START&STOP
Manual climate control system
The system will remain set to the air flow setting made by the user
when the Start&Stop function is operated (engine off when speed
is zero). Cooling and heating in the passenger compartment is not
guaranteed in these conditions because the compressor and the
engine coolant pump are both stopped. To privilege climate con-
trol system operation, press the button on the dashboard to turn
the Start&Stop function off.
NOTAIn particularly severe climate conditions it is recommended
to limit the use of the Start&Stop function to prevent the com-
pressor from continuously switching on and off, with following fa-
st window misting and accumulation of humidity with unpleasant
smells in the passenger compartment.
SYSTEM MAINTENANCE
Operate the climate control system for at least 10 minutes every
month during the winter. Have the system checked by Alfa Romeo
Authorized Services before the summer.

Four other positions are provided (see diagram below):
v(A Position) Air flow distribution between centre/side dash-
board vents, rear vent and windscreen and front side window
demisting/defrosting vents. This distribution setting ventilates
the passenger compartment and prevents the windows from
misting up.
u(B Position) Air flow distributed between foot well vents and
windscreen and front side window defrosting/demisting vents.
This distribution setting allows warms up the passenger com-
partment and prevents the windows from misting up.
w(C Position) Air flow distribution between footwell vents
(warmer air) and centre/side dashboard vents and rear vent
(cooler air).
-(D Position) Automatic demisting/defrosting activation (see
description of the previous pages).

CLIMATE CONTROL SYSTEM COMPRESSOR
Press C to turn the compressor on/off (the LED on the button will
light up when the compressor is on). The system remembers that
the compressor has been switched off, even after the engine has
stopped.
When the compressor is switched off the system deactivates air re-
circulation to prevent the windows from misting up and deactivates
the AQS function. In this case, although the system is capable of
maintaining the required temperature, the AUTO LED will go out.
The temperatures will flash for a few seconds if the required tem-
perature cannot be maintained.
To restore automatic control for switching on the climate control
compressor, press C button again or press the AUTO button.
With compressor off:
❍if the outside temperature is higher than the set one, the sys-
tem will not be able to satisfy the request. The temperature
value will then flash on the display for a few seconds;
❍the fan speed can be manually reset.
When the compressor is on and the engine is running, manual ven-
tilation cannot drop under the maximum speed (only one LED on).
IMPORTANT With the climate control compressor off, it is not pos-
sible to admit air into the passenger compartment with a tempera-
ture below the outside temperature; moreover, under certain envi-
ronmental conditions the windows could mist up very quickly since
the air cannot be dehumidified.
RAPID WINDOW DEMISTING/DEFROSTING
(MAX-DEF function)
Press-to turn windscreen and side window demisting/defrosting
function on (LED on button lit). The climate control system carries
out the following operations:
❍switches on the climate control compressor when climatic con-
ditions allow;
❍turns air recirculation off;
❍sets maximum air temperature (HI) in both zones;
❍sets proper fan speed according to the engine coolant tem-
perature;
❍directs air flow to the windscreen and front side windows vents;
❍theheatedrearwindscreenisturnedon
❍shows fan speed (LED G lit).
IMPORTANT The MAX-DEF function will remain on for approximately
3 minutes from when the engine coolant reaches adequate tem-
perature.
The LED on the AUTO button will go out when the function is on.
With the function activated the only possible manual adjustments
are adjusting the fan speed and the turning the heated rear wind-
screen off. By pressing B, C,
-or AUTO buttons, the climate
control system will turn the MAX-DEF off.

