Interior Lights
The interior lights come on when a door is opened.
To protect the battery, the interior lights will turn off
automatically 10 minutes after the ignition is moved to
the LOCK position. This will occur if the interior lights
were switched on manually or are on because a door is
open. This includes the glove box light and the trunk
light. To restore interior light operation, either place the
ignition in the ON/RUN position or cycle the light
switch.
Dimmer Controls
The dimmer control is part of the headlight switch and is
located on the left side of the instrument panel.
