If it still does not work properly,
we recommend that the system be
inspected by an authorized HYUNDAI
dealer.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensors:
• Always keep the rear view camera
and rear ultrasonic sensors clean.
• Do not use any cleanser containing
acid or alkaline detergents when
cleaning the rear view camera lens.
Use only a mild soap or neutral
detergent, and rinse thoroughly with
water.
• Never disassemble or apply impact
on the rear view camera or the rear
ultrasonic sensors components.
• Do not apply unnecessary force on
the rear view camera or the rear
ultrasonic sensors. The system may
not operate properly if the rear
view camera or the rear ultrasonic
sensor(s) is forcibly moved out of
proper alignment. We recommend
that the vehicle be inspected by an
authorized HYUNDAI dealer.
• Do not spray the rear view camera or
the rear ultrasonic sensors or their
surrounding area directly with a
high pressure washer. It may cause
the rear view camera or the rear
ultrasonic sensors to malfunction.
• The function may not work properly
if the bumper has been damaged,
replaced or repaired.
• Do not apply objects, such as a
bumper sticker or a bumper guard,
near the rear view camera or rear
ultrasonic sensors or apply paint to
the bumper. Doing so may adversely
affect the performance of the
function.
• Reverse Parking Collision-Avoidance
Assist may not operate normally if
interfered by strong electromagnetic
waves.
