LFA system malfunction
The warning message popped up
(turned off after a certain period of
time)means a problem with LFA sys-
tem. If this occurs, we recommend
that the system be checked by an
authorized Kia dealer.
CAUTION
Hands-off warnings may be
delayed depending on roadconditions. Always keep yourhands on the steering wheelwhile driving.
Hold the steering wheel tight. Otherwise, LFA system couldmisjudge that the driverhands off the wheel, and ahands-off warning may occur.
CAUTION
It is the driver’s responsibility to operate the steering wheelwhile driving.
With LFA system on, the driv- er can steer the vehicle byoperating the wheel on hisown.
We recommend that the driver turns off LFA system andoperates the steering wheelby himself in the followingcases
- 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 system isassisting the steering.

Limitation of the system
If the driver turns on the turn signallight or the emergency warning
light to change the lane
- Operate the turn signal lightswitch 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 system 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 system will not
assist the steering.
When the ESC or VSM is activat- ed, the system 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 system could be temporarily
deactivated.
If you change the lane in a hurry, the system 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 system 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 the LFA system 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 system cannot provide
temporary steering inputs, the indi-
cator flashes green and then
changes to white. Even when HDA
system 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
system” in this chapter.
Warning related to steering

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 system will be can-
celed. However, if Smart Cruise
Control is reactivated manually by
the driver, Highway Driving Assist
system will reactivate.
To activate Smart Cruise control
refer to "Smart Cruise Control
(SCC)" in this chapter. HDA system 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 system is
turned on or right after changing a
lane.
ESC (Electronic Stability Control or VSM (Vehicle Stability
Management) is activated.
The vehicle is driven on a sharp curve.
Vehicle speed is over 95 mph (153 km/h)
The vehicle makes sharp lane changes.
CAUTION
The hands-off warning may be delayed depending on roadconditions. Always keep yourhands on the steering wheelwhile driving.
If you hold the steering wheel lightly, it may be perceivedthat the steering wheel is notheld at all and trigger thehands-off warning.

Highway Driving Assist systemmay not function properly in thefollowing situations:
The navigation is not working properly.
The navigation is not updated. The real-time GPS or map information provided haserrors.
The navigation is overloaded by performing functions suchas route search, video play-back, voice recognition, etc.are performing simultaneously.
The navigation is recalculat- ing the route while driving.
GPS signals are blocked in areas such as a tunnel.
The driver goes off course or the route to the destination ischanged or canceled by reset-ting the navigation.
The vehicle enters a service station or rest area
(Continued)
(Continued) The speed limit of selected highway section is changeddue to road conditions.
Android Auto or Car Play is operating.
The navigation cannot detect the current vehicle position(ex: elevated roads includingoverpass adjacent to generalroads or nearby roads exist ina parallel way).
The navigation is being updat- ed while driving.
The navigation is being reset while driving.
The road is slippery due to bad weather such as rain orsnow.
If your vehicle tows a trailer or another vehicle, you shouldrelease Highway DrivingAssist system. Operating thebrake system or steering sys-tem while towing mayadversely affect the safety.

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.
