LKA system failure indicator
The LKA system failure
indicator (yellow) will illu-
minate if the LKA system
is not working properly.
Have your vehicle
checked by an authorized
HYUNDAI dealer.
When there is a problem with the
system do one of the following:
Turn the system on after turning
the engine off and on again.
Check if the ignition switch is in the
ON position.
Check if the system is affected by
the weather. (ex: fog, heavy rain,
etc.)
Check if there is foreign matter on
the camera lens.
If the problem is not solved, have
your vehicle checked by an author-
ized HYUNDAI dealer.
The LKA system will not be in the
ENABLED state and/or the steering
wheel will not be assisted when:
The turn signal is turned on before
changing a lane. If you change
lanes without the turn signal on, the
steering wheel might be controlled.
The vehicle is not driven in the mid-
dle of the lane when the system is
turned on or right after changing a
lane.
ESC (Electronic Stability Control) or
VSM (Vehicle Stability Management)
is activated.
The vehicle is driven on a sharp
curve.
Vehicle speed is below 35 mph
(56 km/h) and over 110 mph (177
km/h).
The vehicle makes sharp lane
changes.
The vehicle brakes suddenly.
The lane is very wide or narrow.
There are more than two lane lines
on the road. (e.g. construction area)
Only one side of the lane marker is
detected. Radius of a curve is too small.
The vehicle is driven on a steep
incline.
The steering wheel is turned sud-
denly.
Limitations of the System
The LKA system may operate pre-
maturely even if the vehicle does not
depart from the intended lane, OR,
the LKA system may not warn you if
the vehicle leaves the intended lane
under the following circumstances:
When the lane and road condi-
tions are poor
It is difficult to distinguish the lane
marker from the road because the
lane marker is covered with dust or
sand.
It is difficult to distinguish the color
of the lane marker from the road.
There are markings on the road
surface that look like a lane marker
that is inadvertently being detected
by the camera.
The lane marker is indistinct or
damaged.

When front visibility is poor
The windshield or the camera lens
is blocked with dirt or debris.
The windshield glass is fogged up;
a clear view of the road is obstruct-
ed.
Placing objects on the dashboard,
etc.
The sensor cannot detect the lane
because of fog, heavy rain or snow.LKA System Function Change
The driver can change LKA to Lane
Departure Warning from the LCD
display. Go to the 'User Settings →
Driver Assistance →Lane Safety →
Active LKA/Lane Keeping Assist/
Lane Departure Warning.
Active LKA
The Active LKA mode provides more
frequent steering wheel control in
comparison with the Standard LKA
mode.
Lane Keeping Assist
This mode guides the driver to help
keep the vehicle within the lanes. It
rarely controls the steering wheel,
when the vehicle drives well inside
the lanes. However, it starts to con-
trol the steering wheel, when the
vehicle is about to deviate out of the
lane.
Lane Departure Warning
LDW system alerts the driver with a
visual warning and a warning alarm
when the system detects the vehicle
departing the lane. The steering
wheel will not be controlled.
Information
This device complies with Part 15 of
the FCC rules.
Operation is subject to the following
two conditions:
1. This device may not cause harmful
interference, and
2. This device must accept any inter-
ference received, including interfer-

Normal:
Vehicle speed following the front
vehicle to maintain the set distance
is normal.
Slow:
Vehicle speed following the front
vehicle to maintain the set distance
is slower than normal speed.
Information
When you select the SCC Reaction
sensitivity in the User Settings menu,
this setting will remain as the default
setting each time you start your vehi-
cle.
Conventional Cruise Control
Mode
The driver may choose to switch to

A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
luggage compartment
- While the steering wheel is operat-
ing
- When driving to one side of the
lane
- When driving on narrow lanes or
on curves
Apply the brake or accelerator pedal
if necessary. Your vehicle may accelerate when
a vehicle ahead of you disappears.
When you are warned that the
vehicle ahead of you is not detect-
ed, drive with caution. When driving in stop-and-go traffic,
and a stopped vehicle in front of
you merges out of the lane, the
system may not immediately
detect the new vehicle that is now
in front of you. In this case, you
must maintain a safe braking dis-
tance, and if necessary, depress
the brake pedal to reduce your
driving speed in order to maintain a
safe distance.

Hazardous driving conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take the
below suggestions:
Drive cautiously and keep a longer
braking distance.
Avoid abrupt braking or steering.
When your vehicle is stuck in snow,
mud, or sand, use second gear.
Accelerate slowly to avoid unnec-
essary wheel spin.
Put sand, rock salt, tire chains or
other non-slip materials under the
wheels to provide additional trac-
tion while the vehicle becomes
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.

Downshifting with an automatic
transmission while driving on
slippery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
WARNING
If the vehicle is stuck and
excessive wheel spin occurs,
the temperature in the tires can
increase very quickly. If the tires
become damaged, a tire blow
out or tire explosion can occur.
This condition is dangerous -
you and others may be injured.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle.
If you attempt to free the vehicle,
the vehicle can overheat quickly,
possibly causing an engine
compartment fire or other dam-
age. Try to avoid spinning the
wheels as much as possible to
prevent overheating of either the
tires or the engine. DO NOT
allow the vehicle to spin the
wheels above 35 mph (56 km/h).
WARNING

5-124
Driving your vehicle
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 decreas-
es, refer to "Tire replacement" 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.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
