Switching Off/On The Climate Control System - Alfa Romeo GIULIETTA Owner's Handbook Manual

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).

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.
Note In 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.
Note When 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).
