Forward Collision-Avoidance Assist is

designed to help detect and monitor

the vehicle ahead or help detect a

pedestrian or cyclist in the roadway

and warn the driver that a collision is

imminent with a warning message and

an audible warning, and if necessary,

apply emergency braking.

Junction Turning function will help avoid

a collision with an oncoming vehicle in

an adjacent lane when turning left at

a crossroad with the turn signal on by

applying emergency braking.

Driver assistance system

śꢀ If unnecessary force has been

applied to the radar or around the

radar, Forward Collision-Avoidance

Assist may not properly operate

even though a warning message

does not appear on the cluster. We

recommend that the vehicle be

inspected by a HYUNDAI authorised

repairer.

śꢀ Use only genuine parts to repair or

replace a damaged front radar cover.

Do not apply paint to the front radar

cover.

CAUTION

Take the following precautions to

maintain optimal performance of the

detecting sensor:

śꢀ Never disassemble the detecting

sensor or sensor assembly, or apply

any impact on it.

śꢀ If the detecting sensors have been

replaced or repaired, we recommend

that you have your vehicle inspected

by a HYUNDAI authorised repairer.

śꢀ Never install any accessories or

stickers on the front windscreen, or

tint the front windscreen.

śꢀ Pay extreme caution to keep the

front view camera dry.

śꢀ Never place any reflective objects

(i.e. white paper, mirror) over the

dashboard. Any light reflection

may prevent the function from

functioning properly.

śꢀ Do not apply license plate frame or

objects, such as a bumper sticker,

film or a bumper guard, near the

front radar cover.

śꢀ Always keep the front radar and

cover clean and free of dirt and

debris.

Use only a soft cloth to wash the

vehicle. Do not spray pressurized

water directly on the sensor or sensor

cover.

WARNING

Avoidance Assist may warn the driver

late or may not warn the driver.

Take the following precautions when

using Forward Collision-Avoidance

Assist:

śꢀ For your safety, change the Settings

after parking the vehicle at a safe

location.

śꢀ With ‘Active assist’ or ‘Warning only’

selected, when ESC is turned off by

pressing and holding the ESC OFF

button, Forward Collision-Avoidance

Assist will turn off automatically.

In this case, the function cannot be

set from the Settings menu and the

warning light will illuminate on

the cluster which is normal. If ESC is

turned on by pressing the ESC OFF

button, Forward Collision-Avoidance

Assist will maintain the last setting.

śꢀ During Forward Collision-Avoidance

Assist operation, the vehicle may

stop suddenly injuring passengers

and shifting loose objects. Always

have the seat belt on and keep loose

objects secured.

śꢀ If any other function’s warning

message is displayed or audible

warning is generated, Forward

Collision-Avoidance Assist warning

message may not be displayed

and audible warning may not be

generated.

śꢀ You may not hear the warning sound

of Forward Collision-Avoidance Assist

if the surrounding is noisy.

śꢀ Forward Collision-Avoidance Assist

does not operate in all situations or

cannot avoid all collisions.

śꢀ Forward Collision-Avoidance

Assist may turn off or may not

operate properly or may operate

unnecessarily depending on the road

conditions and the surroundings.

śꢀ The driver should hold the

responsibility to control the vehicle.

Do not solely depend on Forward

Collision-Avoidance Assist. Rather,

maintain a safe braking distance, and

if necessary, depress the brake pedal

to reduce driving speed or to stop the

vehicle.

WARNING

śꢀ Even if there is a problem with

Forward Collision-Avoidance

Assist, the vehicle’s basic braking

performance will operate normally.

śꢀ Never deliberately operate Forward

Collision-Avoidance Assist on people,

animal, objects, etc. It may cause

serious injury or death.

śꢀ Forward Collision-Avoidance

Assist may not operate if the driver

depresses the brake pedal to avoid

collision.

śꢀ During emergency braking,

braking control by the function will

automatically cancel when the driver

excessively depresses the accelerator

pedal or sharply steers the vehicle.

śꢀ Forward Collision-Avoidance Assist

may not properly operate in an

area (e.g. open terrain), where any

substance are not detected after

turning ON the engine.

Limitations of the Forward

Collision-Avoidance Assist

Forward Collision-Avoidance Assist may

not operate normally, or the function

may operate unexpectedly under the

following circumstances:

śꢀ The detecting sensor or the

surroundings are contaminated or

damaged

śꢀ The temperature around the front view

camera is high or low

to tinted, filmed or coated windscreen,

damaged glass, or stuck of foreign

When the front windscreen where the

front view camera is located, front radar

cover or sensor is covered with foreign

material, such as snow or rain, it can

reduce the detecting performance and

temporarily limit or disable Forward

Collision-Avoidance Assist.

If this occurs the 'Forward safety

systems. Camera obscured' or the

'Forward safety systems disabled. Radar

blocked' warning message, and the

warning lights will illuminate on

the cluster.

The function will operate normally when

when such snow, rain or foreign material

is removed.

If the function does not operate normally

after obstruction (snow, rain, or foreign

material) is removed, we recommend

that the function be inspected by a

If this occurs, the function may

unnecessarily warn the driver and

control the brake. Always check the

traffic conditions around the vehicle.

When driving on a curve, you must

maintain a safe braking distance,

and if necessary, steer the vehicle

[A] : Your vehicle,

Forward Collision-Avoidance Assist

may not detect other vehicles,

pedestrians or cyclists in front of

you whilst driving uphill or downhill

adversely affecting the performance

of the sensors.

This may result in unnecessary

warning or braking assist, or no

warning or braking assist when

necessary.

Also, vehicle speed may rapidly

decrease when a vehicle, pedestrian

Always have your eyes on the road

whilst driving uphill or downhill and

if necessary, steer your vehicle and

depress the brake pedal to reduce

your driving speed in order to

maintain a safe distance.

[B] : Lane changing vehicle

When a vehicle moves into your

lane from an adjacent lane, it cannot

be detected by the sensor until it

is in the sensor's detection range.

Forward Collision-Avoidance Assist

may not immediately detect the

vehicle when the vehicle changes

lanes abruptly. In this case, you must

the cab, or when the vehicle in front

of you has higher ground clearance,

additional special attention is

required. Forward Collision-

Avoidance Assist may not be able to

detect the cargo extending from the
