erate the direction indicator stalk to select the side (right or left).
AUTOMATIC LIGHTING CONTROL (AUTOLIGHT)
(Dusk sensor)
(for versions/markets, where provided)
This system consists of an infrared LED sensor combined with a rain
sensor installed on the windscreen. It can detect changes of light
intensity outside the car according to the light sensitivity setting
programmed in the set-up menu: the higher the sensitivity, the low-
er the amount of external light needed to switch the lights on.
Activation
The dusk sensor is activated by turning the A ring fig. 40 to 2A.
In this way the side lights and dipped beam headlights are both
switched on automatically according to the outside light level.
EXTERIOR LIGHTS
LEFT STALK fig. 40
The left stalk operates most of the external lights. The external
lights can only be switched on when the ignition key is at MAR.
The instrument panel and the various controls on the dashboard
will come on when the external lights are switched on.
DAY LIGHTS (DRL) “Daytime Running Lights”
With the ignition key turned to MAR and A ring fig.40 turned to
position
Othe day lights are turned on; the other lights remain off.
For day light functions, see the “Menu Items” paragraph in this
chapter. If the function is deactivated, no lights are switched on
when the A ring is turned to position

MAIN BEAM HEADLIGHTS
With A ring in position 2pull the stalk towards the steering wheel
(stable position). The warning light
1on the instrument panel
will come on. To turn the lights off, pull the stalk again towards
the steering wheel (dipped beam headlights will stay on). It is
not possible to switch on the main beam headlights in fixed mode
if the automatic lighting control system is active.
FLASHINGS
Pull the stalk towards the steering wheel (unstable position) re-
gardless of the position of A ring. The
1warning light will come
on in the instrument panel.
DIRECTION INDICATORS
Put the stalk in the stable position:
❍upward: activation of right direction indicator;
❍downward: activation of left direction indicator.
Lights
¥orÎwill flash on the instrument panel. The direction in-
dicators are switched off automatically when the steering wheel
is straightened.
“Lane change” function
If you want to signal that you are changing lane, hold the left stalk
in the unstable position for less than half a second. The direction
indicator on the selected side flashes five times and then switch-
es off automatically. IMPORTANT The sensor is unable to detect the presence of fog. Un-
der these circumstances, these lights are therefore turned on man-
ually.
When the lights are turned on by the sensor, the fog lights (for ver-
sions/markets, where provided) and the rear fog lights may be
turned on. When the lights are automatically switched off, the front
and rear fog lights (if activated) are also switched off. The next
time the lights are switched on automatically, the fog lights must
be reactivated manually (if required).
With the sensor active, it is possible to flash the headlights but
the main beam headlights cannot be switched on. If you need to
turn these lights on, turn A ring fig. 40 to position
2and turn
the dipped beam headlights on.
When the lights have been activated automatically and are then
switched off by the sensor, the dipped beam headlights are switched
off first, followed by the side lights a few seconds later.
If the sensor is activated but is malfunctioning, the side lights and
dipped beam headlights are switched on independently of the out-
side light level and the sensor fault is indicated on the instrument
panel display. It is also possible to deactivate the sensor and switch
on these light.

Move the stalk up (unstable position) to limit operation to the time
for which the stalk is held in this position. When released, the stalk
will return to its default position and the wiper will be automati-
cally stopped.WINDOW CLEANING
The right stalk controls windscreen wiper/washer and heated rear
windscreen wiper/washer operation.
WINDSCREEN WIPER/WASHER fig. 41
This only operates with the ignition turned to MAR. The ring nut A
can have the following positions::
Owindscreen wiper off;
≤intermittent operation (low speed);
AUTO rain sensor activation (for versions/markets, where pro-
vided) (the windscreen wiper speed is automatically adapt-
ed to the intensity of the rain)
nintermittent operation;
≥slow operation;
¥fast operation.
fig. 41A0K0097m
Do not use the windscreen wipers to remove lay-
ers of snow or ice from the windscreen. In such con-
ditions, the windscreen wipers may be subjected to
excessive stress, prompting intervention from the motor
protection which prevents operation for a few seconds. If
operation is not restored, even after turning the key and
restarting the engine, contact Alfa Romeo Authorized Ser-
vices.
Do not operate the windscreen wiper with the
blades lifted from the windscreen.
“Smart washing” function
Pull the stalk towards the steering wheel (unstable position) to op-
erate the windscreen washer jet. Keep the stalk pulled for more
than half a second, with just one movement, to operate windscreen
washer/wiper jet at the same time.
The wiper stops working three strokes after the stalk is released.
A further stroke after approximately six seconds completes the wip-
ing cycle.

