AIR TEMPERATURE
ADJUSTMENT KNOBS
Turning the knob knurled rings (B/
E/P), clockwise or counter-clockwise,
respectively raises or lowers the tem-
perature of the air required respective-
ly in the left front zone (knob B) or right
front zone (knob E) or rear zone (knob
P) of the passenger compartment. The
temperatures set are shown on the dis-
playD/S.
Turning the knob knurled rings fully
clockwise or counter-clockwise until they
reach the extreme selections HIorLO,
the maximum heating or cooling func-
tions are respectively engaged.HI function (HIGH)
(maximum heating power)
It is switched on by setting a tempera-
ture of more than 32°C on the display,
and can be switched on independently
from the driver’s or passengers’ side, or
both of them; this setting brings the sys-
tem to the “one-zone” mode and it is
shown by both displays.
This functions can be switched on when
you wish to heat the passenger com-
partment as quickly as possible, by tak-
ing the greatest advantage from the sys-
tem potential.
The function uses the maximum tem-
perature of the heating fluid, whereas
air distribution and fan speed are con-
trolled automatically by the system.
SWITCHING THE CLIMATE
CONTROL SYSTEM ON
The system can be turned on by press-
ing any button (excluding
(,vand
MONO); it is however advisable to set
the required temperatures on the display
and then to press the AUTO button.
The climate control system allows to per-
sonalise required temperatures (driver and
passengers).

AIR RECIRCULATION AND
AQS FUNCTION (AIR
QUALITY SYSTEM)
ON/OFF (where provided)
Inside air recirculation is controlled ac-
cording to the following operating log-
ics:
❒automatic control, indicated by but-
ton led “A”;
❒forced switching on (inside air recir-
culation always on), indicated by the
turning on of the circular led around
the button;
❒forced switching off (air recirculation
always off with air inlet from the out-
side), indicated by the turning off of
the circular led around the button.
With A.Q.S. (air quality sensor - where
provided), the operating logics becomes
sequential by pressing button
v.IMPORTANTThe inside air recircula-
tion system makes it possible to reach
the required heating or cooling condi-
tions faster. It is however inadvisable to
use it on rainy/cold days as it would
considerably increase the possibility of
the windows misting inside, especially
if the climate control compressor is off.
It is advisable to turn on the inside air
recirculation system in queues or tunnels
to avoid admitting polluted air from out-
side. The prolonged use of this function
should however be avoided, especially
with several persons on board, to avoid
the possibility of the windows misting
inside and to guarantee the required
fresh air inlet.

❒pressing the brake pedal, pressing the
clutch pedal (in these cases the last
stored speed will stay memorised, to
resume it press button RES);
❒pressing the accelerator pedal; in this
case the system is disengaged only
temporarily; device operation will be
resumed automatically when releas-
ing the pedal;
❒with car speed below the preset lim-
it (in these cases the last stored
speed will stay memorised, to resume
it press button RES);
Automatic Cruise Control
deactivation
The Cruise Control is temporarily deac-
tivated when the ABS or VDC systems
come into operation (above a max. pre-
set time): in this case the last set speed
will stay memorised, to recall it press
buttonRES.
In the event of Cruise Control or engine
control system failure, the device is de-
activated until removing the electronic
key from the ignition device. In this
event contact Alfa Romeo Authorized
Services.
❒engage the gear selected at the time
of speed memorising (4th or 5th
gear);
❒press the RESbutton (set at stalk
end).
TO INCREASE THE
MEMORISED SPEED
The speed memorised can be increased
in two ways:
❒pressing the accelerator and then
memorising the new speed reached;
or
❒moving the stalk upwards (+).
Each operation of the stalk will corre-
spond to a slight increase in speed
(about 1.5 km/h), while keeping the
stalk upwards will correspond to a con-
tinuous speed increase.
TO REDUCE MEMORISED
SPEED
The speed memorised can be increased
in two ways:
❒disengaging the device and then
memorising the new speed;
or
❒moving the stalk downwards (–) un-
til reaching the new speed which will
be memorised automatically.
Each operation of the stalk will corre-
spond to a slight decrease in speed
(about 1.5 km/h), while keeping the
stalk downwards will correspond to a
continuous speed decrease.
DEVICE DISENGAGEMENT
The device is disengaged in one of the
following cases:
❒turning the knurled ring A-fig. 57
toO;
❒turning the engine off or removing
the electronic key from the ignition

Improper use of the
power windows can be
dangerous. Before and
during its operation ensure that
any passengers are not at risk
from the moving glass either by
personal objects getting caught
in the mechanism or by being in-
jured by it directly. Always re-
move the ignition key when
getting out of the car to prevent
the power windows being op-
erated accidentally and consti-
tuting a danger to the passen-
gers in the car.

Performance of the
VDC system, in terms
of active safety should not in-
duce the driver to take point-
less and unnecessary risks.
The style of driving must in
any case always be adapted to
the conditions of the road sur-
face, visibility an traffic. Road
safety is always the driver’s
responsibility.
WARNING
During the use of the
space-saver spare
wheel (where provided), the
VDC system carries on work-
ing. However, you must re-
mind that the space-saver
spare wheel has dimensions
smaller than the standard tyre
and therefore its grip is re-
duced as to the other car tyres.
WARNING
For correct operation of
the VDC system, the
tyres must absolutely be of
the same brand and type on all
wheels, in perfect conditions
and, above all, of type, brand
and size specified.
WARNING
HILL HOLDER SYSTEM
(where provided)
This system is an integral part of the VDC
system and it is provided to facilitate
starting on slopes:
❒uphill: car at a standstill on a road
with a gradient higher than 6%, en-
gine running, clutch and brake ped-
al depressed, gearbox to neutral or
engaged gear other than reverse;
❒downhill: car at a standstill on a road
with a gradient higher than 6%, en-
gine running, clutch and brake ped-
al depressed and reverse gear en-
gaged.
At pickup the VDC system control unit
will keep brake force on wheels until
reaching the torque suitable for starting,
or in any case for about 1 second in or-
der to pass easily from the brake pedal
to the accelerator pedal.

The acoustic alarm will stop immediately
as distance raises. The acoustic alarm is
constant if the distance measured by
central sensors is unvaried, whereas if
this situation takes place for side sen-
sors the acoustic alarm is muted after
about 3 seconds to prevent sound indi-
cations when performing manoeuvres
near walls.
SENSORS
Obstacles are detected by 4 sensors lo-
cated in the front bumper (where pro-
vided)fig. 105and 4 sensors located
in the rear bumperfig. 106.
Parking manoeuvres
however are always
under the driver’s responsibil-
ity that shall always check the
absence of people (specially
children) or animals in the ma-
noeuvre space. This system is
just a help for the driver but
she/he shall never reduce at-
tention during dangerous ma-
noeuvres even if performed at
low speed.

BUZZER
The presence of any obstacle and its dis-
tance from the car is indicated by the
buzzers installed inside the passenger
compartment:
❒on versions with 4 rear sensors, the
rear buzzer will indicate the presence
of rear obstacles;
❒on versions with 8 sensors (4 front
sensors and 4 rear sensors) obstacles
are indicated by rear and front
buzzers. This feature gives the dri-
ver the direction (front/rear) of the
obstacle.
