Auxiliary Power Jacks
These jacks provide 12-volt power so you can operate
things such as a citizen's band (CB) radio or a
cellular phone. You'll see positive (red) and negative
(black) outlets. They are protected by a 15-amp circuit
breaker.
Notice: Whether or not your vehicle has the power
outlets, don't plug in FM communications gear at
the ashtray area. FM equipment creates high
heat, and over time the area could get so hot that
wires could be damaged or a fire could break out.
If your vehicle has these
power jacks, you'll find
then in the console to
the right of the
driver's seat.
