SWITCHING OFF/ON THE
CLIMATE CONTROL
SYSTEM
Switching off the
climate control system
Press the
button (LED on button off).
With climate control off:
❒air recirculation is on, thus isolating
the passenger compartment from
the outside;
❒the compressor is off;
❒the fan is off;
❒the heated rear window can be
switched on or off;
❒the AQS (Air Quality System) function
(for versions/markets, where
provided) cannot be activated.
IMPORTANT The climate control
system control unit stores the
temperatures set before the system
was switched off and restores them
when any button of the system is
pressed (except for button D).Switching on the climate
control system
To switch on the climate control system
in fully automatic mode press the AUTO
button.
START&STOP
Automatic Climate
Control
The dual zone automatic climate control
manages the Start&Stop function
(engine off when the car speed is zero)
to guarantee a suitable comfort inside
the car.
Specifically, the Start&Stop function is
turned off when the weather is
particularly hot or cold to guarantee an
adequate level of comfort inside the
passenger compartment; therefore, the
engine will not be stopped during
these transient conditions, even if the
speed is zero.
When the Start&Stop function is active
(engine off at zero car speed), the
climate control system will request
restarting of the engine if the inside
temperature conditions rapidly
deteriorate (or if the user requests
maximum cooling – LO – or quick
demisting – MAX DEF).With the Start&Stop function on (engine
off at zero speed), air flow is reduced
to the minimum to maintain comfort
conditions inside the passenger
compartment as long as possible when
the system is in AUTO mode (LED N
on).
The climate control system control unit
attempts to manage the discomfort
caused by the engine stopping
(compressor and engine coolant pump
off) but operation of the climate control
system can be enhanced by turning
the Start&Stop off by pressing the
dedicated button on the dashboard.
NoteIn particularly severe climate
conditions it is recommended to limit
the use of the Start&Stop function
to prevent the compressor from
continuously switching on and off, with
consequent rapid misting of the
windows and accumulation of humidity
with unpleasant smells in the passenger
compartment.
NoteWhen the Start&Stop function is
on (engine off and vehicle speed zero),
the automatic recirculation
management is turned off always taking
air in from outside, to reduce the
probability of window misting up (as the
compressor is off).

ADDITIONAL HEATER
(for versions/markets, where provided)
This allows the passenger
compartment to be heated more
quickly in cold weather conditions. The
additional heater turns off automatically
after the required comfort conditions
are achieved.
Automatic dual zone
climate control system
(for versions/markets, where provided)
The additional heater activates
automatically depending on the
environmental conditions and with
engine started.
Manual climate control
system
The additional heater activates
automatically when knob A is turned to
the end of the red section and the fan
is set to at least 1
stspeed.
IMPORTANT The heater only works if
the outside temperature and engine
coolant temperature are low. The heater
will not activate if the battery voltage is
too low.
IMPORTANT
2) The climate control system
detects the passenger
compartment temperature with a
mean radiant temperature sensor
fitted in a cover under the internal
rear view mirror. Obstructing the
field of view of this sensor with
any object could cause the
climate control system to operate
with less than optimal efficiency
.

“FOLLOW ME HOME”
DEVICE
This device allows you to illuminate the
area in front of the car for a certain
amount of time.Activation
With the key turned to STOP or
removed, pull stalk A towards the
steering wheel within 2 minutes from
when the engine is turned off.
Each time the stalk is moved, the lights
stay on for an extra 30 seconds up to
a maximum of 210 seconds; then
the lights are switched off automatically.
Also, each time the stalk is operated,
the
warning light on the
instrument panel switches on. The
display shows the time set for the
function and the corresponding
graphics.
The warning light comes on when the

