“Follow me home” device
(fig. 61)
This function allows the illumination of
the space in front of the car for the length
of time set, and is activated with the igni-
tion key at STOPor removed, pulling the
left-hand lever towards the steering
wheel.
This function is activated pulling the lever
within 2 minutes from when the engine is
turned off. At each single movement of
the lever, the staying on of the dipped
beams and sidelights is extended by 30
seconds up to a maximum of 3.5 min-
utes; the lights switch off automatically
after the time set.
Each time the lever is operated, the
1
warning light on the cluster turns on. Flashing(fig. 59)
The headlights are flashed pulling the
lever towards the steering wheel (instable
position) 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. 60)
Regardless of the position of the knurled
ring, moving the lever to the stable posi-
tion 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 position auto-
matically and the indicators are switched
off when the steering wheel is straight-
ened.
IMPORTANTIf you wish to signal a
rapid change of direction involving only a
minimal movement of the steering wheel,
the lever can be removed up or down
without it clicking (unstable position).
When released, the lever will return to its
home position.

INEFFICIENT ABS SYSTEM (where fitted)
Turning the ignition key to MARthe warning light on the dial turns on, but it should go off after
approx. 4 seconds.
The warning light turns on (on some versions the message + symbol are shown on the recon-
figurable multifunction 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 advised, particularly in all cases of less than perfect grip. It is also necessary to contact Alfa
Romeo Authorised Services.
The car is fitted with electronic braking distributor (EBD). The turn-
ing on at the same time of the
xand>warning lights on the dial
(on some versions the message + symbol are shown on the reconfig-
urable 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. Driving extremely carefully, immedi-
ately contact Alfa Romeo Authorised Services to have the system checked.
The turning on only of the
>warning light (on some versions the
message + symbol are shown on the reconfigurable multifunction dis-
play) 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 antilock function. In these conditions, the effectiveness
of the EBD may also be reduced. 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 braking, to have the system checked.

To release the hand brake:
– slightly lift the lever (A) and press the
release button (B);
– keeping the button pressed lower the
lever, the warning light
xon the instru-
ment cluster will go out.
To prevent the car from moving acciden-
tally, keep the brake pedal pressed when
engaging the hand brake.
IMPORTANTThe hand brake lever (A)
is fitted with a safety device which prevents
the brake from being released when, with
the lever pulled, button (B) is pressed.
Therefore, to release the brake, in addition
to pressing button (B), it is also necessary
to pull lever (A) further upwards to release
the safety device, then lower the lever com-
pletely.
IMPORTANTOn certain versions a
buzzer sounds to alert the driver if the car
is moved with the hand brake engaged.
GEARSHIFT LEVER (fig. 118)
The position of the single gears is shown
by the pictogram on the gearshift lever
knob.
When shifting gear, always fully depress
the clutch pedal. Before engaging reverse
gear (R) wait for the car to be stationary.
Certain versions are fitted with 6-gear gear-
box.
IMPORTANTReverse gear may only be
engaged with the car completely at a stand-
still. With the engine running, before en-
gaging reverse gear it is necessary to wait
for at least 3 seconds with the clutch pedal
fully depressed to prevent clashing and the
possibility of damaging the gears. The wheels should be
locked after a few clicks of
the hand brake. If it does
not occur contact Alfa Romeo Au-
thorised Services to have the hand
brake adjusted.To change gear smoothly,
the clutch pedal must be
fully depressed. Therefore,
there should be no obstacles on the
floor under the pedal unit: make
sure that any mats are well laid
and do not interfere with the ped-
als.

SEMIAUTOMATIC OPERATION
(MANUAL)
In the MANUAL operating mode, the dis-
play 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. 126);
– the buttons on the steering wheel
(fig. 127), which can be operated only
when the car speed exceeds 0.5 km/h.
TheMANUALoperating mode is set
when, with the CITYmode selected, the
CITYbutton(A-fig. 128) 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 20 km/h.
The reverse gear engagement command
(R) is accepted only if the vehicle is sta-
tionary.

VDC SYSTEM
(Vehicle Dynamics Control)
(upon request for
versions/markets where
provided)
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 wheels;
– 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- The performance of the
system, in terms of active
safety should not induce
the driver to take pointless and un-
necessary risks. The style of dri-
ving must in any case always be
adapted to the conditions of the
road surface, visibility and traffic.
The responsibility for road safety
is always and in any case the dri-
ver’s.
The VDC system helps the driver to keep
the car under control in the event of a loss
of tyre grip.
The forces induced by the VDC system to
control the loss of vehicle stability always
depend on the grip between the tyre and
the road surface.

ed by a highly sensitive lateral acceleration
sensor.
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 each wheel. These signals
allow 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 is
able to know the position of the car instant
by instant and compares it with the course
the driver 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 VDC system considerably en-
hances 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.For the VDC system to
work correctly, the tyres
must be of the same brand
and type on all wheels, in perfect
conditions and above all of the
specified type, brand and size.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 an 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.During use of the compact
spare wheel, the VDC sys-
tem continues working. It
should be borne in mind that the
spare wheel is smaller than a nor-
mal tyre, therefore its grip is low-
er than that of the other tyres of
the car.

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. 153) on the centre console.
When the device is switched off this is
shown by the lighting up of the led on the
switch itself.
If the function is switched off when trav-
elling, it will turn on again automatically the
next time the engine is started.

ASR SYSTEM
(Antislip Regulation)
(upon request for
versions/markets where
provided)
The ASR function controls the vehicle dri-
ve and cuts in automatically every time one
or both driving wheels slip.
In slipping conditions, tow 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 performance of the
system in terms of active
safety should not induce
the driver to take pointless and un-
necessary risks. The style of dri-
ving must in any case be adapted
to the conditions of the road sur-
face, visibility and traffic. Road
surface is always the driver’s re-
sponsibility.
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).
