A high electrical load occurs when several of the
following loads are on: 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 or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 232.Battery Run-Down Protection
Your vehicle has a feature to help prevent the
battery from being drained, in case the underhood
lamp, vanity mirror lamps, cargo lamps, reading
lamps, console, or glove box lamps are
accidentally left on, or something is left plugged
into the accessory power outlet or cigarette lighter.
If any of the accessory lamps are left on, they
will 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. position.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.

Battery Saver Active
This message appears when the system detects
that the battery voltage is dropping beyond a
reasonable level. The battery saver system will
start reducing certain features of the vehicle which
you may be able to notice. At the point that the
features are disabled, this message is displayed. It
means that the vehicle is trying to save the
charge in the battery.
Turn off all unnecessary accessories to allow the
battery to recharge.
The normal battery voltage range is
11.5 to 15.5 volts. You can monitor battery voltage
on the DIC by pressing the INFO button until
BATTERY VOLTS appears.
Battery Voltage High
This message indicates that the electrical charging
system is overcharging the battery. When the
system detects that the battery voltage is above
an estimated 16 volts, this message will be
displayed.To reduce the charging overload, use the vehicle’s
accessories. Turn on the exterior lamps and
radio, set the climate control on AUTO and the fan
speed on the highest setting, and turn the rear
window defogger on.
The normal battery voltage range is
11.5 to 15.5 volts when the engine is running. You
can monitor battery voltage on the DIC by pressing
the INFO button until BATTERY VOLTS appears.
Battery Voltage Low
This message will appear when the electrical
system is charging less than 10 volts or if
the battery has been drained.
If this message appears immediately after starting
the engine, it is possible that the generator can
still recharge the battery. The battery should
recharge while driving but may take a few hours to
do so. Consider using an auxiliary charger to
boost the battery after returning home or to a nal
destination. Make sure you follow the
manufacturer’s instructions.
