LIGHT BULBS
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.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.
Information
After heavy driving rain or washing,
the lamps could appear frosty. This
condition is caused by the temperature
difference between the lamp inside and
the outside temperature. This is similar
to the condensation on your windows
inside your vehicle when raining and
doesn’t indicate a problem with your
vehicle. If the water leaks into the light
bulb circuitry, have your vehicle
checked by an authorized HYUNDAI
dealer.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorized
HYUNDAI dealer.
• The position lamp may not turn on
when the position lamp switch is
turned on, but the position lamp and
headlamp switch may turn on when
the headlamp switch is turned on.
This may be caused by network fail-
ure or vehicle electrical control sys-
tem malfunction. If this occurs, we
recommend the system be checked
by an authorized HYUNDAI dealer.

NOTICE
Prior to working on a light, firmly
apply the parking brake, ensure
that the ignition switch is in the
LOCK/OFF position and turn off
the lights to avoid sudden move-
ment of the vehicle and burning
your fingers or receiving an elec-
tric shock.
