Flashing(fig. 56)
The headlights are flashed pulling the lever
towards the steering wheel (instable posi-
tion) regardless of the position of the
knurled ring. The
1warning light on the
cluster will come on at the same time.
IMPORTANTOnly the main-beam lights
are flashed. To avoid penalties follow local
regulations.
Direction indicators (fig. 57)
Regardless of the position of the knurled
ring, moving the lever to the stable position
will:
up, position (1) - engage the right-hand
direction indicators;
down, position (2) - engage the left-hand
direction indicators.One of the warning lights (
RorE) will
come on on the instrument cluster at the
same time.
The lever is returned to its home position
automatically and the indicators are
switched off when the steering wheel is
straightened.
IMPORTANTIf you wish to signal a
rapid change of direction involving only a
minimal movement of the steering wheel,
the lever can be moved up or down without
it clicking (unstable position). When re-
leased, the lever will return to its home po-
sition. When low beams and fog lights turned
on, the external light control unit (integral
into the Body Computer) can behave ac-
cording to one of the following logic:
– as the high beams are turned on, the
low beams turn off, in the meanwhile the
fog lights remain on, and the starting con-
ditions are restored, as soon as the low
beams are turned on again;
– otherwise, when the high beams are
turned on, the fog lights are turned off, and
they will automatically be turned on again
when the high beams are turned off.
Hence, should the Body Computer be re-
placed, the lights management logic could
differ from the previous one.

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.

INEFFICIENT ABS SYSTEM
Turning the ignition key to MARthe warning light on the dial lights up, but it should go off after
approx. 4 seconds.
The warning light turns on together with the message + symbol on the reconfigurable multifunc-
tion display, when the system is inefficient. In this case the braking system keeps its effectiveness
unchanged, but without the potential offered by the ABS system. Caution is advisable, particularly
in all cases of less than perfect grip. It is therefore necessary to contact Alfa Romeo Authorised Ser-
vices as soon as possible.
Inefficient EBD electronic braking distributor
x
>
+The car is fitted with electronic braking distributor (EBD). The turning
on at the same time of the xand>warning lights on the dial togeth-
er with the message + symbol on the reconfigurable multifunction display, with
the engine running indicates an EBD system failure; in this case heavy braking
may cause the rear wheels to lock before time, with the possibility of skidding.
Drive extremely carefully to the nearest Alfa Romeo Authorised Service to have
the system checked.
WARNING
The turning on only of the >warning light on the dial together with
the message + symbol on the reconfigurable multifunction display, with
the engine running normally indicates a failure of the ABS system only. In this
case the braking system maintains its effectiveness, without however the an-
tilock function. In these conditions, the effectiveness of the EBD may also be re-
duced, In this case too, you are recommended to contact the nearest Alfa Romeo
Authorised Service immediately, driving in such a way as to avoid sharp brak-
ing, to have the system checked.

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.
WARNING

GETTING TO KNOW YOUR CAR
137
The stabilising action of the VDC system is
based on the calculations of the system elec-
tronic control unit, which processes the sig-
nals received from the steering wheel rota-
tion sensor, acceleration sensor and rotation
speed sensor of ech wheel.These signals al-
low the control unit to recognise the ma-
noeuvre the driver intends to do when the
steering wheel is turned.
The control unit processes the information
received from the sensors and therefore able
to know the position of the car instant by in-
stant and compare it with the course the dri-
ver would like to follow. In the event of a
discrepancy, in a fraction of a second the
control unit chooses and commands the
most suitable intervention to bring the car
immediately back to the required course:
braking one or more wheels at different in-
tensity and, if necessary, reducing the pow-
er transmitted by the engine.
The corrective actions are modified and
controlled continuously in seeking the course
required by the driver.
The action of the VDC system considerably
enhances the active safety of the car in very
critical situations and it is particularly help-
ful when the grip conditions of the road sur-
face change.CUTTING IN
OF THE VDC SYSTEM
The cutting in of the VDC system is indi-
cated by the flashing of the
áwarning light
on the instrument cluster, to inform the dri-
ver that the car is in critical conditions of sta-
bility and grip.
VDC system failure warning
In the event of a failure the VDC system
disengages automatically and the
áwarn-
ing light on the instrument cluster turns on
glowing steadily, together with the message
on the reconfigurable multifunction display.
In the event of a VDC system failure the
car behaves like a vehicle not fitted with this
system: in any case it is advisable to con-
tact Alfa Romeo Authorised Services as soon
as possible.
For the VDC system to
work correctly, the tyres
must be of the same brand and
type on all wheels, in perfect con-
ditions and above all of the speci-
fied type, brand and size.