CONTENTS
If the engine is switched off with the stalk in the automatic posi-
tion, no wiping cycle will take place when the engine is started
again even if it is raining. This prevents accidental activation of the
rain sensor when the engine is started (i.e. when the windscreen
is being washed by hand or the wipers are stuck to the windscreen
by ice).
To restore automatic operation of the rain sensor, turn the ring on
the right A stalk fig. 41 from automatic position (AUTO) to
Opo-
sition and then turn A ring back to the AUTO position.
When the rain sensor is reactivated using any of the manoeuvres
described above, reactivation is indicated by a single stroke of
the windscreen wipers, regardless of the condition of the wind-
screen. If the sensitivity of the rain sensor is adjusted whilst it is
in operation, a single stroke of the windscreen wiper takes place
to confirm the changed setting.
In the event of the malfunction of the rain sensor whilst it is ac-
tive, the windscreen wiper operates intermittently at a speed con-
sistent with the sensitivity setting of the rain sensor, regardless of
whether it is raining or not (the sensor fault is indicated on the
instrument panel display). The sensor continues to operate and it
is possible to set the windscreen wiper to continuous mode (1
stor
2ndspeed). The fault indication remains for as long as the sensor
is active.
RAIN SENSOR fig. 42
(for versions/markets, where provided)
This is an infrared LED sensor fitted on the windscreen. It can de-
tect the presence of rain and consequently manage windscreen wip-
ing in accordance with the amount of water on the windscreen.
Activation
The sensor is activated by turning the A ring fig. 41 to the
“automatic” position (“AUTO”): the frequency of the windscreen
wiper strokes is automatically adjusted depending on the amount
of water on the windscreen. This frequency can vary from no stroke
(no rain - windscreen dry) up to the 2
ndconstant speed operation
(heavy rain - windscreen wet).
The sensitivity of the rain sensor can be adjusted through the Set
Up menu (see “Display” paragraph in this chapter).

SAFETY FUNCTIONS
When the engine is stopped by the Start&Stop system, if the dri-
ver releases his/her seat belt and opens the driver’s or passenger’s
door, the engine can be restarted only using the ignition key.
This condition is indicated to the driver by means of a buzzer and
by the symbol
Ublinking on the display (with a message, for
versions/markets, where provided).
ENERGY SAVING FUNCTION
(for versions/markets, where provided)
If, as a result of the engine automatic restarting, the driver does not
carry out any action on the vehicle for over 3 minutes, the Start&Stop
system stops the engine once and for all, to prevent fuel consump-
tion. In these cases, the engine can be restarted only using the ig-
nition key.
NOTEIn any case, it is possible to keep the engine running by de-
activating the Start&Stop system.
IRREGULAR OPERATION
In the event of malfunction, the Start&Stop system is deactivated.
The driver is informed of the fault by the flashing
Usymbol (ver-
sions with multifunction display) or
jsymbol (versions with re-
configurable multifunction display). For versions/markets, where
provided, a message is also displayed. In this case, contact
Alfa Romeo Authorized Services.
STORING THE CAR
In the case of storage, special care must be taken to disconnect the
battery electrical power supply.
Proceed as follows: detach the connector A-fig. 83 (by pressing but-
ton B) from sensor C for monitoring the status of the battery in-
stalled on the battery negative pole D. This sensor should never
be disconnected from the pole except if the battery is replaced.
fig. 83A0K0179m
In case of battery replacement, always contact
Alfa Romeo Authorized Services. Replace the bat-
tery using a new one of the same type (HEAVY
DUTY) and having the same specifications.

