EBD failure
EBD failure is indicated by the turning
on of warning lights
>+xon the in-
strument panel (on certain versions to-
gether with the dedicated message on
the display) (see section “Warning lights
and messages”).
In this case with sharp braking the rear
wheels might lock too early, with the
possibility of skidding. Drive extremely
carefully to the closest Alfa Romeo Au-
thorized Services to have the system
checked.
BRAKE ASSIST
(emergency braking
assistance)
The system, which cannot be cut out,
recognizes emergency braking (on the
ground of the brake pedal operation
speed) and considerably increases the
pressure in the brake circuit.
Brake Assist is deactivated on the ver-
sions equipped with VDC system in the
event of VDC system failure, indicated
by the turning on of warning light
áon
the instrument panel (on certain ver-
sions together with a message on the
display).
FAILURE WARNING LIGHTS
ABS failure
ABS failure is indicated by the turning
on of warning light
>on the instru-
ment panel (on certain versions together
with the dedicated message on the dis-
play) (see section “Warning lights and
messages”). In this case the braking
system is still efficient, though without
the aid of the ABS system.
Drive carefully to the closest Alfa Romeo
Authorized Services to have the system
checked.

VDC SYSTEM
(Vehicle Dynamics
Control)
(where provided)
The VDC system is an electronic system
controlling the car stability in the event
of tyre grip loss.
The VDC system is therefore particular-
ly useful when grip conditions of the
road surfaces changes.
VDC SYSTEM
INTERVENTION
It is signalled by the blinking of the
warning light
áon the instrument pan-
el, to inform the driver that the car is
in critical stability and grip conditions.
TURNING THE VDC SYSTEM
ON/OFF
The VDC system is automatically acti-
vated when the engine is started. When
travelling, to turn the VDC off press the
ASR/ VDC button on the central console
fig. 103for 2 seconds. Turning off the
VDC will also turn off the ASR. Both func-
tions can be reactivated by pressing the
ASR/VDC button.
VDC system deactivation is indicated
by the instrument panel warning light
á(on certain versions a symbol is dis-
played) and by the circular led around
the ASR/VDC button.
If the VDC has been turned off when
travelling, at next engine start-up it will
turn on again automatically.
FAILURE WARNING LIGHTS
In the event of failure, the VDC system
is automatically disconnected and the
warning light
ácomes on with fixed
light on the instrument panel (on cer-
tain versions together with a message
on the display) (see section “Warning
lights and messages”). In this case con-
tact Alfa Romeo Authorized Services as
soon as possible.

Failure warnings
In the event of malfunctioning, the ASR
system is automatically disconnected
and on versions fitted with “Reconfig-
urable multifunction display” symbol
Vis displayed. In this case contact Al-
fa Romeo Authorized Services as soon
as possible.

MSR system (engine braking
torque control)
It is an integral part of the ASR system
that in case of sudden gear shifting, cuts
in providing torque to the engine thus
preventing excessive driving wheel dri-
ve that, specially in poor grip conditions,
can lead to loss of stability.
For correct operation of
the ASR system, the
tyres must absolutely be of
the same brand and type on all
wheels, in normal conditions of
use, at the proper inflation
pressure values and, above all,
of type, brand and size speci-
fied (see paragraph “Wheels”
in section “Technical Specifica-
tions”).

EOBD SYSTEM
(optional for
versions/markets
where applicable)
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis
of the components of the car correlat-
ed with emissions.
It also alerts the driver, by turning on the
warning light
Uon the instrument pan-
el (on certain versions together with the
message on the display) (see section
“Warning lights and messages”), when
these conditions are no longer in peak
conditions.
If when fitting the key
into the ignition device,
the warning light
U
does not turn on or if, while
travelling it turns on glowing
steadily or flashing, contact Al-
fa Romeo Authorized Services
as soon as possible. Warning
light
Uoperation can be
checked by means of special
equipment by traffic agents. Al-
ways comply with the traffic
regulations in force in the coun-
try where you are travelling.
The objective is:
❒ to keep system efficiency under con-
trol;
❒ to warn when a fault causes emission
levels to increase;
❒to warn of the need to replace dete-
riorated components.
The system also has a diagnostic con-
nector that can be interfaced with ap-
propriate tools, which makes it possible
to read the error codes stored in the con-
trol unit, together with a series of spe-
cific parameters for engine operation
and diagnosis. This check can also be
carried out by the traffic police.
IMPORTANTAfter eliminating the in-
convenience, to check the system com-
pletely, Alfa Romeo Authorized Services
are obliged to run a bench test and, if
necessary, road tests which may also
call for a long journey.

