We recommend that you 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
headlight assembly to get to the bulb(s).
Removing/installing the headlight
assembly can result in damage to the
vehicle.
WARNING
Prior to replacing a light, depress the
foot brake, move the shift lever into the
N (Neutral, for Automatic transmission
vehicle) or neutral (for manual
transmission vehicle), apply the parking
brake, place the ignition switch in 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.
NOTICE
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.
i Information
The headlight and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night
in wet weather. This condition is caused
by temperature difference between the
lamp inside and outside and, it does not
indicate a problem with your vehicle.
When moisture condenses in the lamp,
it will be removed after driving with the
headlight on. The removable level may
differ depending on lamp size, lamp
position and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
by an authorized HYUNDAI dealer.
