Driving your vehicle
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
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.

Do not apply license plate frameor 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 arbitrarily 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 radar sensor or cover gets dam-aged or replaced.

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
unintentionally activate. 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)
If there is a malfunction with the
AEB system, the autonomous
emergency braking is not
applied even though the brak-
ing system is operating normal-
ly.
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.
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.(Continued)
(Continued)
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.
The AEB system does not
detect cross traffic vehicles
that are approaching.(Continued)
(Continued)
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.

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
The vehicle in front is driving errat- ically
The vehicle is on unpaved or uneven rough surfaces, or roads
with sudden gradient changes
The adverse road conditions cause excessive vehicle vibrations while
driving
The vehicle is moving under ground level or inside a building
The vehicle is driven near areas containing metal substances such
as a construction zone, railroad,
etc.

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.
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. 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 your vehicle
- 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.
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 (if equipped)
The sensor may be limited when:
The pedestrian is not fully detected
by 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
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 crowd
There is an item similar to a per- son’s body structure
The pedestrian is small
The pedestrian has impaired mobility
The sensor recognition is limited The radar sensor or camera is
blocked 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
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)
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 field of view in front is obstructed by sun glare
The windshield glass is fogged up; a clear view of the road is obstruct-
ed
The adverse road conditions cause excessive vehicle vibrations while
driving

The Lane Keeping Assist System
helps detect lane markers on the
road with a camera at the front wind-
shield, and assists the driver's steer-
ing to help keep the vehicle between
lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-
ing, while applying a slight counter-
steering torque, to try to prevent the
vehicle from moving out of its lane.

The lane keeping assist system
is not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is the
responsibility of the driver to
always be aware of the sur-
rounding and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist System (LKAS):
Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
LKAS helps to prevent the driv-
er from moving out of the lane
unintentionally by assisting the
driver's steering. However, the
driver should not solely rely on
the system but always pay
attention on the steering wheel
to stay in the lane.
(Continued)
WARNING
(Continued)
The operation of the LKAS
can be canceled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
Do not disassemble the LKAS
camera temporarily to tint the
window or attach any types of
coatings and accessories. If
you disassemble the camera
and assemble it again, take
your vehicle to an authorized
HYUNDAI dealer and have the
system checked for calibra-
tion.
When you replace the wind-
shield glass, LKAS camera or
related parts of the steering
wheel, take your vehicle to an
authorized HYUNDAI dealer
and have the system checked
for calibration.(Continued)
