The Automatic Emergency Braking
(AEB) system is designed to detect and
monitor the vehicle ahead or detect a
pedestrian in the roadway through radar
signals and camera recognition to warn
the driver that a collision is imminent, and
if necessary, apply emergency braking.System Setting and Activation
System setting
The driver can activate the AEB by plac-
ing the ignition switch to the ON position
and by selecting 'User Settings', 'Driving
Assist', and 'AEB (Automatic Braking
System)'. The AEB deactivates, when the
driver deselects the system setting.The warning light illuminates
on the LCD display, when you
cancel the AEB system. The
driver can monitor the AEB
ON/OFF status on the LCD display. If the
warning light remains ON when the AEB
is activated, have the system checked by
an authorized HYUNDAI dealer. The driver can select the initial warning
activation time in the User Settings in the
LCD display. The options for the initial
Forward Collision Warning include the
following:
Early - When this condition is selected,
the initial Forward Collision
Warning is activated earlier than
normal. This setting maximizes
the amount of distance between
the vehicle ahead before the ini-
tial warning occurs.

Take the following precautions
when using the Automatic
Emergency Braking (AEB):
This system is only a supplemen-
tal system and it is not intended
to, nor does it replace the need
for extreme care and attention of
the driver. The sensing range and
objects detectable by the sensors
are limited. Pay attention to the
road conditions at all times.
NEVER drive too fast in accor-
dance with the road conditions or
while cornering.
Always drive cautiously to pre-
vent unexpected and sudden sit-
uations from occurring. AEB
does not stop the vehicle com-
pletely and is not a collision
avoidance system.

AEB Front Radar Sensor
In order for the AEB system to operate
properly, always make sure the radar
sensor cover is clean and free of dirt,
snow, and debris. Dirt, snow, or foreign
substances on the lens may adversely
affect the sensing performance of the
radar.
Warning message and warninglight
When the sensor cover is blocked with
dirt, snow, or debris, the AEB system
operation may stop temporarily. If this
occurs, a warning message will appear
on the LCD display. Remove any dirt,
snow, or debris and clean the radar sen-
sor cover before operating the AEB sys-
tem.
The AEB may not properly operate in an
area (e.g. open terrain), where any sub-
stances are not detected after turning
ON the engine. Do not apply 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 sen-
sor 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, the
AEB system may not operate cor-
rectly. In this case, a warning mes-
sage may not be displayed. Have the
vehicle inspected by an authorized
HYUNDAI dealer.
If the front bumper becomes dam- aged in the area around the radar
sensor, the AEB 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.

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.
(Continued)
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.

- The vehicle in front is driving erratical-ly.
- The vehicle drives through a construc- tion area, on an unpaved road, or
above metal materials, such as a rail-
way.
- The vehicle drives inside a building, such as a basement parking lot.
- Driving on a curve
The performance of the AEB system may
be limited when driving on a curved road.
In certain instances on a curved road,
the AEB system may activate premature-
ly.
Also, in certain instances the front radar
sensor or camera recognition system
may not detect the vehicle traveling on a
curved road.
In these cases, the driver must maintain
a safe braking distance, and if necessary,
depress the brake pedal to reduce your
driving speed in order to maintain a safe
distance. - Driving on a slope
The performance of the AEB decreases
while driving upward or downward on a
slope, not recognizing the vehicle in front
in the same lane. It may unnecessarily
produce the warning message and the
warning alarm, or it may not produce the
warning message and the warning alarm
at all.
When the AEB suddenly recognizes the
vehicle in front while passing over a
slope, you may experience sharp decel-
eration.
Always keep your eyes forward while
driving upward or downward on a slope,
and, if necessary, 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 bythe 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 background,
making it difficult to be detected by the
camera recognition 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 distinguish the pedestrian from other objects in the
surroundings, for example, when there
is a group of pedestrians or a large
crowd.Information
In some instances, the AEB system may be
cancelled when subjected to electromag-
netic interference.
Information
This device complies with Part 15 of the
FCC rules.
Operation is subject to the following two
conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interfer- ence received, including interference

Do not use the Automatic
Emergency Braking system when
towing a vehicle. Application of
the AEB system while towing
may adversely affect the safety of
your vehicle or the towing vehi-
cle.
Use extreme caution when 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 clear-
ance.
The AEB system is designed to
detect and monitor the vehicle
ahead or detect a pedestrian in
the roadway through radar sig-
nals and camera recognition. It is
not designed to detect bicycles,
motorcycles, or smaller wheeled
objects such as luggage bags,
shopping carts, or strollers.
Never try to test the operation of
the AEB system. Doing so may
cause severe injury or death.
