LKAS function change Lane Departure Warning
LDWS alerts the driver with a visual
and acoustic warning when the sys-
tem detects the vehicle leaving the
lane. In this mode, the steering wheel
will not be controlled. When the vehi-
cle’s front wheel contacts the inside
edge of lane line, LKAS issues the
lane departure warning.
Standard LKA
The Standard LKA mode guides the
driver to help keep the vehicle within
the lanes. It rarely controls the steer-
ing wheel, when the vehicle drives
well inside the lanes. However, it
starts to control the steering wheel,
when the vehicle is about to deviate
out of the lanes.
Active LKA
The active LKA mode provides more
frequent steering wheel control in
comparison with the Standard LKA
mode. Active LKA can reduce the dri-
ver’s fatigue to assist the steering for
maintaining the vehicle in the middle
of the lane.
5The driver can change LKAS to Lane Departure Warning System (LDWS) or
the LKAS mode between Standard LKA and Active LKA from the User
Settings Mode on the LCD display.

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.
OLF057584N
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.

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.
Never try to test the operation
of the AEB system. Doing so
may cause severe injury or
death.

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.

Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
Slow down and allow extra follow-ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
Turn OFF your Cruise Control. (if equipped)
Replace your windshield wiper blades when they show signs of
streaking or missing areas on the
windshield.
Be sure your tires have enough tread. If your tires do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
Refer to "Tire Tread" in chapter 7.
Turn on your headlamps to make it easier for others to see you.
Driving too fast through large pud- dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly. If you believe your brakes may be
wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet. The
risk of hydroplaning increases as the
depth of tire tread decreases. (Refer
to "Tire Tread" in chapter 7.)
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.

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.
