(Continued)
• When you replace the windshield
glass, front view camera or related
parts of the steering, take your
vehicle to an authorized Kia deal-
er and have the system checked to
need a calibration.
• The system detects lane markers and controls the steering wheel by
a front view camera, therefore, if
the lane markers are hard to
detect, the system may not work
properly. Always be cautious when
using the system.
• When the lane markers are hard to detect, please refer to “Driver’s
Attention”.
• Do not remove or damage the related parts of LKA.
• Do not place objects on the crash pad that reflects light such as mir-
rors, white paper, etc. it may cause
malfunction of LKA if the sunlight
is reflected. (Continued)(Continued)
• You may not hear warning sound
of LKA because of the excessive
audio sound.
• If you continue to drive with your hands off the steering wheel, the
LKA will stop controlling the
steering wheel after the hands off
alarm. After then, if you drive
with your hands on the steering
wheel, the control will be activated
again.
• If the vehicle speed is high, steer- ing torque for assistance will not
be enough to keep your vehicle
within the lane. If so, the vehicle
may move out of its lane. Obey
speed limit when using LKA.
• If you attach objects to the steer- ing wheel, the system may not
assist steering.
• If you attach objects to the steer- ing wheel, hands off alarm may
not work properly.LKA operation
To activate/deactivate the LKA:
With the ignition switch in the ON
position, press the LKA button locat-
ed on the instrument panel on the
lower left hand side of the driver.
The indicator in the cluster display
will initially illuminate white.
When the indicator(white) activated
in the previous ignition cycle, the
system turns on without any control.
If you press the LKA button again,
the indicator on the cluster display
will go off.

The color of indicator will change
depend on the condition of LKA.- White : Sensor does not detect the lane marker or vehicle
speed is less than 40 mph
(64 km/h).
- Green : Sensor detects the lane
marker and system is able
to control the steering.LKA activation
To see the LKA screen on the LCD
display in the cluster, Tab to the
ASSIST mode ( ).
For further details, refer to [menu settings] in chapter 4.
After LKA is activated, if both lane markers are detected, vehicle
speed is over 40 mph (64 km/h)
and all the activation conditions are
satisfied, a green steering wheel
indicator will illuminate and the
steering wheel will be controlled.WARNING
The Lane Keeping Assist system
is a system to help prevent the
driver from leaving the lane.
However, the driver should not
solely rely on the system but
always check the road condi-
tions when driving.

If the speed of the vehicle is over 40
mph (64 km/h) and the system
detects lane markers, the color
changes from gray to white
When the conditions below are met,
LKA will be enable to assist steering.
Vehicle speed is above 40 mph (64
km/h).
Both lane markers are detected by LKA.
The vehicle is between the lane markers.
If LKA can assist steering, a green
steering wheel indicator will illumi-
nate.
Warning
If the vehicle leaves a lane, the lane
marker you cross will blink on the
LCD display.
If the vehicle moves out its lane
because steering torque for assis-
tance is not enough, the line indica-
tor will blink. If all the conditions to activate LKA
is not satisfied, the system will con-
vert to LDW and warn the driver
only when the driver crosses the
lane markers. In this scenario, the
LDW system does not provide any
steering inputs into the vehicle for
you. Accordingly, you must take the
necessary steps to maintain con-
trol of the vehicle and keep it with-
in the lanes.

Driving your vehicle
If the driver takes hands off the steer-
ing wheel for several seconds while
the LKA is activated, the system will
warn the driver.If the driver still does not have their
hands on the steering wheel after
several seconds, the system will not
control the steering wheel and warn
the driver only when the driver cross-
es the lane markers.
However, if the driver has their hands
on the steering wheel again, the sys-
tem will start controlling the steering
wheel.
WARNING
Always have your hands on the
steering wheel while driving.
If you hold the steering wheel lightly, the system would gen-
erate hands off warning
because LKA can treat the sit-
uation as you do not grab the
wheel.

