PARKING SENSORS — IF EQUIPPED
They are located in the rear bumper and their function
is to detect the presence of any obstacles near the rear
part of the vehicle; they consequently inform the driver,
through an intermittent acoustic signal.
Activation/Deactivation
The sensors are automatically activated when reverse
gear is engaged. As the obstacle behind the vehicle gets
closer, the acoustic signal becomes more frequent.
Acoustic Signal
When reverse gear is engaged and there is an obstacle
behind the vehicle, an acoustic signal is emitted which
varies according to the distance of the bumper from the
obstacle.
The frequency of the acoustic signal:
•Increases as the distance between vehicle and ob-
stacle decreases, culminating in a continuous acous-
tic signal when the distance is less than approxi-
mately 12 in (30 cm).
• Decreases if the distance from the obstacle increases,
until the signal ceases entirely.
• Remains constant if the distance between vehicle and
obstacle remains unchanged; if this situation con-
cerns the side sensors, the signal will stop after
approximately 3 seconds, for example, in the event of
manoeuvres along a wall.
If several obstacles are detected by the sensors, only the
nearest one is considered.

Indications On Display — If Equipped
When the sensors are activated, the screen appears on
the instrument cluster display.
Obstacle presence and distance information is therefore
provided both by the acoustic signal and the instrument
cluster display.
The system indicates a detected obstacle by displaying
an arc in one or more positions according to the distance
of the obstacle and its position in relation to the vehicle.If an obstacle is detected in the rear central area, the
instrument cluster display shows all the arcs in the rear
central area, up to the one that corresponds to the
position of the obstacle itself.
The signal is similar for obstacles in the rear left or right
area.
The arc that corresponds to the position of the obstacle
will flash.
The color on the instrument cluster display depends on
the distance from and position of the obstacle.
The vehicle is close to the obstacle when the instrument
cluster display shows a single constant arc and emits a
continuous sound.
If there are several obstacles, the closest one is indi-
cated.
Fault Indication
Parking sensor failures, if any, will be indicated when
reverse is engaged by the switching on of the
warn-
ing light in the instrument cluster display.

General Warnings
When parking, take the utmost care over obstacles that
may be above or under the sensor.
Under certain circumstances, objects close to the vehicle
are not detected by the system and could therefore
cause damage to the vehicle or be damaged themselves.
Some conditions may influence the performance of the
parking sensors:
•The presence of ice, snow, mud or multiple layers of
paint on the sensor surface may cause reduced
sensitivity of the sensor itself and therefore reduce
the system performance.
• Mechanical interference (e.g washing the vehicle,
rain, strong wind, hail) may cause the sensor to
detect a non-existent obstacle (“echo interference”).
• The presence of ultrasonic systems (e.g. pneumatic
brake systems of trucks or pneumatic drills) near the
vehicle could alter the signals sent by the sensor.
•
The variation in sensor position, caused by variation in
ride (due to suspension component wear), changing tires, overloaded vehicle, or tuning that lowers the
vehicle, for example, may affect parking sensor system
performance.
NOTE:
The sensor must be free from mud, dirt snow or
ice in order for the system to operate correctly. Be
careful not to scratch or damage the sensors while
cleaning them. Avoid using dry, rough or hard cloths.
The sensors must be washed using clean water, with the
addition of car shampoo if necessary. When using
special washing equipment such as high pressure jets or
steam cleaning, clean the sensors very quickly keeping
the jet more than 4 in (10 cm) away. Also, do not apply
stickers to the sensors.
WARNING!
Drivers must be careful when backing up even when
using the Parking Sensor system. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible
for the safety of your surroundings and must con-
tinue to pay attention while backing up. Failure to do
so can result in serious injury or death.

CAUTION!
•The Parking Sensor system is only a parking aid
and it is unable to recognize every obstacle,
including small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will
not be detected when they are in close proximity
• The vehicle must be driven slowly when using
the Parking Sensor system in order to be able to
stop in time when an obstacle is detected. It is
recommended that the driver looks over his/her
shoulder when using the Parking Sensor system.
POWER OUTLETS
Your vehicle is equipped with a 12 Volt (13 Amp) power
outlet that can be used to power cellular phones, small
electronics and other low powered electrical accesso-
ries. The power outlet is located on the central tunnel,
between the two cup holders. It only operates with the
ignition key at MAR/ON.
