2013 Alfa Romeo Giulietta maintenance

DESCRIPTIONThe 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 air temperature 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).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.
The climate control system detects the passenger
compartment temperature through a mean radiant
temperature sensor installed in a cover under the rear view
mirror; if the cone of this sensor is obstructed by any object, the system
may not work correctly.
SWITCHING ON THE CLIMATE
CONTROL SYSTEMThe climate control system can be switched on in different ways: we
recommend pressing the AUTO button and turning 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.

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 TEMPERATURETurn the A or L knob right or left to adjust the air temperature: A knob
for the front left-hand area, L knob for the front right-hand 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 the L knob to return to the separate management of air
temperatures in the two zones.
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 DISTRIBUTIONBy 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.
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.

❒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 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 control of the system after one or more manual
adjustments, press the AUTO button.
MONO BUTTONPress the MONO button (LED on button lit) to align the passenger side
air temperature with that of the driver side.

AIR RECIRCULATION AND
ENABLEMENT OF AQS FUNCTION
(Air Quality System)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 the button
A and text A off;
❒forced deactivation (air recirculation always off, air drawn in from
the outside): indicated by the LED on the
buttons A switching
off and text A on button B off.
Forced activation/deactivation can be selected by pressing the
button A.
When the
button is pressed (button E off), the climate control system
automatically activates internal air recirculation (LED on the
button A on). It is still possible to activate outside air
recirculation (LED on the button off) and vice versa, by pressing the
button
A.
The AQS (Air Quality System) function cannot be activated when the
button is pressed (LED on button E off).
AQS (Air Quality System) function activation
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.
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 COMPRESSORPress 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. In this case, although the system is capable of
maintaining the required temperature, the AUTO LED switches off.
The temperatures will instead flash for a few seconds if the required
temperature cannot be maintained.
To restore automatic control of compressor engagement, press button C
again or press the AUTO button.

❒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.
With the compressor on and the engine running, manual ventilation
cannot be lower than the minimum speed (only one LED lit).
IMPORTANT With the climate control 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 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 window 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/DEFROSTINGPress 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).

With compressor off:

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 OFFPress 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 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).
To restart the climate control system in fully automatic mode press the
AUTO button.
START&STOPAutomatic Climate Control
The automatic climate control system manages the Start&Stop function
(engine off when speed is zero) to ensure adequate 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 the reactivation 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.

this way the side lights and dipped headlights are activated
automatically according to the external light level.
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. If you need to turn these
lights on, turn ring nut A to position
