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 or Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible.
Battery Run-Down Protection
Your vehicle has a feature to help prevent you
from draining the battery, in case you accidentally
leave the interior lamps on. If you leave any
interior lamps on while the ignition is in lock or off,
they will automatically turn off after 10 minutes.
The lamps will not come back on again until
you do one of the following:
• Turn the ignition to RUN or ACCESSORY
• Open a closed door, or close and reopen
a door.
• Turn the interior lamps on if they are in the
door or override position.
• Turn the interior lamps to the door or override
position and then to on again if the interior
lamp control is in the on position.
If your vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off
the lamps after only three minutes.
