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.

Your vehicle's fuel economy depends
mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos- sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 8. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 8 for details).
Keep your vehicle clean. For maxi- mum service, your vehicle should
be kept clean and free of corrosive
materials. It is especially important
that mud, dirt, ice, etc. not be
allowed to accumulate on the
underside of the vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.
ECONOMICAL OPERATION

5131
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.

5133
Driving your vehicle
The ESC system should be turned
OFF prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration. If
you follow these suggestions, tire
wear will be held to a minimum.
Driving at night
Because night driving presents more
hazards than driving in the daylight,
here are some important tips to
remember:
Slow down and keep more dis-tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
CAUTION- Vehicle rocking
Prolonged rocking may causeengine overheating, transmis-sion damage or failure, and tiredamage.
CAUTION- Spinning tires
Do not spin the wheels, espe-cially at speeds more than 56km/h (35 mph). Spinning thewheels at high speeds when thevehicle is stationary couldcause a tire to overheat whichcould result in tire damage thatmay injure bystanders.

Driving your vehicle
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
affected.
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 pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING- Under/overinflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
WARNING- Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out tires
should be replaced as soon as
possible. For further information
and tread limits, refer to "Tires
and wheels" in chapter 8.

Severe weather conditions in the
winter result in greater wear and
other problems. To reduce the prob-
lems of winter driving, you should fol-
low these suggestions:Snowy or icy conditions
To drive your vehicle in deep snow, it
may be necessary to use snow tires
on your tires. If snow tires are need-
ed, it is necessary to select tires
equivalent in size and type of the
original equipment tires. Failure to do
so may adversely affect the safety
and handling of your vehicle.
Furthermore, speeding, rapid accel-
eration, 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. You
need to keep sufficient distance
between the vehicle in operation in
front of your vehicle. Also, apply the
brake gently.
Snow tires
If you mount snow tires on your vehi-
cle, make sure they are 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.
Keep in mind that the traction provid-
ed by snow tires on dry roads may
not be as high as your vehicle's orig-
inal equipment tires. You should drive
cautiously even when the roads are
clear. Check with the tire dealer for
maximum speed recommendations.
Do not install studded tires without
first checking local, state and munic-ipal regulations for possible restric-tions against their use.
WINTER DRIVING
WARNING - Snow tire size
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your vehi-
cle may be adversely affected.
