Buick 2010 Enclave - Manual (Page 173)

Lighting 6-3
Flash-to-Pass
This feature is used to signal to the
vehicle ahead that you want
to pass.
If the headlamps are off or in the
low‐beam position, pull the turn
signal lever toward you to
momentarily switch to high‐beams.
Release the lever to turn the
high-beam headlamps off.
Daytime Running Lamps
(DRL)/Automatic
Headlamp System
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
A light sensor on top of the
instrument panel makes the DRL
work, so do not cover the sensor.
The DRL system's automatic control
makes the DRL lights come on
when the following conditions
are met:
. The ignition is in the ON/RUN
position.
. The exterior lamps control is
in AUTO.
. The engine is running.
When the DRL are on, only the DRL
lights will be on. The headlamps,
taillamps, sidemarker, and other
lamps will not be on. The instrument
panel and cluster will also not be lit.
When it is dark enough outside, the
DRL lights will turn off and the
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.
The regular headlamp system
should be turned on when it is
needed.
Delayed Headlamps
Delayed headlamps provide a
period of exterior lighting as you
leave the area around the vehicle.
This feature is activated when the
headlamps are on due to the
automatic headlamps control
feature, and when the ignition is
turned off. The headlamps remain
on until the exterior lamps control is
moved to the parking lamps position
or until the pre-selected delayed
headlamp lighting period has ended.
If the ignition is turned off with the
exterior lamp control in the parking
lamps or headlamps position, the
delayed headlamps cycle will
not occur.
To disable the delayed headlamps
feature or change the time of delay,
see Vehicle Personalization on
page 5‑40.
