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 9.
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.

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.

Maintenance

If you don’t have the necessary tools,
the correct bulbs and the expertise,
consult an authorized Kia dealer. In
many cases, it is difficult to replace
vehicle light bulbs because other
parts of the vehicle must be removed
before you can get to the bulb. This is
especially true if you have to remove
the headlamp assembly to get to the
bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
If non-genuine parts or substandard
bulbs are used, it may lead to blow-
ing a fuse or other wiring damages.
Do not install extra lamps or LEDs to
the vehicle. If additional lights are
installed, it may lead to lamp mal-
functions and flickering. Additionally,
the fuse box and other writing may
be damaged.

WARNING

- HID

(XENON bulb) due to electric
shock danger. If the light bulb
does not operate, have your

Maintenance

✽

NOTICE

HID lamps have superior perform-
ance vs. halogen bulbs. HID lamps
are estimated by the manufacturer to
last twice as long or longer than halo-
gen bulbs depending on their fre-
quency of use. They will probably
require replacement at some point in
the life of the vehicle. Cycling the
headlamps on and off more than typ-
ical use will shorten HID lamps life.
HID lamps do not fail in the same
manner as halogen incandescent
lamps. If a headlamp goes out after a
period of operation but will immedi-
ately relight when the headlamp
switch is cycled it is likely the HID
lamp needs to be replaced. HID
lamping components are more com-
plex than conventional halogen bulbs
thus have higher replacement cost.
