CAUTION:_
Do not use accessories requiring more
than the above maximum capacity. This
may overload the circuit and cause the
fuse to blow.
If accessories are used without the engine
running or with the headlights turned on,
the battery will lose its charge and engine
starting may become difficult.
Do not use an automotive cigarette lighter
or other accessories with a plug that gets
hot because the jack can be damaged.
