It is switched on by setting a tempera-
ture lower than 16°C on the display;
this setting is shown on the display. This
function can be switched on when you
wish to cool the passenger compartment
as quickly as possible, by taking the
greatest advantage from the system po-
tential.
The function cuts off air heating, switch-
es on both internal air recirculation (to
prevent hot air from entering the com-
partment) and the climate control com-
pressor, brings air distribution to
¯/˙
and the fan speed is controlled auto-
matically by the system. With the function switched on, howev-
er, all the manual settings can be made.

that supports the engine during cold or
winter weather to quickly reach a com-
fortable temperature in the passenger
compartment.
The additional heater works with the en-
gine running when the outside temper-
ature is below 20°C and the engine has
not yet reached normal operating tem-
perature. After connecting/dis-
connecting the battery,
wait for 3 minutes at
least before fitting the electronic
key into the ignition device in

“FOLLOW ME HOME”
DEVICE
This function allows the illumination of
the space in front of the car for a pre-
set period of time.
Activation
Pull the stalk towards the steering wheel
within 2 minutes from when the engine
is turned off.
At each single movement of the stalk,
the staying on of the lights is extended
by 30 seconds up to a maximum of 3.5
minutes; then the lights are switched off
automatically.
Each time the stalk is operated, the
3
warning light turns on together with the
message on the display (see section
“Warning lights and messages”).
Deactivation
Keep the stalk pulled towards the steer-
ing wheel for more than 2 seconds.
AUTOMATIC HEADLIGHTS
SENSOR (daylight sensor)
(where provided)
It detects the changes of the external
light intensity of the car according to the
light sensitivity set: the greater the sen-
sitivity is, the smaller the amount of ex-
ternal light necessary to control the
switching-on of the external headlights
will be.
On certain versions, the daylight sen-
sor sensitivity can be adjusted through
the “Setup Menu” of the display (see
section “Reconfigurable multifunction
display” in this section).
Activation
Turn the knurled ring A-fig. 51to
2A:
in this way, the automatic activation of
the side/taillights and dipped beam
headlights is simultaneously enabled ac-
cording to outside brightness.
With lights switched on automatically
and in the presence of a switching off
control by the sensor, the main beams
will be switched off first and a few sec-
onds after also the sidelights.Deactivation
As a result of the sensor control, the
dipped beam headlights will switch off
and, after a few seconds, sidelights will
switch off too. The sensor is not able
to detect the fog presence, under this
condition lights shall therefore be
switched on manually.
Failure warnings
On certain versions headlight sensor fail-
ure is shown by the instrument panel
warning light
1, whereas on other ver-
sions a dedicated message is shown on
the display (see section “Warning lights
and messages”).

Turning the knurled ringA-fig. 54it
is possible to increase the sensitivity of
the rain sensor, obtaining a quicker
change from stationary (no wiping)
when the windscreen is dry, to first con-
tinuous speed (continuous, slow). A fur-
ther stroke will confirm operation.
Operating the windscreen washer with
the rain sensor activated (stalk at posi-
tion1-fig. 54) the normal washing
cycle is performed at the end of which
the rain sensor resumes its normal au-
tomatic function.
Removing the electronic key from the
ignition device, the rain sensor is deac-
tivated and the next time the engine is
started it will not be reactivated even if
the stalk has remained in position 1-
fig. 54. In this case to activate the rain
sensor, simply move the stalk to 0or2
and then back to 1.
When the rain sensor is reactivated in
this way, the wiper performs one stroke,
even if the windscreen is dry, to indicate
that reactivation has occurred. “Smart washing” function
Pulling the lever towards the steering
wheel (unstable position) operates the
windscreen washer.
Keeping the stalk pulled with just one
movement it is possible to operate the
washer jet and the wiper at the same
time; the wiper actually comes into op-
eration automatically when the stalk is
pulled for more than half a second.
The wiper stops working 3 strokes after
releasing the stalk; a further stroke af-
ter about 6 seconds will complete the
wiping operation.
RAIN SENSOR
(where provided)
The rain sensor A-fig. 55, located be-
hind the driving mirror, is an electronic de-
vice combined with the windscreen wiper
which has the purpose of automatically
adjusting the number of wipes to intensi-
ty of the rain. All the other functions con-
trolled by the right-hand stalk remain un-
changed.
The rain sensor is activated automati-
cally moving the right-hand stalk to po-
sition1-fig. 54and it has a range of
adjustment that gradually varies be-
tween wiper stationary (no wiping)
when the windscreen is dry, to wiper
at second speed (continuous, medium
wiping) with heavy rain.
