“INTELLIGENT WASHING” FUNCTION
Pulling the lever towards the steering
wheel (fig. 76) (unstable position) oper-
ates the windscreen washer.
Keeping the lever pulled, with only one
movement it is possible to operate the
washer jet and the wiper at the same time;
indeed, 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.Rain sensor
(for versions/markets where
applicable) (fig. 77)
The rain sensor (A), fitted only on cer-
tain versions, is an electronic device com-
bine with the windscreen wiper which has
the purpose of automatically adjusting the
number of wipes during intermittent opera-
tion, to 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. 74) 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.Turn ring (F-fig. 75) to set the rain sen-
sor sensitivity level:
■■
= low sensitivity
■■■
= medium ensitivity
■■■■
= high sensitivity.
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 (MAR position) 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).

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.

TO INCREASE THE MEMORISED
SPEEDThe speed memorised can be increased
in two ways:
1)pressing the accelerator and then mem-
orising the new speed reached (turning the
ring (B) for more than three seconds);
or
2)momentaneously turning the ring (B)
to (+): each pulse of the ring will correspond
to a slight increase in speed (about 1.5
km/h) while pressing continuously will cor-
respond to a continuous speed increase. Re-
leasing the ring (B) the new speed will be
memorised automatically.TO REDUCE THE MEMORISED
SPEEDThe speed memorised can be reduced in
two ways:
1)disengaging the device (for instance
pressing the brake pedal) and then memo-
rising the new speed (turning the ring (B)
to (+) for at least three seconds);
2)keeping the ring pressed (B) at (–)
until reaching the new speed which will be
memorised automatically.
RESETTING THE MEMORISED
SPEEDThe memorised speed is automatically re-
set turning off the engine or moving the ring
(A) to OFF.
When travelling with the
cruise control on, do not
move the gearshift lever to neutral.
WARNING
The cruise control may only
be engaged at speeds be-
tween 30 and 190 km/h.
WARNING
It is advisable to engage
the cruise control only
when the conditions of the traffic
or road so permit under completely
safe conditions: i.e.: straight and
dry roads, dual carriageways or
motorways, flowing traffic and
smooth road surface. Do not en-
gage the device in town or in
heavy traffic conditions.
WARNING
If the device is faulty or
not working, turn the ring
(A) to OFF and contact Alfa Romeo
Authorized Services after checking
that the protection fuse is intact.
