Rain sensor (fig. 61)
The rain sensor (A), fitted only on cer-
tain versions, is an electronic device com-
bined with the windscreen wiper which has
the purpose of automatically adjusting the
number of wipes during intermittent opera-
tion, to the intensity of the rain.
All the other functions controlled by the
right-hand lever remain unchanged.
The rain sensor is activated automatically
moving the right-hand lever to position (B-
fig. 59) and it has a range of adjustment
that gradually varies between wiper sta-
tionary (no wiping) when the windscreen is
dry, to wiper at first continuous speed (con-
tinuous, slow) with heavy rain.Turning the knurled ring (F-fig. 59) it
is possible to increase the sensitivity of the
rain sensor, obtaining a quicker change from
stationary when the windscreen is dry, to
first continuous speed (continuous, slow).
Operating the windscreen washer with the
rain sensor activated (lever at position B)
the normal washing cycle is performed at
the end of which the rain sensor resumes its
normal automatic function.
Turning the ignition key to STOPthe rain
sensor is deactivated and the next time the
engine is started (MARposition) it will not
be reactivated even if the lever has remained
in position (B). In this case to activate the
rain sensor, simply move the lever to (A)
or (C) and then back to (B).
When the rain sensor is reactivated in this
way, the wiper performs at least one stroke,
even if the windscreen is dry, to indicate that
reactivation has occurred.
The rain sensor is located behind the inner
rear-view mirror in contact with the wind-
screen and inside the area cleaned by the
wiper and it controls an electronic control
unit which in turn controls the wiper motor. “INTELLIGENT WASHING” FUNCTION”
Pulling the lever towards the steering
wheel (instable position) operates the wind-
screen washer.
Keeping the lever pulled, with only one
movement it is possible to operate the wash-
er jet and the wiper at the same time; in-
deed, the latter comes into action auto-
matically if the lever is pulled for more than
half a second.
The wiper stops working a few strokes af-
ter releasing the lever; a further “cleaning
stroke” after a few seconds completes the
wiping operation.

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).

STARTING THE ENGINE
The engine can be started either with a
gear engaged or in neutral (N) provided
that the brake pedal is fully depressed.
IMPORTANTIf the brake pedal is not
depressed, the starter motor will not turn,
thus preventing the engine from being start-
ed.
After starting, the gearbox sets to neutral
automatically, the reconfigurable multifunc-
tion display shows the letter (N) and the
system selects the semiautomatic operating
mode (manual).
SWITCHING OFF THE ENGINE
AND SYSTEM DEACTIVATION
Turning the ignition key to STOPthe en-
gine turns off but the Selespeed system is
still active waiting for the car to stop com-
pletely. After about 2 - 4 seconds from when
the key has been moved to STOP, the hy-
draulic part is deactivated and the reconfig-
urable multifunction display is turned off im-
mediately afterwards; at this point is the Se-
lespeed system deactivated.
The gear selected before switching off the
engine remains engaged.
If the engine is stopped with the gearbox
in neutral (N), the buzzer calls the driver’s
attention so that the car can be put in safe-
ty conditions engaging first gear (1) or re-
verse (R). In this case, the ignition key
should be turned to MARand with the
brake pedal pressed, engage first gear (1)
or reverse (R).
IMPORTANTIf the engine is stopped
with the CITYmode engaged, this will be
stored by the system. Indeed, the next time
the engine is started, this condition will still
be active.IMPORTANTShould the engine go off
with the car on the move, the next time it
is started the Alfa Romeo CODE warning
light (Y) may come on. In this case check
that the warning light goes off turning the
engine off and on again with the vehicle sta-
tionary. If not contact Alfa Romeo Authorised
Services.
NEVER leave the car with
the gears in neutral (N).
WARNING
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 auto-
matically the first time it is turned.
WARNING
If the engine fails to start
with the gear engaged, the
driver is informed of the potential-
ly dangerous situation due to the
fact that the gearbox is in neutral
by the buzzer and by the reconfig-
urable multifunction display.

