System Malfunction
When the AEB is not working properly,the AEB warning light ( ) will illumi-
nate and the warning message will
appear for a few seconds. After the
message disappears, the master warn-
ing light ( ) will illuminate. In this
case, have the vehicle inspected by an
authorized HYUNDAI dealer.
The AEB warning message may appear along with the illumination of
the ESC warning light.

The AEB is only a supplemental
system for the driver’s conven-
ience. The driver should hold the
responsibility to control the vehi-
cle operation. Do not solely
depend on the AEB system.
Rather, maintain a safe braking
distance, and, if necessary,
depress the brake pedal to
reduce the driving speed.
In certain instances and under
certain driving conditions, the
AEB system may activate prema-
turely. This initial warning mes-
sage appears on the LCD display
with a warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestrian
ahead. The AEB system may not
activate and the warning mes-
sage will not be displayed.

WARNING (Continued)
If there is a malfunction with the
AEB system, the automatic emer-
gency braking is not applied even
though the braking system is
operating normally.
The AEB system operates only to
detect vehicles or pedestrians in
front of the vehicle.
The AEB system does not oper-
ate when the vehicle is in reverse.
The AEB system is not designed
to detect other objects on the
road such as animals.
The AEB system does not detect
cross traffic vehicles that are
approaching.
The AEB system cannot detect
the driver approaching the side
view of a parked vehicle (for
example on a dead end street.)
In these cases, you must main-
tain a safe braking distance, and
if necessary, depress the brake
pedal to reduce the driving speed
in order to maintain a safe dis-
tance.(Continued)

Limitations of the System
The Automatic Emergency Braking
(AEB) system is designed to monitor the
vehicle ahead or a pedestrian in the
roadway through radar signals and cam-
era recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
In certain situations, the radar sensor or
the camera may not be able to detect the
vehicle or pedestrian ahead. In these
cases, the AEB system may not operate
normally. The driver must pay careful
attention in the following situations where
the AEB operation may be limited.
Detecting vehicles
The sensor may be limited when:
- The radar sensor or camera is blockedwith a foreign object or debris.
- Inclement weather such as heavy rain or snow obscures the field of view of
the radar sensor or camera.
- There is interference by electromag- netic waves.
- There is severe irregular reflection from the radar sensor.
- The vehicle in front is too small to be detected by the camera recognition
system (for example a motorcycle or a
bicycle, etc.).
- The vehicle in front is an oversize vehi- cle or trailer that is too big to be detect-
ed by the camera recognition system
(for example a tractor trailer, etc.).
- The driver's field of view is not well illu- minated (either too dark or too much
reflection or too much backlight that
obscures the field of view).
- The vehicle in front does not have their rear lights properly turned ON.
- The outside brightness changes sud- denly, for example when entering or
exiting a tunnel.
(Continued)The brake control may be insuffi-
cient, possibly causing a colli-
sion, if a vehicle in front abruptly
stops. Always pay extreme cau-
tion.
Occupants may get injured, if the
vehicle abruptly stops by the acti-
vated AEB system. Pay extreme
caution.

Driving your vehicle
The LKAS system will not be in the
ENABLED state and the steering
wheel will not be assisted when:
Vehicle speed is below 40 mph (60 km/h) and over 110 mph (180
km/h).
Only one lane line is detected.
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 hazard warning flasher is on.
The width of the lane is below 10 feet (3.1 m) and over 15 feet (4.5
m).
ESC (Electronic Stability Control) is activated.
The vehicle is driven on a sharp curve.
The vehicle brakes suddenly.
The vehicle makes sharp lane changes.
Information
When the system is turned on or right
after changing a lane, drive in the middle
of the lane. If not, the system will not pro-
vide steering assist function.
Limitations of the System
The LKAS may operate prematurely
even if the vehicle does not depart from
the intended lane, OR, the LKAS may not
warn you if the vehicle leaves the intend-
ed lane under the following circum-
stances:
The lanes ahead are not visible due torain, snow, water on the road, dam-
aged or stained road surface, or other
factors.
The brightness outside changes sud- denly such as when entering or exiting
a tunnel.
The brightness outside is too low such as when the headlamps are not on at
night or the vehicle is going through a
tunnel.
It is difficult to distinguish the lane marking from the road surface or the
lane marking is faded or not clearly
marked.
Driving on a steep grade, over a hill, or when driving on a curved road.
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.
The windshield or the LKAS camera lens is blocked with dirt or debris. The field of view in front is obstructed
by sun glare.
The lanes are incomplete or the area is in a construction zone.
There are more than two lane lines on the road in front of you.
The lane markings are not clearly visi- ble from the road.
The lane width is too wide or too nar- row. See previous page.
The windshield glass is fogged up; a clear view of the road is obstructed.
There are markings on the road sur- face that look like a lane line that is
inadvertently being detected by the
camera.
There is a boundary structure in the roadway such as a concrete barrier,
guardrail and reflector post that is
inadvertently being detected by the
camera.
There is not enough distance between you and the vehicle in front to be able
to detect the lane line or the vehicle
ahead is driving on the lane line.
The adverse road conditions cause excessive vehicle vibrations while driv-
ing.

Driving your vehicle
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage
to the transmission, and tire damage.
See "Towing" in chapter 6.
Smooth Cornering
Avoid braking or gear changing in cor-
ners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at Night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
Slow down and keep more distancebetween you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
Adjust your mirrors to reduce the glare from other driver's headlamps.
Keep your headlamps clean and prop- erly aimed. Dirty or improperly aimed
headlamps will make it much more dif-
ficult to see at night.
Avoid staring directly at the headlamps of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to con-
sider when driving in the rain or on slick
pavement:
Slow down and allow extra followingdistance. A heavy rainfall makes it
harder to see and increases the dis-
tance needed to stop your vehicle.
Turn OFF your Cruise Control.
Replace your windshield wiper blades when they show signs of streaking or
missing areas on the windshield.
Tires should be properly maintained with at least 2/32nds of an inch of tread
depth. If your tires do not have enough
tread, making a quick stop on wet
pavement can cause a skid and possi-
bly lead to an accident. See "Tire
Tread" in chapter 7.
Turn on your headlamps to make it easier for others to see you.
Driving too fast through large puddles can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
If you believe your brakes may be wet, apply them lightly while driving until
normal braking operation returns.
