Button volume (Button volume adjustment)
With this function it is possible to adjust (to eight levels) the vol-
ume of the acoustic signal sounding when the MENU SET button
is long pressed to exit a sub-menu and return to the standard menu.
To set the desired volume, proceed as follows:
– briefly press the SET ESC button: the previously set volume lev-
el will be displayed;
– press the button “
Ò▲“ or “▼“ to adjust the volume; an
acoustic signal equal to the volume level being selected is sound-
ed during this adjustment;
– briefly press the SET ESC button to go back to the previous screen
or hold the button down to go back to the standard screen with-
out saving.
On versions with reconfigurable multifunction display, the volume
level is represented by bars.
Belt reminder (Buzzer/reactivation for S.B.R.
signally)
(for versions/markets, where provided)
This function will only be displayed after the S.B.R. system
has been deactivated by an Alfa Romeo Authorised Service Provider
(see “S.B.R. system” in chapter 2).
Ser vice (Ser vice schedule)
With this function is possible to view information on servicing dead-
lines depending on kilometres travelled or daily intervals. The Ser-
vice function also shows the interval (in kilometres or miles) be-
fore the next engine oil change is due.
This information can be consulted as follows:
– briefly press the SET ESC button, which makes the display show
the service interval in km or mi according to the previous setting
(see “Distance measures” paragraph); press the SET ESC button
to return to the menu screen or hold the button down to return to
the standard screen.
IMPORTANT According to the “Planned Maintenance Programme”,
the car must be serviced every 30,000 km (1.4 petrol versions)
or 35,000 km (1750 Turbo petrol and diesel versions). This mes-
sage is displayed automatically when the key is turned to MAR,
from 2,000 km (or equivalent value in miles) when the next ser-
vice is due and is displayed again every 200 km (or equivalent
value in miles). Below 200 km the signals become more frequent.
The indication will appear in kilometres or miles depending on
the unit of measurement settings. When the next scheduled ser-
vice is approaching and the key is turned to MAR, the word Ser-
vice will appear on the display, followed by the number of kilo-
metres or miles left. Contact Alfa Romeo Authorized Services where
the “Planned Maintenance Programme” operations will be per-
formed and the message will be reset.

Values displayed
Autonomy
This indicates the approximate distance which can be travelled with
the present amount of fuel in the tank.
The display will show the reading “- - - -“ when the following events
take place:
– range is lower than 50 km (or 30 mi)
– car left parked with engine running for a long time.
IMPORTANT The autonomy value variation can be affected by sev-
eral factors: driving style, type of route (motorway, towns and
cities, mountain roads, etc.), conditions of use (load, tyre pres-
sures, etc.). Take these factors into account when planning a trip.
Distance travelled
This shows the distance covered from the start of the new journey.
Average consumption
This value is the approximate average fuel consumption from the
start of the new journey.

SYMBOLS
Some components of the car have coloured labels whose sym-
bols indicate precautions to be observed when using this compo-
nent. Under the bonnet there is also a label that summarises all
the symbols.
ALFA ROMEO CODE SYSTEM
This is an electronic engine locking system which increases pro-
tection against attempted thefts of the car. It is automatically ac-
tivated when the ignition key is extracted.
Each key contains an electronic device which modulates the sig-
nal emitted during ignition by an antenna built into the ignition de-
vice. This signal is the ‘password’ which changes at each ignition
and which the control unit uses to recognise the key and enable
ignition.
OPERATION
The Alfa Romeo CODE system control unit sends an acknowl-
edgement code to the engine management control unit to deacti-
vate the inhibitor each time the car is started by turning the igni-
tion key to MAR.
The code is sent only if the Alfa Romeo CODE system control unit
has recognised the code transmitted from the key.
Each time the ignition key is turned to STOP, the Alfa Romeo
CODE system deactivates the functions of the engine management
control unit. Warning light
Ylights up on the instrument panel
if the code is not correctly recognised during ignition.
In this case, turn the key to STOP and then to MAR; if it is still
locked, try again with the other keys that come with the car. If you
are still unable to start the engine contact Alfa Romeo Authorized
Services.