MOVING THE CAR
With the engine on and the car stationary,
the gears that can be engaged for moving
off are only first (1), second (2) and/or
reverse (R).
To shift gears, keep the brake pedal
pressed and use only the lever on the cen-
tre console since the stalks on the steering
wheel can be only operated if the car speed
exceeds 10 km/h.IMPORTANTReverse gear (R) can be
engaged from any of the following other ra-
tios: neutral (N), first (1) or second (2).
If the car is moving, the request is not ac-
cepted, it is necessary to wait for the car
to stop completely and request the en-
gagement of reverse again (R).
The driver is informed of the reverse gear
engaged condition by the reconfigurable
multifunction display on the instrument clus-
ter and by the intermittent sound of a
buzzer.
IMPORTANTIf when shifting from re-
verse (R)➞first (1) or neutral (N)➞first
(1) sticking occurs on first gear, the system
automatically engages second gear (2).
This is not to be considered as a fault as it
is part of the operating logic. For the same
reason, in the case of sticking on reverse
gear, the system partially closes the clutch
to allowgear engagement; in this case the
engagement of reverse gear (R) will not be
as smooth as usual.Moving off of the car is obtained:
1) releasing the brake pedal;
2) gradually pressing the accelerator pedal.
The more the accelerator is pressed the
higher the pickup torque.
When the ASR system is off (through the
relevant ASR OFF button) max pickup is ob-
tained (“sprint" starting)
It is absolutely necessary
to turn off the engine and
then turn off the Selespeed system
keeping the brake pedal pressed:
ONLY release the pedal when the
reconfigurable multifunction display
on the cluster has gone out.
WARNING
After a request to shift
gear with the car station-
ary, before pressing the accelera-
tor pedal to make the car move,
the driver must always check the
display to see that the gear en-
gaged is the one required.

OPERATION
The gearbox can work in two operating
modes:
– the first is semiautomatic (MANUAL),
in which the driver directly decides when to
shift gear.
– the second is completely automatic
(CITY), in which the system decides di-
rectly when to shift gear according to the
type of driving.
TheCITYmode can be selected by press-
ing the specific button CITYon the gearbox
lever knob; when this mode is selected, the
CITY sign appears on the display.
SEMIAUTOMATIC OPERATION
(MANUAL)
In the operating mode, the reconfigurable
multifunction display on the cluster 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. 104);
– steering wheel stalks (fig. 105),
which can be operated only when the car
speed exceeds 2 km/h.TheMANUALoperating mode is set
when, with the CITYmode selected, the
CITYbutton(A-fig. 106) is pressed
again, excluding the previously selected
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 latest
gear engaged.
When downshifting, the engine is accel-
erated automatically to bring it to the speed
necessary with the new gear ratio.
The neutral command (N) is accepted un-
til the vehicle speed exceeds 40 km/h. The
reverse gear engagement command (R) is
accepted only if the vehicle is stationary.

VDC SYSTEM
(Vehicle Dynamics Control)
The VDC is an electronic system that con-
trols vehicle stability, intervening on the dri-
ving torque and braking the wheels in a dif-
ferentiated 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 VDC system
intervenes on the engine and on the brakes
producing a stabilising torque.
HOW THE VDC
SYSTEM WORKS
The VDC system is engaged automatical-
ly when the car is started and cannot be
switched off.
The basic components of the VDC 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 wheel;
– 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 VDC system is the VDC
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, de-
tects the rotations of the car around its own
vertical axis. The centrifugal forces gener-
ated when the car is cornering are detect-
ed by a highly sensitive lateral acceleration
sensor. The VDC system helps the driver to keep
the car under control in the event of a loss
of tyre grip.
The forced induced by the VDC system to
control the loss of vehicle stability always
depend on the grip between the tyre and
the road surface.
The performance of the
system, in terms of active
safety should not induce the driver
to take pointless and unnecessary
risks. The style of driving must in
any case always be adapted to the
conditions of the road surface, vis-
ibility and traffic. The responsibil-
ity for road safety is always and
in any case the driver’s.
