CRUISE CONTROL(optional for versions/
markets where applicable)
GENERALThe speed regulator (CRUISE CON-
TROL), with electronic control, makes it
possible to drive the car at the required
speed without pressing the accelerator
pedal. This reduces driving fatigue on mo-
torways, especially during long journeys be-
cause the speed memorised is automatically
maintained.
WARNINGThe device can only be en-
gaged at speeds between 30 and 190
km/h.
The device may only be engaged in the
4th, 5
thor 6
thgear. Travelling downhill with
the device engaged, the car speed may in-
crease more than the memorised one, due
to the change in the engine load.The device is disengaged automatically in
any one of the following cases:
– pressing the brake pedal;
– pressing the clutch pedal;
– if the VDC, ASR system cuts in;
– with Selespeed or Q-System transmis-
sion if a gear is changed;
– if car speed is below the set limit.
CONTROLS
(fig. 79)
Cruise Control is controlled by the
ON/OFFknurled ring (A), by the +/-
ring (B) and by the RCLbutton (C).
Ring (A) has two positions:
– OFF: in this position the device is de-
activated;
– ON: is the normal operating position of
the device: the warning light
Ü
on the check
panel turns on.
Ring (B) serves for memorising and main-
taining the car speed or for increasing or low-
ering the speed memorised.
Turn the ring (B) to (+) to memorise the
speed reached or increase the speed mem-
orised.

GETTING TO KNOW YOUR CAR54
Turn the ring (B) to (–) to lower the speed
memorised.
Each time the ring is actuated (B) the
speed increases or lowers by about 1.5
km/h.
Keeping the ring turned the speed changes
continuously. The new speed reached will
be maintained automatically.
The RCLbutton (C) resets the memorised
speed.
WARNINGTurning the ignition key to
STOPor the ring (A) to OFF, the speed
memorised is cleared and the system is
switched off.
The ring (A) can be constantly left to ON
without damaging the device. However, we
suggest to disconnect the device when it is
not used, turning the ring to OFF, to avoid
fortuituous speed memorisations.
TO MEMORISE THE SPEEDMove the ring (A) to ONand take the car
to the required speed normally. Turn the ring
(B) to (+) for at least three seconds, then
release it. The car speed is memorised and
it is therefore possible to release the accel-
erator pedal.
The car will continue to travel at the mem-
orised constant speed until one of the fol-
lowing condition takes place:
– pressing the brake pedal;
– pressing the clutch pedal;
– if the VDC, ASR system cuts in;
– with Selespeed or Q-System transmis-
sion if a gear is changed.
WARNINGIn the case of need (when
overtaking for instance) acceleration is pos-
sible simply pressing the accelerator pedal;
later, releasing the accelerator pedal, the car
will return to the speed memorised previ-
ously.
TO RESET THE MEMORISED
SPEEDIf the device has been disengaged for ex-
ample pressing the brake or clutch pedal,
the memorised speed can be reset as fol-
lows:
– accelerate gradually until reaching a
speed approaching the one memorised;
– engage the gear selected at the time
of speed memorising (4
th, 5
thor 6
thspeed);
– press the RCLbutton (C).

To release the hand brake:
– slightly lift the lever (A) and press the
release button (B);
– holding the button down lower the lever.
The
x
warning light on the instrument
panel will go out.
To prevent the car from moving acciden-
tally, keep the brake pedal pressed when
engaging the handbrake.WARNINGThe handbrake lever (A) is
fitted with a safety device which prevents
the brake from being released when, if the
lever is pulled, button (B) is pressed. There-
fore, to release the brake, in addition to
pressing button (B), it is also necessary to
pull lever (A) further upwards to release the
safety device, then lower the lever com-
pletely
GEARSHIFT LEVER
(fig. 123)
Depending on the versions the car is fitted
with a five or six speed mechanical gearbox
(see “Technical specifications” chapter).
The position of the individual gears is
shown by the pictogram on the gearshift
lever knob.
When changing gear, always fully depress
the clutch pedal. Before engaging reverse
gear (R) wait for the car to be stationary.

