Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The AEB provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The AEB brake control is automat- ically canceled, when risk factors
disappear.
AEB Sensor
In order for the AEB system to oper-
ate 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 sensor.
The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the AEB system.
CAUTION
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING
The AEB system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
AEB system.

Driving your vehicle
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 cover clean and free of dirt
and debris.
Use only a soft cloth to wash the vehicle. Do not spray pressur-
ized water directly on the sensor
or sensor cover.
Be careful not to apply unneces- sary force on the radar sensor or
sensor cover. If the sensor is
forcibly moved out of proper
alignment, the AEB system may
not operate correctly. In this
case, a warning message may
not be displayed. Have the vehi-
cle inspected by an authorized
HYUNDAI dealer.
(Continued)(Continued)
If the front bumper becomes
damaged in the area around the
radar sensor, the AEB system
may not operate properly. Have
the vehicle inspected by author-
ized HYUNDAI.
Use only genuine parts to repair or replace a damaged sensor or
sensor cover. Do not apply paint
to the sensor cover. NEVER install any accessories
or stickers on the front wind-
shield, nor tint the front wind-
shield.
NEVER locate any reflective objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a malfunc-
tion of the system.
Pay extreme caution to keep the camera out of water.
NEVER disassemble the camera assembly, nor apply any impact
on the camera assembly.
Playing the vehicle audio sys- tem at high volume may offset
the system warning sounds.
Information
Have the system checked by an
authorized HYUNDAI dealer when:
• The windshield glass is replaced.
• The front bumper is replaced.
• The sensor cover or sensor getsdamaged or replaced.

Warning message and warninglight
Autonomous Emergency Braking
disabled. Radar blocked
When the sensor cover is blocked
with dirt, snow, or debris, the AEB
system operation may stop tem-
porarily. If this occurs, a warning
message will appear on the LCD dis-
play.
Remove any dirt, snow, or debris and
clean the radar sensor cover before
operating the AEB system. The sys-
tem will operate normally when such
dirt, snow or debris is removed. The AEB may not properly operate in
an area (e.g. open terrain), where
any substances are not detected
after turning ON the vehicle.
System Malfunction
Check AEB system
When the AEB is not working prop-
erly, the AEB warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning 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 (Electronic Stability
Control) warning light.

Driving your vehicle(Continued)
Even if there is any problem
with the brake control func-
tion of the AEB system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, brake control
function for avoiding collision
will not activate.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The AEB system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The AEB system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.(Continued)
(Continued)
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
Occupants may get injured, if
the vehicle abruptly stops by
the activated AEB system. Pay
extreme caution.
The AEB system operates
only to help detect vehicles or
pedestrians in front of the
vehicle.
The AEB system does not
operate 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 vehicles in the oppo-
site lane.(Continued)
WARNING
The AEB is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle 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 condi-
tions, the AEB system may
activate unintentionally. This
initial warning message
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 pedestri-
an ahead. The AEB system
may not activate and the
warning message will not be
displayed.(Continued)

Limitations of the System
The Autonomous Emergency Braking
(AEB) system is designed to help
monitor the vehicle ahead or a pedes-
trian in the roadway through radar sig-
nals and camera recognition to warn
the driver that a collision is imminent,
and if necessary, apply emergency
braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the AEB sys-
tem 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 isblocked with 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 electro- magnetic waves There is severe irregular reflection
from the radar sensor
The radar/camera sensor recogni- tion is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
The driver's field of view is not well illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have their rear lights properly turned ON
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
Light coming from a street light or an oncoming vehicle is reflected on
a wet road surface such as a pud-
dle in the road
The field of view in front is obstructed by sun glare
The windshield glass is fogged up; a clear view of the road is obstructed
(Continued)
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 vehi-
cle (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 driv-
ing speed in order to maintain a
safe distance.

5-52
Driving your vehicle
The vehicle in front is driving errat- ically
The vehicle is on unpaved or uneven rough surfaces, or road
with sudden gradient changes.
The vehicle is driven near areas containing metal substances as a
construction zone, railroad, etc.
The vehicle drives inside a build- ing, such as a basement parking
lot
The adverse road conditions cause excessive vehicle vibrations while
driving
The sensor recognition changes suddenly when passing over a
speed bump
The vehicle in front is moving verti- cally to the driving direction
The vehicle in front is stopped ver- tically
The vehicle in front is driving towards your vehicle or reversing - Driving on a curve
The performance of the AEB system
may be limited when driving on a
curved road.
On curved roads, the other vehicle
on the same lane is not recognized
and the AEB system's performance
may be degraded. This may result in
unnecessary alarm or braking or no
alarm or braking when necessary.
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 main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.

The AEB system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Check the surrounding traffic condi-
tions before use.- Driving on a slope
The performance of the AEB decreas-
es while driving upward or downward
on a slope, not recognizing the vehi-
cle in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the AEB suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
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.- Changing lanes
When a vehicle changes lanes in
front of you, the AEB system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
