MINISTERIAL
HOMOLOGATIONS
In keeping with the laws in force in
each country on the subject of radio fre-
quency, we point out that:
– the separate homologation numbers
for each market are given on the last
pages of this handbook before the alpha-
betical index (for some countries also ho-
mologation document);
– for markets in which the transmitter
needs to be marked with the homologa-
tion number, this has been stated on the
component.
(Depending on the versions/markets,
the code may also be marked on the
transmitter and/or on the receiver).
REMOTE CONTROL
DOOR LOCKING
SYSTEM
The system comprises a receiver and a
transmitter (remote control) incorporated
in the key (B-fig. 14). To lock/unlock
the locks, point the transmitter towards
the car, press and release the button
(C). If, when pressing the remote control
push-button (C), the led (A) (where re-
quired) issues just a short flash, replace
the batteries as described in the “The Al-
fa Romeo CODE system” paragraph.
IMPORTANT Should it be necessary
to programme additional remote controls,
contact Alfa Romeo Authorized Services.
IGNITION DEVICE
THE SWITCH (fig. 15)
The switch has four positions:
–STOP: engine switched off, key can
be removed, engine lock engaged, steer-
ing lock engaged, all services excluded a-
part from those powered directly (e.g.
hazard warning light I.C.S. system (ex-
cept climate control).
–ACC: position for using the cigar
lighter and of the I.C.S. system (except
climate control).
–MAR: drive position. The engine
lock is deactivated and all electrical de-
vices are powered.

D - Rev counter
The danger zone (red) indicates exces-
sively high engine revs. Do not drive for
long periods with the pointer in this area.
With the engine at idle speed, the rev
counter may indicate a gradual or sudden
speed increase depending on the cases;
this is normal as it occurs in the normal
operation, for example when the climate
control compressor is engaged or the fan.
In particular a slow change in speed helps
preserve the battery charge.
IMPORTANT Depending on the ver-
sions/markets of the car, the rev counter
may have danger sectors (red) of differ-
ent size and with different top of scale
values.
IMPORTANT The electronic ignition
control system gradually shuts off the
flow of fuel when the engine is “over-
revving” resulting in a gradual loss of en-
gine power. Moving the ignition key to MARthe
following warning lights and displays turn
on and go out after approx. 6 seconds:
1- Light failure
2- Low brake fluid and/or handbrake
engaged
3- Front brake pad wear
4- Low engine oil level
5- Fuel reserve
6- Maximum engine coolant fluid tem-
perature
7- Mileage recorder displayAny faults are signalled by the turning
on of the corresponding warning light for
approx. 15 seconds after the end of the
check.
2) Doors and boot open warning.
With the ignition key at MAR, if a led
of the car symbol (10) lights up, the cor-
responding door or the boot has not been
shut properly.
To repeat the check, with the ignition
key in the MARposition and the engine
off, press the button (A-fig. 84).

The passenger compartment climate
control (heating, cooling and ventilation)
can be used in the following ways:
– manual climate control, by selecting
the functions using the control panel but-
tons;
– automatic climate control, managed
by the system electronic control unit.ADJUSTING THE CENTRE
UPPER VENT
(fig. 89)
The upper vent is fitted with an open-
ing/closing control (A)
O= Completely open
●= completely closed.

fig. 89 The air is admitted to the passenger
compartment through a series of out-
lets/vents located on the dashboard, on
the front door panels, centre console and
floor as illustrated (fig. 88):
1Centre vents for demisting/defrosting
the windscreen
2Upper adjustable centre vent
3Central movable and adjustable out-
lets
4Movable and adjustable side outlets
5Vents for demisting/defrosting the
side windows
6Front seat floor vents
7Rear seat floor vents
8Rear seat adjustable and movable
outlets.

CLIMATE CONTROL UNITThe climate control sys-
tem uses “R134a”
coolant fluid which
meets current regulations on the
subject and which does not harm
the environment in the event of
leakage. Absolutely avoid the
use of other fluids which are in-
compatible with the system com-
ponents.
