Battery Load
Management
The vehicle has Electric Power
Management (EPM) that
estimates the battery
temperature and state of
charge. It then adjusts the
voltage for best performance
and extended life of the 12–
volt battery
When the battery state of
charge is low, the voltage is
raised slightly to quickly
increase the charge. When thestate of charge is high, the
voltage is lowered slightly to
prevent over charging. As this
adjustment occurs, you may
see the voltage move up or
down on the voltmeter gauge
or voltage display on the
Driver Information (DIC),
if equipped. This is normal. If a
problem occurs, an alert will be
displayed.
If the electrical loads are very
high, the battery can be
discharged when the vehicle is
stationary. A high electrical
load occurs when several
features are on, such as:
headlamps, high beams, rear
window defogger, climate
control fan at high speed,
heated seats, motor cooling
fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent
excessive discharge of the
battery by balancing the
electrical system output and
the vehicle's electrical needs.
