Lighting 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 or BATTERY VOLTS LOW. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See Driver Information Center (DIC) on page 5￿28. 6-9 Battery Power Protection This feature helps to prevent battery drain if accessory lamps are left on. If accessory lamps such as the vanity mirror, cargo, reading, console, or glove box are left on, they automatically time out after about 20 minutes. To reset the battery protection, all of the above lamps must be turned off or the ignition must be in the ACC/ACCESSORY position. Exterior Lighting Battery Saver The exterior lamps turn off about 10 minutes after the ignition is turned to LOCK/OFF, if the parking lamps or headlamps have been manually left on. This protects against draining the battery. To restart the10 minute timer, turn the exterior lamp control to OFF and then back to the parking lamp or headlamp position. To keep the lamps on for more than 10 minutes, the ignition must be in the ACC/ACCESSORY or ON/RUN position.
