AUXILIARY POWER POINT (12V DC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
Auxiliary power points can be found in the following locations:
• On the instrument panel
• Inside the center console storage area (if equipped)
• On the rear of the center console (if equipped) accessible from the
rear seat
Always keep the power point caps closed when not being used.
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12V DC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer to Fuses and
relays in the Roadside Emergencies chapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
• do not use the power point longer than necessary when the engine is
not running,
