foreign object.
- Driving in rural areas where the sensor does not detect another vehicle for an
extended period of time.
- When there is inclement weather such as heavy snow or rain.
- A trailer or carrier or another object is installed around the rear view radars.
If any of these conditions occur, the
system will turn off automatically.
When 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
sensors are located. Remove any dirt,
snow, or foreign material that could
interfere with the radar sensors.
After any dirt or debris is removed, the
system should operate normally after
about 10 minutes of driving the vehicle.
If the system still does not operate
normally have your vehicle inspected by
an authorized HYUNDAI dealer.

Function malfunction and
limitations
Function malfunction
ODN8A070030
When Safe Exit Assist is not working
properly, the ‘Check Blind-Spot Safety
system’ warning message will appear
on the cluster, and the system will turn
off automatically or the system will be
limited. We recommend that the system
be inspected by an authorized HYUNDAI
dealer. Function disabled
OCN7070041L
When the rear bumper around the rear
corner radar or sensor is covered with
foreign material, such as snow or rain,
or installing a trailer or carrier, it can
reduce the detecting performance and
temporarily limit or disable Safe Exit
Assist.
If this occurs, the ‘Blind-Spot Safety
function disabled. Radar blocked’
warning message will appear on the
cluster.
The function will operate normally
when such foreign material or trailer,
etc. is removed, and then the engine is
restarted.
If the function does not operate normally
after it is removed, we recommend
that the system be inspected by an
authorized HYUNDAI dealer.

not detected right after the engine
is turned on, or when the detecting
sensor is blocked with foreign
material right after the engine is turned on.
CAUTION
Turn off Safe Exit Assist to install a
trailer, carrier, etc., or remove the
trailer, carrier, etc. to use Safe Exit
