• 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

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

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 149-158°F (65-70°C).
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.

Automatic Transmission
The electronic shift lever replaces the
conventional mechanical lever and has
no mechanical connection to the
transmission. The transmission is
operated by electrical actuators on the
hydraulic system and all commands to
the control system are transmitted by
the CAN network.
The automatic transmission has six
forward gear ratios and one reverse
gear. The gears can also be engaged
manually once you have shifted the
transmission shift lever to the sector
provided.
CAUTION!
In order to properly use the automatic
transmission, it is essential that you
read through the whole chapter, so
that you can understand right from
the start what the correct and
permitted operations are.
Damage to the transmission may occur
if the following precautions are not
observed:
• Shift into P (Park) only after the
vehicle has come to a complete stop.
This is the default position of the
lever and should be used every timethe key in the ignition switch is
turned toSTOP (OFF)position.
• Shift into or out of R (Reverse) only
after the vehicle has come to a
complete stop and the engine is at
idle speed.
• Do not shift between P (Park), R
(Reverse), N (Neutral) or D (Drive)
when the engine is above idle speed.
• To effect any change from vehicle
stop to R (Reverse), D (Drive), 1
stor
2ndgear, it is necessary to keep the
brake pedal fully depressed.
WARNING!
•It is dangerous to move the shift
lever out of P (Park) or N (Neutral) if
the engine speed is higher than idle
speed. Only shift into gear when the
engine is idling normally and when
your foot is firmly pressing on the
brake pedal.
•As with all vehicles, you should
never exit a vehicle while the engine
is running. Before exiting a vehicle,
always apply the electronic parking
brake, shift the transmission into P
(Park), and turn the engine off.
•When leaving the vehicle, always
remove the key from the ignitionswitch and lock your vehicle.
•Do not leave the key in or near the
vehicle.
The transmission system is equipped
with "Shift-Lock" and "Key-Lock"
safety functions.
Shift-Lock
This safety function 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 transmission shift lever is in
P (Park) position and within a
maximum time of 30 seconds. When
this time has elapsed, the key can no
longer be removed.
Automatic Transmission Lever
Automatic transmission is operated by
a lever with unlock button to engage
R (Reverse) and P (Park) located on the
central console.
By using the transmission shift lever it
is possible to select following
positions, indicated on the gear display
at the side of the transmission shift

lever. The selected position will
illuminate in white light.
• P (Park);
• R (Reverse);
• N (Neutral);
• D (Drive) automatic forward speed (6
ranges);
• –/+ to downshift or upshift in
sequential manual mode (see "Drive
Mode" in this section).
Transmission status (example shown in
picture: D (Drive)) is visible also on the
central part of the instrument cluster
display.Starting the Engine
The engine can only be started when
the transmission shift lever is in P
(Park) or N (Neutral) position.
WARNING!
Always start the engine holding the
brake pedal depressed.
NOTE:
After starting the engine and setting
off, do not depress the accelerator
pedal before and while shifting the
transmission shift lever. This is
particularly important when the
engine is cold.
Driving the Vehicle
After starting the vehicle, with the
engine idling and the brake pedal
depressed (“Shift-Lock” safety), movethe transmission shift lever to D
(Drive) position or in the position for
sequential manual shifting “+” or “–”.
Release the brake pedal and gradually
depress the accelerator pedal.
NOTE:
The transmission shift lever can be
moved to P (Park) position only when
the key in the ignition switch is in the
MAR (ON)position and both the
unlock button on the transmission
lever and the brake pedal are pushed
(Shift-lock safety).
For safety reasons, the transmission
shift lever can be moved from D
(Drive) position to R (Reverse) and P
(Park) position only when unlock
button on the transmission shift lever
is pushed. It is also advisable to
depress the brake pedal during this
maneuver.
NOTE:
•Do not run the engine at top RPM
until it has reached stable operating
temperature.
•In the case of performance starting,
check that the Electric Parking Brake
