In some cases, it can
temporarily reduce the power
demands of some accessories.
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 battery voltage and
charging message displays.
It is recommended that the
driver reduce the electrical
loads as much as possible. See

Battery Power
Protection
This feature helps prevent the
battery from being drained if
the interior courtesy lamps or
reading lamps are accidentally
left on. If any of these lamps
are left on, they automatically
turn off after 10 minutes when
the vehicle is turned off. The
lamps will not come back on
again until one of the following
occurs:
The vehicle is started.
The doors are closed and
then re-opened.
Exterior Lighting
Battery Saver
The exterior lamps turn off
about 10 minutes after the
vehicle is turned off, if the
parking lamps or headlamps
have been manually left on.
This protects against draining
the battery. To restart the
10-minute timer, turn the
exterior lamp control to the
position and then back to the
or position.
To keep the lamps on for more
than 10 minutes, the vehicle
must be on.
