Features of your vehicle
Headlight leveling device
(if equipped)
Automatic type
To ensure the proper headlight beam
is used under various conditions, the
headlight beam levels are automati-
cally adjusted depending on the
number of passengers, the weight in
the trunk, and other driving condi-
tions.
✽ ✽NOTICE
If the headlight beam is irradiated
to the high or low position, have the
system be inspected by an author-
ized Kia dealer.
Do not attempt to inspect or replace
the wiring yourself.
Dynamic Bending Light (DBL)
(if equipped)
Dynamic Bending Light (DBL) uses
the steering angle and vehicle speed,
to keep your field of vision wide by
swiveling and leveling the headlamp.
Change the switch to the AUTO posi-
tion when the engine is running. The
dynamic Bending Light (DBL) will
operate when the headlamp is ON.
To turn off the DBL, change the
switch to other positions. After turn-
ing the DBL off, headlamp swiveling
no longer occurs, but leveling oper-
ates continuously. If the DBL malfunction indicator
comes on, the DBL is not working
properly. Drive to the nearest safe
location and restart the engine. If the
indicator continuously remains on,
have system be checked by an
authorized Kia dealer.

Limitation of the system
The Forward Collision-Avoidance
Assist (FCA) system is designed to
monitor the vehicle or pedestrians
ahead in the roadway through cam-
era recognition to warn the driver
that a collision is imminent, and if
necessary, apply emergency brak-
ing.
In certain situations, the camera may
not be able to detect the vehicle or
pedestrians ahead. In these cases,
the FCA system may not operate
normally. The driver must pay careful
attention in the following situations
where the FCA operation may be
limited.
Detecting vehicles
The sensor may be limited when:
The camera is covered object ordebris
Inclement weather such as heavy rain or snow obscures the field of
view of the camera
The camera recognition is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system. (for example a trac-
tor, trailer, etc.)
The camera's field of view is not well illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have their rear lights properly turned ON
or their rear lights are located
unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road.
The field of view in front is obstructed by sun glare or head-
light of oncoming vehicle.
The windshield glass is fogged up.
The vehicle in front is driving errat- ically.
The vehicle is on unpaved or uneven rough surfaces, or roads
with sudden gradient changes.
The vehicle is drives inside a build- ing, such as a basement parking lot
The camera does not recognize the entire vehicle in front.
The camera is damaged.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
Adverse road conditions cause excessive vehicle vibrations while
driving
The sensor recognition changes suddenly when passing over a
speed bump

The sensor may be limited when:
The radar sensor or camera is cov-
ered with a foreign object or debris
The camera lens is contaminated due to tinted, filmed or coated
windshield, damaged glass, or
stuck of foreign matter (sticker,
bug, etc.) on the glass
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves
Something in the path of travel deflects the radar waves.
The radar/camera recognition is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system. (for example a trac-
tor, trailer, etc.) The camera's field of view is not well
illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have their rear lights properly turned ON
or their rear lights are located
unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
When light coming from a street light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road
The field of view in front is obstructed by sun glare or head-
light of oncoming vehicle.
The windshield glass is fogged up

The vehicle is on unpaved or uneven rough surfaces, or roads
with sudden gradient changes The vehicle is driven near areas
containing metal substances as a
construction zone, railroad, etc.
The vehicle is drives inside a build- ing, such as a basement parking lot

Maintenance
✽ ✽NOTICE
If you connect unauthorized elec-
tronic devices to the battery, the bat-
tery may be discharged. Never use
unauthorized devices.
Recharging the battery
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in a short time (because, for exam-
ple, the headlamps or interior
lamps were left on while the vehi-
cle was not in use), recharge it by
slow charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.WARNING- Risk of elec-
trocution
Never touch the electrical igni-
tion system while the vehicle is
running. This system works
with high voltage which can
shock you.
WARNING- Recharging Battery
Never attempt to recharge the
battery when the battery cables
are connected.
WARNING- Battery lead
compound
Battery posts, terminals, and
related accessories contain
lead and lead compounds.
Wash hands after handling.
