Auto Defogging System
(if equipped)
Auto defogging helps reduce the
possibility of fogging up the inside of
the windshield by automatically
sensing the moisture that accumu-
lates on inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.When the Auto Defogging
System operates, the indi-
cator will illuminate.
If a high amount of humidity is
detected in the vehicle, the Auto
Defogging System will be enabled.
The following steps will be performed
automatically:
Step 1 : Outside air position
Step 2 : Operating the air condition-
ing
Step 3 : Blowing air toward the wind-
shield
Step 4 : Increasing air flow toward
the windshield
If the air conditioning is off or recircu-
lated air position is manually select-
ed while Auto Defogging System is
ON, the "ADS OFF" symbol will blink
3 times to signal that the manual
operation has been canceled.
To cancel or reset the
Auto Defogging System
Press the front windshield defroster
button for 3 seconds when the igni-
tion switch is in the ON position.
When the Auto Defogging System is
canceled, the ADS OFF symbol will
blink 3 times and ADS OFF will be
displayed on the climate control
information screen.
When the Auto Defogging System is
reset, the ADS OFF symbol will blink
6 times without a signal.

- Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The FCA system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
Detecting pedestrians
The sensor may be limited when:
The pedestrian is not fully detected
by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very
quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing
that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
The outside lighting is too bright
(e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
It is difficult to detect and distin-
guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
There is an item similar to a per-
son's body structure
The pedestrian is small The pedestrian has impaired
mobility
The radar sensor or camera is
blocked with a foreign object or
debris
The camera lens is contaminated
due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
The brightness outside is too low
such as when the headlamps are
not on at night or the vehicle is
going through a tunnel

rain or snow obscures the field of
view of the radar sensor or camera
When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road

indicator (yellow) will illu-
minate if the LKA system
is not working properly.
Have your vehicle
checked by an authorized
HYUNDAI dealer.
When there is a problem with the
system do one of the following:
Turn the system on after turning
the engine off and on again.
Check if the ignition switch is in the
ON position.
Check if the system is affected by
the weather. (ex: fog, heavy rain,
etc.)
Check if there is foreign matter on
the camera lens.
If the problem is not solved, have
your vehicle checked by an author-
ized HYUNDAI dealer.
The LKA system will not be in the
ENABLED state and/or the steering
wheel will not be assisted when:
The turn signal is turned on before
changing a lane. If you change
lanes without the turn signal on, the
steering wheel might be controlled.
The vehicle is not driven in the mid-
dle of the lane when the system is
turned on or right after changing a
lane.
ESC (Electronic Stability Control) or
VSM (Vehicle Stability Management)
is activated.
The vehicle is driven on a sharp
curve.
Vehicle speed is below 35 mph
(56 km/h) and over 110 mph (177
km/h).
The vehicle makes sharp lane
changes.
The vehicle brakes suddenly.
The lane is very wide or narrow.
There are more than two lane lines
on the road. (e.g. construction area)
Only one side of the lane marker is
detected. Radius of a curve is too small.
The vehicle is driven on a steep
incline.
The steering wheel is turned sud-
denly.
Limitations of the System
The LKA system may operate pre-
maturely even if the vehicle does not
depart from the intended lane, OR,
the LKA system may not warn you if
the vehicle leaves the intended lane
under the following circumstances:
When the lane and road condi-
tions are poor
It is difficult to distinguish the lane
marker from the road because the
lane marker is covered with dust or
sand.
It is difficult to distinguish the color
of the lane marker from the road.
There are markings on the road
surface that look like a lane marker
that is inadvertently being detected
by the camera.
The lane marker is indistinct or
damaged.

When front visibility is poor
The windshield or the camera lens
is blocked with dirt or debris.
The windshield glass is fogged up;
a clear view of the road is obstruct-
ed.
Placing objects on the dashboard,
etc.
The sensor cannot detect the lane
because of fog, heavy rain or snow.LKA System Function Change
The driver can change LKA to Lane
Departure Warning from the LCD
display. Go to the 'User Settings →
Driver Assistance →Lane Safety →
Active LKA/Lane Keeping Assist/
Lane Departure Warning.
Active LKA
The Active LKA mode provides more
frequent steering wheel control in
comparison with the Standard LKA
mode.
Lane Keeping Assist
This mode guides the driver to help
keep the vehicle within the lanes. It
rarely controls the steering wheel,
when the vehicle drives well inside
the lanes. However, it starts to con-
trol the steering wheel, when the
vehicle is about to deviate out of the
lane.
Lane Departure Warning
LDW system alerts the driver with a
visual warning and a warning alarm
when the system detects the vehicle
departing the lane. The steering
wheel will not be controlled.
