A high electrical load occurs when several of the
following are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer loads,
and loads plugged into accessory power outlets.
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 4‑43

Battery Run-Down Protection
The vehicle has a battery run-down protection feature
designed to protect the vehicle's battery.
When any interior lamp (trunk, reading, or visor vanity)
is left on while the ignition is turned off, the battery
run-down protection system will automatically shut the
lamp(s) off after 20 minutes. This will avoid draining the
battery.
To reactivate the interior lamps, do one of the following:
.
Turn on the ignition.
.
Turn the exterior lamp control off and then on.
.
Open a door.
.
Press any Remote Keyless Entry (RKE) transmitter
button (if equipped).
.
Press the remote trunk release button.
.
Press the power door lock switch.
The battery run-down feature will also be activated
when any door on the vehicle is left open and the
ignition is in LOCK/OFF.
