The instrument panel
brightness control is located
on the driver's side of the
instrument panel.
If it is dark enough outside and your parking lamps are
on, the instrument panel cluster lights and displays and
the backlighting for the door and steering column
switches will come on, and can also be adjusted.
Courtesy Lamps
If it is dark enough outside and the front reading lamp
slider control is in the AUTO position, when any door is
opened all of the vehicles courtesy lamps will come on.
See "Reading Lamps" in the Index. They make it easier
for you to enter and leave the vehicle. The courtesy lamps
will remain on for about 25 seconds after all doors have
been closed. They will then theater dim to off.
Move the front reading lamp slider control in the
overhead console to ON to turn on the interior courtesy
lamps. When the control is moved back to either OFF
or AUTO, the courtesy lamps will immediately turn off.
If the control is OFF when the doors are opened, only
the lower instrument panel courtesy lamps will come on.
Also, if the control is OFF when illuminated entry or
delayed exit lighting are active, only the lower
instrument panel courtesy lamps will be on.
If a door is left ajar, your interior lamps will turn off
after 10 minutes to save your battery.
