Conserving electrical current

Keep the following in mind to help minimize battery drain:
• When the engine is not running, avoid using ignition mode II. Many electrical systems (the audio system, the optional navigation system, power windows, etc) will function in ignition modes 0 and I. These modes reduce drain on the battery.
• Please keep in mind that using systems, accessories, etc., that consume a great deal of current when the engine is not running could result in the battery being completely drained. Driving or having the engine running for approximately 15 minutes will help keep the battery charged.
• The optional 12 volt socket in the cargo area provides electrical current even with the ignition switched off, which drains the battery.
