Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
The vehicle has two accessory power
outlets:
.Inside the center console
storage area.
.On the rear of the center floor
console.
Lift the cover to access the accessory
power outlet.
Certain electrical accessories may not
be compatible with the accessory
power outlet and could overload a
vehicle circuit breaker or adapter fuse.
If overloaded, the circuit breaker will
reset after all devices are disconnected
or if Retained Accessory Power (RAP)
is turned off and then back on. See
Retained Accessory Power (RAP) 0237.
Wait one minute to allow the circuit
breaker to reset before reconnecting
devices or turning RAP back on. If the
problem continues, the issue could be
within your device. Try another
known good device to make sure the circuit breaker is operating properly.
If this does not resolve your problem,
see your dealer.
Caution
Failure to replace the circuit
breaker with the minifuse could
overheat the cigar lighter and
damage the vehicle.
When adding electrical equipment, be
sure to follow the proper installation
instructions included with the
equipment. See Add-On Electrical
Equipment 0321.
Caution
Hanging heavy equipment from the
power outlet can cause damage not
covered by the vehicle warranty.

When the vehicle is started, the
passenger airbag status indicator will
light ON and OFF, and the symbols for
on and off, for several seconds as a
system check. Then, after several more
seconds, the status indicator will light
either ON or OFF, and either the
symbol for on or off, to let you know
the status of the front outboard
