the camera lens is covered with foreign

material, such as snow or rain, it may

adversely affect camera performance

and Reverse Parking Collision-Avoidance

Assist may not operate normally. Always

keep the camera lens clean.

WARNING

Take the following precautions when

using Reverse Parking Collision-

Avoidance Assist:

śꢀ Always pay extreme caution whilst

driving. The driver is responsible for

controlling the brake for safe driving.

śꢀ Always pay attention to road and

traffic conditions whilst driving,

whether or not there is a warning.

CAUTION

śꢀ Noise may be heard when sudden

braking occurs to avoid a collision.

śꢀ If any other warning sound such

as the seat belt warning chime is

already generated, Reverse Parking

Collision-Avoidance Assist warning

may not sound.

śꢀ Reverse Parking Collision-Avoidance

Assist may not work properly if the

bumper has been damaged, replaced

or repaired.

śꢀ Reverse Parking Collision-Avoidance

Assist may not operate normally if

interfered by strong electromagnetic

waves.

śꢀ Playing the vehicle audio system at

high volume may prevent passengers

from hearing Reverse Parking

Collision-Avoidance Assist warning

sounds.

śꢀ Turn off Reverse Parking Collision-

Avoidance Assist when towing a

trailer. If towing and moving in

reverse, Reverse Parking Collision-

Avoidance Assist will activate as it

detects the trailer.

śꢀ The brake control may not operate

properly depending on the status of

ESC (Electronic Stability Control).

śꢀ Always look around your vehicle to

make sure there are no pedestrians

or objects before moving the vehicle.

śꢀ The performance of Reverse Parking

Collision-Avoidance Assist may vary

under certain conditions. If vehicle

speed is above 4 km/h, Reverse

Parking Collision-Avoidance Assist

will provide collision avoidance

assist only when pedestrians are

detected. Always look around and

pay attention when backing up your

vehicle.

śꢀ Some objects may not be detected

by the rear ultrasonic sensors due

to the objects distance, size or

material, all of which can limit the

effectiveness of the sensor.

śꢀ Reverse Parking Collision-Avoidance

Assist may not operate properly

or may operate unnecessarily

depending on the road conditions

and the surroundings.

śꢀ Do not solely rely on Reverse Parking

Collision-Avoidance Assist. Doing

so may lead to vehicle damage or

injuries.

There will only be a warning when:

- The ESC (Electronic Stability

Control) warning light is on

- ESC (Electronic Stability Control) is

engaged in a different function

CAUTION

Take the following precautions to

maintain optimal performance of the

detecting sensors:

Information

Reverse Parking Collision-Avoidance

Assist can detect a pedestrian or an object

when:

śꢀ Always keep the rear view camera

śꢀ A pedestrian is standing behind the

vehicle

and rear ultrasonic sensors clean.

śꢀ 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.

śꢀ A large obstacle, such as a vehicle,

is parked in the rear centre of your

vehicle

śꢀ 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.

śꢀ 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 Reverse

Parking Collision-Avoidance Assist.

śꢀ Never disassemble or apply impact

on the rear view camera or the rear

ultrasonic sensors components.

śꢀ Do not apply unnecessary force on

the rear view camera or the rear

ultrasonic sensors. Reverse Parking

Collision-Avoidance Assist 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

authorised HYUNDAI dealer.
