Dome Lamp
The dome lamp will come on when you open any door.
You can also turn the dome lamps on by turning the
instrument panel brightness thumbwheel, located next to
the exterior lamps control, all the way up to the
second notch. In this position, the dome lamps will
remain on whether a door is opened or closed.
You can use the DOME OVERRIDE button, located
below the exterior lamps control, to set the dome lamps
to come on automatically when any door is opened,
or to remain off. To turn the lamps off, press the button
in. With the button in, the dome lamps will remain off
when any door is opened. To return the lamps to
automatic operation, press the button again and return
it to the out position. With the button in this position,
the dome lamps will come on when you open any door.
This will override the illuminated entry feature, unless
you use your remote keyless entry transmitter
(if equipped) to unlock the vehicle.
Battery Rundown Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove box, cargo and underhood lamps if they
are left on for more than 20 minutes when the ignition
is off. This will keep your battery from running down.If the battery rundown protection shuts off the interior
lamps, it may be necessary to do one of the following to
return it to normal operation:
Shut off all lamps and close all doors, or
turn the ignition key to RUN.
Accessory Power Outlets
Your vehicle may be equipped with an accessory
power outlet.
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
There may be an accessory power outlet located near
the center of the vehicle on the lower part of the
instrument panel. A small cap must be pulled down to
access an accessory power outlet. When not using
an outlet be sure to cover it with the protective cap.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed 20 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your battery.
