Buick 2009 Enclave - Manual (Page 137)

When it is dark enough outside, the DRL will turn off
and the vehicle’s headlamps and parking lamps will turn
on. The other lamps that come on with the headlamps
will also come on.
When it is bright enough outside, the headlamps will go
off and the DRL will come on.
To idle the vehicle with the DRL off, turn the exterior
lamp control off and then do one of the following:
• Turn the exterior lamp control to the parking lamp
position.
• Turn the exterior lamp control to the headlamp
position.
• Turn the exterior lamp control from AUTO to off and
back to AUTO.
This feature is not available for vehicles first sold in
Canada.
To turn off the automatic headlamp feature when it
is dark outside, move the exterior lamp control to the
parking lamp position. The parking lamps remain on
and the headlamps turn off. The fog lamps also go on
if they were on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
For vehicles with fog lamps, the button is located in the
center of the exterior lamps control on the left side of
the steering column.
#
: Press to turn the lamps on or off.
While the high-beam headlamps are on, the fog lamps
are off.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on
after the ignition has been turned to off, the exterior
lamps will turn off after about 10 minutes. This protects
the battery from being drained.
Use the exterior lamp control to turn the lamps back on,
if they are still needed.
