LIGHT BULBS
G220000AFD-EA
Use only the bulbs of the specified wattage.
All bulbs are available from yourHYUNDAI dealers Parts Department.
✽✽ NOTICE
After washing or driving through heavy rain, condensation may form in the head
and tail lamp lenses. This condition is
caused by the temperature differencebetween 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 vehiclechecked by an authorised HYUNDAI
dealer.
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 move-
ment of the vehicle and burning
your fingers 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 electricwiring system.
CAUTION
If you don’t have necessary tools,
the correct bulbs and the expertise,consult an authorised HYUNDAI dealer. In many cases, it is difficult
to replace vehicle light bulbsbecause 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.

sions. If the bulbs are lit, avoid
contact with liquids. Never touchthe glass with bare hands.
Residual oil may cause the bulb
to overheat and burst when lit. A
