Alfa Romeo Giulietta 2016 Owner's Guide

Position A: Air flow distribution
between centre/side dashboard
vents, rear diffuser and windscreen
and front side window demisting/
defrosting diffusers. This
distribution setting ventilates the
passenger compartment well and
prevents the windows from misting
up.
Position B: Air flow distributed
between footwell diffusers and
windscreen and front side window
defrosting/demisting diffusers.
This distribution setting allows the
passenger compartment to warm
up efficiently and prevents the
windows from misting up.
Position C: Air flow distribution
between footwell diffusers (hotter
air) and centre/side dashboard
diffusers and rear diffuser (cooler
air).
Position D: Automatic
demisting/defrosting activation
(see description in previous
pages).START&STOP
Manual climate control
If the Start&Stop function is activated
(engine off when the car speed is
0 km/h), the system keeps the air flow
selected by the user.
In these conditions, the compartment
cooling and heating cannot be
guaranteed, as the compressor stops
with the engine coolant pump.
The Start&Stop function can be
deactivated to enhance the operation of
the climate control system by pressing
the dedicated button on the
dashboard.
SERVICING
MAINTENANCE
In winter, the climate control system
must be turned on at least once a

DESCRIPTION
The automatic dual zone climate control
system regulates the air temperatures
in the passenger compartment in two
areas: driver side and passenger side.
The system maintains comfort inside
the passenger compartment and
compensates for possible variations in
external climate conditions.
NoteThe reference temperature is
22°C for optimal comfort management.
The automatically controlled
parameters and functions are:
❒air temperature at the driver's/front
passenger side vents;
❒air distribution at the driver's/front
passenger side vents;❒fan speed (continuous variation of the
air flow);
❒compressor engagement (for
cooling/dehumidifying the air);
❒air recirculation.
All these functions can be adjusted
manually by operating the system and
selecting one or more functions and
modifying their parameters. Automatic
control of the manually changed
functions will be suspended: the
system will only override the settings for
safety reasons.
Manual selections always have higher
priority than automatic settings and are
stored until the AUTO button is
pressed, except for cases in which the
system intervenes for safety reasons.
You can adjust one function manually
without affecting the automatic control
of the others. The amount of air
introduced into the passenger
compartment is not affected by vehicle
speed; it is electronically controlled
by a fan.
The temperature of the air sent is
always automatically controlled
according to the temperature set on the
display (except for when the system is
off or in certain conditions when the
compressor is not running).
2)
The system allows the following to be
set or adjusted manually:
❒driver's/passenger side air
temperature;
❒fan speed (continuous variation);
❒air distribution pattern with 7
positions;
❒compressor enabling;
❒rapid defrosting/demisting function;
❒air recirculation;
❒heated rear window;
❒system deactivation.
CLIMATE CONTROL
SYSTEM OPERATING
MODES
The climate control system can be
activated in different ways: it is
advisable to press the AUTO button
and turn the knobs to set the desired
temperatures.
In this way the system operates
completely automatically to adjust the
temperature, quantity and distribution
of the air introduced into the passenger
compartment. It also manages the air
recirculation system and the activation
of the air conditioning compressor.
29

During automatic operation, you can
change the set temperatures, air
distribution and fan speed at any time
by using the relevant buttons or knobs:
the system will automatically change
the settings to adjust to the new
requirements.
During fully automatic operation
(AUTO), the word AUTO will disappear
if the air distribution and/or flow rate
and/or engagement of the compressor
and/or recirculation settings are
changed.
During fully automatic operation (FULL
AUTO), the word FULL will disappear
if the air distribution and/or flow rate
and/or activation of the compressor
and/or recirculation settings are
changed.
In this way the climate control system
will continue to automatically manage
all functions except for those that have
been manually adjusted. The fan speed
is the same in all the zones of the
passenger compartment.ADJUSTING THE AIR
TEMPERATURE
Turn knob A or L to the right or left to
adjust the air temperature: knob A
for the front left area, knob L for the
front right area of the passenger
compartment. The set temperatures are
shown on the displays.
Press the MONO button to align the air
temperature between the two areas.
Turn knob L to return to the separate
management of air temperatures in the
two areas.
Turn the knobs fully right or left to
engage HI (maximum heating) or LO
(maximum cooling) respectively. To
deactivate these functions, turn the
temperature knob to the desired
temperature.
SETTING THE AIR
DISTRIBUTION
By pressing the buttons (
//), it
is possible to set one of the 7 possible
air distributions manually:
Air flow to the windscreen and
front side window diffusers to
demist/defrost them.
Air flow at central and side
dashboard vents to ventilate the
chest and the face during the hot
season.
Air flow to the front and rear
footwell diffusers. This air
distribution setting heats the
passenger compartment most
quickly, giving a prompt sensation
of warmth.
Air flow distributed between
footwell vents (hotter air) and
central and side dashboard
vents (cooler air). This
distribution setting is useful in
spring and autumn on sunny
days.
Air flow distributed between
footwell diffusers and
windscreen and front side
window defrosting/demisting
diffusers. This distribution
setting allows the passenger
compartment to warm up
efficiently and prevents the
windows from misting up.
Air flow distribution between
windscreen demisting/
defrosting diffusers and side
and central dashboard vents.
This allows air to be sent to
the windscreen in conditions of
strong sunlight.
Air flow distribution to all
vents on the car.
30
GETTING TO KNOW YOUR CAR

