Maintenance and care
WARNING
■Replacing light bulbs
●Be sure to stop the hybrid system and 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 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 light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the light unit. This may
damage the back-up lights or cause condensation to build up on the lens.
●Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts.
