The system will be cancelled when:
You change lanes with the turn sig-nal.
- Using the turn signal to changelanes.
- If you change lanes without the turn signal on, the steering wheel
might be controlled.
LKAS can transit to steering assist mode when the car is near to mid-
dle of the lane after system on or
the lane was changed. LKAS can
not assist steering if the vehicle fol-
lows lane marker too close contin-
uously before transition to steering
assist mode.
The control of ESC (Electronic Stability Control) or VSM (Vehicle
Stability Management) is activated.
The steering will not be assisted when your drive fast on a sharp
curve.
The steering will not be assisted when vehicle speed is below 40
mph (64 km/h) and over 110 mph
(177 km/h).
The steering will not be assisted when you change lanes fast. The steering will not be assisted
when you brake suddenly.
The steering will not be assisted when the lane is very wide or nar-
row.
The steering will not be assisted when only one side lane marker is
detected.
There are more than two lane markers such as a construction
area.
Radius of a curve is too small.
When you turn steering wheel sud- denly, the LKAS will be disabled

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.

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.

Check spark plugs and ignitionsystem
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
Use approved window washeranti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.
Do not let your parking brakefreeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear selector lever in P
and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not let ice and snow accu-mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects ormaterials in the engine com-partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

It is possible that some tires, espe-
cially with larger punctures or dam-
age to the sidewall, cannot be sealed
completely.
Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle
is heavily loaded or if a trailer is in
use.
The Tire Mobility Kit is not designed
or intended as a permanent tire
repair method and is to be used for
one tire only.
This instruction shows you step by
step how to temporarily seal the
puncture simply and reliably.
Read the section "Notes on the safe
use of the Tire Mobility Kit".Notes on the safe use of theTire Mobility Kit
Park your car at the side of the
road so that you can work with the
Tire Mobility Kit away from moving
traffic.
To be sure your vehicle will not move, even when you’re on fairly
level ground, always set your park-
ing brake.
Only use the Tire Mobility Kit for sealing/inflation passenger car
tires. Only punctured areas located
within the tread region of the tire
can be sealed using the tire mobil-
ity kit.
Do not use on motorcycles, bicy- cles or any other type of tires.
When the tire and wheel are dam- aged, do not use Tire Mobility Kit
for your safety.
Use of the Tire Mobility Kit may not be effective for tire damage larger
than approximately 0.24 inch (6
mm).
Please contact the nearest
HYUNDAI dealership if the tire
cannot be made roadworthy with
the Tire Mobility Kit. Do not use the Tire Mobility Kit if a
tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit unattended while it is being used.
Do not leave the compressor run- ning for more than 10 minutes at a
time or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below
-22°F (-30°C).

Introduction
With the Tire Mobility Kit you stay
mobile even after experiencing a tire
puncture.
The system of compressor and seal-
ing compound effectively and com-
fortably seals most punctures in a
passenger car tire caused by nails
or similar objects and reinflates the
tire.
After you ensured that the tire is
properly sealed you can drive cau-
tiously on the tire (distance up to 200
km (120 miles)) at a max. speed of
80 km/h (50 mph) in order to reach a
service station or tire dealer to have
the tire replaced.
It is possible that some tires, espe-
cially with larger punctures or dam-
age to the sidewall, cannot be sealed
completely.
Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle
is heavily loaded or if a trailer is in
use.The Tire Mobility Kit is not designed
or intended as a permanent tire
repair method and is to be used for
one tire only. This instruction shows
you step by step how to temporarily
seal the puncture simply and reliably.
Read the section "Notes on the safe
use of the Tire Mobility Kit".
What to do in an emergency
Do not use the Tire Mobility Kit
to repair punctures in the tire
walls. This can result in an acci-
dent due to tire failure.
WARNING
Have your tire repaired as soon
as possible. The tire may loose
air pressure at any time after
inflating with the Tire Mobility Kit.
WARNING
When two or more tires are flat,
do not use the tire mobility kit
because the supported one
sealant of Tire Mobility Kit is
only used for one flat tire.
CAUTION
Do not use the TMK if a tire is
severely damaged by driving run
flat or with insufficient air pres-
sure.
Only punctured areas located
within the tread region of the tire
can be sealed using the TMK.