DEMISTING/DEFROSTING
HEATED REAR WINDSCREEN
Press(to turn heated rear windscreen demisting/defrosting func-
tion on (LED on button lit). This function switches off automatically
after about 20 minutes or when the engine is turned off. It is not
switched on automatically the next time the engine is started. For
versions/markets, where provided, pressing the
(button it is al-
so possible to defrost/demist the external rearview mirrors, the heat-
ed windscreen (for versions/markets, where provided) and the heat-
ed spray nozzles (for versions/markets, where provided).
IMPORTANT Do not affix stickers to the inside of the heated rear
windscreen on the heating filaments, to avoid damage that might
cause them to stop working properly.
Humidity sensor(for versions/markets, where provided)
The humidity sensor prevents the windows from misting up. For
full operation, it is advisable to turn the AUTO on (LED N on). When
the outside temperature is low, the system could automatically turn
the compressor on and turn air recirculation off for safer driving.
TURNING THE CLIMATE CONTROL SYSTEM OFF
Pressgbutton (LED on button off):
❍air recirculation is on, thus isolating the passenger compartment
from the outside;
❍the compressor is off;
❍the fan is off.
❍the heated rear windscreen can be switched on or off.
❍the AQS (Air Quality System) function cannot be turned on.
IMPORTANT The climate control system control unit stores the tem-
peratures set before the system was switched off and restores
the same conditions when any button of the system is pressed (ex-
cept for D button).
Press AUTO button to restart the climate control system in fully
automatic mode.

NOTAWhen the Start&Stop function is active (engine off and
vehicle speed zero), the automatic recirculation management is
turned off always taking air in from outside, to reduce the proba-
bility of window misting up (as the compressor is off).
SUPPLEMENTARY ELECTRIC HEATER
(for versions/markets where provided)
This device speeds up passenger compartment warming when it is
very cold. The additional heater turns off automatically after reach-
ing the required comfort conditions.
Automatic dual zone climate control system
(for versions/markets, where provided)
The supplementary electric heater is operated automatically ac-
cording to environmental conditions and when the engine is run-
ning.
Manual climate control system
The supplementary heater is activated automatically by turning A
knob to the end of the red section and setting the fan (knob B)
to at least the 1
stspeed.
IMPORTANT NOTES
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.
START&STOP
Automatic climate control system
The automatic climate control system manages the Start&Stop
function (engine off when speed is zero) to ensure adequate com-
fort inside the passenger compartment.
Specifically, the Start&Stop function is turned off when the weath-
er is particularly hot or cold to guarantee an adequate level of com-
fort 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 is on and the engine is off at zero speed,
the climate control system will turn the engine back on if the in-
side temperature conditions should rapidly deteriorate (or if the
user asks for maximum cooling – LO – or quick demisting –
MAX-DEF).
With the Start&Stop function on and engine off at zero speed,
air flow is reduced to the minimum to main comfort conditions in-
side the passenger compartment as long as possible when the sys-
tem is in AUTO mod (LED N on).
The climate control system 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 priv-
ileged by turning the Start&Stop off by pressing the button on
the dashboard.
NOTAIn particularly severe climate conditions it is recommended
to limit the use of the Start&Stop function to prevent the com-
pressor from continuously switching on and off, with following fa-
st window misting and accumulation of humidity with unpleasant
smells in the passenger compartment.

EXTERIOR COURTESY LIGHTS
This function lights up the vehicle and the space around it when
the doors are unlocked.
Activation
When the car is parked and the doors are unlocked by pressing the
Ëbutton on the remote control (or the boot is unlocked by press-
ing
R), the dipped beam headlights, side lights and number
plate lights are activated.
The lights remain lit for approximately 25 seconds unless the doors
and boot are locked once again, the doors or boot are opened
and closed or the instrument panel is activated. In these cases they
go out after 5 seconds.
The exterior courtesy lights can be enabled/disabled using the Set-
up Menu (see the paragraph “Menu Items” in this chapter).
“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 ignition key on STOP or removed, pull A stalk fig. 40 to-
wards the steering wheel within 2 minutes of the engine switch-
ing 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.
The
3warning light on the instrument panel will light up (and
the corresponding message will appear on the display) as long as
the function is active.
The light comes on when the stalk is first moved and stays on un-
til the function is automatically deactivated. Each movement of the
stalk increases only the amount of time the lights stay on.
Deactivation
Keep the A stalk fig. 40 pulled towards the steering wheel for more
than 2 seconds.

