Window demisting
The climate control system is very useful in preventing the windows
from misting up in the event of high levels of humidity.
In the event of considerable outside moisture and/or rain and/or
considerable differences in temperature inside and outside the pas-
senger compartment, proceed as follows to demist the windows:
❍turn A knob to the red section;
❍press F button to disable the air recirculation system (the LED

DEMISTING/DEFROSTING
HEATED REAR WINDSCREEN
Press D button (() to turn the function on/off. The function is au-
tomatically deactivated after 20 minutes.
For versions/markets, where provided, pressing the
(button
also defrost/demist the external rearview mirrors and the heated
spray nozzles (for versions/markets, where provided).
IMPORTANT Do not affix stickers to the inside of the heated rear
windscreen over the heating filaments, to avoid damage that might
cause them to stop working properly.
AIR RECIRCULATION
Press F (v) button so that the LED on the button lights up. It
is advisable to switch air recirculation on while standing in traffic
or in tunnels to prevent the introduction of polluted air.
Do not use the function for a long time, particularly if there are many
passengers on board, to prevent the windows from misting up.
IMPORTANT The air recirculation system makes it possible to reach
the required heating or cooling conditions faster. Do not use the air
recirculation function on rainy/cold days as it would considerably
increase the possibility of the windows misting.
AIR DISTRIBUTION SELECTION
Turn E knob fig. 38 to manually select one of the four possible
air distribution settings in the passenger compartment:
xAir flow to the windscreen and front side window vents to
demist/defrost them.
sAir flow to the front and rear footwell vents. This air distrib-
ution allows the passenger compartment to be warmed up
quickly.
yAir flow distribution between front and rear vents, centre/side
dashboard vents, rear vent and windscreen and front side win-
dow demisting/defrosting vents.
rAir flow distribution to centre/side dashboard vents (pas-
senger’s body).

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.
A0K0083m
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).
