6-3. Do-it-yourself maintenance
CAUTION
■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after turning
off the lights.
The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the li ght bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth to avoid
getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failure to do so may
result in heat damage, fire, or water en tering the headlight unit. This may damage
the headlights or cause condensati on to build up on the lens.
●While the headlights are turned on, and for
a short time after they have been turned off,
metal components at the rear of the head-
light assembly will be extremely hot. To pre-
vent burns, do not touch these metal
components until you are certain they have
cooled down.
