Maximum rated capacity for the auxiliary
DC jack:
DC 12V, 120W (10 A)
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 accessory with a plug that
gets hot. A hot plug can damage the
auxiliary jack.