ALARM(for versions/markets, where provided)
OPERATION OF THE ALARM
The alarm intervenes in the following instances:
❍unauthorised opening of doors/bonnet/boot (perimeter pro-
tection);
❍unauthorised operation of ignition system (ignition key rotat-
ed to MAR);
❍the battery cables cutting;
❍when someone is moving inside the passenger compartment
(volumetric protection);
❍anomalous lifting/tilting of the vehicle (for versions/markets,
where provided).
Operation of the alarm is indicated by an acoustic and visual sig-
nal (flashing of the direction indicators for several seconds). The
alarm triggering modes may vary according to the markets. There
is a maximum number of acoustic/visual cycles. When this is
reached the system returns to normal operation.
IMPORTANT The engine locking function is guaranteed by the Alfa
Romeo CODE, which is automatically activated when the ignition
key is extracted from the ignition switch.
IMPORTANT The alarm is configured to comply with the regulations
existing in different countries.
SWITCHING ON THE ALARM
With the doors and bonnet closed and the ignition key either turned
to STOP or removed, direct the key with the remote control to-
wards the car, then press and release
Ábutton. Except specific
markets, the system produces a visual and acoustic signal and
enables door locking.
A self-diagnostic stage precedes the turning on of the alarm: In case
of faults the system will generate a further acoustic and/or visu-
al signal using the LED on the dashboard.
If after the alarm is switched on, a second acoustic signal is emit-
ted and/or the LED on the dashboard flashes, wait about 4 sec-
onds and switch off the alarm by pressing
Ëbutton, check that the
doors, bonnet and boot are closed correctly and then reactivate the
system by pressing
Ábutton.
If the alarm produces an acoustic signal even when the doors, bon-
net and boot are correctly closed, a fault has occurred in system
operation: in this case, go to Alfa Romeo Authorized Services.
ALARM SELF-ACTIVATION
(for versions/markets, where provided)
If the alarm has not been activated using the remote control, once
about 30 seconds have elapsed from when the ignition key was
turned to STOP and a door or the tailgate was last opened and
then closed, the alarm activates automatically. This is indicated
by the LED on the button A-fig. 20 lighting up intermittently and
the indications of activation described previously.
To deactivate the alarm, press the
Ëbutton on the remote control.
The alarm also activates when the doors are closed by turning
the metal insert of the key in the driver side door latch. If the sys-
tem self-activates, the doors are not locked.

IGNITION SWITCH
The key can be turned to three different positions fig. 21:
❍STOP: engine off, key can be extracted, steering locked. Some
electric devices (e.g. car radio, central door locking system,
alarm, etc.) can work;
❍MAR: driving position. All electric devices can work;
❍ON: starting the engine.
The ignition switch is fitted with an electronic safety system that
requires the ignition key to be turned back to STOP if the engine
will not start, before the starting operation can be repeated.
fig. 21A0K0063m
If the ignition switch is tampered with (e.g.: at-
tempted theft), have it checked over by an Alfa
Romeo Authorised Service Provider as soon as pos-
sible.
Always remove the key when you leave your car
to prevent someone from accidentally operating
the controls. Remember to engage the handbrake.
Engage 1
stgear if the car is parked uphill or reverse if the
car is parked downhill. Never leave children unattended
in the car.
STEERING LOCK
Engagement
When the key is at STOP, remove the key and turn the steering
wheel until it locks.
Disengagement
Move the steering wheel slightly and turn the ignition key to MAR.
It is absolutely forbidden to carry out any after-
market operation involving steering system or
steering column modifications (e.g.: installation of
anti-theft device). This could badly affect performance and
safety, invalidate the warranty and also result in the non-
compliance of the car with approval requirements.
Never remove the key while the car is moving. The
steering wheel should lock automatically as soon
as it is turned. This also applies to when the car is
towed.

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.
