WING MIRROR AND
REARSCREEN
DEFROSTING/DEMISTING
BUTTON
(fig. 110)
Pressing button (9)
(turns on
demisting/defrosting of the rearscreen
and, if present, the wing mirror coils.
The turning on of this function is shown
by the turning on of the led on the button.
This function is timed and switches off
automatically after 20 minutes, or press-
ing the button again; the function is also
switched off when the engine is stopped
and will not be switched on again the next
time the engine is started.
IMPORTANTThe system automatical-
ly turns on rearscreen heating if the tem-
perature is below 3°C.
IMPORTANTDo not apply stickers on
the inside of the rearscreen over the heat-
ing filaments to avoid damage that might
cause it to stop working properly.
POLLEN FILTER
Have the conditions of the filter checked
by Alfa Romeo Authorised Services at least
once a year, preferably at the onset of
summer.
If the car is used mainly in dusty or pol-
luted areas it should be checked and, if
necessary, replaced at shorter intervals.

The filter has the specific capability of fil-
tering external air, thus admitting to the
passenger compartment purified air, free
from particles such as dust, pollen, etc.
In addition to the above mentioned func-
tions, is also reduces the concentration of
pollutants.
The filtering action takes place under all
air inlet conditions and it is clearly most
effective with the windows shut.If the filter is not replaced
the efficiency of the cli-
mate control system may
be seriously compromised up to
blocking the air flow at the outlets
and vents.

If the car is on the move, the request is
not accepted; wait for the car to stop and
then request reverse gear engagement
again.
IMPORTANTOnce a gear has been
changed it is necessary to immediately re-
lease the gearshift control lever after mak-
ing the request. A manoeuvre prolonged
(over 10 seconds) makes the system au-
tomatically switch to CITYmode; every-
thing stops releasing the gearshift lever.
IMPORTANTIf wanting to leave the car
parked on a sloping road with a gear en-
gaged to keep it braked, it is necessary to
check that the display shows the new gear
engaged and then wait for 1 to 2 seconds
before releasing the brake pedal to allow
complete clutch engagement.

OPERATION WITH ENGINE OFF
IMPORTANTBefore using the gearshift
control lever, always check the gear en-
gaged on the display (N,1,2,3,4,5,
R).
With the engine off and the car station-
ary it is possible to engage all the gears.
With the car stationary and with the brake
pedal pressed, requests to shift gears are
both accepted through the control lever on
the central console or through the steering
wheel levers.
To request gearshifting, in addition to keep-
ing the brake pedal pressed:
– to shift upwards (+) (fig. 121) push
the lever “forwards” (if the car is in first gear
it shifts to second, if in second it shifts to
third and so on up to fifth). If the system
is in neutral (N) or reverse (R) moving thelever forwards causes the engagement of
first gear (1).
– to shift downwards (–) (fig. 121)
push the lever backwards (if the car is in
fifth gear it shifts to fourth, if in fourth it
shifts to third and so on down to first gear).
To allow setting the transmission to neu-
tral (N), starting from the condition with
the car stationary and brake pedal pressed,
move the gearshift lever to the right (fig.
122).
From any gear (N,1,2,3,4,5) and
with the car practically at a standstill, it is
possible to request engagement of reverse
gear, pushing the lever to the right and then
backwards (fig. 123).

The driver is informed of the reverse gear
engaged condition by the intermittent sound
of the buzzer as well as by the display.
IMPORTANTIf while shifting from re-
verse (R)/first gear (1) or neutral (N)/
first gear (1) sticking occurs on the first
gear, the system automatically engages sec-
ond gear (2).
This should not be considered a failure be-
cause it is part of the operating logic. For
the same reason, if sticking occurs on re-
verse gear, the system controls partial clutch
closing so that the gear can be engaged;
in this case the engagement of reverse gear
(R) will not be as smooth as usual. After a request to shift
gear with the car station-
ary, before pressing the ac-
celerator pedal to make the car
start, the driver must always check
that the gear engaged shown on
the display is the one required. MOVING OFF THE CAR
With the engine running and the car sta-
tionary, the gears that can be engaged for
moving off are only first (1), second (2) or
reverse (R).
To engage them it is possible to use the
control lever on the centre console, with the
brake pedal pressed, as the steering wheel
levers allow gear engagement only over 0.5
km/h.
IMPORTANTReverse gear (R) can be
engaged from each of the following other
ratios: neutral (N), first gear (1) or second
gear (2). If the car is on the move, the re-
quest is not accepted; it is necessary to wait
for the car to be completely stopped and
then request reverse (R) again. Moving off the car is obtained:
1) releasing the brake pedal;
2) gradually pressing the accelerator ped-
al.
The more the accelerator pedal is pressed
the higher the car pick-up torque will be.

