SELESPEED GEARBOX FAILURETurning the ignition key to MAR, the warning light on the cluster shall come on and then go off af-
ter about 4 seconds. If the warning light stays on, it indicates that a fault has been detected in the Se-
lespeed gearbox; at the same time, the buzzer beeps intermittently for 4 seconds to draw the atten-
tion of the driver. Contact Alfa Romeo Authorised Services as soon as possible to remove the fault.Q-SYSTEM AUTOMATIC GEARBOX FAILURETurning the ignition key to MAR, the warning light on the cluster shall come on and then go off
after about 4 seconds. If the warning light stays on or turns on when travelling, it indicates over-
heated gearbox oil (glowing steadily) or a gearbox fault (flashing).
Warning light glowing steadily: it indicates that the gearbox oil has reached the maxi-
mum established temperature.
To make oil cooling down, stop the car, move the lever to Por Nand let the engine idle until the
warning light goes out. Resume driving without demanding high performance from the engine. If
the warning light comes on again, it is necessary to stop again with the engine idling until it goes
out again. If the interval between one lighting up of the warning light and next is below 15 minutes,
you are advised to stop the car, turn the engine off and wait for the engine-gearbox unit to cool down
completely. Contact Alfa Romeo Authorised Services as soon as possible.
Warning light flashing: it indicates a fault in the automatic gearbox.
The automatic control system provides an emergency programme. Under these circumstances,
you are advised to stop the car and turn the engine off; in fact, the next time the engine is started,
the self-diagnostic system could cut off the fault which will however be memorised. Conversely, if
the fault remains (warning light flashing), it is necessary to select the gears manually as if driving
a car with mechanical gearbox, bearing in mind that the only two speeds available are the 2
ndand
4
thgear. Contact Alfa Romeo Authorised Services as soon as possible.

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.

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.

Failures of Selespeed gearbox are signalled
to the driver through a warning light (B-fig.
126) accompanied by an acoustic signal. The gearbox can work in two operating
modes:
– the first is semiautomatic(then called
MANUAL), in which the driver directly re-
quests gearshifting through the lever on the
centre console or pressing the buttons at the
steering wheel;
– the second is automatic, calledCITY
(mode selectable with the specific button
B-fig. 124, the CITYsign appears on the
display fig. 126fitted on rev-counter), in
which the system decides directly when to
shift gear.With the gearbox in the CITYmode it is
still possible to carry out manual gearshift-
ing, both using the gear lever and the steer-
ing wheel controls. The gearbox remains in
the CITYmode.
The gear engaged (fig. 126) is always
signalled on the display regardless of the se-
lected mode.
N= neutral;
1= first gear;
2 = second gear;
3= third gear;
4= fourth gear;
5= fifth gear;
R= reverse.

SYSTEM ACTIVATIONWARNINGOpening the driver’s door,
the Selespeed starts the hydraulic part of
the system to prepare it for the engine to be
started. This function (noted by the turning
of the electric pump) is deactivated after 10
openings/closings of the door that are not
followed by actual system activation using
the ignition key.
Turning the ignition key to MAR, all the
segments of the display (A-fig. 126), the
gearbox failure warning light (B-fig. 126)
and the word CITYlight up. After about one
second, the display indicates the gear en-
gaged (N, 1, 2, 3, 4, 5, R); from this mo-
ment, the Selespeed system accepts
gearshift commands.
WARNINGIf after 10 seconds the dis-
play segment do not display the gear en-
gaged or the failure warning light stays on,
turn the ignition key to STOPand wait for
the display to go off, then repeat the sys-
tem activation procedure. If the fault per-
sists, contact Alfa Romeo Authorized Ser-
vices
OPERATION WITH THE
ENGINE OFFWARNINGBefore operating the gear-
shift control lever, always check the gear en-
gaged on the display (N, 1, 2, 3, 4, 5, R).
When the engine is off and the vehicle is
stationary, it is possible to engage all the
gears.
With the vehicle stationary and with the
brake pedal pressed, requests to shift gear
are accepted onlyif they are carried out
through the control lever on the central con-
sole.To request gearshifting, in addition to keep-
ing the brake pedal pressed it is necessary to:
– to increase gear (+) (fig. 127) push
the lever “forwards” (if the car is in first gear
this shifts to second, if it is in second gear
it goes to third and so on up to fifth). If the
system is in neutral (N) or reverse (R) the
forward movement on the lever causes en-
gagement of first gear (1).
– to shift down (–) (fig. 127) push the
lever backwards (if the car is in fifth gear
it moves to fourth, if fourth gear is engaged
it shifts to third and so on down to first).

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

STARTING THE ENGINEThe engine can be started with the gear
engaged or in neutral (N), provided that the
brake pedal is pressed down.
WARNINGKeep the brake pedal
pressed during the starting operation. As the
brake pedal stiffens if it is pressed repeat-
edly with the engine off, in this situation, to
allow the engine to be started, it is neces-
sary to increase the pressure exerted on the
pedal itself.
After starting, the gearbox automatically
sets to neutral, the display shows the let-
ter (N) and the system selects the operat-
ing mode stored before switching off.
TURNING THE ENGINE OFF
AND SYSTEM DEACTIVATIONTurning the ignition key to STOPthe en-
gine switches off but the Selespeed system
still remains active, waiting for the vehicle
to stop completely. After about 2 - 4 seconds
from when the key has been turned to the
STOPposition, the hydraulic part is deac-
tivated and immediately afterwards the dis-
play on the rev counteralso goes out ; the
Selespeed system is only deactivated at this
point.
The gear selected before turning the en-
gine off remains engaged.
If the engine stops with the gearbox in
neutral (N), the buzzer draws the attention
of the driver so that the vehicle can be put
in safety conditions engaging the first gear
(1) or reverse (R). In this case, it is nec-
essary to turn the ignition key to MARand
with the brake pedal pressed, engage first
gear (1) or reverse (R).
If the engine fails to start
with the gear engaged, the
driver is alerted of the potentially
dangerous situation due to the fact
that the gearbox has automatically
set to neutral by the buzzer and
the display on the rev counter.
WARNING
NEVER leave the car with
the gearbox in neutral (N).
WARNING
Never remove the key
when the car is on the
move, because in addition to the
fact that the Selespeed system
would not work properly until
stopping the car, the steering
wheel would automatically lock at
the first turn.
WARNING
It is absolutely necessary
to turn off the engine con-
sequently deactivating the Sele-
speed system keeping the brake
pedal pressed: release the pedal
ONLY when the display on the rev
counter goes off.
WARNING

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.
