Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. 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 for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.Information
After heavy driving, rain or washing,
headlamp and trunk lenses could
appear frosty. This condition is caused
by the temperature difference
between the lamp inside and the out-
side temperature. This is similar to the
condensation on your windows inside
your vehicle during the rain and does-
n’t indicate a problem with your vehi-
cle. If the water leaks into the lamp
bulb circuitry, have your vehicle
checked by an authorized HYUNDAI
dealer.
i
Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the igntion switch to the
LOCK/OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be hot
and may burn your fingers.

Handle halogen bulbs with
care. Halogen bulbs contain
pressurized gas that will pro-
duce flying pieces of glass
that could cause injuries if
broken.
Wear eye protection when
changing a bulb. Allow the
bulb to cool down before han-
dling it.

Maintenance
Always handle them carefully, andavoid scratches and abrasions. 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.

If a bulb becomes damaged or cracked, replace it immediately
and carefully dispose of it.
1. Open the hood.

3. Remove the headlamp bulb cover by turning it counterclockwise.
4. Disconnect the headlamp bulb socket-connector. 5. Unsnap the headlamp bulb retain-
ing wire by pressing the end and
pushing it upward.
6. Remove the bulb from the head- lamp assembly.
7. Install a new headlamp bulb and snap the headlamp bulb retaining
wire into position by aligning the
wire with the groove on the bulb.
