Situations Where Momentary, or No Detection is Experienced
Your system utilizes highly advanced Ultrasonic technology to locate objects in your vehicle’s path. Under some
circumstances however, an object may not be detected. Always use extreme caution when reversing, looking
behind your vehicle and maintaining speeds of less than 3 miles-per-hour.
A small object, which is under your bumper or
too close to the vehicle, may not be detected due to the
dispersion of the sensor’s signal.
When reversing down a steep slope or driveway, gravel
and/or the road surface may cause momentary detection
signals due to the sensors following the sloping angle of
the vehicle
Reversing on loose gravel, rough surfaces, and pot holes
may produce intermittent detection due to the signal
bouncing off of reflective surfaces behind the vehicle.