In AUTO mode, the climate control
system automatically manages air
distribution (the LEDs on buttons H are
off). When set manually, the air
distribution is shown by the LEDs on
the selected buttons.
In combined function mode the relevant
function is enabled simultaneously
with those already set by pressing the
corresponding button. If a button
whose function is already active is
pressed, its operation is cancelled and
the corresponding LED switches off.
To restore automatic control of the
air distribution after a manual selection,
press the AUTO button.
ADJUSTING THE FAN
SPEED
Turn knob F to increase/decrease the
fan speed. The speed is indicated
by the LEDs G on knob F switching on.
❒maximum fan speed = all LEDs lit;
❒minimum fan speed = one LED lit.
The fan can only be excluded if the
climate control compressor has been
switched off by pressing button C.
IMPORTANT To restore automatic
control of the fan speed after a manual
adjustment, press the AUTO button.AUTO BUTTON
By pressing the AUTO button (LED on
button lit) the climate control system
automatically adjusts the following
settings in the corresponding zones:
❒quantity and distribution of the air
introduced into the passenger
compartment;
❒climate control compressor;
❒air recirculation
❒cancelling any previous manual
settings.
This is indicated by the LED on the
AUTO button switching on.
By manually adjusting at least one of
the functions automatically managed by
the system (air recirculation, air
distribution, fan speed or switching off
the air conditioner compressor), the
LED will switch off, indicating that the
climate control system is no longer
automatically controlling all the
functions.
IMPORTANT Should the system no
longer be able to guarantee the
required temperature set in various
passenger compartment zones, the set
temperature value will flash for a few
seconds.To restore automatic system control
after one or more manual adjustments,
press the AUTO button.
MONO BUTTON
Press the MONO button (LED on
button lit) to align the passenger side air
temperature with that of the driver
side.
This function makes temperature
regulation easier when the driver is
travelling alone.
Turn knob L to set the passenger side
temperature and return to separate
air temperature management.
AIR RECIRCULATION AND
ENABLEMENT OF AQS
FUNCTION (Air Quality
System)
(for versions/markets, where provided)
The air recirculation is managed
according to the following operating
logics:
❒automatic activation: text A on button
B lit;
❒forced activation (inside air
recirculation always on): indicated by
the LED on button
and text A
off;
31

❒forced deactivation (air recirculation
always off, air drawn in from the
outside): indicated by the LED on
buttons
switching off and text A
on button B off.
Forced activation/deactivation can be
selected by pressing button
.
When the
button is pressed (button
E off), the climate control system
automatically activates internal air
recirculation (LED on
button A
on). It is still possible to activate outside
air recirculation (LED on the button off)
and vice versa, by pressing button
.
The AQS (Air Quality System) function
(for versions/markets, where provided)
cannot be activated when the
button
is pressed (LED on button E off).
AQS (Air Quality System)
function activation
(for versions/markets, where provided)
The AQS function automatically
activates internal air recirculation when
the outside air is polluted (e.g. in traffic
queues and tunnels).IMPORTANT With the AQS function
active, after a preset time interval of the
internal air recirculation system
functioning, the climate control system
enables the intake of outside air for
approximately one minute to change
the air in the passenger compartment.
This takes place regardless of the
pollution level of the outside air.
IMPORTANT The engagement of the
recirculation system makes it possible
to reach the required heating/cooling
conditions faster. It is, however,
inadvisable to use it on rainy/cold days
as it would considerably increase the
possibility of the windows misting
up inside (especially if the climate
control system is off). When the outside
temperature is low, recirculation is
forced off (air drawn in from the outside)
to prevent the windows from misting
up.
In automatic operation, recirculation is
managed automatically by the system
according to outside environmental
conditions.
IMPORTANT It is advisable not to use
the air recirculation function when
the outside temperature is low to
prevent the windows from rapidly
misting up.CLIMATE CONTROL
COMPRESSOR
Press button C to activate/deactivate
the compressor (activation is indicated
by the lit LED on the button). 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 recirculation
to prevent the windows from misting
up and deactivates the AQS function
(for versions/markets, where provided).
In this case, although the climate
control system is capable of
maintaining the required temperature,
the AUTO LED switches off. The
temperatures will flash for a few
seconds if the required temperature
cannot be maintained.
To restore automatic control of
compressor engagement, press again
button C or the AUTO button.
With compressor off:
❒if the outside temperature is higher
than the set one, the system will
not be able to satisfy the request.
The temperature values will then flash
on the display for a few seconds to
indicate this;
❒the fan speed can be reset manually.
32
GETTING TO KNOW YOUR CAR

