Pontiac 2005 Bonneville - Manual (Page 129)

If the Twilight Sentinel ® lighting is active, it can be
disabled by turning on the manual parking lamps. This
lighting will be disabled until the key is turned from
ON or until the manual parking lamps are turned off.
Also, it is possible that your headlamps may go
out if you drive from a dark area into a bright area like a
lighted parking lot. If this happens, turn on your
headlamps with the exterior lamp control.
Exterior Lighting Battery Saver
If the exterior lamp control has been left on, the exterior
lamps will turn off about 10 minutes after the ignition
is turned to OFF and a door has been opened.
This protects against draining the battery in case you
have accidentally left the headlamps or parking
lamps on. If you need to leave the lamps on for more
than 10 minutes, use the exterior lamp control to turn the
lamps back on after turning the ignition to OFF and
opening a door. To delay the lamps from turning off, see
“Twilight Sentinel
® ,” listed previously.
Instrument Panel Brightness
When it is dark outside, you can brighten or dim your
instrument panel cluster lights using the DIM knob,
located to the left of the steering wheel on the
instrument panel.
Turn the knob clockwise to brighten the instrument
panel cluster lights and displays. Turn the knob
clockwise all the way to turn on the interior courtesy
lamps. Turn the knob counterclockwise to dim the
instrument panel cluster lights and displays and to turn
off the courtesy lamps.
Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps will come on. They make it easier for you
to enter and leave the vehicle. Turn the DIM knob all
the way clockwise to turn the interior courtesy lamps on.
