• Changing lanes
OADAS032[A] : Your vehicle,
[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
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.
OADAS033[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.

WARNING
• Driving on a curve
OADAS014
OADAS016OADAS018
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.
OADAS015
OADAS017OADAS019
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 system may
unnecessarily warn the driver and
control the brake. Always check the
traffic conditions around the vehicle.

• Driving on a slope
OADAS012
OADAS010OADAS011
Forward Collision-Avoidance Assist
may not detect other vehicles,
pedestrians or cyclists in front of
you while 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
while 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. •

OHY059004
When you are driving forward out of
a parking space, if the system judges
that there is a collision risk with an
approaching vehicle in the blind spot,
the function will help avoid a collision by
applying the brake.
Information
In the following text, Blind-Spot Collision-
Avoidance Assist will be referred as Blind-
Spot Safety system.
Detecting sensor
OCN7060030
OCN7060046[1] : Front view camera,
[2] : Rear corner radar
Refer to the picture above for the
detailed location of the detecting
sensors.
CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensor:
• Never disassemble the rear corner
radar or radar assembly, or apply any
impact on it.
• If there is impact on the rear
corner radar or near the radar,
even though the warning message
does not appear on the cluster,
Blind-Spot Safety system may not
operate properly. We recommend
that the system be inspected by an
authorized HYUNDAI dealer.

• Changing lanes
OADAS030 [A] : Your vehicle, [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. Smart Cruise
Control 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, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance. •
