WARNING

[Driving on a curve
OADAS003R
OADAS002R
OADAS001R
Forward Collision-Avoidance Assist
may not detect other vehicles,
pedestrians or cyclists in front of you
on curved roads adversely affecting
the performance of the sensors. This
may result in no warning or braking
assist when necessary. When driving on a curve, 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.
OADAS006R
OADAS005R
OADAS004R
Forward Collision-Avoidance Assist
may detect a vehicle, pedestrian or
cyclist in the next lane or outside the
lane when driving on a curved road.
If this occurs, the function may
unnecessarily warn the driver and
control the brake. Always check the
traffic conditions around the vehicle.

[Driving on a slope
OADAS009R
OADAS007R
OADAS008R
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.

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.
