Lighting 6-7
This is because the generator
(alternator) may not be spinning
fast enough at idle to produce all of
the power needed for very high
electrical loads.
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 DIC message might
be displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑24.
Battery Power 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.
