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
or cyclist ahead is suddenly detected.
Always have your eyes on the road
whilst driving uphill or downhill and
if necessary, steer the vehicle and
depress the brake pedal to reduce
your driving speed in order to
maintain a safe distance.

[Changing lanes
OADAS032R[A] : Your vehicle, [B] : Lane changing vehicle
hen 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
maintain a safe braking distance,
and if necessary, steer the vehicle
and depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
OADAS033R[A] : Your vehicle, [B] : Lane changing vehicle,
[C] : Same lane vehicle
When a vehicle in front of you
merges out of the lane, Forward
Collision-Avoidance Assist may not
immediately detect the vehicle that is
now in front of you.
In this case, you must maintain a safe
braking distance, and if necessary,
steer the vehicle and depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance.

[Detecting vehicle
OBC3070005
If the vehicle in front of you has
cargo that extends rearward from
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
vehicle. In these instances, you must
maintain a safe braking distance from
the rearmost object, and if necessary,
steer the vehicle and depress the
brake pedal to reduce your driving
speed in order to maintain distance.
WARNING

[When you are towing a trailer or
another vehicle, we recommend that
Forward Collision-Avoidance Assist is
turned off due to safety reasons.

[Forward Collision-Avoidance Assist
may operate if objects that are
similar in shape or characteristics to
vehicles, pedestrians and cyclists are
detected.

[Forward Collision-Avoidance Assist
does not operate on bicycles,
motorcycles, or smaller wheeled
objects, such as luggage bags,
shopping carts, or strollers.

[Forward Collision-Avoidance
Assist may not operate normally if
interfered by strong electromagnetic
waves.

[Forward Collision-Avoidance Assist
may not operate for 15 seconds after
the vehicle is started, or the front
view camera is initialized.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensor:

[Never disassemble the detecting
sensor or sensor assembly, or apply
any impact on it.

[If the detecting sensors have been
replaced or repaired, we recommend
that you have your vehicle inspected
by a HYUNDAI authorised repairer.

[Never install any accessories or
stickers on the front windscreen, or
tint the front windscreen.

[Pay extreme caution to keep the
front view camera dry.

[Never place any reflective objects
(i.e. white paper, mirror) over the
dashboard. Any light reflection
may prevent the function from
functioning properly.

[Do not apply license plate frame or
objects, such as a bumper sticker,
film or a bumper guard, near the
front radar cover.

[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.
[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.

[Use only genuine parts to repair or
replace a damaged front radar cover.
Do not apply paint to the front radar
cover.

WARNING
Take the following precautions when
using Forward Collision-Avoidance
Assist:

[For your safety, change the Settings
after parking the vehicle at a safe
location.

[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.

[Forward Collision-Avoidance Assist
does not operate in all situations or
cannot avoid all collisions.

[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.

[Never deliberately operate Forward
Collision-Avoidance Assist on people,
animal, objects, etc. It may cause
serious injury or death.

[Forward Collision-Avoidance
Assist may not operate if the driver
depresses the brake pedal to avoid
collision.
[Depending on the road and driving
conditions, Forward Collision-
Avoidance Assist may warn the driver
late or may not warn the driver.

[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.

[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.

[You may not hear the warning sound
of Forward Collision-Avoidance Assist
if the surrounding is noisy.

[Forward Collision-Avoidance
Assist may turn off or may not
operate properly or may operate
unnecessarily depending on the road
conditions and the surroundings.
WARNING

[Even if there is a problem with
Forward Collision-Avoidance
Assist, the vehicle’s basic braking
performance will operate normally.

[During emergency braking,
braking control by the function will
automatically cancel when the driver
excessively depresses the accelerator
pedal or sharply steers the vehicle.
