Collision-Avoidance Assist system.
Do not solely rely on the system
but check your surrounding before changing lanes or backing the
vehicle up.
• The system may not alert the driver
in some conditions so always check
your surroundings while driving.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not the
warning light on the side view mirror
illuminates or there is a warning alarm.
• Playing the vehicle audio system at

warning sounds.
• The warning of Blind-Spot Collision-
Avoidance Assist system may not
sound while other system’s warning sounds. Blind-Spot Collision-Avoidance
Assist
Blind-Spot Collision-Avoidance Assist
system may apply braking power, when
an approaching vehicle is detected
within a certain distance next to or
behind your vehicle.
It gently applies braking power on the
wheel, which is located in the opposite
side of the possibly-colliding point. The
instrument cluster will inform the driver
of the system activation.
Blind-Spot Collision-Avoidance Assist
system is automatically deactivated when:
- The vehicle drives a certain distance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in the
middle of the vehicle lanes to keep the
system in the ready status.
When the vehicle drives too close to one
side of the vehicle lanes, the system may
not properly operate.
In addition, the system may not properly
control your vehicle in accordance with
driving situations. Thus, always pay close
attention to road situations.

(Front view camera and Rear
corner radar)
„„Front view camera
ODN8A069024
„„Rear corner radars
ODN8069031L
Front view camera
The front view camera is a sensor
detecting the lane. If the sensors are
covered with snow, rain or foreign
substance, the system may temporarily
be cancelled and not work properly
until the system is cancelled due to the
degradation of the sensor’s detection
performance. Always keep the sensor clean.  Refer to Lane Keeping Assist (LKA) for
cautions for the front view camera.

06
6-83
Rear corner radar
The rear corner radars are the sensors
inside the rear bumper for detecting the
side and rear areas. Always keep the rear
bumper clean for proper operation of the
system.
CAUTION
• The system may not work properly when the bumper has been
damaged, or if the rear bumper has
been replaced or repaired.
• The sensing range differs somewhat
according to the width of the road.
When the road is narrow, the system
may detect other vehicles in the next
lane. On the other hand, when the
road is wide, the system may not
detect vehicles on both lanes and
may not warn.
• The system may turn off due to
strong electromagnetic waves.
• Always keep the sensors clean.
• NEVER arbitrarily disassemble the
sensor component nor apply any
impact on the sensor component.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, the system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer. •
Do not apply foreign objects such as
a bumper sticker or a bumper guard
near the radar sensor or apply paint
to the sensor area. Doing so may
adversely affect the performance of
the sensor.
• NEVER install any accessories or
stickers on the front windshield, nor
tint the front windshield.
• Pay extreme caution to keep the
front view camera out of water.
• NEVER locate any reflective objects
(i.e. white paper, mirror) over the
crash pad. Any light reflection may
cause a malfunction of the system.
