“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 ignition
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 minutes; 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 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. 60)
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 position auto-
matically 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 removed up or down with-
out it clicking (unstable position). When re-
leased, the lever will return to its home po-
sition.

INEFFICIENT ABS
SYSTEM (where
provided) (amber)
Turning the ignition key to MARthe warn-
ing light turns on, but it should go off after
few seconds.
The warning light turns on (together with
message + symbol on the display) when the
system is inefficient. In this case the brak-
ing system keeps its effectiveness un-
changed, but without the potential offered
by the ABS system.
Caution is advisable, particularly in all cas-
es of less than perfect grip. It is necessary
to contact Alfa Romeo Authorized Services
as soon as possible.

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 with the utmost care to the nearest
Alfa Romeo Authorized Service to have the
system checked.

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.
HAND BRAKE (fig. 115)
The hand brake lever is located between
the two front seats.
To operate the brake when the car is sta-
tionary, pull lever (A) upwards, until the re-
quired braking action is obtained.
When the ignition key is at MAR, the
warning light on the instrument cluster

If the car is on the move, the request is
not accepted; wait for the car to stop and
then request reverse gear engagement
again.
IMPORTANTOnce a gear has been
changed it is necessary to immediately re-
lease the gearshift control lever after mak-
ing the request. A manoeuvre prolonged
(over 10 seconds) makes the system au-
tomatically switch to CITYmode; every-
thing stops releasing the gearshift lever.
IMPORTANTIf wanting to leave the car
parked on a sloping road with a gear en-
gaged to keep it braked, it is necessary to
check that the display shows the new gear
engaged and then wait for 1 to 2 seconds
before releasing the brake pedal to allow
complete clutch engagement.

OPERATION WITH ENGINE OFF
IMPORTANTBefore using the gearshift
control lever, always check the gear en-
gaged on the display (N,1,2,3,4,5,
R).
With the engine off and the car station-
ary it is possible to engage all the gears.
With the car stationary and with the brake
pedal pressed, requests to shift gears are
both accepted through the control lever on
the central console or through the steering
wheel levers.
To request gearshifting, in addition to keep-
ing the brake pedal pressed:
– to shift upwards (+) (fig. 121) push
the lever “forwards” (if the car is in first gear
it shifts to second, if in second it shifts to
third and so on up to fifth). If the system
is in neutral (N) or reverse (R) moving thelever forwards causes the engagement of
first gear (1).
– to shift downwards (–) (fig. 121)
push the lever backwards (if the car is in
fifth gear it shifts to fourth, if in fourth it
shifts to third and so on down to first gear).
To allow setting the transmission to neu-
tral (N), starting from the condition with
the car stationary and brake pedal pressed,
move the gearshift lever to the right (fig.
122).
From any gear (N,1,2,3,4,5) and
with the car practically at a standstill, it is
possible to request engagement of reverse
gear, pushing the lever to the right and then
backwards (fig. 123).

SEMIAUTOMATIC OPERATION
(MANUAL)
In the MANUALoperating 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. 124);
– the buttons on the steering wheel (fig.
125), 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. 126) is pressed
again, thereby cutting out the previously se-
lected 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 new gear
ratio engaged.
When downshifting, the engine is accel-
erated automatically to bring it to the speed
necessary with the new gear ratio.
Neutral (N) is accepted until the car speed
exceeds 40 km/h.
The reverse gear engagement command
(R) is accepted only if the car is station-
ary.

VDC SYSTEM
(Vehicle Dynamics Control)
(on request for versions/
markets where applicable)
The VDC is an electronic system that con-
trols car stability, intervening on the driving
torque and braking the wheels in a differ-
entiated 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 system in-
tervenes on the engine and on the brakes
producing a stabilising torque.
HOW THE VDC
SYSTEM WORKS
System is engaged automatically when the
car is started and cannot be switched off.
The basic components of the 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 system is the 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, detects the rotations
of the car around its own vertical axis. The
centrifugal forces generated when the car
is cornering are detected by a highly sensi-
tive lateral acceleration sensor. 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.
System helps the driver to keep the car un-
der control in the event of a loss of tyre grip.
The forces induced by the system to con-
trol the loss of car stability always depend
on the grip between the tyre and the road
surface.

GETTING TO KNOW YOUR CAR
137
The stabilising action of the 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 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 system is indicated by
the flashing of the áwarning light on the
instrument cluster, to inform the driver that
the car is in critical conditions of stability and
grip.
VDC system failure warning
In the event of a failure the system dis-
engages automatically and the
áwarning
light on the instrument cluster turns on glow-
ing steadily, together with the message on
the reconfigurable multifunction display.
In the event of an system failure the car
behaves like a car not fitted with this sys-
tem: in any case it is advisable to contact
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 ASR can be switched
off and on again pressing switch (A-fig.
151).
When the function is turned off, the in-
strument panel warning light
Vturns on.
If the function is switched off when trav-
elling, it will turn on again automatically the
next time the engine is started.
fig. 151
A0A1107b
ASR SYSTEM
(Antislip Regulation)
(on request for versions/
markets where applicable)
The ASR function controls the car drive 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 safety.
– acceleration on slippery, snowy or frozen
surfaces.
– in the case of loss of grip on a wet sur-
face (aquaplaning).

CORRECT USE OF THE CAR
177
It is necessary therefore to limit their use
to the purposes for which they are certified.
IMPORTANTWhen winter tyres are
used with a maximum speed index below
the one that can be reached by the car (in-
creased by 5%), place a notice in the pas-
senger’s compartment, plainly in the driver’s
view, which states the maximum permissi-
ble speed of the winter tyres (as per EC Di-
rective).
Fit the same type of tyre on all four wheels
(brand and profile) to ensure higher driving
safety when braking and good handling.
Remember that it is inappropriate to
change the direction of rotation of tyres.WINTER TYRES
These tyres are specially designed for dri-
ving on snow and ice, to be fitted in re-
placement of those fitted on the car.
Use winter tyres of the same size as nor-
mal tyres provided on the car.
Alfa Romeo Authorised Services will be
pleased to advise you on the choice of the
tyre most suited to the use the Customer in-
tends to make of it.
For the type of tyre to be used, inflation
pressures and specifications of winter tyres,
follow the instructions given in the “Tech-
nical Specifications” chapter.
The winter features of these tyres are re-
duced considerably when the tread depth
is below 4 mm. In this case, they should be
replaced.
Due to the winter features, under normal
conditions of use or long motorway jour-
neys, the performance of these tyres is low-
er than that of normal tyres.
SNOW CHAINS
Use of snow chains should be in compli-
ance with local regulations.
For 1.8 T. SPARK, 2.0 JTS and 1.9
JTD versions, tyre 195/60 R15 can be
fitted with chains (use snow chains with re-
duced size with max protrusion beyond the
tyre profile of 12 mm). Tyres 205/60 R15
- 205/55 R16 - 205/55 ZR16 - 215/45
R17 - 215/45 ZR17 - 225/40 ZR18 can-
not be fitted with snow chains.
For 3.2
V6version, only use spider type
chains on tyres 215/45 R17” and
215/45 ZR 17”. Tyres 225/45 ZR17 -
225/40 ZR18 cannot be fitted with snow
chains.
Lineaccessori Alfa Romeo provides SPIKES
SPIDER COMPACT chains (model: 17003
compact) with 9 spikes, 16 mm adjustable
length and 17 inch wheel cap adapter.
Snow chains should only be applied to the
drive wheels (front).
Before purchasing or using snow chains,
you are recommended to contact Alfa
Romeo Authorised Services.
Check the tensions of the chain after the
first few metres have been driven.
