INTERIOR LIGHTS
FRONT CEILING LIGHT
Switch 5 fig. 21 is used to switch on/off
roof lights.
Switch 5 positions:
central position: lights 1 and 4 switch
on/off when the doors are
opened/closed;
pressed to the left(position OFF):
lights 1 and 4 are always switched off;
pressed to the right(position):
lights 1 and 4 are always switched on.
Lights switch on/off progressively.
Switch 2 switches on/off light 1.
Switch 3 switches on/off light 4.
IMPORTANT Before getting out of the
car, make sure that both switches are in
the central position: when the doors are
closed the lights will switch off to avoid
draining the battery.
In any case, if the switch is left in the on
position, the roof light switches off
automatically about 15 minutes after the
engine has been switched off.
ROOF LIGHT TIMING

GETTING TO KNOW YOUR CAR

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 windscreen
wiper will be automatically stopped.
“Smart washing” function
Pull the stalk 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 windscreen wiper stops working
three strokes after the stalk is released.
A further stroke after approx. 6 seconds
completes the wiping cycle.
RAIN SENSOR
(for versions/markets, where provided)
It can detect the presence of rain and
consequently manage windscreen wiping
in accordance with the amount of water
on the windscreen.
The sensor is activated when the ring 2
fig. 22 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.
If no rain is detected, the wiper will not
carry out any strokes.If the engine is switched off with the
lever in the automatic position, when the
car is next started, no wiping cycle will
take place even if it is raining. This is to
prevent unwanted activation of the rain
sensor when the engine is started (i.e.
when the windscreen is being washed by
hand or the wiper blades are stuck to the
windscreen by ice).
To restore automatic operation of the
rain sensor, turn the ring on the right stalk
2 fig. 22 from automatic position (AUTO)
to positionOand then turn ring 2 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.
REAR WINDOW WIPER/WASHER
(for versions/markets, where provided)
This operates only with the ignition key
turned to MAR.
Turn ring 1 fig. 22 from positionOto
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.
Pushing the stalk towards the dashboard
(rocking 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.
IMPORTANT
5)Never use the windscreen wipers 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.
6)Do not operate the windscreen wiper with
the blades lifted from the windscreen.

33)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce the
pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on the
current road conditions.
34)To obtain the maximum efficiency of the
braking system, a bedding-in period of about
500 km is needed: during this period it is
better to avoid sharp, repeated and
prolonged braking.
35)If the ABS intervenes, this indicates that
the grip of the tyres on the road is nearing its
limit: you must slow down to a speed
compatible with the available grip.
36)The ABS cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
37)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
38)The capability of the ABS must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
39)For the correct operation of the ABS, the
tyres must of necessity be the same make
and type on all wheels, in perfect condition
and, above all, of the prescribed type and
dimensions.
40)The ASR cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
41)The ASR system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.42)The capability of the ASR must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
43)The HBA system can’t overrule the
natural laws of physics, and can’t increase
the grip available according to the condition
of the road.
44)The HBA system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
45)The features of the HBA system must
never be tested in imprudent or dangerous
ways, with the possibility of putting the
safety of the driver, occupants or other road
users at risk.
46)DST is an aid for driving and does not
relieve the driver of responsibility for driving
the vehicle.iTPMS System (indirect Tyre
Pressure Monitoring System)
(for versions/markets, where provided)
DESCRIPTION
The car can be equipped with the iTPMS
(indirect Tyre Pressure Monitoring
System) which monitors the tyre inflation
status thanks to wheel speed sensors.
The system warns the driver if one or
more tyres are flat by the dedicated
warning light
continuously on and a
warning message on the display.
If one tyre only is flat, the system can
indicate its position: it is in any case
recommended to check the pressure on
all four tyres.
This indication is displayed also when
turning the engine off and on again until
the RESET procedure is carried out.
RESET PROCEDURE
The iTPMS needs an initial "self-learning"
phase (with length depending on the
driving style and road conditions: optimal
conditions being driving on a straight
road at 80 km/h for at least 20 minutes)
which starts when the RESET procedure
is carried out.
The Reset procedure must be carried out:
each time tyre pressure is modified;
when even only one tyre is changed;
when tyres are rotated/inverted;

SAFETY

Let’s get to the core of the vehicle: seeing how you can exploit all
of its potential to the full.
We’ll look at how to drive it safely in any situation, so that it can be
a welcome companion, with our comfort and our wallets in mind.
