Hyundai Ioniq Hybrid 2020 Owner's Manual page 473

When the BCW canceled warning
message is displayed in the cluster,
check to make sure that the rear
bumper is free from any dirt or snow
in the areas where the sensor is
located. Remove any dirt, snow, or
foreign material that could interfere
with the radar sensors.
After any dirt or debris is removed,
the RCCW system should operate
normally after about 10 minutes of
driving the vehicle.
If the system still does not operate
normally, we recommend that the
vehicle be inspected by an author-
ized HYUNDAI dealer.
Check Blind-Spot Collision
Warning (BCW) system
If there is a problem with BCW sys-
tem, a warning message will appear
and the light on the button will turn
off. The system will turn off automat-
ically. RCCW will not operate also if
BCW system turns off due to mal-
function. We recommend that you
have your vehicle inspected by an
authorized HYUNDAI dealer.

below situations because the system
may not detect other vehicles or

default position.
