ed) (or as an alternative, on certain ver-
sions, a symbol and a message are dis-
played). In this event contact Alfa
Romeo Authorized Services.
IMPORTANTIf after trying to turn on
the instrument panel and/or to start the
engine, the instrument panel warning
light
>(where provided) (or as an al-
ternative, on certain versions the mes-
sage "Vehicle protection system not
available" is displayed), repeat the op-
eration moving the steering wheel in or-
der to release the steering lock. The dis-
played warning message will not impair
steering lock operation.
INSTRUMENTS
REV. COUNTER
Rev counter shows engine rpm. The red
zone at the scale bottom indicates that
the engine is running at excessive rpm
dangerous for mechanical components.
Do not drive with the pointer in this area.
IMPORTANTThe electronic injection
control system gradually shuts off the
flow of fuel when the engine is “over-
revving” (rev counter pointer in the red
area) resulting in a gradual loss of en-
gine power, in order to bring engine rpm
below to the safety limit.
The rev counter may, when the engine
is idling, indicate gradual or sudden in-
crease of engine revs as the case may
be; such behaviour is normal and must
not be interpreted as a faulty condition
as it occurs during normal operation, for
instance when climate control or electric
fan are switched on. In particular, slow
revs variation helps keep the battery
charged.
STEERING COLUMN LOCK
Engaging
The steering column lock will engage
5 seconds after removing the electron-
ic key from the ignition device and if the
following conditions are present:
❒engine off;
❒instrument panel off with car at a
standstill;
❒electronic key removed from ignition
device.
Disengaging
The steering column lock will disengage
after fitting the electronic key into the
ignition device.
IMPORTANTSwitching the engine off
when the car is running will not engage
the steering column lock till next switch-
ing off with car stopped. In this event
warning light
>(where provided) on the
instrument panel will come on (or as an
alternative, on certain versions, a sym-
bol and a message are displayed).
IMPORTANTSteering column lock
failure is indicated by the instrument
panel warning light
>(where provid-It is absolutely forbid-
den to carry out what-
ever after-market operation
involving steering system or
steering column modifications
(e.g.: installation of anti-theft
device) that could badly affect
performance and safety, cause
the lapse of warranty and al-
so result in non-compliance of
the car with homologation re-
quirements.

MANUAL INSTRUMENT
PANEL LIGHT DIMMER
With this function it is possible to adjust
on 8 levels the light intensity of the indi-

play, sound system display (where pro-
vided), climate control system display, ra-
dionavigation system display (where pro-
vided), and instrument panel gauges (fu-
el level gauge, engine oil temperature
gauge (petrol versions) or supercharger
pressure gauge (diesel versions) and en-
gine coolant temperature gauge).
To increase light intensity press briefly
button+on the left-hand stalk, to re-
duce it press button –: the display will
show an indication and a figure corre-
sponding to the current light intensity
level. This screen will be displayed for
a few seconds and then it will go off.
ENGINE OIL
TEMPERATURE GAUGE
(petrol versions) fig. 18
This shows the temperature of the en-
gine oil and begins working when the
oil temperature exceeds approx. 70°C.
If the pointer reaches the red sector, re-
duce your demand on the engine.
The turning on of the warning light
`
when travelling (on certain versions to-
gether with a message on the display)
indicates that the oil temperature is too
high; in this case, stop the engine and
contact Alfa Romeo Authorized Services.

Climate control system
√is very use-
ful to speed up window demisting and
it is therefore to be turned on in the
event of considerable moisture. In any
case it is recommended to perform the

❒turn knob Cto second speed;
❒turn knob BtoQ.

This function is timed and switches off
automatically after few minutes, or by
pressing again the button or by turning
the engine off. It will not be switched
on automatically when restarting the en-
gine.
IMPORTANTDo not apply stickers on
the inside of the heated rear window

LOOKING AFTER THE
SYSTEM
During the winter, the climate control
system
√must be turned on at least
once a month for about ten minutes.
Before summer, have the system
checked at Alfa Romeo Authorized Ser-
vices.
RECIRCULATION
To turn this function on press button
v: the button led will turn on.
This function is particularly useful when
the outside air is heavily polluted (in a
traffic jam, tunnel, etc.) However, it is
better not to use it for long periods, es-
pecially if there are several people in the
car to prevent window misting up.
Do not use the air recirculation function
on rainy/cold days as it would consid-
erably increase the possibility of the win-
dows misting inside.
IMPORTANTThe inside air recircula-
tion system makes it possible to reach
the required (“heating” or “cooling”)
conditions faster.After connecting/dis-
connecting the battery,
wait for 3 minutes at
least before fitting the electronic
key into the ignition device in
order to allow the climate con-
trol system control unit to reset
the positions of the electric ac-
tuators that adjust air temper-
ature and distribution.

AUTOMATIC TWO-/
THREE-ZONE
CLIMATE CONTROL
SYSTEM
(where provided)
DESCRIPTION
The car is fitted with a two-/three-zone
climate control system which makes it
possible to separately adjust the air tem-
perature in the two/three passenger’s
compartment areas to reach the required
comfort.
For top quality temperature control in
the two/three areas of the passenger's
compartment, the system is fitted with
external temperature sensor, passen-
ger's compartment temperature sensor
and two-side sun radiation sensor.
The climate control system automatically
controls and adjusts the following pa-
rameters and functions:
❒air temperature at driver/passengers
vents;
❒fan speed;
❒air distribution at driver/passenger
vents;
❒compressor activation;
❒air recirculation.
The following parameters and functions
can be set or changed manually:
❒required temperature;
❒fan speed;
❒air distribution on seven levels ;
❒compressor on/off;
❒window demisting/defrosting;
❒air recirculation;
❒one-zone function.
The system is fitted with AQS (Air Qual-
ity System) sensor (where provided),
that turns on air recirculation automati-
cally when it detects the presence of out-
side polluted air (for example in queues
and tunnels).
Where provided, the system also features
a demisting sensorA-fig. 48 ( set be-
hind the driving mirror), capable of mon-
itoring a preset area of the internal wind-
screen pane and to cut in automatically
to prevent or to reduce misting up through
a suitable strategy.
A0E0091mfig. 48
This sensor can be disabled by any man-
ual control and it is activated each time
the engine is started and in any case
when the user presses one of the AUTO
buttons.
