POWER OUTLET
To the right of the convenience tray (lower center of
instrument panel) is an outlet for electrically powered
accessories. Pull lightly on the tab of the plastic cover to
access the outlet. The rear power outlet (if equipped) is located in the left
rear cargo area.
The power outlets are a direct feed from the battery so
they receive power whether the ignition is in the ON or
OFF position.
