PARKING SENSORS
(where provided)
Parking sensors inform the driver about
the presence of obstacles behind the car
(versions fitted with 4 rear sensors) or
behind and in front of the car (versions
fitted with 4 rear sensors and 4 front
sensors).
This system is therefore an aid for the
driver when parking the car since it de-
tects obstacles out of the driver’s sight
range.
The presence and the distance from the
car of an obstacle is indicated by a warn-
ing buzzer - as the distance from the ob-
stacle decreases, the acoustic alarm be-
comes more frequent - and, only on cer-
tain versions, by an image on the dis-
play (see paragraph “Indications on the
display).

ACTIVATION
Versions with 4 sensors
Front sensors are automatically activat-
ed with electronic key fitted into the ig-
nition device when reverse gear is en-
gaged or when pressing the front ceil-
ing light button A-fig. 103 with speed
below 15 km/h.
Sensors are deactivated when exceed-
ing 18 km/h or, on certain versions by
pressing again the button if the speed is
lower than 15 km/h A-fig. 103. If
the system is off on versions with de-
activation button, the button led is off.Versions with 8 sensors
Front and rear sensors are automatical-
ly activated with electronic key fitted in-
to the ignition device when reverse gear
is engaged or when pressing the front
ceiling light buttonA-fig. 103with
speed below 15 km/h.
Sensors are deactivated by pressing
again button A-fig. 103if the speed
is lower than 15 km/h or when ex-
ceeding 18 km/h. If the system is off,
the button led is off.
When sensors are on, front and rear in-
dicators will sound warning signals as
soon as an obstacle is detected: as the
distance from the obstacle decreases,
the acoustic alarm becomes more fre-
quent.
When the distance between the car and
the obstacle is less than 30 cm, the
acoustic alarm becomes continuous. Ac-
cording to obstacle position (in front or
behind the car), the acoustic alarm will
be emitted by front or rear indicators.
In any case the system will indicate the
obstacle closest to the car.

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.106; 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)
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.

Since this filter physically traps particu-
lates, it shall be cleaned (reclaimed) at
regular intervals by burning carbon par-
ticles. Reclaiming procedure is controlled
automatically by the engine control unit
according to the filter conditions and the
conditions of use of the car. During re-
claiming the following phenomena could
take place: idling slight increase, fan ac-
tivation, slight smoke increase, high ex-
haust temperatures. These situations
shall not be considered as faults and they
do not affect car performance and envi-
ronment.DIESEL PARTICULATE FILTER
(DPF)
The Diesel Particulate Filter is a me-
chanical filter, integral with the exhaust
system, that physically traps particulate
present in the exhaust gases of Diesel
engines.
The diesel particular filter has been
adopted to eliminate almost totally par-
ticulates in compliance with current /
future law regulations.
During normal use of the car, the engine
control unit records a set of data (e.g.:
travel time, type of route, temperatures,
etc.) and it will then calculate how much
particulates has been trapped by the fil-
ter.Diesel particulate filter
clogged
When the Diesel particulate filter is
clogged, the instrument panel warning
light
hwill turn on (on certain ver-
sions symbol
his displayed). In
this case keep the car running until
warning light
h(or symbol
h) turns off.

S.B.R. SYSTEM
(Seat Belt Reminder)
The car is fitted with the S.B.R. system
(Seat Belt Reminder), consisting of a
buzzer which, together with the turning
on of warning light
ing light panel, warns the driver and the
front passenger to fasten the seat belt.
The buzzer can be muted temporarily by
the following procedure:
❒fasten the front seat belts;
❒fit the electronic key into the ignition de-
vice;
❒wait for over 20 seconds but less than
1 minute and then unfasten one of the
front seat belts.
This procedure will stand valid till next en-
gine switching off.
For permanent deactivation, contact Alfa
Romeo Authorized Services. The S.B.R.
system can only be reset through the set-
up menu (see paragraph “Reconfigurable
multifunction display“ in section “Dash-
board and controls”). IMPORTANT On certain versions, cor-
rect backrest fastening is guaranteed
when the “red band” A-fig. 3aside
leversBis no longer visible. The “red
band” actually indicates that the back-
rest is not properly secured.
IMPORTANTAfter putting the seats
back to their travelling position, restore
the seat belt position to make them
ready for use.
A0E0085mfig. 3
Make sure the backrest
is properly secured at
both sides (red band A-fig. 3
not visible) to prevent it moves
forward in the event of sharp
braking causing injuries to pas-
sengers.
WARNING
Remember that in the
event of a violent colli-
sion, back seat passengers not
wearing seat belts also repre-
sent a serious danger for the
front seat passengers.

GENERAL WARNINGS
If when fitting the key
into the ignition device,
the warning light
¬does not
turn on or if it stays on when
travelling (on certain versions
together with the message on
the display) there could be a
failure in safety systems; in
this event air bags or preten-
sioners could not trigger in
case of impact or, in a minor
number of cases, they could
trigger accidentally. Contact
Alfa Romeo Authorized Ser-
vices immediately to have the
system checked.
WARNING
Do not cover the back-
rest of front seats with
trims or covers that are not
suitable to be used with side
bags.
WARNING
Never travel with ob-
jects on your lap, in
front of your chest or with a
pipe, pencil, etc. between your
lips; injury may result in the
event of the air bag being trig-
gered.
WARNING
Always keep your
hands on the steering
wheel rim when driving, so
that if the air bag is triggered,
it can inflate without meeting
any obstacles which could
cause serious harm to you. Do
not drive with the body bent
forwards, keep the seat back
rest in the erect position and
lean your back well against it.
WARNING
If the car has been
stolen or an attempt to
steal it has been made, if it
has been subjected to vandals
or floods, have the air bag
system checked by Alfa Romeo
Authorized Services.
