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.
OLF057032N
OLF057599NThe 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.
(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 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,

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 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 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

5-106
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.

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.
Information

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 vehi-
cle or the towing vehicle
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 clearance.
The AEB system is designed
to help detect and monitor the
vehicle ahead or detect a
pedestrian in the roadway
through radar signals and
camera recognition. It is not
designed to detect bicycles,
motorcycles, or smaller
wheeled objects such as lug-
gage bags, shopping carts, or
strollers.

Hazardous Driving Conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud or sand:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in braking
or steering.
If stuck in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, or other non-slip
material under the drive wheels to
provide traction when stuck in ice,
snow, or mud.
Rocking the Vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and a for-
ward gear.
Try to avoid spinning the wheels, and
do not race the engine.
To prevent transmission wear, wait
until the wheels stop spinning before
shifting gears. Release the accelera-
tor pedal while shifting, and press
lightly on the accelerator pedal while
the transmission is in gear. Slowly
spinning the wheels in forward and
reverse directions causes a rocking
motion that may free the vehicle.If the tires spin at high speed the
tires can explode, and you or oth-
ers may be injured. Do not attempt
this procedure if people or objects
are anywhere near the vehicle.
The vehicle can overheat causing
an engine compartment fire or
other damage. Spin the wheels as
little as possible and avoid spin-
ning the wheels at speeds over 35
mph (56 km/h) as indicated on the
speedometer.

Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without
first checking local, state and munici-
pal regulations for possible restric-
tions against their use.
Tire chains
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them.
Therefore, the use of snow tires is
recommended instead of tire chains.
Do not mount tire chains on vehicles
equipped with aluminum wheels; if
unavoidable use a wire type chain. If
tire chains must be used, use gen-
uine HYUNDAI parts and install the
tire chain after reviewing the instruc-
tions provided with the tire chains.
Damage to your vehicle caused by
improper tire chain use is not cov-
ered by your vehicle manufacturer’s
warranty.
i
Snow tires should be equivalent
in size and type to the vehicle’s
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.

Information
• Install tire chains on the front tires.It should be noted that installing tire
chains on the tires will provide a
greater driving force, but will not
prevent side skids.
• Do not install studded tires without first checking local, state and
municipal regulations for possible
restrictions against their use.
Chain installation
When installing tire chains, follow the
manufacturer's instructions and
mount them as tightly possible. Drive
slowly (less than 20 mph (30 km/h))
with chains installed. If you hear the
chains contacting the body or chas-
sis, stop and tighten them. If they still
make contact, slow down until the
noise stops. Remove the tire chains
as soon as you begin driving on
cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning Flasher and place a
triangular emergency warning device
behind the vehicle (if available).
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing snow
chains.i
The use of tire chains may
adversely affect vehicle han-
dling:
Drive less than 20 mph
(30 km/h) or the chain manu-
facturer's recommended speed
limit, whichever is lower.
Drive carefully and avoid
bumps, holes, sharp turns,
and other road hazards, which
may cause the vehicle to
bounce.
Avoid sharp turns or locked
wheel braking.
