SELESPEED
TRANSMISSION
The car may be fitted with a mechanical
transmission with electronic control called
“Selespeed”.
The Selespeed considerably simplifies use
of the car, reducing the fatigue of city dri-
ving or when frequent gearshifting is re-
quired, at the same time offering brilliant
performance.
IMPORTANTTo be able to use the Se-
lespeed 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 electrohydraulic 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.
Gearshifting takes place through the con-
trol lever (A-fig. 96) which is of the float-
ing type with a “single central stable posi-
tion”.
Using the lever it is possible to request an
increase/decrease of the gear ratio engaged
and/or reverse gear engagement (R) or
neutral (N).There are also two stalks on the steering
wheel spokes (fig. 97) through which, on-
ly with the car on the move (with speed
above 2 km/h), it is possible to shift gear
up or down.
The gearbox can work in two operating
modes:
– the first is semiautomatic (MANUAL),
in which the driver directly requests gearshift-
ing through the lever on the centre console
or pressing the buttons at the steering
wheel;
– the second is automatic, called CITY,
in which the system decides directly when
to shift gear (mode selectable with the spe-
cific button A-fig. 98).

WARNINGS
– 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 onlywhen more con-
trol is needed for moving off manoeuvres at
low speed;
– if, in reverse gear, first gear is engaged
or vice versa, shift gear only when the car
is stopped completely and with the brake
pedal pressed.
Though highly unadvisable, if when trav-
elling downhill for some unexpected reason
the car is set to neutral (N), when the en-
gagement of a gear is requested the system
automatically engages the best gear in re-
lation to the speed of the car to allow the
correct transmission of torque to the wheels.When travelling downhill with a gear en-
gaged and the accelerator released (if the
vehicle 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 overheating occurs while the ve-
hicle is being started; in this case it is nec-
essary to “force” starting avoiding hesita-
tion or, if the car is on a slope, release the
accelerator and use the brake pedalto stop
the car;
– the car moves in the opposite direction
to the gear engaged, (e.g.: it moves for-
wards with reverse gear engaged; in this sit-
uation it is necessary to stop the car and en-
gage the correct gear, keeping the brake
pedal pressed.
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 minutes;
– the driver’s door is opened and the ac-
celerator and brake are not touched for at
least 1 second.
STOPPING THE CAR
To stop the car, simply release the accel-
erator pedal and, if necessary press the
brake pedal.
Regardless of the gear engaged and the
operating mode activated (MANUALor
CITY) the system automatically disengages
the clutch and shifts to a lower gear.
If deciding to move off again without hav-
ing stopped the car completely, the most
suitable ratio will be available for acceler-
ating again.
Stopping the car the system automatical-
ly engages first gear (1).

117
In the “MANUAL” operating mode there
are certain automatic/security devices which
simplify driving:
– when slowing down the clutch is opened
and the transmission ratio is automatically
reduced to be ready for picking up again;
otherwise, when the car is stopped, the
gearbox will automatically be in firstgear
(1);
– requests to change gear that would take
the engine to above maximum speed or be-
low minimum speed are not accepted;
– if jamming occurs during gear engage-
ment, the system firstly tries to engage the
gear required again and, if it is still not pos-
sible, it automatically engages the imme-
diately higher one to avoid leaving the car
inneutral.
IMPORTANTIt is advisable to wait for
the end of a gear shifting operation before
requesting another one, to avoid multiple
requests in rapid succession.AUTOMATIC OPERATION (CITY)
The automatic operating mode CITYis se-
lected pressing button (A-fig. 106) at the
base of the gearshift lever.
In addition to the gear, the reconfigurable
multifunction display shows the word CITY
(fig. 99).
The system decides directly when gearshift-
ing according to the engine running speed
and the driving style.
Releasing the accelerator pedal quickly, the
system does not engage a higher gear in or-
der to maintain an adequate level of engine
brake.
FAILURE WARNING
Failures of the Selespeed gearbox are shown
by the
twarning light (fig. 100) con-
nected with the associated failure message,
both shown on the display.
When the system is turned on (turning the
ignition key to MAR), the warning light
should turn on glowing steadily for about
4 seconds and then turn off.If the warning light stays on it means that
a fault to the gearbox has been detected; at
the same time a buzzer sounds intermit-
tently for 4 seconds to attract the driver's
attention.
In the case of a fault to the gearshift con-
trol lever, the system automatically engages
the automatic operating mode CITYto
make it possible to reach the nearest Alfa
Romeo Authorised Service to have the fault
eliminated.
In the case of a fault to other gearbox com-
ponents, the system only allows the en-
gagement of certain gears: first gear (1),
second gear (2) and reverse (R).
If warning light tand
the message appear on the
display, contact Alfa Romeo Au-
thorised Services as soon as pos-
sible to have the fault eliminated.

CLR (Clear)
Function with which it is possible to clear
all the tracks of the CD stored with the TPM
function.
EON (Enhanced Other Network)
Function that allows the radio to tune au-
tomatically on a different radio station than
the one being listed to which broadcasts traf-
fic information.
Fader
Function with which it is possible to ap-
propriately adjust the sound from the front
or rear speakers.
Hicut (Treble reduction)
Function with which it is possible to reduce
the treble tones, in accordance with the sig-
nal transmitted.Distant/Local (Sens Dx/Loc)
These are the two levels of reception sen-
sitivity.
1) Distant (maximum sensitivity), which
makes it possible to tune all the stations that
can be received.
2) Local (minimum sensitivity), which
makes it possible to tune only those stations
with sufficiently strong signals, such as for
example local stations.
Loudness
A function that automatically emphasises
the bass and treble tones when listening, at
low level. It is cut off with the volume set
to the maximum.
Mix
This function is used to randomly select a
Compact Disc among those present in the
loader and all the tracks on this Compact
Disc are played in random sequence.MSS
(Searching previous/next track)
With this function it is possible to listen to
the next or previous track on the cassette.
Mute
Function which, if activated, for example
in the presence of a cell phone in the car,
brings the volume to zero when a phone call
is being made/received.
Presettings
Number of radio stations that can be stored
manually or automatically.
PTY (Program Type)
This function allows the presetting of a cat-
egory of programmes such as for instance,
news bulletins, music, sport, etc. The set au-
tomatically gives priority to the type of pro-
gramme selected when transmission starts,
interrupting the one in progress.
