km/h (37 mph).
- 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 60 km/h (37 mph)
and all the activation conditions are
satisfied, a green steering wheel
indicator will illuminate and the
system will provide steering inputs.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.

Driving your vehicle
If the speed of the vehicle is over 60
km/h (37 mph) 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 64 km/h(40 mph).
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 are not satisfied, the system will
convert to the Lane Departure
Warning (LDW) system and warn
the driver only when the driver
crosses the lane markers. 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 providing steering
inputs.
✽ ✽
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. WARNING
Always have your hands on the
steering wheel while driving
If you hold the steering wheel with a light grip, the system
may generate a hands off
warning.
WARNING
It is the responsibility of thedriver to safely steer the vehi-
cle and to maintain it in its lane.
Even though the steering is assisted by the system, the
driver may control the steer-
ing wheel.
Turn off the LKA system and drive without using the sys-
tem in the following situa-
tions:
- In bad weather
- In bad road conditions
- When the steering wheelneeds to be controlled by the
driver frequently.
The steering wheel may feel heavier when the steering
wheel is assisted by the sys-
tem than when it is not.

5121
Driving your vehicle
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 cannot
assist steering if the vehicle follows
a lane marker too closely.
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 60
km/h (37 mph) and over 177 km/h
(110 mph). 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 on a steep slope or hill.DRIVER’S ATTENTION
The driver must be cautious in the
following situations because the sys-
tem may be limited when recogni-
tion of the lane marker is poor or
limited :
  When lane and road condition is
poor
• It is difficult to distinguish the lane marker from road when the lane
marker is covered with dust or
sand.
• It is difficult to distinguish the color of the lane marker from
road.
• There is something that resembles a lane marker.
• The lane marker is indistinct or damaged.
• The number of lanes increases/ decreases or the lane lines are
crossing (Driving through a toll
plaza/toll gate, merged/divided
lane). (Continued)

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 system will not
provide steering inputs when the
vehicle’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 provides steering inputs
when the vehicle is about to deviate
from the lanes.
Active LKA
The active LKA mode provides more
frequent steering inputs in compari-
son with the Standard LKA mode.

Driving your vehicle
Remember, your vehicle does notrequire 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.
Opening 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 engine start/stop
button while driving could
engage the steering 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 extra
distance 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 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 possi-
ble damage to the transmission.
SPECIAL DRIVING CONDITIONS
WARNING- Downshifting
Do not downshift with an auto-
matic transmission while driv-
ing 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.

Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 8 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.
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 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.

What to do in an emergency
Introduction
With the Tire Mobility Kit (TMK) you
can stay mobile even after experi-
encing certain tire punctures.
The system compressor and sealing
compound effectively seal most
punctures in a passenger car tire
caused by nails or similar objects
and reinflate the tire.
After you ensure that the tire is prop-
erly sealed, you can drive cautiously
on the tire at a max. speed of 80
km/h (50 mph) in order to reach a
vehicle or tire dealer to have the tire
replaced as soon as.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 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
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.
