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).

Never remove the ignition
key when the car is mov-
ing. In addition to the fact
that the Selespeed system would
not work properly up to stopping
the car, the steering wheel would
lock automatically the first time it
is turned.
STARTING THE ENGINE
The engine can be started with the gear
engaged or in neutral (N), provided that the
brake pedal is pressed down.
IMPORTANTKeep the pedal fully de-
pressed during starting. Since the brake ped-
al becomes hard if it is pressed repeatedly
with the engine off, in this situation it is nec-
essary to increase the pressure on the ped-
al itself to start the engine.
After starting, the gearbox sets to neutral
automatically, the display shows the letter
(N) and the system selects the operating
mode memorised before switching off.
If the engine fails to start
with the gear engaged, the
driver is alerted of the po-
tentially dangerous situation due
to the fact that the gearbox has
automatically set to neutral by the
buzzer and the display.
SWITCHING OFF THE ENGINE
AND SYSTEM DEACTIVATION
Turning the ignition key to STOPthe en-
gine switches off: the gear selected before
turning the engine off remains engaged.
If the engine stops with the gearbox in
neutral (N), the buzzer and the blinking
of (N) draw the attention of the driver so
that the car can be put in safety conditions
engaging the first gear (1) or reverse (R).
In this case, it is necessary to turn the igni-
tion key to MARand with the brake ped-
al pressed, engage first gear (1) or reverse
(R).
NEVER leave the car with
the gears in neutral (N).
It is absolutely necessary
to turn off the engine con-
sequently deactivating the
Selespeed system keeping the brake
pedal pressed: release the pedal
ONLY when the display goes off.

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.

ABS
(on request for versions/markets
where applicable)
The car is fitted with an ABS braking sys-
tem, which prevents the wheels from lock-
ing when braking, makes full use of the grip
and within the limits of the grip available,
keeps the car controllable also in emergency
braking.
When braking a slight pulsing accompa-
nied by noise may be felt on the brake ped-
al due to the action of the ABS system.
This should not be interpreted as a brak-
ing malfunction. It is the signal to the driver
that the ABS has come into action: it is the
warning that the car is travelling at the lim-
it of its grip and therefore the speed should
be adapted to the type of road.
The ABS system is an additional part of the
base braking system; in the event of a fail-
ure it is disabled, leaving the braking sys-
tem in the same conditions as a car without
ABS.
In the case of a failure, the anti-lock action
is no longer present, the braking capacity of
the car is not adversely affected at all. The ABS better exploits
the grip available, but can-
not increase it; caution is
therefore necessary on slippery
surfaces, without taking unneces-
sary risks.
If the ABS cuts in it means
that the limit of the grip is
being reached between the
tyre and the road surface: it is
therefore necessary to slow down
to adapt driving to the grip avail-
able.
In the event of a system
failure, with the turning on
of the
>warning light on
the instrument cluster, have the car
checked immediately by Alfa
Romeo Authorised Services, to be
able to have the system restored
to fully efficient conditions.
If you have never previously used cars fit-
ted with ABS, it is advisable to practice a lit-
tle on a slippery surface, naturally in safe-
ty conditions and in accordance with the lo-
cal Highway Code; you are also advised to
read the following instructions carefully.
The advantage of the ABS over a conven-
tional system is that it makes it possible to ob-
tain the highest degree of handling also when
braking completely under limited grip condi-
tions, preventing the wheels from locking.
However, with the ABS do not expect the
braking distance to always shorten: for ex-
ample, on soft surfaces like gravel or fresh
snow or a slippery surface, the space might
increase.
To better exploit the possibilities of the an-
ti-lock system in the case of need, the ad-
vice given below should be followed.

GETTING TO KNOW YOUR CAR
135
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.
