When you are driving forward out of a
parking space, if Blind-Spot Collision-
Avoidance Assist judges that there is a
collision risk with an approaching vehicle
in the blind spot, it can help avoid a
collision by applying the brake.
Detecting sensor
[1] : Front view camera,
[2] : Rear corner radar
Refer to the picture above for the
detailed location of the detecting
sensors.
Take the following precautions to
maintain optimal performance of the
detecting sensor:
Never disassemble the rear corner
radar or radar assembly, or cause any
damage to it.
If the rear corner radar or near
the radar has been damaged or
impacted in any way even though the
OHY059004 warning message does not appear
on the cluster, Blind-Spot Collision-
Avoidance Assist may not operate
properly. Have the vehicle inspected
by an authorized HYUNDAI dealer.
If the rear corner radars have been
replaced or repaired, have the
vehicle inspected by an authorized
HYUNDAI dealer.
Use only genuine HYUNDAI parts to
repair the rear bumper where the
rear corner radar is located.
Do not apply license plate frame or
objects, such as a bumper sticker,
film or a bumper guard near the rear
corner radar.
Blind-Spot Collision-Avoidance

been applied.
If a trailer, carrier, etc., is installed,
it may adversely affect the
