Driver Assistance System
Blind-Spot Collision Warning
disabled
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 Blind-Spot
Collision Warning.
If this occurs, the 'Blind-Spot Safety
system disabled. Radar blocked' warning
message will appear on the cluster.
Blind-Spot Collision Warning will operate
properly when such foreign material or
trailer, etc., is removed, and then the
engine is restarted.
If Blind-Spot Collision Warning does not
operate properly after it is removed, have
the vehicle inspected by an authorized
HYUNDAI dealer.

the engine is turned on, or when
the detecting sensor is blocked
with foreign material right after the

engine is turned on.
CAUTION

to install or remove a trailer, carrier, or
another attachment. Turn on Blind-Spot
Collision Warning when finished.
