Function malfunction and
limitations
Function malfunction
ODN8A070030When 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