Move the stalk up (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 automati-
cally stopped.WINDOW CLEANING
The right stalk controls windscreen wiper/washer and heated rear
windscreen wiper/washer operation.
WINDSCREEN WIPER/WASHER fig. 41
This only operates with the ignition turned to MAR. A Ring can take
three different positions:
Owindscreen wiper off;
≤intermittent operation (low speed);
AUTO rain sensor activation (for versions/markets, where pro-
vided) (the windscreen wiper speed is automatically adapt-
ed to the intensity of the rain)
nintermittent operation;
≥slow operation;
¥fast operation.
fig. 41A0K0097m
Do not use the windscreen wipers to remove lay-
ers of snow or ice from the windscreen. In such con-
ditions, the windscreen wipers may be subjected to
excessive stress, prompting intervention from the motor
protection which prevents operation for a few seconds. If
operation is not restored, even after turning the key and
restarting the engine, contact Alfa Romeo Authorized Ser-
vices.
Do not operate the windscreen wiper with the
blades lifted from the windscreen.
“Smart washing” function
Pull the stalk towards the steering wheel (unstable position) to op-
erate the windscreen washer jet. Keep the stalk pulled for more
than half a second, with just one movement, to operate windscreen
washer/wiper jet at the same time.
The wiper stops working three strokes after the stalk is released.
A further stroke after approximately six seconds completes the wip-
ing cycle.

If the engine is switched off with the stalk in the automatic posi-
tion, no wiping cycle will take place when the engine is started
again even if it is raining. This prevents accidental activation of the
rain sensor when the engine is started (i.e. when the windscreen
is being washed by hand or the wipers are stuck to the windscreen
by ice).
To restore automatic operation of the rain sensor, turn the ring on
the right A stalk fig. 41 from automatic position (AUTO) to
Opo-
sition and then turn A ring 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 wind-
screen. If the sensitivity of the rain sensor is adjusted whilst it is
in operation, a single stroke of the windscreen wiper takes place
to confirm the changed setting.
In the event of the malfunction of the rain sensor whilst it is ac-
tive, the windscreen wiper operates intermittently at a speed con-
sistent with the sensitivity setting of the rain sensor, regardless of
whether it is raining or not (the sensor fault is indicated on the
instrument panel display). The sensor continues to operate and it
is possible to set the windscreen wiper to continuous mode (1
st
or 2ndspeed). The fault indication remains for as long as the sen-
sorisactive.
RAIN SENSOR fig. 42
(for versions/markets, where provided)
This is an infrared LED sensor fitted on the windscreen. It can de-
tect the presence of rain and consequently manage windscreen wip-
ing in accordance with the amount of water on the windscreen.
Activation
The sensor is activated by turning the A ring fig. 41 to the
“automatic” position (“AUTO”): the frequency of the windscreen
wiper strokes is automatically adjusted depending on 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).
Turn the A ring fig. 41 to vary the rain sensor sensitivity.

INCREASING THE STORED SPEED
Press the accelerator and store the new speed or move the stalk
upwards (+). Each movement of the stalk will correspond to an
increase in speed of about 1 km/h, while keeping the stalk held
upwards the speed will continuously increase.
REDUCING THE STORED SPEED
Deactivate the device and store the new speed or move the stalk
downwards (–) until the new speed is reached. It will then auto-
matically be stored. Each movement of the stalk will correspond
to a reduction in speed of about 1 km/h, while keeping the stalk
held downwards will continuously reduce the speed.
TURNING THE DEVICE OFF
Toturnthedeviceoff:
❍turn the A ring fig. 43 to OFF;
❍stop the engine;
❍press the brake pedal, the clutch or the accelerator; in this
last case the system is not actually turned off but the system
gives priority to the acceleration request. The device still re-
mains active, without the need to press the RES button to re-
turn to the previous condition once acceleration is concluded. When travelling downhill with the device engaged, the car may
slightly exceed the preset speed. When the device is activated,
Ü
light comes on together with the relevant message on the instru-
ment panel (for versions/markets, where provided).
STORING THE SPEED
Proceed as follows:
❍turn A ring fig. 43 to ON and press the accelerator until the
car reaches the desired speed;
❍move the stalk upwards (+) for at least one second, then re-
lease it. The speed is now stored and you can therefore release
the accelerator pedal.
If needed (when overtaking for instance), you can accelerate sim-
ply by pressing the accelerator pedal; when you come off the ped-
al, the car will return to the speed memorised previously.
RESTORING STORED SPEED
If the device was disengaged - for example by pressing the brake
or clutch pedal - the stored speed can be reset as follows:
❍accelerate gradually until reaching a speed approaching the one
stored;
❍engage the gear selected at the time of speed storing;
❍press RES button (B-fig. 43).