AUTOrain sensor activation (for
versions/markets, where
provided) (the windscreen wipers
adapt the operating speed
automatically to suit the intensity
of the rain)
intermittent operation;
continuous slow operation;
continuous fast operation.
Move the stalk upwards (unstable
position) to limit operation to the time
for which the stalk is held in this
position. When released, the stalk will
return to its default position and the
wiper will be automatically stopped.
"Smart washing"
function
Pull the lever towards the steering
wheel (unstable position) to operate the
windscreen washer. Keep the stalk
pulled for more than half a second to
operate the windscreen washer jet and
wiper automatically with a single
movement.
The wiper stops working three strokes
after the stalk is released. A further
stroke after approximately 6 seconds
completes the cycle.RAIN SENSOR
(for versions/markets, where provided)
This is an infrared LED sensor fitted
on the car windscreen fig. 33.
It is able to detect the presence of rain
and consequently manage windscreen
wiping in accordance with the amount
of water on the windscreen.
Activation
The sensor is activated when ring nut A
fig. 32 is turned to “automatic” position
(“AUTO” control): the windscreen wiper
stroke frequency is thus adjusted in
accordance with the amount of water
on the windscreen.
This frequency can vary from no stroke
(no rain - windscreen dry) up to the
2
ndconstant speed operation (heavy
rain - windscreen wet).The sensitivity of the rain sensor can be
adjusted through the Setup menu
(see paragraph “Menu Items” in the
“Knowing the instrument panel”
section).
If the engine is stopped with the lever in
“automatic” position, when it is next
started no wiping cycle will take place
even if it is raining. This prevents
accidental activation of the rain sensor
when the engine is started (e.g. when
the windscreen is being washed by
hand or the wipers are stuck to the
windscreen when there is ice).
To restore automatic operation of the
rain sensor, turn the ring nut on the
right stalk A fig. 32 from automatic
position (AUTO) toOposition and then
turn A ring nut back to the AUTO
position.
When the rain sensor is reactivated
using any of the manoeuvres described
above, reactivation is indicated by a
single stroke of the windscreen wipers,
regardless of the condition of the
windscreen.
If the sensitivity is changed whilst the
rain sensor is operating, a windscreen
wiper stroke is carried out to confirm
the change.

versions/markets, where provided,
message on the display are switched
on to indicate activation.
STORING THE CAR
SPEED
Proceed as follows:
❒turn ring nut A fig. 34 to ON and
press the accelerator to reach the
required speed;
❒move the stalk upwards (+) for at
least 1 second, then release it: the
car speed is now stored and you can
therefore release the accelerator.
If needed (when overtaking for
instance), you can accelerate simply by
pressing the accelerator; when you
release the pedal, the car goes back to
the speed stored previously.RESTORING THE
MEMORISED SPEED
If the device has been disengaged by
pressing the brake or clutch pedal, the
stored speed can be reset as follows:
❒accelerate gradually until a speed
approaching the one stored is
reached;
❒engage the gear selected at the time
that the speed was stored;
❒press the RES button (B fig. 34).
INCREASING THE
MEMORISED SPEED
This can be done in two ways:
❒by pressing the accelerator and
storing the new speed reached
or
❒by moving the stalk upwards (+) until
the new speed, which will be stored
automatically, is reached.
Each movement of the stalk
corresponds to an increase in speed of
about 1 km/h, while keeping the stalk
held upwards will continuously increase
the speed.REDUCING THE
MEMORISED SPEED
This can be done in two ways:
❒by deactivating the device and then
storing the new speed
or
❒by moving the stalk downwards (–)
until the new speed, which will be
stored automatically, is reached.
Each movement of the lever
corresponds to a slight reduction in
speed of about 1 km/h, while keeping
the stalk held downwards will decrease
the speed continuously.
TURNING THE DEVICE
OFF
The device can be deactivated in the
following ways:
❒by turning ring nut A fig. 34 to the
OFF position
❒by switching off the engine;
41

❒by pressing the brake pedal, the
clutch or the accelerator; in this
last case the system is not effectively
deactivated but the system gives
priority to the acceleration request.
The device still remains active,
without the need to press the RES
button to return to the previous
conditions once acceleration
is concluded.
Automatic deactivation
The device deactivates automatically in
the following cases:
❒if the ABS or ESC systems intervene;

ESC SYSTEM
IN BRIEF
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by
the engine can also be reduced in
order to maintain control of the car.
30) 31) 32) 33) 34)
The ESC system uses sensors installed
on the car to determine the trajectory
that the driver intends to follow and
compares it with the car’s effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
car’s understeer or oversteer.
❒Oversteer: occurs when the car is
turning more than it should according
to the angle of the steering wheel.
❒Understeer: occurs when the car is
turning less than it should according
to the angle of the steering wheel.The ESC system also includes the
following systems:
❒EBD
❒ABS
❒CBC
❒ASR
❒HILL HOLDER
❒HBA
❒MSR
❒DST
❒“ELECTRONIC Q2” (“E-Q2”)
❒"PRE-FILL" (RAB - Ready Alert
Brake)
SYSTEM ACTIVATION
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
SYSTEM INTERVENTION
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.EBD SYSTEM
The EBD system is an integral part of
the ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear
wheels.
This guarantees greater braking stability
for the car, preventing sudden locking
of the rear wheels and the consequent
instability of the car.
ABS
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the car
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes when braking
and the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.