With the compressor on and the engine
running, manual ventilation cannot be
lower than the minimum speed (only
one LED lit).
IMPORTANT With the compressor off,
air cannot be introduced to the
passenger compartment with
a temperature lower than the outside
temperature. Moreover, under certain
environmental conditions, windows
could mist up rapidly since the air is not
dehumidified.
RAPID WINDOW
DEMISTING/DEFROSTING
(MAX-DEF function)
Press the
button to activate (LED
on button on) the windscreen and side
windows demisting/defrosting function.
The climate control system carries out
the following operations:
❒switches on the air conditioning
compressor when climatic conditions
are suitable;
❒deactivates air recirculation;
❒sets maximum air temperature (HI) in
both zones;
❒sets fan speed according to the
engine coolant temperature;
❒directs air flow to windscreen and
front side windows diffusers;❒activates the heated rear window.
❒displays the fan speed (LED G lit).
IMPORTANT The MAX-DEF function
remains on for about 3 minutes from
when the engine coolant reaches the
appropriate temperature.
When the function is activated, the LED
on the AUTO button switches off.
With the function activated the only
possible manual adjustments are
adjusting the fan speed and turning the
heated rear window off.
When the B, C,
or AUTO buttons
are pressed, the climate control system
will turn the MAX-DEF off.
HEATED REAR WINDOW
DEMISTING/DEFROSTING
Press the
button to activate (LED
on button on) heated rear window
demisting/defrosting.
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,
press the
button to activate
demisting/defrosting of exterior rear
view mirrors and heated nozzles (for
versions/markets, where provided).IMPORTANT Do not affix stickers to the
inside of the heated rear window over
the heating filaments, to avoid damage
that might cause them to stop working
properly.
Thermal comfort
windscreen
(for versions/markets, where provided)
Some versions feature a thermal
comfort windscreen which, with the car
exposed to the sun, reduces the
temperature in the passenger
compartment relative to the outside
temperature, thus ensuring greater
comfort.
Humidity sensor
(for versions/markets, where provided)
The humidity sensor helps to prevent
the windows from misting up. For
full functionality, it is advisable to
activate the AUTO function (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.

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

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
.

AUTOMATIC LIGHTING
CONTROL (AUTOLIGHT)
(Dusk sensor)
(for versions/markets, where provided)
This infrared LED sensor, combined
with the rain sensor and located on the
windscreen, detects the variations in
outside brightness depending on the
light sensitivity set with the Setup
Menu: the greater the sensitivity, the
less external light is required to activate
the external lights.
Activation
The dusk sensor activates when ring
nut A fig. 31 is turned to
. In this
way the side lights and dipped beam
headlights are activated automatically
according to the external lighting
conditions.
IMPORTANT The sensor is unable to
detect the presence of fog. Therefore
under these circumstances, these lights
must be turned on manually.When the lights are turned on by the
sensor, the fog lights (for versions/
markets, where provided) and the rear
fog lights may be turned on.
When the lights are automatically
switched off, the front and rear fog
lights (if activated) are also switched off.
The next time the lights are switched
on automatically, the fog lights must be
reactivated manually (if required).
With the sensor active, it is possible to
flash the headlights but the main beam
headlights cannot be switched on. To
activate these lights, turn the ring nut A
to
and activate the fixed dipped
beam headlights.
When the lights have been activated
automatically and are then switched off
by the sensor, the dipped beam
