■Replacing light bulbs
● Turn off the lights. Do not attempt to replace the bulb immedia tely after
turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clea n dry cloth
to avoid getting moisture and oils on the bulb. Also, if the bu lb is scratched
or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Fa ilure to do so
may result in heat damage, fire, or water entering the headligh t unit. This
may damage the headlights or cause condensation to build up on the lens.
● Do not attempt to repair or disassemble the bulb, socket, elect rical wiring,
or sub components. This may cause serious injury due to electri c shock.
●Vehicles with discharge headlights:
While the low beam headlights are
turned on, and for a short time after they
have been turned off, metal compo-
nents at the rear of the headlight
assembly will be extremely hot. To pre-
vent burns, do not touch these metal
components until you are certain they
have cooled down.