SWITCHING ON
THE ASR FUNCTION
The ASR function switches on automati-
cally each time the engine is started.
When travelling the device can be switched
off and on again pressing switch (A-
fig. 136) on the centre console.
Function disconnection is shown by the rel-
evant led on the switch itself being turned
on and by the dedicated message displayed
on the re-configurable multifunction display.
Should the function be disconnected when
running, it will automatically be activated
again at the next ignition and the re-con-
figurable multifunction display will inform
user about this condition by displaying a ded-
icated message.

ASR SYSTEM
(Antislip Regulation)
The ASR function controls the vehicle dri-
ve and cuts in automatically every time one
or both driving wheels slip.
In slipping conditions, two different control
systems are activated:
1) if slipping involves both driving wheels,
being caused by excessive power transmit-
ted, the ASR device cuts in reducing the pow-
er transmitted by the engine.
2) if slipping involves only one driving
wheel, the ASR system cuts in automatical-
ly braking the wheel that is slipping, with
an effect similar to that of a self-locking dif-
ferential.
The action of the ASR is particularly help-
ful in the following circumstances:
– slipping of the inner wheel on a bend,
due to the effect of dynamic load changes
or excessive acceleration.
– too much power transmitted to the
wheels also in relation to the conditions of
the road surface.
– acceleration on slippery, snowy or frozen
surfaces.
– in the case of loss of grip on a wet sur-
face (aquaplaning).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 be adapted to the condi-
tions of the road surface, visibili-
ty and traffic. Road safety is al-
ways the driver’s responsibility.

CORRECT USE OF THE CAR
179
– Do not drive for long periods without a
break. During breaks get out of the vehicle
and move around a bit to shake off the
drowsiness.
– Make sure the air in the passenger com-
partment is changed constantly.
– Never coast the vehicle downhill with
the engine switched off: this eliminates the
engine braking and power steering effect
thus requiring a greater effort on the pedal
and steering wheel.
NIGHT DRIVING
Here are some suggestions for night dri-
ving.
– Drive with particular care: night driving
involves a greater degree of concentration.
– Reduce speed, especially on unlit roads.
– At the first signs of drowsiness stop the
car: continuing the journey is dangerous for
yourself and others. Continue driving only
after sufficient rest.
– Maintain a greater distance from the ve-
hicle in front than in the day: it is more dif-
ficult to judge the speed of a vehicle when
only the lights can be seen.
– Ensure that the headlights are correctly
aimed: if they are too low, visibility is re-
duced and eyesight is tired. If they are too
high they may cause disturbance to other
road users.
– Use the main beams only outside built-
up areas and only when you are certain that
other drivers are not disturbed by their use.
– When meeting oncoming vehicles,
switch off the main beams and drive with
the dipped-beam headlights on.
– Keep the headlights and light units
clean.
– Outside built-up areas take care of ani-
mal crossings.Always fasten the front and
rear seat belts including
those of any children’s seat. Trav-
elling without seat belts increases
the risks of serious injury or even
death in the event of an accident.
WARNING
Take car when fitting addi-
tional spoilers, alloy wheels
and wheel caps: they might reduce
ventilation of the brakes, thus their
efficiency, during abrupt and re-
peated braking, or long downhill
slopes.
WARNING
Never drive with objects
on the floor in front of the
driver’s seat: they might get stuck
under the pedals making it impos-
sible to accelerate or brake.
WARNING
Make sure any mats are
appropriate in size: even a
slight inconvenience to the braking
system may require a higher ped-
al stroke than normal.
WARNING
Water, ice and salt on the
roads may deposit on the
brake disks, reducing the effec-
tiveness of the brakes the first
time they are used.
WARNING
