RADIO TRANSMITTERS AND CELLULAR PHONES
Radio transmitting equipment (vehicle mobile phones, CB radios,
amateur radio etc.) shall not be used inside the car unless a sep-
arate aerial is mounted on the roof.
IMPORTANT The use of these devices inside the passenger com-
partment (without a separate aerial) may cause the vehicle elec-
trical systems to malfunction. This could compromise safety in ad-
dition to constituting a potential hazard for passengers’ health.
In addition, transmission and reception of these devices may be af-
fected by the shielding effect of the car body. As far as the use of
EC-approved mobile phones is concerned (GSM, GPRS, UMTS), fol-
low the instructions for use provided by the mobile phone manu-
facturer.
PARKING SENSORS
(for versions/markets, where provided)
The parking sensors are located on the rear bumper fig. 88 and
their function is to inform the driver, through an intermittent beep-
ing, of the presence of obstacles behind the car.
TURNING THE SENSORS ON
The sensors are turned on when reverse gear is engaged. As the
distance from the obstacle behind the car decreases, the beeping
becomes more frequent.

DISPLAY INDICATIONS
(for versions/markets, where provided)
When the sensor is activated, the "Reconfigurable multifunctional
display" (for versions/markets where provided) shows the screen
illustrated in fig. 88a; the information about the presence of and
distance from the obstacle is given by the buzzer and also by a
visual indication on the instrument panel display. If there are se-
veral obstacles, the closest one is indicated.
BUZZER WARNINGS
When reverse gear is engaged a buzzer warning is automatically
activated if there is an obstacle within the range of operation.
The acoustic signal:
❍increases as the distance between the car and the obstacle de-
creases;
❍becomes continuous when the distance between the car and
the obstacle is less that 30 cm and stops immediately if the
distance increases;
❍remains constant if the distance between the vehicle and the
obstacle remains unchanged, whilst if this situation occurs for
the side sensors, the signal is interrupted after about 3 seconds,
for example, to prevent signals in the case of manoeuvres along-
side walls.
IMPORTANT The volume of the audible signal can be adjusted th-
rough the option "Warnings volume" of the "Set-Up menu".
OPERATION WITH TRAILER
Parking sensor operation is automatically turned off when the trail-
er electric cable plug is fitted into the car tow hook socket. The sen-
sors are automatically enabled again when the trailer cable plug
is removed.
The sensor must be free of mud, dirt, snow or ice
in order for the system to work. Be careful not to
scratch or damage the sensors while cleaning them.
Avoid using dry, rough or hard cloths. The sensors should
be washed using clean water with the addition of car sham-
poo if necessary. In washing stations, clean sensors quick-
ly keeping the vapour jet/high pressure washing noz-
zles at a distance of at least 10 cm from the sensors.

CONTENTS
The ultimate responsibility when parking and car-
rying out other dangerous manoeuvres still rests
with the driver. When carrying out such manoeu-
vres, always ensure that the manoeuvring area is free
of people (particularly children) and animals. Parking sen-
sors are designed to assist drivers; however, you must al-
ways concentrate fully during potentially dangerous ma-
noeuvres, even if carried out at low speeds.
GENERAL WARNINGS
During parking manoeuvres, pay the utmost attention to any ob-
stacles that could be located above or below the sensors.
Sometimes, objects located close to the rear part of the car may
not be detected by the system and may damage the car or become
damaged themselves.
Here below are some conditions that may influence the perfor-
mance of the parking system:
❍Reduced sensor sensitivity and a reduction in the parking as-
sistance system performance could be due to the presence on
the surface of the sensor of: ice, snow, mud, thick paint.
❍the sensor may detect a non-existent obstacle (echo noise) due
to mechanical noises, for example when washing the vehicle,
in case of rain, strong wind, hail.
❍the signals sent by the sensors can also be altered by the pres-
ence of ultrasound devices (e.g. pneumatic brake systems or
pneumatic drills) near the car;
❍sensor performance can also be influenced by the position of
the sensors. For example by a change in the ride setting (caused
by the wear of the shock absorbers, suspension), overloading
the car and carrying out specific tuning operations that require
the car to be lowered;
❍the detection of obstacles at the top part of the vehicle may
not be guaranteed because the system detects obstacles that
could cause an impact with the vehicle in the bottom part.
For repainting the bumpers or retouching the paint-
work around the sensors contact Alfa Romeo
Authorized Services. Incorrect application of paint
may compromise the operation of the parking sensors.
