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.

Though strongly inadvisable, if due to un-
foreseen circumstances when driving down-
hill the car is allowed to travel with the gear-
box in neutral (N), when the engagement
of a gear is requested, the system auto-
matically engages the best gear to allow
transmission of the torque to the wheels in
relation to the speed of the car.
When travelling downhill with a gear en-
gaged and the accelerator released (if the
car is moving), beyond a pre-established
speed, the system engages the clutch au-
tomatically to give the car adequate engine
braking.
For safety reasons the Selespeed system
activates the buzzer when: clutch over-
heating occurs during car starting; in this
case, it is necessary to “force” moving off
avoiding hesitations or to release the accel-
erator and use the brake pedal to park the
car if the car is on a slope.Still due to safety reasons, with the car sta-
tionary, the engine running and gear (1),
(2) or (R) engaged, the system activates
the buzzer and automatically shifts to neu-
tral (N) when:
– no action is made on the accelerator
and/or brake pedals for at least 3 minutes;
– the brake is pressed for over 10 min-
utes;
– the driver’s door is opened and the ac-
celerator and brake pedal are not pressed
for at least 1.5 seconds. IMPORTANT NOTES
– With the car stopped and a gear en-
gaged always keep the brake pedal pressed
until deciding to move off;
– during prolonged halts with the engine
running it is advisable to keep the gearbox
in neutral;
– when the car is parked facing uphill, do
not use the moving off manoeuvre to keep
the car still; use the brake pedal and press
the accelerator pedal only when deciding to
move off;
– use second gear only when more con-
trol is needed for moving off manoeuvres at
low speed;
– if, with reverse gear engaged, you need
to engage first gear or vice versa, shift gear
only when the car is completely stationary
and with the brake pedal pressed.

SEMIAUTOMATIC OPERATION
(MANUAL)
In the MANUALoperating mode the dis-
play shows the gear engaged.
In this operating mode, the decision to
change gear is left to the driver who decides
the most appropriate moment. The requests to change gear may take
place through:
– the control lever on the centre console
(A-fig. 124);
– the buttons on the steering wheel (fig.
125), which can be operated only when
the car speed exceeds 0.5 km/h.
TheMANUALoperating mode is set
when, with the CITYmode selected, the
CITYbutton (A-fig. 126) is pressed
again, thereby cutting out the previously se-
lected mode. When changing gear it is not necessary
to release the accelerator pedal because the
Selespeed system directly controls the en-
gine in such a way as to:
– reduce and then increase engine torque;
– adapt the engine speed to the new gear
ratio engaged.
When downshifting, the engine is accel-
erated automatically to bring it to the speed
necessary with the new gear ratio.
Neutral (N) is accepted until the car speed
exceeds 40 km/h.
The reverse gear engagement command
(R) is accepted only if the car is station-
ary.

With the accelerator pedal pressed to over
60% of its stroke and an engine speed
above 5000 rpm, gearshifting becomes
quicker. In the MANUALoperating mode
there are certain automatic/security devices
which simplify driving:
– when slowing down, the clutch is dis-
engaged and the gear ratio is reduced au-
tomatically to be ready for possibly picking
up speed again; if not, stopping the car, first
gear (1) will be engaged automatically;
– request to change gear that could take
the engine above the maximum rpm or be-
low the minimum permissible rpm are not
accepted;AUTOMATIC OPERATION (CITY)
TheCITYautomatic operating mode is se-
lected pressing the button (A-fig. 126)
at the base of the gearshift lever.
In addition to the gear, the display will
show the word CITY.
The system decides directly when to shift
gears in relation to the engine rpm and dri-
ving conditions.
Releasing the accelerator pedal quickly, the
system does not engage a higher gear in or-
der to maintain an adequate level of engine
brake.
fig. 126
A0A0701b
– if sticking occurs during the engagement
of a gear, the system firstly tries to engage
the required gear again and, if it is still not
possible, it automatically engages the im-
mediately higher one to avoid leaving the
car in neutral .
IMPORTANTIt is advisable to wait for
the end of a gear shifting operation before
requesting another one, to avoid multiple
requests in rapid succession.

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.

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.

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.

