The system may not work prop-erly when the bumper has been
damaged, or if the rear bumperhas been replaced or repaired.
The sensing range differs some- what according to the width of
the road. When the road is nar-
row, the system may detect
other vehicles in the next lane.
The system may turn off due to strong electromagnetic waves.
Non-operating condition
The BSD indicator on the outer side
view mirror may not illuminate
properly when:
The outside rearview mirror hous-ing is damaged.
The mirror is covered with dirt, snow, or debris.
The window is covered with dirt, snow, or debris.
The window is tinted.
Limitations of the system
The driver must be cautious in the
below situations, because the sys-
tem may not detect other vehicles or
objects in certain circumstances.
The vehicle drives on a curved road or through a tollgate.
The sensor is polluted with rain, snow, mud, etc.
The rear bumper where the sensor is located is covered with a foreign
object such as a bumper sticker, a
bumper guard, a bike rack, etc.
The rear bumper is damaged, or the sensor is out of the original
default position.
The vehicle height gets lower or higher due to heavy loading in the
luggage compartment, abnormal
tire pressure, etc.
The vehicle drives in inclement weather such as heavy rain or
snow.
There is a fixed object near the vehicle, such as a guardrail.

Driving your vehicle
The Autonomous Emergency Braking (AEB) system is designed to detect
and monitor the vehicle ahead or
detect a pedestrian (if equipped) in the
roadway through radar signals and
camera recognition to warn the driverthat a collision is imminent, and if nec-
essary, apply emergency braking.System setting and activation
System setting
The driver can activate the AEB by
placing the ignition switch to the ON
position and by selecting: Cluster type A'User Settings Driving Assist
Forward Collision Warning
Autonomous Emergency Braking'Cluster type B'User Settings Driving Assist
Autonomous Emergency Braking'
The AEB deactivates, when the driv- er cancels the system setting.

Take the following precautions
when using the Autonomous
Emergency Braking (AEB):
This system is only a supple- mental system and it is not
intended to, nor does it
replace the need for extremecare and attention of the driv-
er. The sensing range and
objects detectable by the sen-
sors are limited. Pay attention
to the road conditions at alltimes.
NEVER drive too fast in accor-
dance with the road condi-tions or while cornering.
Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. AEB does not stop the
vehicle completely and is not
a collision avoidance system.
WARNING
■Type A■Type B
OAE056095L/OAE056022L

5-48The warning light illumi-
nates 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 lightremains ON when the AEB is acti-
vated, we recommend you to have
the system checked by an authorized
HYUNDAI dealer.
The driver can select the initial warn-
ing activation time on the LCD display. Go to the 'User Settings Driving
Assist Forward Collision Warning
Late/Normal/Early'.
The options for the initial Forward
Collision Warning includes the fol-
lowing:
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 or pedestrian ahead before
the initial warning occurs. Normal:
When this condition is selected,the initial Forward Collision
Warning is activated normally. This
setting allows for a nominal
amount of distance between the
vehicle or pedestrian ahead before
the initial warning occurs.
Late: When this condition is selected,the initial Forward Collision
Warning is activated later than nor-
mal. This setting reduces the
amount of distance between the
vehicle or pedestrian ahead before
the initial warning occurs.

Prerequisite for activation
The AEB gets ready to be activated, when the AEB is selected on the
LCD display, and when the followingprerequisites are satisfied.
- The ESC (Electronic StabilityControl) is activated.
- To enable the system to detect pedestrians ahead, the vehicle
driving speed must be between 8km/h – 70 km/h (5 mph – 45 mph).
- To enable the system to detect a vehicle ahead, the vehicle driving
speed must be between 8 km/h –180 km/h (5 mph – 110 mph).
When traveling above 80 km/h (50mph), the AEB system only initiates
partial braking. This is to prevent
unintended full braking to stop in the
middle of the highway.
AEB warning message and
system control
The AEB produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.
5
Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate
/deactivate the AEB system.
The AEB automatically acti-
vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the AEB by cancelingthe system setting on the LCD
display.
The AEB automatically deacti-
vates upon canceling the ESC
(Electronic Stability Control).When the ESC is canceled,
the AEB cannot be activated
on the LCD display.
WARNING

5-50
Forward Warning (1stwarning)
This initial warning message appears
on the LCD display with a warning
chime.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward Collision
Warning include Early, Normal or Late
initial warning time.
Collision Warning (2ndwarning)
This warning message appears on the
LCD display with a warning chime.
Additionally, some vehicle system
intervention occurs by the enginemanagement system to help decel-
erate the vehicle.- If a vehicle is detected, your vehi-cle speed may decelerate moder-
ately.
- If your vehicle is traveling less than 70 km/h (45 mph) and a pedestri-an is detected within the Collision
Warning (2nd warning) stage, your
vehicle speed may decelerate
moderately. When your vehicle
drives faster than 70 km/h (45
mph) with a pedestrian in front, the
AEB does not operate.
Emergency braking
(3rdwarning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs by the enginemanagement system to help decel-
erate the vehicle.
- If the detected vehicle in front isdriving slower than 80 km/h (50
mph) your vehicle speed may
decelerate sharply to avoid a col-
lision. If the detected vehicle in
front is driving faster than 80
km/h (50 mph), your vehicle
speed may decelerate moderate-
ly.

Driving your vehicle
- If your vehicle drives slower than70 km/h (45 mph) with a pedestri-
an in front, the driving speed may
abruptly decrease. When your
vehicle drives faster than 70 km/h
(45 mph) 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
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.
5
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 drivershould hold the responsibility
to safely drive and control the
vehicle.
WARNING

5-52
AEB front radar 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 radar.
Warning message and warninglight
Auto 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 warningmessage 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 AEB may not properly operate in
an area (e.g. open terrain), where
any substances are not detected
after turning ON the engine.
Driving your vehicle
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 theAEB system.
