Driving your vehicle
After you pass through a tollgate
on a highway, Navigation-based
Smart Cruise Control operates
based on the first lane. If you enter
one of the other lanes, the function
might not properly decelerate.
The vehicle will accelerate if the
driver depresses the accelerate
pedal while Navigation-based
Smart Cruise Control is operating,
and function will not decelerate the
vehicle. If not depressing the accel-
erator pedal sufficiently, the vehicle
speed may decrease.
If the driver accelerates and
releases the accelerator pedal
while the Navigation-based Smart
Cruise Control is operating, the
vehicle may not decelerate suffi-
ciently or may rapidly decelerate to
a safe speed.
If the curve is too large or too
small, Navigation-based Smart
Cruise Control may not operate.✽ ✽
NOTICE
• When the function is activated, the
vehicle decelerates automatically
before reaching the curved road
according to its curvature, and the
driving speed returns to the speed
set by Smart Cruise Control after
passing the curved section.
• The speed information on the clus-
ter and navigation may differ
• The time gap could occur between
the navigation's guidance and
when Navigation-based Smart
Cruise Control operation starts
and ends.
• Even if you are driving at a speed
lower than Smart Cruise Control
set speed, acceleration may be lim-
ited by the speeding cameras and
curve sections ahead.
• If Navigation-based Smart Cruise
Control is operating while leaving
the main road to enter an inter-
change, junction, rest area, etc.,
the function may operate for a cer-
tain period of time.
(Continued)(Continued)
Navigation-based Smart
Cruise Control may not oper-
ate due to the existence of
leading vehicles and the driv-
ing conditions of the vehicle.
Always pay attention to road
and driving conditions while
driving.
When you are towing a trailer
or another vehicle, we recom-
mend that Navigation-based
Smart Cruise Control is
turned off due to safety rea-
sons.

Lane Following Assist is designed to
center the vehicle in the chosen lane
by using a front view camera on top
of the windshield.
It can only become active in combi-
nation with Smart Cruise Control
and therefore assists the driver in his
task to control the lateral movement
of the vehicle.
* LFA stands for Lane Following
Assist.
LANE FOLLOWING ASSIST (LFA) (IF EQUIPPED)
ODEP059029
WARNING
It is the driver's responsibility
to operate the steering wheel
for safe driving.
Do not turn the steering wheel
hastily if LFA is operating.
LFA assists the steering
wheel control so that the vehi-
cle can stay in the center of
the lane. LFA does not auto-
matically control the steering
wheel at all times, which
means the driver must keep
hands on the wheel at all
times while driving.
When using LFA, always be
aware of surroundings and
road conditions that may
interrupt or stop LFA.
CAUTION
- Do not attach glass tinting,
stickers, accessories to the
windshield where the front
view camera near the indoor
mirror is placed.
- The removal or re-assembly of
the front view camera to
attach tinting, stickers, acces-
sories may require LFA to be
thoroughly inspected and
modified. In such case, have
your vehicle inspected by an
authorized Kia dealer.
- Inspection or modification
may be required when replac-
ing parts related to the wind-
shield or front view camera,
steering. we recommend that
the system be checked by an
authorized Kia dealer.