RADIO TRANSMITTERS AND CELLULAR PHONES
Radio transmitting equipment (vehicle mobile phones, CB radios,
amateur radio etc.) shall not be used inside the car unless a sep-
arate aerial is mounted on the roof.
IMPORTANT The use of these devices inside the passenger com-
partment (without a separate aerial) may cause the vehicle elec-
trical systems to malfunction. This could compromise safety in ad-
dition to constituting a potential hazard for passengers’ health.
In addition, transmission and reception of these devices may be af-
fected by the shielding effect of the car body. As far as the use of
EC-approved mobile phones is concerned (GSM, GPRS, UMTS), fol-
low the instructions for use provided by the mobile phone manu-
facturer.
PARKING SENSORS
(for versions/markets, where provided)
The parking sensors are located on the rear bumper fig. 88 and
their function is to inform the driver, through an intermittent beep-
ing, of the presence of obstacles behind the car.
TURNING THE SENSORS ON
The sensors are turned on when reverse gear is engaged. As the
distance from the obstacle behind the car decreases, the beeping
becomes more frequent.

DISPLAY INDICATIONS
(for versions/markets, where provided)
When the sensor is activated, the "Reconfigurable multifunctional
display" (for versions/markets where provided) shows the screen
illustrated in fig. 88a; the information about the presence of and
distance from the obstacle is given by the buzzer and also by a
visual indication on the instrument panel display. If there are se-
veral obstacles, the closest one is indicated.
BUZZER WARNINGS
When reverse gear is engaged a buzzer warning is automatically
activated if there is an obstacle within the range of operation.
The acoustic signal:
❍increases as the distance between the car and the obstacle de-
creases;
❍becomes continuous when the distance between the car and
the obstacle is less that 30 cm and stops immediately if the
distance increases;
❍remains constant if the distance between the vehicle and the
obstacle remains unchanged, whilst if this situation occurs for
the side sensors, the signal is interrupted after about 3 seconds,
for example, to prevent signals in the case of manoeuvres along-
side walls.
IMPORTANT The volume of the audible signal can be adjusted th-
rough the option "Warnings volume" of the "Set-Up menu".
OPERATION WITH TRAILER
Parking sensor operation is automatically turned off when the trail-
er electric cable plug is fitted into the car tow hook socket. The sen-
sors are automatically enabled again when the trailer cable plug
is removed.
The sensor must be free of mud, dirt, snow or ice
in order for the system to work. Be careful not to
scratch or damage the sensors while cleaning them.
Avoid using dry, rough or hard cloths. The sensors should
be washed using clean water with the addition of car sham-
poo if necessary. In washing stations, clean sensors quick-
ly keeping the vapour jet/high pressure washing noz-
zles at a distance of at least 10 cm from the sensors.

CONTENTS
The ultimate responsibility when parking and car-
rying out other dangerous manoeuvres still rests
with the driver. When carrying out such manoeu-
vres, always ensure that the manoeuvring area is free
of people (particularly children) and animals. Parking sen-
sors are designed to assist drivers; however, you must al-
ways concentrate fully during potentially dangerous ma-
noeuvres, even if carried out at low speeds.
GENERAL WARNINGS
During parking manoeuvres, pay the utmost attention to any ob-
stacles that could be located above or below the sensors.
Sometimes, objects located close to the rear part of the car may
not be detected by the system and may damage the car or become
damaged themselves.
Here below are some conditions that may influence the perfor-
mance of the parking system:
❍Reduced sensor sensitivity and a reduction in the parking as-
sistance system performance could be due to the presence on
the surface of the sensor of: ice, snow, mud, thick paint.
❍the sensor may detect a non-existent obstacle (echo noise) due
to mechanical noises, for example when washing the vehicle,
in case of rain, strong wind, hail.
❍the signals sent by the sensors can also be altered by the pres-
ence of ultrasound devices (e.g. pneumatic brake systems or
pneumatic drills) near the car;
❍sensor performance can also be influenced by the position of
the sensors. For example by a change in the ride setting (caused
by the wear of the shock absorbers, suspension), overloading
the car and carrying out specific tuning operations that require
the car to be lowered;
❍the detection of obstacles at the top part of the vehicle may
not be guaranteed because the system detects obstacles that
could cause an impact with the vehicle in the bottom part.
For repainting the bumpers or retouching the paint-
work around the sensors contact Alfa Romeo
Authorized Services. Incorrect application of paint
may compromise the operation of the parking sensors.
