WARNING
• The warning light on the side view
mirror will illuminate whenever a
vehicle is detected at the rear side by
the system.
To avoid accidents, do not focus only
on the warning light and neglect to
see the surrounding of the vehicle.
• Drive safely even though the
vehicle is equipped with Blind-Spot
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
high volume may offset the Blind-
Spot Collision Warning system
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
tire, 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.

WARNING
• The driver is responsible for accurate
steering.
• Do not unnecessarily operate the
steering wheel, when Blind-Spot
Collision-Avoidance Assist system is
in operation.
• Always pay extreme caution while
driving. The Blind-Spot Collision-
Avoidance Assist system may not
operate or unnecessarily operate
in accordance with your driving
situations.
• Blind-Spot Collision-Avoidance
Assist system is not a substitute
for safe driving practices, but a
convenience function only. It is
the responsibility of the driver to
always drive cautiously to prevent
unexpected and sudden situations
from occurring. Pay attention to the
road conditions at all times.

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.

Information
The system may suggest a break according
to the driver’s driving pattern or habits
even if the driver doesn’t feel fatigue.
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
from hearing Driver Attention Warning
system warning sounds.

tecting 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

Front radar
The front radar is a sensor detecting
v
ehicles in front and maintains the
distance between them. 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.
CAUTION
•
Do not apply license plate frame or
foreign objects such as a bumper
sticker or a bumper guard near the
radar sensor. Doing so may adversely
affect the sensing performance of
the radar.
• Always keep the radar sensor and
lens 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.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly
moved out of proper alignment,
Smart Cruise Control system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, Smart Cruise Control
system may not operate properly.
Have the vehicle inspected by an
authorized HYUNDAI dealer.
• Use only genuine HYUNDAI parts to
repair or replace a damaged sensor
or sensor cover. Do not apply paint to
the sensor cover.

Information
• Navigation-based Smart Cruise Control
is limited in other countries.
• The system may not operate due to the
existence of leading vehicles and the
driving situations of the vehicle.
• The system operates regardless of
whether the sharp curve warning
appears on the navigation, but the time
gap could occur between the warning
and system operation.
• The navigation only provides curve
information within permitted speed
ranges so that the system may not
decrease its speed during extreme over-
speed driving.
• The system is not designed to work on
highways other than mentioned as a
controlled access road.
• The system automatically cancels when
you leave the highway. •
Highway Driving Assist and
Navigation-based Smart Cruise
Control uses the same symbol
that indicates the status of the system.
Therefore, even if Navigation-based
Cruise Control is off, the
symbol
may be displayed.
• If there is a problem with Navigation-
based Smart Cruise Control, the system
cannot be activated in the AVN system
screen, and the
symbol will turn
off. However, if Highway Driving Assist
is activated, the
symbol will be
displayed.
• After you pass through a tollgate on a
highway, the system operates based
on the first lane. If you enter one of
the other lanes, the system might not
properly decelerate.
• If you over speed, the system may not
decelerate the vehicle in a curve.
• Deceleration by the system may not be
sufficient if the driver accelerates while
the system is operating,
• Deceleration by the system may not be
sufficient due to road conditions such
as uneven road surfaces, narrow lanes,
etc.
• If the road is controlled, due to
construction or holiday events, the
system might not work properly.
