Hot engine coolant (red)
When the ignition key is turned to MAR, the warning
light turns on but should go off after a few seconds.
The warning light turns on when the engine is over-
heated. A specific message will be shown on the display.
If the warning light comes on, proceed as follows:
❍when driving normally: stop the car, switch off the engine and
check that the water level in the reservoir is not below the MIN
mark. If it is not, wait for a few minutes for the engine to cool
down then slowly and carefully open the cap, top-up with coolant
and check that the level is between the MIN and MAX marks.
Also visually check for leaks. If the warning light comes on again
at the next engine start-up, contact Alfa Romeo Authorized Ser-
vices.
❍if the car is used under demanding conditions (e.g. towing trail-
ers uphill or fully loaded): slow down and, if the light stays on,
stop the car. Stop for two or three minutes with the engine run-
ning and slightly accelerated to assist better coolant circulation.
Then switch the engine off. Check correct fluid level as described
above.
IMPORTANT On particularly demanding journeys, it is advisable to
keep the engine on and slightly accelerated for a few minutes be-
fore switching it off.
u
Door open (red)
(for versions/markets, where provided)
The warning light (or symbol on the display) comes
on when one or more doors or the boot are not perfectly
closed. An acoustic signal is activated with the doors open and
the car moving. On some versions, the warning light (or symbol
on the display) also lights up when the bonnet is not perfectly
closed.´
EOBD/injection system fault (amber)
Under normal conditions, the warning light comes on
when the ignition key is turned to MAR, but should
go off as soon as the engine is started.
If the warning light remains on or comes on whilst driving, that
means that the injection system is not working properly; in partic-
ular, if the warning light comes on constantly, this indicates a mal-
function in the supply/ignition system that could cause excessive
exhaust emissions, a possible loss of performance, poor driveabil-
ity and high fuel consumption.
A specific message is displayed on certain versions.
Under these conditions, you can continue travelling at moderate
speed without demanding excessive effort from the engine. Pro-
longed use of the car with the warning light on may cause dam-
age. Contact Alfa Romeo Authorized Services as soon as possible.
The warning light goes out after the fault disappears, but the in-
dication is stored in the system.U

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).

You can adjust one function automatically and have the automat-
ic system control all 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 au-
tomatically controlled according to the temperature shown on the
display (except for when the system is off or in certain conditions
when the compressor is not running).
The system can manually programme and adjuste:
❍air temperature on driver’s/passenger’s side;
❍fan speed (continuous variation);
❍air distribution to 7 positions;
❍climate control compressor enabled;
❍fast demisting/defrosting function;
❍air recirculation;
❍heated rear windscreen;
❍turning the system off.
DESCRIPTION
The automatic dual zone climate control system regulates the tem-
perature in the passenger compartment in two areas. The system
keeps the comfort in the passenger compartment constant and
compensates for variable external conditions.
NOTEThe reference temperature is 22°C for optimal comfort man-
agement.
The automatically controlled parameters and functions are:
❍air temperature delivered to driver/front passenger vents;
❍air distribution to driver/front passenger vents;
❍fan speed (continuous air flow variation);
❍switching the compressor fan on (for cooling/dehumidifying
the air);
❍air recirculation.
All these functions can be manually adjusted by operating the sys-
tem and selecting one or more functions and modifying their pa-
rameters. Automatic control of the manually changed functions will
be suspended: the system will only override your settings for safe-
ty reasons.
Manual selections will always have higher priority over automatic
settings and will be stored until the AUTO button is pressed, except
for the cases in which the system will intervene for particular, safe-
ty-related reasons.
The climate control system uses an average radi-
ating temperature sensor installed under a cover
below the inner rearview mirror. To ensure opti-
mal operation of the climate control system, do not ob-
struct the detection cone of this sensor with any object.

ADJUSTING THE AIR TEMPERATURE
Turn A or L knob to 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 display.
Press the MONO button to align the air temperature between the
two zones.
Turn L knob to go back to the separate management of air tem-
peratures in the two zones.
Turn the knobs fully clockwise or anti-clockwise to engage respec-
tively HI (maximum heating) or LO (maximum cooling). To de-
activate these functions, rotate the temperature knob to the de-
sired temperature.
SWITCHING THE CLIMATE CONTROL SYSTEM ON
The system can be turned on in different ways: you are recom-
mended to press the AUTO button and turn the knobs to set the re-
quired temperatures.
In this way the system operates completely automatically to ad-
just the temperature, quantity and distribution of the air introduced
into the passenger compartment. It also manages the air recircu-
lation system and the enablement of the air conditioning com-
pressor.
During fully automatic system operation, you can change at any
time the set temperatures, air distribution and fan speed by using
the relevant buttons or knobs: the system will automatically change
its settings to adjust to the new requirements.
During fully automatic operation (AUTO), the word AUTO will dis-
appear if the air distribution and/or flow rate and/or engagement
of the compressor and/or recirculation settings are changed.
In this way the climate control system will continue to automati-
cally manage all functions except for those that have been manu-
ally adjusted. There is only one fan speed in all the areas of the
passenger compartment.
