LIGHT BULBS
Bulb replacement precaution
Please keep extra bulbs on hand
with appropriate wattage ratings in
case of emergencies.
Refer to “Bulb Wattage” in chapter 8.
When changing lamps, first turn off
the engine at a safe place, firmly
apply the parking brake and detach
the battery’s negative (-) terminal.
Use only bulbs of the specified
wattage.✽ ✽
NOTICE
• If the light bulb or lamp connector
is removed while the lamp is still
on, the fuse box's electronic sys-
tem may log it as a malfunction.
Therefore, a lamp malfunction
incident may be recorded as a
Diagnostic Trouble Code (DTC) in
the fuse box.
• It is normal for an operating lamp
to flicker momentarily. This is due
to a stabilization function of the
vehicle’s electronic control device.
If the lamp lights up normally
after momentarily blinking, then
it is functioning as normal.
However, if the lamp continues to
flicker several times or turns off
completely, there may be an error
in the vehicle’s electronic control
device. Please have the vehicle
checked by an authorized Kia
dealer immediately.
✽ ✽
NOTICE
We recommend that the headlight
aiming be adjusted by an authorized
Kia dealer after an accident or after
the headlight assembly is reinstalled.
WARNING- Working on
the lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the engine
start/stop button is in OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle and burning your fingers
or receiving an electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned-
out bulb with one of the same
wattage rating. Otherwise, it
may cause damage to the fuse
or electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do not
clean the headlamp lens with
chemical solvents or strong
detergents.
