This feature controls the brightness of the instrument
panel lights.

The lever for this feature 
is located on the 
overhead console.

Slide the lever toward the symbol to brighten the lights
or away from it to dim them.

If you slide the lever all the way toward the symbol past
the resistance point, the interior lamps will come on. To
turn them off, slide the lever back toward the minimum
brightness setting.

The illuminated entry system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the remote
keyless entry transmitter unlock button. If activated by
the transmitter, the lighting will remain active for about
25 seconds. The illuminated entry system uses the light
sensor, it must be dark outside in order for the lamps to
turn on. The lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.

This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on. 
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument panel
displays can be adjusted by sliding the instrument panel
brightness lever toward the symbol to brighten or away
from the symbol to dim the lighting.
