EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 4 ‑ 62 . Battery Run-Down Protection This feature helps prevent the battery from being drained, if the interior courtesy lamps, reading/map lamps, visor vanity lamps or trunk lamp are accidentally left on. If any of these lamps are left on, they automatically turn off after 10 minutes, if the ignition is off. The lamps will not come back on again until one of the following occurs: . . The ignition is turned on. The exterior lamps control is turned off, then on again. The headlamps will timeout after 10 minutes, if they are manually turned on with the ignition on or off. Accessory Power Outlet(s) The accessory power outlets can be used to plug in electrical equipment, such as a cell phone or MP3 player. If the vehicle has a center console, the power outlet is located inside the lower storage area. Some vehicles may have an outlet on the right front lower part of the driver's seat and under the climate control system next to the ashtray. See Center Console Storage on page 3 ‑ 52 . Inadvertent Power Battery Saver This feature protects the vehicle battery against drainage from the interior lamps, trunk lamp, glove box lamp, or the garage door opener. When the ignition is turned off, the power to these features automatically turns off after 10 minutes. Power is restored for an additional 10 minutes if any door or trunk is opened, or the courtesy lamp switch is turned on. 4-31
