Driving your vehicle
The system detects lane markersand controls the steering wheel by
a camera, therefore, if the lane
markers are hard to detect, the
system may not work properly.
Please refer to "Driver's Attention".
Do not remove any LKAS parts or apply impact.
Do not place objects on the dash- board that reflects light such as
mirrors, white paper, etc. The sys-
tem may malfunction if the sunlight
is reflected.
Loud audio sounds may interfere with the passenger from hearing
warning chimes.
Always have your hands on the steering wheel while the LKAS sys-
tem is activated. If you continue to
drive with your hands off the steering
wheel after the "Hand on" warning,
the system will not control steering
automatically. When system does
not control steering automatically, if
you hold steering wheel, system will
control steering automatically

LKAS activation
The LKAS screen will appear on
the LCD display if the system is
activated.
When both lanes are detected and all the conditions to activate the
LKAS are satisfied, the steering
wheel will be controlled (green
steering wheel indicator will illumi-
nate). If the system detects a lane, the
color changes from black to white.
If the system detects the left lane, the left lane color will change from
black to white.
If the system detects the right lane, the right lane color will change
from black to white.
Both lanes must be detected for the system to fully activate.
If only one of the lane is detected, the system will warn (warning beep
and blinking yellow lane) the driver
when the driver crosses the detect-
ed lane.

WARNING
The Lane Keeping Assist
System is a supplemental sys-
tem to prevent the driver from
leaving the lane. However, the
driver should not solely rely on
the system but always check the
road conditions when driving.

Warning
If you cross a lane, the lane youcross will blink (yellow) and symbol
will blink green on LCD with an
audible warning during max 3 sec-
onds.
If the steering wheel appears, the system will control the vehicle’s
steering to prevent the vehicle from
crossing the lane. If all the conditions to activate
LKAS are not satisfied, the system
will convert to LDWS and warn the
driver only when the driver crosses
the lane markers. If the driver takes one’s hands off
the steering wheel while the LKAS
is activated, the system will warn
the driver after several seconds
with a visual and audible warning.
✽ ✽ NOTICE
The warning message may appear
late according to road conditions.
Therefore, always have your hands
on the steering wheel while driving.

LKAS function change
The driver can change LKAS to Lane
Departure Warning System (LDWS)
or change the LKAS mode between
Standard LKA and Active LKA by
selecting 'User Settings', 'Driving
Assist', and ‘Lane Keeping Assist
System’ on the LCD display. The sys-
tem is automatically set to Standard
LKA.
Lane Departure Warning (LDWS)
The system can be converted toLKA to LDW at the User setting
mode.
Refer to User setting in section 4.
LDWS alerts the driver with a visu- al and audible warning when the
system detects the vehicle straying
from its lane.
If the LDWS is operating the indi- cator green/white will illuminate.
The steering wheel will not be con- trolled.
Standard LKA
LKAS only starts intervention whenthe vehicle is predicted to cross the
line.
It's useful to a driver who dislikes frequent intervention by LKAS
LDW is generated when the vehi- cle is about to cross the line.
Active LKA
LKAS operates for a vehicle tokeep the region of lane center
more efficiently.
The steering assistance is activat- ed more frequently and earlier than
standard LKA.
LDW is generated when the vehi- cle is about to cross the line.

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 kilometers (miles) you can get
from a liter (gallon) 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
section 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see sec-
tion 7 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

583
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.
Open windows at high speeds can reduce fuel economy.
Fuel economy is reduced by cross- winds and headwinds. To help off-
set 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 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 second gear. Accelerate slow-
ly 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 1st (First) and R
(Reverse) in vehicles equipped with
a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic
transaxle. Do not race the engine,
and spin the wheels as little as pos-
sible. If you are still stuck after a few
tries, have the vehicle pulled out by a
tow vehicle to avoid engine overheat-
ing and possible damage to the
transaxle.
The ESC system should be turned
OFF prior to rocking the vehicle.
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.
CAUTION- Vehicle rocking
Prolonged rocking may causeengine overheating, transaxledamage or failure, and tire dam-age.

Driving your 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.
OBH058035LOMC035004
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.
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.
