✽
✽
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
turned to the LOCK position and
turn off the lights to avoid sudden
movement of the vehicle and burn-
ing your fingers 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 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 difficultto replace vehicle light bulbsbecause other parts of the vehicle must be removed before you canget to the bulb.
