CAUTION
Conditions which may affect the sensor
■
Do not attach any accessories within the detection range of the sensors.
●
A sensor may not operate properly in the following situations:
●
• There is ice, snow or mud on the sensor. (When it is removed, the normal
operation will return.)

low temperatures in particular, sensors that are frozen may not detect a
parked vehicle.
• When the vehicle is tilted.
• In extreme hot or cold weather.
• When driving on bumpy roads, slopes, gravelled roads or grass.
• Devices issuing ultrasonic waves are operated around your vehicle, such as a
horn from another vehicle, motorcycle engine, air braking sound from heavy-
duty vehicles.
• When rain or water is splashed over the vehicle.
• When a radio antenna or fender pole is mounted on your vehicle.
• The sensor approaches too close to a parked vehicle.