The wheels should be
locked after a few clicks of
the hand brake. If this does not oc-
cur, contact Alfa Romeo Authorized
Services to have the hand brake
adjusted.

For 2.5 V6 24V versions and Diesel ver-
sions, to engage reverse gear (R), it is nec-
essary to wait for the car to be stationary,
then raise the ring under the grip (with the
fingers of the same hand holding the lever).
After engaging reverse gear, release the
ring. It is not necessary to raise the ring on
the lever when shifting from reverse to an-
other gear.WARNINGReverse gear can only be en-
gaged with the vehicle completely stopped.
With the engine running, before engaging
reverse gear it is necessary to wait for at
least 3 seconds with the clutch pedal fully
pressed, to avoid grating and the possibil-
ity of damaging the gears.Do not drive with your
hand resting on the
gearshift lever, since the
applied pressure, though slight,
may, with the passing of time,
damage parts inside the gear.
To change gear smoothly,
the clutch pedal must be
fully depressed. Therefore, there
should be no hindrances under the
pedal unit. Make sure that any
mats are well laid and do not in-
terfere with the pedals.

Gearshifting takes place through a floating
control lever (A-fig. 124) with only one
stable central position. Using this lever it is
possible to request increase/decrease of the
ratio of the gear engaged and/or engage-
ment of reverse gear (R) or neutral (N).
There are also two levers on the steering
wheel spokes (fig. 125) through which,
only with the car on the move (with speed
above 0.5 km/h), it is possible to shift gear
up or down.
SELESPEED GEARBOX (optional for versions/markets
where applicable)
The 2.0 JTS engine can be supplied with
a mechanical gearbox with electronic con-
trol, called “Selespeed”.
The Selespeed considerably simplifies the
use of the car, it reduces driving fatigue in
town or when frequent gearshifting is nec-
essary, but at the same time it assures bril-
liant performance.WARNINGTo be able to use the Sele-
speed correctly, this chapter should be read
in full to understand the correct, permissible
operations to be carried out right from the
start.
This device comprises a conventional me-
chanical gearbox to which an electronical-
ly-operated electro-hydraulic device has been
added which automatically controls the
clutch and gear engagement.
The clutch pedal has been eliminated and
the vehicle moves off using only the accel-
erator pedal.

WARNINGOnce a gear has been shifted
it is necessary to release the gearshift con-
trol lever immediately after making the re-
quest. A prolonged action (over 10 seconds)
causes automatic shifting to CITY; previous
conditions are restored when releasing the
lever.
WARNINGIf 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 Infocenter display shows the
new gear engaged and then wait for 1 to
2 seconds before releasing the brake pedal
to allow complete clutch engagement.
fig. 129
A0B0274m
To put the gearbox in neutral (N), start-
ing from the condition with the vehicle sta-
tionary and the brake pedal pressed, it is
necessary to move the gearshift control lever
to the right (fig. 128).From any gear (N, 1, 2, 3, 4, 5) and
with the vehicle practically at a standstill,
it is possible to request engagement of re-
verse gear, pushing the lever to the right and
then backwards (fig. 129). If the vehi-
cle is on the move, the request is not ac-
cepted; wait for the car to stop and then
request reverse gear engagement againfig. 128

