Warning message
The message will appear to notify the
driver if there are foreign substances
on the surface or inside the rear bump‐
er or it is hot near the rear bumper.
The light on the switch and the system
will be turned off automatically.
Remove the foreign substance on the
rear bumper.
After the foreign substance is removed,
if you drive for approximately 10 mi‐
nutes, the system will work normally.
If the system does not work normally
even though the foreign substance,
trailer or carrier, or other equipment is
removed, take your vehicle to a profes‐
sional workshop and have the system
checked. Kia recommends to visit an
authorized Kia dealer/service partner.
It is possible to get the message with
no foreign substance on the rear
bumper, for example, when driving in
sparse rural or open area, such as des‐
ert, where there is insufficient data for
operation.
This message may also activate during
heavy rain or due to road spray.
In this case, the vehicle does not need
service.
When the cargo area or other equip‐
ment is being used, turn all functions of
the system [OFF].
If the system does not work properly, a
warning message will appear and the
light on the switch will turn off. The
system will turn off automatically.
