LFA activation
If the vehicle is inside the lane with
both lanes recognized by the func-
tion, and there is no steep steering
made by the driver, LFA changes into
steering assist mode. The indicator
light will come on green, and the
function helps the vehicle stay in line
by controlling the steering wheel.
When the steering wheel is not con-
trolled temporarily, the indicator light
will flash green and changes to
white.
When the both lanes are not recog-
nized by the function, the function
controls the steering wheel limitedly
whether there is a vehicle in front or
not.
Warning
If you keep your hands off the wheel
while driving with LFA assisting the
steering, the hands-off warning will
be triggered.
If the driver keeps hands off the
wheel even with the hands-off warn-
ing on, the steering assist is tem-
porarily released automatically.
If you put your hands back on the
wheel with LFA released, the steer-
ing assist will re-start.
WARNING
LFA ensures the vehicle stays
in its lane. LFA does not guar-
antee 100% safety. Make sure
you always check road condi-
tions and drive safely at all
times.
Never completely rely on your
LFA.

LFA malfunction
The warning message popped up
(turned off after a certain period of
time)means a problem with LFA. If
this occurs, we recommend that the
system be checked by an authorized
Kia dealer.
CAUTION
Hands-off warnings may be
delayed depending on road
conditions. Always keep your
hands on the steering wheel
while driving.
Hold the steering wheel tight.
Otherwise, LFA could mis-
judge that the driver hands off
the wheel, and a hands-off
warning may occur.
CAUTION
It is the driver’s responsibility
to operate the steering wheel
while driving.
With LFA on, the driver can
steer the vehicle by operating
the wheel on his own.
We recommend that the driver
turns off LFA and operates the
steering wheel by himself in
the following cases
- bad weather
- bad road conditions
- when frequent operation of
the steering wheel is required
- when towing other vehicle or
trailers
The steering wheel can feel
heavy or light if LFA is assist-
ing the steering.

Limitation of the function
If the driver turns on the turn signal
light or the emergency warning
light to change the lane
- Operate the turn signal light
switch before changing the lane
- If you change the lane without
operating the turn signal lights,
steering reaction force of the
wheel may occur.
Once LFA is turned on or the lane
is changed, the vehicle should be
in the center of the road to switch
to the steering assist mode. If the
driver keeps driving along the lane,
LFA will not assist the steering.
When the ESC or VSM is activat-
ed, the function does not assist
steering.
When driving on a curved road at a
high speed, steering assist mode
may not work.
When driving at a speed faster
than 110 mph (180 km/h), steering
assist mode may not work. When sudden steering is made,
the function could be temporarily
deactivated.
If you change the lane in a hurry,
the function does not assist the
steering.
If the vehicle suddenly stops, it
does not assist the steering.
If the lane is too narrow or too
wide, steering is not assisted.
If the function is not able to recog-
nize a vehicle in front and either of
the lanes is not recognized, the
steering is not assisted
If the radius is too small for the
curve
Cautions for the driver
If the lane recognition is difficult or
limited for LFA as shown below, the
driver may need to be careful
because it may not operate or may
cause unnecessary operation.
• Roads or lane markings in bad con-
dition
- When The lane is tainted or invisible
- When the driver cannot see the
lane due to rain, snow, dust,
sand, oil, puddles, etc
- When roads are set or the colors
of the lane and road are not dis-
tinctive
- If there is a sign other than the
lane near the lane or a mark sim-
ilar to the lane
- When the lane is not clear or
damaged
- If the road is covered in the shad-
ows of objects around the road,
such as medians, guard rails,
noise walls, and trees

Steering control
If both lanes are recognized properly
(lane color: white), the steering
wheel indicator ( ) lights up in
green and then the steering control
is initiated.When the function cannot provide
temporary steering inputs, the indi-
cator flashes green and then
changes to white. Even when HDA
cannot provide temporary steering
inputs, it still controls the distance
from other vehicles.
(For information on non-operating
conditions of steering wheel control,
please refer to “Limitations of LFA” in
this chapter.
Warning related to steering
wheel
The hands-off warning appears
when the function detects that the
driver's hands are not on the steering
wheel while HDA is in work.
(First warning: warning message,
Second warning: warning message
with warning sound)

When the hands-off warning
lasts for a certain period of
time
If the driver still does not have their
hands on the steering wheel after the
message "Keep hands on steering
wheel", HDA will be canceled.
However, if Smart Cruise Control is
reactivated manually by the driver,
Highway Driving Assist will reacti-
vate.
To activate Smart Cruise control
refer to "Smart Cruise Control
(SCC)" in this chapter.HDA 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 con-
trolled.
The vehicle is not driven in the mid-
dle of the lane when the function is
turned on or right after changing a
lane.

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

5183
Driving your vehicle
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.
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 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.
