deactivated by 
setting the fan speed control 3 below 
the first bar, the A/C system will be 
turned off.
When set to OFF, the heated rear 
window button 11 and recirculation 
button 9 are controlled normally 
without activating the air 
conditioning system.
Exiting the OFF mode, the 
recirculation function will switch back 
to Automatic mode. 
To reactivate the A/C system when 
OFF select one of the following 
options:
-  fan speed ‘’+’’;
- A/C 

compressor;

- MAX 

DEF;

- AUTO.

Recirculation
This function is activated by pressing 
button 9 and allows only the air 
already in the passenger compartment 
to circulate. 
The recirculation function has various 
operation modes:
-  Forced closed recirculation (LED on 

button illuminated)

-  Forced open recirculation (LED on 

button off).

128

Automatic mode 
When the compressor is deactivated 
or outside temperatures are 
below 37.4 °F (3˚C), the automatic 
recirculation function is deactivated 
automatically.
After prolonged operation (over 
15 minutes in a row), the system 
deactivates the recirculation function 
automatically for safety reasons, 
allowing the exchange of air once 
again.

Forced closed recirculation
In this operating mode, the 
illumination of the amber LED 
indicates that the recirculation vent is 
closed.

Forced open recirculation
In this operating mode, the LED 
turned off indicates that the outside 
air vent is opening.

AUTO mode

When this button is pressed (one 
button per zone), automatic mode 
will control the following functions 
once again:
-  air distribution (for the side 

concerned)

- fan 

speed

-  compressor operation (illumination 

of the ECON LED)

- air 

recirculation.

REAR mode

Press the button REAR 12 (relative LED 
illuminated) to: 
-  Open/close the air flow to the rear 

vents.

This function is active in both 
“MONO” and “DUAL-ZONE” modes.

System initialization

Every time the battery is reconnected, 
when the vehicle is started the system 
must be initialized by activating the 
compressor. The display automatically 
shows the passenger compartment 
temperatures set to 71.6 °F (22˚C).
The system is configured as follows:
-  AUTO (automatic operation, the 

words “FULL AUTO” appear on the 
display). 

-  Compressor enabled (the LED on 

the button is illuminated).

- Defrosting/demisting 

function 

(MAX DEF) deactivated (the LED on 
the button is off).

-  Heated rear window deactivated 

(the LED on the button is off).

- Open 

recirculation. 

-  Air ventilation and distribution are 

set by the system. 

-  REAR disabled (the LED on the 

button is off), the air flows to the 
rear vents.

133

If the engine does not start after a 
number of attempts, do not continue 
but consult your Authorized Maserati 
Dealer.

Do not perform this 
procedure if you are 
unexperienced: incorrect 

maneuvers can cause high electrical 
discharges and can even cause the 
battery to explode.

You are also advised not to 
approach the battery with 
open flames or lit cigarettes 

and not to cause sparks: Risk of 
explosion and fire! 

WARNING: Never use a battery-
charger for emergency starting 
under any circumstances: you could 
damage the electronic systems and 
in particular the ECUs that control 
ignition and fuel supply functions.

Remember that when the 
engine is not started, the 
brake servo and power 

steering systems are not functioning 
and therefore the effort required on 
the brake pedal and steering wheel is 
much greater.

Turning off the engine

With the engine idling, turn the 
ignition key to STOP (OFF).
A burst on the accelerator pedal 
before turning off the engine has 
no purpose and increases fuel 
consumption.

WARNING: The ignition key can only 
be removed from the switch when 
the gearshift lever is in position P 
and within 30 seconds after turning 
the key to STOP (OFF). If you do not 
remove the key within 30 seconds, 
you will need to turn it back to MAR 
(ON) and then to STOP (OFF) to have 
a further 30 seconds within which to 
remove the key. 

In the event that the key unlocking 
system fails or if it is not possible 
to shift the gearshift lever to P, to 
remove the key you must turn it to 
STOP (OFF), then remove the cap A 
using a pen or sufficiently pointed 
tool, then press the button just 
uncovered and at the same time 
extract the key. Once the key has 
been removed, refit the cap A.

Electronic automatic 
gearbox

The electronically-controlled gearbox 
has six forward gear ratios and one 
reverse gear. The gears can also be 
engaged manually once you have 
shifted the gearshift lever to the 
sector provided.
The gearbox controls are the 
following:
A  - gearshift mode selection lever;
B  - button on the gearbox lever to 

engage R (Reverse) and P (PARK);

C - button SPORT;
D - button ICE (low grip);
E - gear display.

The SPORT and ICE modes can be 
selected both when the gearbox 
is set to automatic (AUTO) and 
to sequential manual (MANUAL) 
operation.

The gearbox operating mode is 
controlled by the lever A.
This lever can be moved to the 
following positions:
P – (PARK)
R – (REVERSE)
N – (NEUTRAL)
D – (DRIVE) 
+ / - – (MANUAL)
The position of the gearshift lever A 
is shown on the gear display E by the 
illumination of the corresponding 
letter. This letter is also shown on the 
instrument panel display.

WARNING: In order to correctly use 
the automatic gearbox, it is essential 
that you first read through this whole 
chapter so that you can learn which 
operations are correct and permitted.

The gearbox is also equipped with 
Shift-Lock and Key-Lock safety 
systems.

Shift-Lock

This safety system allows you to shift 
from P (PARK) to another position 
only if the brake pedal is depressed. 
This prevents the vehicle from 
involuntarily jumping forward or 
backward.

Key-Lock

This function allows you to remove 
the key from the ignition switch 
only when the gearshift lever A is 
in position P and within a maximum 
time of 30 seconds; when this time 
has elapsed, the key can no longer be 
removed.

be moved to position P only when 
the ignition key is in the MAR (ON) 
position and the button B and the 
brake pedal are pushed (Shift-lock 
safety).

For safety reasons, the gearshift lever 
A can be moved from position D to 
positions R and P only when button 
B is pushed. It is also advisable to 
depress the brake pedal during this 
maneuver.

WARNING: Do not run the engine at 
top RPM until it has reached stable 
operating temperature.

WARNING: In the case of performance 
starting, check that the electric 
parking brake is disengaged.

Do not keep the vehicle 
stationary for a long time 
with the brake pedal 

depressed, the gearshift lever in D 
and the engine running, as this may 
lead to malfunctions.

WARNING: For more comfortable 
starting (with the gearshift lever in D, 
R or Manual and the electric parking 
brake - EPB - engaged), push the 
brake pedal, manually deactivate the 
EPB system by pulling up the lever F, 
and push the accelerator pedal. 

Hill Holder Strategy

The Hill Holder system helps the driver 
when starting-off on uphill slopes. 
It activates only following a vehicle 
stop when the brake pedal is released, 
keeping the vehicle stationary for 
a moment, so as to allow the driver 
to move his foot from the brake to 
the accelerator pedal. The system is 
activated on slopes with a gradient of 
more than 15°.

Stopping the vehicle

Regardless of the position of the 
gearshift lever A, you must only 
depress the brake pedal to stop the 
vehicle. 

When the gearshift lever is 
in position D, R or MANUAL, 
the engine idling and the 

vehicle on an even surface, if the 
brake pedal is not depressed, the 
vehicle can move.

The ignition key can be removed from 
the switch only when the gearshift 
lever A is in position P and within 30 
seconds from turning the key to STOP 
(OFF). The letter P (Key-Lock safety) is 
displayed on the instrument panel for 
this entire time. 
If you do not remove the key within 
30 seconds, you will need to turn it 
back to MAR (ON) and then to STOP
