AUTOMATIC LIGHTING
CONTROL (AUTOLIGHT)
(Dusk sensor)
(for versions/markets, where provided)
This infrared LED sensor, combined
with the rain sensor and located on the
windscreen, detects the variations in
outside brightness depending on the
light sensitivity set with the Setup
Menu: the greater the sensitivity, the
less external light is required to activate
the external lights.Activation
The dusk sensor activates when ring
nut A fig. 31 is turned to
. In this
way the side lights and dipped beam
headlights are activated automatically
according to the external lighting
conditions.
IMPORTANT The sensor is unable to
detect the presence of fog. Therefore
under these circumstances, these lights
must be turned on manually.
When the lights are turned on by the
sensor, the fog lights (for versions/
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. To
activate these lights, turn the ring nut A
to
and activate the fixed dipped
beam headlights.

GETTING TO KNOW YOUR CAR

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 irrespective of the outside light
level and the sensor failure is indicated
on the display.
It is also possible to deactivate the
sensor and switch on the side lights
and dipped beam headlights.MAIN BEAM HEADLIGHTS
To activate the main beam headlights,
with ring nut A fig. 31 at
, pull the
stalk towards the steering wheel
beyond the end of travel position. The
warning light switches on in the
instrument panel.
When the stalk is pulled towards the
steering wheel again, beyond the end
of travel position, the main beam
headlights deactivate, the dipped beam
headlights reactivate and thewarning light switches off.
It is not possible to switch on the main
beam headlights constantly if automatic
light control is active.
FLASHING
To do this, pull the stalk towards the
steering wheel (unstable position)
regardless of the position of ring nut A
fig. 31. The
warning light switches
on in the instrument panel.
REAR FOG LIGHTS
For the activation and deactivation of
the rear fog lights, refer to the
"Controls" section.DIRECTION INDICATORS
Bring the stalk to the (stable) position:
❒upwards: activates right direction

WINDOW CLEANING
IN BRIEF
The right stalk controls screen
wiper/washer operation.
This operates only with the ignition
key turned to MAR.
WINDSCREEN
WASHER/WIPER
Operation
13) 14)
Ring nut A fig. 32 has the following
positions:Owindscreen wipers off;
intermittent operation (low
speed);
AUTO
rain sensor activation (for
versions/markets, where
provided) (the windscreen wipers
adapt the operating speed
automatically to suit the intensity
of the rain)intermittent operation;continuous slow operation;continuous fast operation.
Move the stalk upwards (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 automatically stopped.
"Smart washing"
function
Pull the lever towards the steering
wheel (unstable position) to operate the
windscreen washer. Keep the stalk
pulled for more than half a second to
operate the windscreen washer jet and
wiper automatically with a single
movement.
The wiper stops working three strokes
after the stalk is released. A further
stroke after approximately 6 seconds
completes the cycle.RAIN SENSOR
(for versions/markets, where provided)
This is an infrared LED sensor fitted
on the car windscreen fig. 33.
It is able to detect the presence of rain
and consequently manage windscreen
wiping in accordance with the amount
of water on the windscreen.
Activation
The sensor is activated when ring nut A
fig. 32 is turned to “automatic” position
(“AUTO” control): the windscreen wiper
stroke frequency is thus adjusted in
accordance with the amount of water
on the windscreen.
This frequency can vary from no stroke
(no rain - windscreen dry) up to the
2
nd
constant speed operation (heavy
rain - windscreen wet).

The sensitivity of the rain sensor can be
adjusted through the Setup menu
(see paragraph “Menu Items” in the
“Knowing the instrument panel”
section).
If the engine is stopped with the lever in
“automatic” position, when it is next
started no wiping cycle will take place
even if it is raining. This prevents
accidental activation of the rain sensor
when the engine is started (e.g. when
the windscreen is being washed by
hand or the wipers are stuck to the
windscreen when there is ice).
To restore automatic operation of the
rain sensor, turn the ring nut on the
right stalk A fig. 32 from automatic
position (AUTO) toOposition and then
turn A ring nut 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
windscreen.
If the sensitivity is changed whilst the
rain sensor is operating, a windscreen
wiper stroke is carried out to confirm
the change.In the event of malfunction of the rain
sensor whilst it is active, the
windscreen wiper operates
intermittently at a speed consistent with
the sensitivity setting of the rain sensor,
regardless of whether there is rain on
the glass (sensor failure is indicated on
the display).
The sensor continues to operate and it
is possible to set the windscreen wiper
to continuous mode (1
stor 2
nd
speed).
The failure indication remains for as
long as the sensor is active.
REAR WINDOW
WASHER/WIPER
(for versions/markets, where provided)
Activation
This operates only with the ignition key
turned to MAR.
Turn ring nut B fig. 32 from positionO
to position
to operate the rear
window wiper as follows:
❒in intermittent mode when the
windscreen wiper is not operating;
❒in synchronous mode (at half the
speed of the windscreen wiper) when
the windscreen wiper is operating;
❒in continuous mode with reverse gear
engaged and the control active.With reverse gear engaged and
windscreen wiper on, the rear window
wiper is activated in continuous mode.
Pushing the stalk towards the
dashboard (unstable position) will
activate the rear window washer jet.
Keep the stalk pushed for more than
half a second to activate the rear
window wiper as well. Releasing the
stalk will activate the smart washing
function, as described for the
windscreen wiper.
WARNING
13) Do not use the screen wiper to
remove layers of snow or ice
from the windscreen. In such
conditions, the windscreen wiper
may be subjected to excessive
stress and the motor cut-out
switch, which prevents operation
for a few seconds, may intervene.
If operation is not restored (even
after restarting that car with the
key), contact an Alfa Romeo
Dealership.
14) Do not operate the windscreen
wiper with the blades lifted from
the windscreen.

GETTING TO KNOW YOUR CAR

ESC SYSTEM
IN BRIEF
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by
the engine can also be reduced in
order to maintain control of the car.
30) 31) 32) 33) 34)
The ESC system uses sensors installed
on the car to determine the trajectory
that the driver intends to follow and
compares it with the car’s effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
car’s understeer or oversteer.
❒Oversteer: occurs when the car is
turning more than it should according
to the angle of the steering wheel.
❒Understeer: occurs when the car is
turning less than it should according
to the angle of the steering wheel.The ESC system also includes the
following systems:
❒EBD
❒ABS
❒CBC
❒ASR
❒HILL HOLDER
❒HBA
❒MSR
❒DST
❒“ELECTRONIC Q2” (“E-Q2”)
❒"PRE-FILL" (RAB - Ready Alert
Brake)
SYSTEM ACTIVATION
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
SYSTEM INTERVENTION
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.EBD SYSTEM
The EBD system is an integral part of
the ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear
wheels.
This guarantees greater braking stability
for the car, preventing sudden locking
of the rear wheels and the consequent
instability of the car.
ABS
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the car
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes when braking
and the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.
