more information.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the reverse gear is selected.
The RSS will assist the driver in detecting certain objects while the
vehicle slowly moves in reverse at speeds less than 8 km/h (3 mph). The
RSS is not effective at speeds greater than 8 km/h (3 mph) and may not
detect certain angular or moving objects. The weather may also affect
the function of RSS. RSS may have reduced performance in the rain or
snow.