NOTICE
• Even though the steering is assist-
ed by the system, the driver may
control the steering.
• The steering wheel may feel heav- ier when the steering wheel is
assisted by the system than when it
is not.
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.
LKA 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. LKA 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 you 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). Always obey all traffic
laws and drive safely.
The steering will not be assisted when you change lanes quickly.
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 LKA will be disabled
temporarily.

Driving your vehicle
When there is a problem with the sys-
tem do one of the following:
Turn the system on after turningthe 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, take your
vehicle to an authorized Kia dealer
and have the system checked.LKA function change
The driver can change LKA to Lane
Departure Warning (LDW) system or
change the LKA mode between
Standard LKA and Active LKA from
the User Settings Mode on the LCD
display. The driver can choose them by plac-
ing the ignition switch to the ON posi-
tion and by selecting ‘User Settings’,
‘Driver Assistance’, and ‘Lane
Safety’.
The system is automatically set to
Standard LKA when your vehicle is
first delivered from the factory.
Lane Departure
LDW 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, LKA issues the
lane departure warning.
Standard LKA
The Standard LKA mode guides the
driver to keep the vehicle within the
lanes. It rarely controls the steering
wheel, when the vehicle drives well
inside the lanes. However, it starts to
control the steering wheel, when the
vehicle is about to deviate from 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.

Remember, your vehicle does not
require extended warm-up. After
the engine has started, allow the
engine to run for 10 to 20 seconds
prior to placing the vehicle in gear.
In very cold weather, however, give
your engine a slightly longer warm-
up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in a
very high gear resulting in engine
bucking. If this happens, shift to a
lower gear. Over-revving is racing
the engine beyond its safe limit.
This can be avoided by shifting at
the recommended speed. Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset
some of this loss, slow down when
driving in these conditions.
Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized Kia dealer perform
scheduled inspections and mainte-
nance.
WARNING - Engine off
during motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without
the engine running. In addition,
turning off the ignition while
driving could engage the steer-
ing wheel lock resulting in loss
of vehicle steering. Keep the
engine on and downshift to an
appropriate gear for an engine
braking effect.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extradistance for braking.
Avoid sudden braking or steering.
When braking with non-ABS brakes pump the brake pedal with
a light up-and-down motion until
the vehicle is stopped.
Do not pump the brake pedal on a
vehicle equipped with ABS. If stalled in snow, mud, or sand,
use the 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
stalled 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 any
forward gear in vehicles equipped
with an Automatic Transaxle / Dual
clutch transmission. Do not race the
engine, and spin the wheels as little
as possible. If you are still stuck after
a few tries, have the vehicle pulled
out by a tow vehicle to avoid engine
overheating and possible damage to
the transaxle.
SPECIAL DRIVING CONDITIONS
WARNING- Downshifting
Do not downshift with an auto-
matic transaxle while driving on
slippery surfaces. The sudden
change in tire speed could
cause the tires to skid and
result in an accident.
WARNING- Sudden
Vehicle Movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as it
becomes unstuck.

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.
Use approved window washer
anti-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 Kia dealer and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Don’t let your parking brake
freeze
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 shift lever in P
(Park, Automatic Transaxle / Dual
clutch transmission) and block the
rear wheels so the vehicle cannot
roll. Then release the parking brake.
Don't 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
vehicle to be sure the movement of
the front wheels and the steering
components are not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tow straps or chains, flash-
light, emergency flares, sand, shov-
el, jumper cables, window scraper,
gloves, ground cloth, coveralls, blan-
ket, etc.
TRAILER TOWING
We do not recommend using this
vehicle for trailer towing.

What to do in an emergency
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.
Read the section "Notes on the safe
use of the Tire Mobility Kit".Notes on the safe use of the
Tire Mobility Kit
Park your car at the side of theroad 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
Mobility 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 in (6 mm).
Please contact the nearest Kia
dealership if the tire cannot be
made roadworthy with the Tire
Mobility Kit.
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 min. at a time
or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below -22°F
(-30°C).
