Maintenance
LIGHT BULBSUse only bulbs of the specified wattage.
✽
✽NOTICEAfter 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.
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 causedamage to the fuse or electric wiring system.
CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,consult an authorized HYUNDAIdealer. In many cases, it is difficult to replace vehicle light bulbsbecause other parts of the vehiclemust be removed before you canget to the bulb. This is especially true if you have to remove the head-light assembly to
get to the bulb(s).
Removing/installing
the headlight
assembly can result in damage to the vehicle.

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.