PARKING THE CAR
To park the car safely it is absolutely nec-
essary to engage first gear (1) or reverse
(R) and also the handbrake if the road is
on a slope.
Turning the engine off with the car facing
uphill and a gear engaged, it is absolutely
necessary to wait for the gear display to go
off before releasing the brake pedal, so that
the clutch is fully disengaged.
If the gearbox is in neutral (N) and want-
ing to engage a parking gear, the system
should be activated and with the foot on the
brake pedal it is necessary to engage (1)
or (R).
TOWING THE CAR
IMPORTANTFor towing the car, adhere
to local regulations. Make sure that the gear-
box is in neutral (N) (checking that the car
moves when pushed) and proceed as for
towing a normal car with mechanical gear-
box following the instructions given in sec-
tion “In an emergency”.
If setting to neutral is not possible, do not
tow the car and contact Alfa Romeo Autho-
rized Services.
While towing the car do
not start the engine.
BUZZER WARNINGS
The buzzer is activated when:
– reverse gear is engaged (R);
– the car is parked with the gearbox in
neutral (N); signal that can be noted turn-
ing the ignition key to STOP;
– clutch overheating occurs when moving
off;
– the system has shifted automatically
to neutral (N) when:
there is no action on the accelerator
and/or brake pedal for at least 3 minutes;
or the brake is pressed for over 10 min-
utes;
or the driver’s door is opened and no ac-
tion is made on the accelerator and brake
for at least 1.5 seconds;
or detection of a gearbox fault;
– gearbox fault.

Carry out this operation
only with the car station-
ary.
DANGER-SERIOUS IN-
JURY. When carrying out
checks or maintenance op-
erations in the engine compart-
ment, take special care not to bump
the head on the raised bonnet.
If checks need to be car-
ried out in the engine com-
partment when the engine
is still warm, keep away from the
fan as it could start up even when
the key is removed from the igni-
tion. Wait until the engine cools
down.
BONNET
The bonnet opening lever is under the left
end of the dashboard.
To open:
– pull the lever (A-fig. 146) until the
bonnet clicks open.
– press the safety lever (A-fig. 147)
upwards.
– raise the bonnet.
IMPORTANTBonnet raising is aided by
two gas springs. Do not tamper with these
springs and accompany the bonnet while
raising it.
fig. 146
A0A0135b
Scarves, ties and loose
clothing may be caught in
the moving parts.
For safety reasons the
bonnet must be closed
properly to avoid its open-
ing while the car is travelling.
Therefore, always check it is prop-
erly closed and the catch engaged.
Should you notice that the catch is
not perfectly engaged when trav-
elling, stop the car immediately and
close the bonnet.
To close:
– lower the bonnet until approx. 20 cm
from the engine compartment and then let
it drop, ensuring it is fully closed and not just
held in position by the safety catch.
If the bonnet does not close properly do
not push it down but open it again and re-
peat the above procedure.

