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.

NOTICE
• Driver Attention Warning system
utilizes the camera sensor on the
front windshield for its operation. To
keep the camera sensor in the best
condition, you should observe the
followings:
• Never install any accessories or
stickers on the front windshield, or
tint the front windshield.
• NEVER place any reflective objects
(i.e. white paper, mirror) over the
dashboard. Any light reflection
may cause a malfunction of Driver
Attention Warning system.
• Pay extreme caution to keep the
camera sensor dry.
• Never disassemble the camera
assembly, or apply any impact on the
camera assembly.
If the sensor is forcibly moved out
of proper alignment, the system
may not operate correctly. Have the
vehicle inspected by an authorized
HYUNDAI dealer.
CAUTION
• Driver Attention Warning system may
not provide alerts in the following
situations:
• Driver Attention Warning system
is using the front view camera. To
optimize the function of the front
view camera, the driver should
manage carefully. For detailed
information, please refer to the
warning statements in Lane Keeping
Assist system section.
• The lane detection performance
is limited. (For more information,
refer to “Lane Keeping Assist (LKA)”
section in this chapter.)
• The vehicle is erratically driven
or is abruptly turned for obstacle
avoidance (e.g. construction area,
other vehicles, fallen objects, bumpy
road).
• Forward drivability of the vehicle is
severely undermined (possibly due
to wide variation in tire pressures,
uneven tire wear-out, toe-in/toe-out
alignment).
• The vehicle is driven on a curvy road.
• The vehicle is driven through a windy
area.
• The vehicle is driven on a bumpy
road.
• The vehicle is controlled by the
following driving assist systems:
- Forward Collision-Avoidance Assist
system
- Lane Keeping Assist system
- Smart Cruise Control system
- Lane Following Assist system
CAUTION
Playing the vehicle audio system at
high volume may prevent occupants

•
Do not place objects on the
dashboard that reflects light such as
mirrors, white paper, etc. This may
prevent LFA system from functioning
properly.
• Always have your hands on the
steering wheel while LFA system is
activated. If you continue to drive
with your hands off the steering
wheel after the “Keep hands on
steering wheel” warning message
appears, the system will turn off
automatically.
However, if the driver has their
hands on the steering wheel again,
the system will start controlling the
steering wheel.
• The steering wheel is not
continuously controlled so if the
vehicle speed is at a higher rate
when leaving a lane the vehicle may
not be controlled by the system. The
driver must always follow the speed
limit when using the system.
• If you attach objects to the steering
wheel, the system may not assist
steering or the hands off alarm may
not work properly.
