Driving your vehicle
Detecting vehicles
The sensor may be limited when:
• The radar sensor or camera is cov-
ered with a foreign object or debris
• The camera lens is contaminated
due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
• Inclement weather such as heavy
rain or snow obscures the field of
view of the radar sensor or camera
• There is interference by electro-
magnetic waves
• Something in the path of travel
deflects the radar waves.
• The radar/camera recognition is
limited
• The vehicle in front is too small to
be detected (for example a motor-
cycle or a bicycle, etc.)
• The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the camera recog-
nition system. (for example a trac-
tor, trailer, etc.)
