Emergency braking (3rdwarning)
This warning message appears on
the LCD display with a warning
alarm.
Additionally, automatic emergency braking of the vehicle is applied in
order to avoid a collision.
- If your vehicle is traveling lessthan 40 mph (65 km/h) and a
pedestrian is detected within the
Emergency Braking stage, auto-
matic emergency braking of the
vehicle is applied. In this condi-
tion, your vehicle speed will
decelerate sharply to avoid a col-
lision. - When your vehicle drives slower
than 40 mph (65 km/h) with a
passer-by in front, the driving
speed may abruptly decrease.
When your vehicle drives faster
than 40 mph (65 km/h) with a
pedestrian in front, the AEB does
not operate.
Brake operation
In an urgent situation, the braking system 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 depress-
es the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the brake pedal,
or when the driver abruptly oper-
ates the steering wheel.
The braking control is automatical- ly canceled, when risk factors dis-
appear.
OLF056451N
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.

AEB front radar sensor
In order for the AEB system to oper-
ate properly, always make sure the
radar sensor lens cover is clean and
free of dirt, snow, and debris. Dirt,
snow, or foreign substances on the
lens may adversely affect the sens-
ing performance of the radar.
Warning message and warninglight
When the sensor lens 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 dis-
play. Remove any dirt, snow, or
debris and clean the radar sensor
lens cover before operating the AEB
system.
OLF054032N
OLF056453NThe 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.
WARNING
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.

Do not apply foreign objectssuch 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 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. 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 an
authorized HYUNDAI dealer.
Use only genuine HYUNDAI parts to repair or replace a dam-
aged sensor or sensor cover. Do
not apply paint to the sensor
cover.
System malfunction
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 warning light.

Driving your vehicle
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 prematurely. This ini-
tial 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)
(Continued)
If there is a malfunction with
the AEB system, the automat-
ic emergency braking is not
applied even though the brak-
ing system is operating nor-
mally.
The AEB system operates
only to 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 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.)
(Continued)
(Continued)In these cases, you must
maintain a safe braking dis-
tance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis-
tance.WARNING

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 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 vehicle in front is too small to be detected by the camera recog-
nition system (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
- The vehicle in front is driving errat- ically

5-90
Driving your vehicle
- 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
prematurely.
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. - Driving on a slope
The performance of the AEB
decreases while driving upward or
downward on a slope, not recogniz-
ing the vehicle in front in the same
lane. It may unnecessarily produce
the warning message and the warn-
ing 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 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.When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the AEB sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
- 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 AEB 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 detectedby 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 crowdInformation
In some instances, the AEB system
may be cancelled when subjected to
electromagnetic interference.
