LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.

nal light, front fog light bulb

(1) Headlight (High)
(2) Headlight (Low)
(3) Position light
(4) Front turn signal light
(5) Front fog light (if equipped)
WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the ignition switch is turned to
the LOCK position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION
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
If you don’t have necessary tools,
the correct bulbs and the expertise,
consult an authorized HYUNDAI
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 head-
light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to
the vehicle.

Headlight (HID/LED type) bulb
replacement
If the light bulb is not operating, have the
vehicle checked by an authorized
HYUNDAI dealer.
✽NOTICE
HID/LED lamps have superior per-
formance vs. halogen bulbs. HID/LED
lamps are estimated by the manufactur-
er to last twice as long or longer than
halogen bulbs depending on their fre-
quency of use. They will probably
require replacement at some point in the
life of the vehicle. Cycling the head-
lamps on and off more than typical use
will shorten HID/LED lamps life. HID/
LED lamps do not fail in the same man-
ner as halogen incandescent lamps. If a
headlamp goes out after a period of
operation but will immediately relight
when the headlamp switch is cycled it is
likely the HID/LED lamp needs to be
replaced. HID/LED lighting compo-
nents are more complex than conven-
tional halogen bulbs thus have higher
replacement cost.
Headlight bulb (High)
OHD076046
WARNING- Halogen bulbs
• Halogen bulbs contain pressur-
ized gas that will produce flying
pieces of glass if broken.
• Always handle them carefully,
and avoid scratches and abra-
sions. If the bulbs are lit, avoid
contact with liquids. Never touch
the glass with bare hands.
Residual oil may cause the bulb
to overheat and burst when lit. A
bulb should be operated only
when installed in a headlight.
(Continued)
WARNING -
HID/LED Headlight low
beam (if equipped)
Do not attempt to replace or
inspect the low beam (XENON bulb/
LED) due to electric shock danger.
If the low beam (XENON bulb/LED)
is not working, have your vehicle
checked by an authorized HYUNDAI
dealer.