Always take due care when braking on
bends, even with the help of the ABS.
The most important advice of all, howev-
er, is this:
When the ABS cuts in, and
you feel the pulsing on the
pedal, do not lighten the
pressure, but keep the pedal firm-
ly pressed with no fear; this way
you will stop in the least space
possible, compatibly with the con-
ditions of the road surface.
Following these instructions you will be
in the best braking condition under all cir-
cumstances.
IMPORTANTCars fitted with ABS may
only be fitted with the wheel rims, tyres and
brake linings of type and brand approved by
the Manufacturer.
The system is completed by the EBD (Elec-
tronic Brake Distributor) which distributes
the braking action through the control unit
and the ABS system sensors. The car is fitted with an
electronic braking distribu-
tor (EBD). If the
>andx
warning lights turn on simultane-
ously with the engine running, this
indicates an EBD system failure; in
this case with sharp braking the
rear wheels might lock too early,
with the possibility of skidding. Dri-
ving extremely carefully, go to the
nearest Alfa Romeo Authorised Ser-
vice to have the system checked.
The turning on of only the
>warning light with the
engine running normally in-
dicates a fault to the ABS system
only. In this case the braking sys-
tem is still efficient, though with-
out the aid of the anti-lock device.
Under these conditions perfor-
mance of the EBD system may be
reduced. In this case too, you are
advised to go immediately to the
nearest Alfa Romeo Authorised
Service to have the system checked
over, driving in such a way as to
avoid sharp braking.
If the low brake fluid lev-
el
xwarning light turns
on, stop the car immedi-
ately and contact the nearest Alfa
Romeo Authorised Service. Any
loss of fluid from the hydraulic sys-
tem will negatively affect the op-
eration of the braking system be it
of the conventional type or of the
type with ABS.
If the compact spare
wheel is used, operation of
the ABS system is cut off
and the
>warning light on the in-
strument cluster turns on.
IMPORTANTIf the battery is run down
the
>andxwarning lights might turn on
when starting the engine and go off after
starting. This should not be considered as
a fault but as a warning that during start-
ing the ABS is not active. The turning off
of the warning lights ensures normal system
operation.

EOBD SYSTEM
(upon request for versions/
markets where applicable)
The EOBD system (European On Board Di-
agnosis) allows continuous diagnosis of the
components of the car correlated with emis-
sions.
It also alerts the driver, by turning on the
warning light
Uon the instrument panel
(on certain versions together with message
+ symbol on the reconfigurable multifunc-
tion display), when these components are
no longer in peak conditions.
The objective is:
– to keep the system efficiency under con-
trol;
– to warn when a fault causes emissions
levels to increase;
– to warn of the need to replace deterio-
rated components.The system also has a diagnostic connec-
tor that can be interfaced with appropriate
tools, which makes it possible to read the
error codes stored in the control unit, to-
gether with a series of specific parameters
for engine operation and diagnosis. This
check can also be carried out by the traffic
police.IMPORTANTAfter eliminating the in-
convenience, to check the system com-
pletely, Alfa Romeo Authorised Services are
obliged to run a bench test and, if necessary,
road tests which may also call for a long jour-
ney.
If, turning the ignition key
to MAR, the warning light
Udoes not turn on or if,
while travelling it turns on glow-
ing steadily or flashing (on some
versions together with the mes-
sage + symbol on the reconfig-
urable multifunction display), con-
tact Alfa Romeo Authorised Ser-
vices as soon as possible.

CORRECT USE OF THE CAR
171
Never push, tow or coast
start the car. This could
cause fuel to flow into the
catalyst damaging it irreversibly.
Remember that the en-
gine brake and power
steering are not opera-
tional until the engine is started,
therefore, much greater effort than
usual is needed on the brake ped-
al and steering wheel. For cars with turbocharg-
er in particular, but for all
cars in general, sharp ac-
celerating should be avoided before
switching the engine off.
A “kick” on the accelerator
serves no purpose, consumes fuel
pointlessly and may cause serious
damage to the turbocharger im-
peller bearings.
EMERGENCY STARTING
If the Alfa Romeo CODE system does not
recognise the code transmitted by the igni-
tion key (warning light
Yon the instru-
ment cluster glowing on steadily) emer-
gency starting may be carried out using the
code of the CODE card.
For the correct procedure see the chapter
“In an emergency”.
IMPORTANTIf the engine turns off with
the car on the move, the next time it is start-
ed, the Alfa Romeo CODE warning light may
turn on(
Y). In this case, check that switch-
ing off and starting the engine again with
the car stationary, the warning light stays
off. If not, contact Alfa Romeo Authorised
Services.
ENGINE SWITCHING OFF
– Release the accelerator pedal and wait
until the engine reaches idle speed.
– Turn the ignition key to the STOPpo-
sition and switch off the engine.
IMPORTANTAfter a tiring journey it is
advisable to let the engine “get its breath
back” allowing it to idle a while to lower the
temperature in the engine compartment.
