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

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.