WARNINGS– With the vehicle stationary and a gear
engaged, always keep the brake pedal
pressed until you decide to move off;
– in prolonged stops with the engine run-
ning it is advisable to keep the gearbox is
neutral;
– when the car is parked on a slope, do
not use the pick-up manoeuvre to keep the
vehicle stopped; use the brake pedal and
work on the accelerator pedal only when
you decide to move off;
– use second gear onlywhen necessary
to obtain better control of pick-up in low
speed manoeuvres;
– 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. This should not be considered as a fault as
it is part of the operating logic. For the same
reason, in the event of sticking on reverse,
the system commands partial clutch closing
to allow engagement of the gear; in this
case engagement of reverse gear (R) will
be less comfortable.
Moving off of the vehicle is obtained:
1) releasing the brake pedal;
2) gradually operating the accelerator
pedal.
The vehicle pick-up torque is higher the
more the accelerator pedal is pressed.
MOVING OFFWith the engine running and the vehicle
stationary, 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 levers on the
steering wheel allow gear engagement only
over 0.5 km/h.
WARNINGReverse gear (R) can be en-
gaged from each of the following other ra-
tios: 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.
The driver is informed of the reverse gear
engaged condition by the intermittent sound
of the buzzer as well as by the display on
the rev counter.
WARNINGIf while shifting from reverse
(R)/first gear (1) to neutral (N)/first gear
(1) sticking occurs on the first gear, the sys-
tem automatically engages second gear
(2).
After a request to shift
gear with the vehicle sta-
tionary, before pressing the accel-
erator pedal to make the car start,
the driver must always check that
the gear engaged shown on the
display is the one required.

STOPPING THE CARTo stop the vehicle, simply release the ac-
celerator pedal and, if necessary, operate
the brake pedal.
Regardless of the gear engaged and of the
operating mode activated (MANUALor
CITY), the system automatically disen-
gages the clutch and downshifts gear.
If you intend to move off again without
having completely stopped the car, this way
the most suitable gear ratio for re-acceler-
ating will be available.
Stopping the vehicle, the system auto-
matically engages first gear (1). 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.
Downhill with the gear engaged and the
accelerator released (if the vehicle is trav-
elling), if a certain pre-established speed is
exceeded, the system automatically en-
gages the clutch to provide adequate engine
braking.
Due to safety reasons, the Selespeed sys-
tem activates the buzzer when:
– clutch overheating occurs during vehicle
starting; in this case, it is necessary to
“force” moving off avoiding hesitations or
to release the accelerator and use the brake
pedal to park the vehicle if the car is on a
slope;
– the car moves in the opposite direction
to the gear engaged, (e.g.: vehicle moving
forward with reverse engaged); in this sit-
uation it is necessary to stop the vehicle and
keeping the brake pedal pressed, engage
the gear correctly.Still for safety reasons, when the vehicle
is stationary, with the engine started and
gear (1), (2) or (R) engaged, the system
activates the buzzer and shifts to neutral
(N) automatically when:
– there is no action on the accelerator
and/or brake pedal for at least 3 minutes;
– the brake pedal is pressed for over 10
minutes;
– the driver’s door is opened and the ac-
celerator and brake pedal are not pressed
for at least 1 second.

When shifting gear, releasing the acceler-
ator pedal is not necessary because the Se-
lespeed system directly controls the engine
so as to:
– reduce and then increase the engine
torque;
– adapt the engine speed to the new gear
ratio engaged.
When downshifting, double de-clutching
(acceleration of the engine to bring it to the
speed necessary with the new gear ratio) is
carried out automatically.
The move to neutral (N) command is ac-
cepted when the car speed exceeds 20 km/h.
The command to engage reverse gear (R)
is accepted only if the car is stationary.With the accelerator pedal pressed by over
60% of its stroke and with an engine speed
of over 5,000 rpm, gearshifting becomes
quicker.
In the MANUALmode there are some
automatic/safety devices which make dri-
ving easier:
– when slowing down, the clutch is
opened and the gear ratio is reduced auto-
matically to be ready for possibly picking up
speed again; if not, stopping the vehicle,
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;– if the engine reaches the maximum per-
missible rpm and accelerating continues
(without coming into operation of the VDC
system), the system automatically engages
a higher gear; with the activation of the VDC
system, with the maximum engine rpm,
gear shifting is excluded;
– 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
vehicle in neutral speed.
WARNINGIt is advisable to wait for a
gearshift to end before requesting another
one, this will avoid multiple requests in quick
succession.
