ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it must
be replaced.

LIGHT BULBS
Use only bulbs of the specified wattage.
✽
✽NOTICE
After 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 engine start/stop button is
in the OFF 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 wattagerating. Otherwise, it may causedamage to the fuse or electricwiring system.CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,consult an authorized HYUNDAIdealer. In many cases, it is difficultto replace vehicle light bulbsbecause other parts of the vehicle must be removed before you canget to the bulb. This is especiallytrue 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.
WARNING
When you replace the front head-
lamp bulb be careful of the HPCU
system, the high voltage cable
(orange color), and high voltage
components for the hybrid system.
It is very dangerous because the
HPCU has high voltage. Do not
touch high voltage systems or it
could result in the electric shock or
burns or even death.
CAUTION
If your vehicle is equipped withHigh Intensity Discharge (HID)headlights, these headlights con- tain mercury. So if you need to haveyour vehicle disposed, you shouldremove the HID Headlights before disposal. The removed HID head-lights should be recycled, re-used or disposed as hazardous waste.