VDC SYSTEM
(Vehicle Dynamics Control)
(on request for versions/
markets where applicable)
The VDC is an electronic system that con-
trols car stability, intervening on the driving
torque and braking the wheels in a differ-
entiated manner, in the lack of grip, it helps
to bring the car back to the correct direction.
When travelling the car is subjected to lat-
eral and longitudinal forces which can be
controlled by the driver as long as the tyres
offer adequate roadholding; when this falls
below the minimum level, the car begins
to divert from the course required by the dri-
ver.
Especially when travelling on an uneven
surface (such as paving, or due to the pres-
ence of water, ice or soil), changes in speed
(acceleration or braking) and/or course
(bends or the need to avoid obstacles) may
cause the tyres to lose grip. When the sensors detect the conditions
that would lead to skidding, the system in-
tervenes on the engine and on the brakes
producing a stabilising torque.
HOW THE VDC
SYSTEM WORKS
System is engaged automatically when the
car is started and cannot be switched off.
The basic components of the system are:
– an electronic control unit that process-
es the signals received from the various sen-
sors and brings about the most appropriate
strategy;
– a sensor that detects the position of the
steering wheels;
– four sensors that detect the turning
speed of each wheel;
– a sensor that detects rotation of the car
around its vertical axis;
– a sensor that detects lateral acceleration
(centrifugal force).
The heart of the system is the control unit,
which with the data supplied by the sensors
installed on the car calculates the centrifugal
forces generated when the car is cornering.
The yawing sensor, which originates from the
aeronautical industry, detects the rotations
of the car around its own vertical axis. The
centrifugal forces generated when the car
is cornering are detected by a highly sensi-
tive lateral acceleration sensor. The performance of the
system, in terms of active
safety should not induce
the driver to take pointless and un-
necessary risks. The style of dri-
ving must in any case always be
adapted to the conditions of the
road surface, visibility and traffic.
The responsibility for road safety
is always and in any case the dri-
ver’s.
System helps the driver to keep the car un-
der control in the event of a loss of tyre grip.
The forces induced by the system to con-
trol the loss of car stability always depend
on the grip between the tyre and the road
surface.

GETTING TO KNOW YOUR CAR
137
The stabilising action of the system is
based on the calculations of the system elec-
tronic control unit, which processes the sig-
nals received from the steering wheel rota-
tion sensor, acceleration sensor and rotation
speed sensor of each wheel. These signals
allow the control unit to recognise the ma-
noeuvre the driver intends to do when the
steering wheel is turned.
The control unit processes the information
received from the sensors and therefore is
able to know the position of the car instant
by instant and compares it with the course
the driver would like to follow. In the event
of a discrepancy, in a fraction of a second
the control unit chooses and commands the
most suitable intervention to bring the car
immediately back to the required course:
braking one or more wheels at different in-
tensity and, if necessary, reducing the pow-
er transmitted by the engine.
The corrective actions are modified and
controlled continuously in seeking the course
required by the driver.
The action of system considerably en-
hances the active safety of the car in very
critical situations and it is particularly help-
ful when the grip conditions of the road sur-
face change. For the VDC system to
work correctly, the tyres
must be of the same brand
and type on all wheels, in perfect
conditions and above all of the
specified type, brand and size. CUTTING IN
OF THE VDC SYSTEM
The cutting in of the system is indicated by
the flashing of the áwarning light on the
instrument cluster, to inform the driver that
the car is in critical conditions of stability and
grip.
VDC system failure warning
In the event of a failure the system dis-
engages automatically and the
áwarning
light on the instrument cluster turns on glow-
ing steadily, together with the message on
the reconfigurable multifunction display.
In the event of an system failure the car
behaves like a car not fitted with this sys-
tem: in any case it is advisable to contact
Alfa Romeo Authorised Services as soon as
possible.During use of the compact
spare wheel, the VDC sys-
tem continues working. It
should be borne in mind that the
spare wheel is smaller than a nor-
mal tyre, therefore its grip is low-
er than that of the other tyres of
the car.

SWITCHING ON
THE ASR FUNCTION
The ASR function switches on automati-
cally each time the engine is started.
When travelling the ASR can be switched
off and on again pressing switch (A-fig.
151).
When the function is turned off, the in-
strument panel warning light
Vturns on.
If the function is switched off when trav-
elling, it will turn on again automatically the
next time the engine is started.
fig. 151
A0A1107b
ASR SYSTEM
(Antislip Regulation)
(on request for versions/
markets where applicable)
The ASR function controls the car drive and
cuts in automatically every time one or both
driving wheels slip.
In slipping conditions, tow different control
systems are activated:
1) if slipping involves both driving wheels,
being caused by excessive power transmit-
ted, the ASR device cuts in reducing the pow-
er transmitted by the engine.
2) if slipping involves only one driving
wheel, the ASR system cuts in automatical-
ly braking the wheel that is slipping, with
an effect similar to that of a self-locking dif-
ferential.The performance of the
system in terms of active
safety should not induce
the driver to take pointless and un-
necessary risks. The style of dri-
ving must in any case be adapted
to the conditions of the road sur-
face, visibility and traffic. Road
surface is always the driver’s re-
sponsibility.
The action of the ASR is particularly help-
ful in the following circumstances:
– slipping of the inner wheel on a bend,
due to the effect of dynamic load changes
or excessive acceleration.
– too much power transmitted to the
wheels also in relation to the conditions of
the road safety.
– acceleration on slippery, snowy or frozen
surfaces.
– in the case of loss of grip on a wet sur-
face (aquaplaning).
