Entry/Exit Lighting
When you open any door, the lamps inside of your
vehicle will go on. These lamps will fade out 10 seconds
after the last door is closed, or when the ignition is
turned on after all doors have been closed. These lamps
will also go on when you press the trunk release
button, the unlock button or the horn symbol button on
the remote keyless entry transmitter.
The lamps inside of your vehicle will stay on for about
10 seconds after your key is removed from the ignition to
provide an illuminated exit.
Dome Lamp
The switch on this lamp has three positions. The ON
position will turn on the lamp. The DOOR position
will turn on the lamp whenever a door is opened.
The OFF position will shut off the lamp completely,
even when a door is opened.
Trunk Lamp
The trunk lamp comes on when you open your trunk.
Battery Run-Down Protection
Your vehicle has a battery run-down protection feature
designed to protect your vehicle's battery.
When any interior lamp (trunk, reading, footwell, visor
vanity or glove box) is left on when 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 transmitter button
(if equipped),
press the remote trunk release button, or
*
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 OFF.