SENSOR DETECTION
RANGE
Sensors enable the system to monitor
the front part (versions with 8 sensors)
and the rear part of the car.
Actually their position covers the central
and side areas of the front and rear part
of the car.
An obstacle positioned at central area is
detected at a distance less than 0.9 m
(front) and 1.40 m (rear).
An obstacle positioned at side area is de-
tected at a distance less than 0.6 m.
For proper operation,
the parking sensors shall
always be clean from
mud, dirt, snow or ice. When
cleaning the sensors, take the
utmost care to prevent their
damaging; do not use therefore
dry or rough clothes. Sensors
shall be washed with clean wa-
ter and car detergent, if re-
quired. In washing stations,
clean sensors quickly keeping
the vapour jet/high pressure
washing nozzles at 10 cm at
least from the sensors.
Repainting the bumpers
or touch-up in the sen-
sor area, if required,
shall be carried out at Alfa
Romeo Authorized Services on-
ly. Incorrect repainting may im-
pair regular operation of the
parking sensors.
INDICATIONS ON THE
DISPLAY (where provided)
On versions with 8 sensors, sensor acti-
vation is indicated on the “Reconfig-
urable multifunction display” (where pro-
vided) by screen fig.107; therefore ob-
stacle presence and distance is indicated
(in addition to buzzer) also on the in-
strument panel display.
In the event of several obstacles, the ob-
stacle closest to the car will be indicat-
ed.

If a failure is indicated, stop the car, turn
the engine off and then clean the sen-
sors. Make sure to be far from possible
ultrasound sources (e.g.: truck pneu-
matic brakes or pneumatic hammers).
If failure cause has been eliminated the
system will resume regular operation
and warning
tand the corresponding
warning message will turn off.
If the warning light stays on, contact Al-
fa Romeo Authorized Services to have
the system inspected, although the sys-
tem keeps on working. If the failure de-
tected does not impair system operation,
the system keeps on working and fail-
ure is stored in order to be then detect-
ed by Alfa Romeo Authorized Services
at next inspection.
GENERAL WARNINGS
When parking, take the utmost care to
obstacles that may be set above or un-
der the sensors. Objects set close to the
car front or rear part, under certain cir-
cumstances are not detected and could
therefore cause damages to the car or
be damaged.
Indications sent by the sensors can be
altered by dirt, snow or ice deposited on
the sensors or by ultrasound systems
(e.g.: truck pneumatic brakes or pneu-
matic hammers) set nearby the car.
TOWING TRAILERS
Rear sensors are reactivated automati-
cally when removing the trailer cable
plug.
FAILURE INDICATIONS
The system control unit checks every
system component each time the key is
fitted into the ignition device. Sensors
and relevant electrical connections are
then constantly monitored during sys-
tem operation.
Sensor failure is indicated by turning on
of warning light
t(where provided)
on the instrument panel (on certain ver-
sions together with the message on the
display) (see section “Warning lights
and messages”).
Rear sensors operation
is deactivated automat-
ically when the trailer
electric cable plug is fitted into
the car tow hook socket.

The car can be equipped with the
T.P.M.S. (Tyre Pressure Monitoring Sys-
tem). This system consists of a radio-fre-
quency sensor, installed on each wheel
(on the rim inside the tyre) that sends
pressure information to the control unit.IMPORTANT NOTES
Failure indications will not be stored and
therefore will not be displayed when
turning the engine off and on again. If
failure persists, the control unit will send
warning indications to the instrument
panel only after a few seconds when the
car is moving.
Tyre pressure should be checked with
tyres cold. Should it become necessary
for whatever reason to check pressure
with hot tyres, do not reduce pressure
although it is higher than the prescribed
value but repeat the check when tyres
are cold (see section “Wheels” in sec-
tion “Technical Specifications”).
TYRE PRESSURE MONITORING SYSTEM -
T.P.M.S. (where provided)
(optional for versions/
markets where applicable)
The T.P.M.S. does not
exempt the driver from
checking tyre pressure, includ-
ing the space-saver spare
wheel (where provided) at
regular intervals.
WARNING
T.P.M.S. cannot indicate sudden tyre
pressure drops (e.g.: tyre burst). In this
event, brake the car cautiously and
avoid sudden steering.
The T.P.M.S. system requires special
equipment. Consult Alfa Romeo Autho-
rized Services to know what type of ac-
cessories are compatible with the sys-
tem (wheels, wheel caps, etc.). Using
other accessories could cause system
malfunctioning. Due to inflation valve
special characteristics, use only tyre re-
pair sealants approved by Alfa Romeo;
other sealants could cause system mal-
functioning.

If after repairing a punctured tyre with
the Fix&Go automatic kit and restoring
the initial conditions the flat tyre warn-
ing light continues to stay on, contact
Alfa Romeo Authorized Services.
Tyre pressure could change according to
outside temperature. For this reason the
T.P.M.S. system could temporarily indi-
cate low tyre pressure. In this event
check pressure with cold tyres and re-
store proper inflation values if required. If the car is fitted with T.P.M.S. system,
when changing a tyre, change also the
rubber seal of the valve and the fas-
tening ring of the sensor. Contact Alfa
Romeo Authorized Services.
Strong radio-frequency disturbances
could inhibit proper TPMS system oper-
ation. This condition is indicated by a
dedicated massage on the display. This
indication will go off automatically as
soon as the radio-frequency disturbance
ceases.If the car is fitted with T.P.M.S. system,
tyre and/or rim removal and refitting
operations involve special precautions;
to prevent damages or wrong sensor re-
fitting, contact Alfa Romeo Authorized
Services to have tyre and/or rim
changed.
