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.
Information - Desiccant
(if equipped)
This vehicle is equipped with desic-
cant to reduce fogging inside the head-
lamp due to moisture.
The desiccant is consumable and its
performance may change based on the
used period or environment.
If fogging inside the headlamp due to
moisture continues for a long time,
have your vehicle checked by an
authorized HYUNDAI dealer. Headlamp, Parking Lamp, Turn

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 fin-
gers.

that could cause injuries if
broken.
