You can plug accessory electrical equipment into an
accessory power outlet. Just pull on the outlet cover 
to remove it and follow the proper installation
instructions that are included with any electrical
equipment that you install.

The accessory power outlet is located on the passenger’s
side of the front storage compartment.

These circuits are protected by a fuse and have
maximum current levels.

Certain power accessory plugs may not be compatible to
the power accessory outlet and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer for additional information on the power
accessory plugs.
