Fault Indication
Parking sensor failures, if any, will be indicated when
REVERSE gear is engaged by the switching on of the
warning 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), chang-
ing 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 inches (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 carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing up. You
are responsible for the safety of your surroundings
