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. If a
battery message is displayed, it is
recommended that the driver reduce
the electrical loads as much as
possible. See Driver Information Center
(DIC) (Base Level) 0 112 or
Driver Information Center (DIC)
(Uplevel) 0 115.

Battery Power Protection

The battery saver feature is designed
to protect the vehicle's battery.
If some interior lamps are left on and
the ignition is turned off, the battery
rundown protection system
automatically turns the lamp off after
some time.

Exterior Lighting Battery

Saver

The exterior lamps turn off about
10 minutes after the ignition 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
position.
To keep the lamps on for more than
10 minutes, the ignition must be on or
in ACC/ACCESSORY.
