WARNING
■Replacing light bulbs
●Only replace a bulb when it is cool enough to touch. Do not attempt to
replace bulbs while they are hot, as doing so 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 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 the light bulbs and any parts used to secure them. Failure to
do so may result in heat damage, fire, or water entering a light unit. This
may damage the light or cause condensation to build up on the inner side
of the lens.
■When changing the back-up lights
Stop the engine and wait until the exhaust pipes have cooled down suffi-
ciently. The lights are located near the exhaust pipe and touching a hot
exhaust pipe can cause burns.
■To prevent damage or fire
Make sure bulbs are fully seated and locked.
