Headlamp High/Low-Beam Changer - Buick 2005 Park Avenue Owner's Manual

If your vehicle is equipped with the Head-Up Display
(HUD), an arrow will also appear in the display area to
indicate the direction of the turn or lane change.
See Head-Up Display (HUD) on page 3-19 for
more information.
You may also have an arrow in the outside mirror that
flashes when the turn signal is used. See Outside Power
Mirrors on page 2-37 for more information.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
flash at twice the normal rate, this may indicate that a
signal bulb may be burned out and other drivers will not
see your turn signal. If a bulb is burned out, replace
it to help avoid an accident.
If the arrows do not go on at all when you signal a turn,
check the fuse and check for burned-out bulbs. See
Fuses and Circuit Breakers on page 5-92.
If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will flash even
if a turn signal bulb is burned out. Check the front and
rear turn signal lamps regularly to make sure they
are working. You do not need to add a different flasher.

Turn Signal On Chime
If your turn signal is left on for more than three-quarters
of a mile (1.2 km), a chime will sound at each flash
of the turn signal. To turn off the chime, move the turn
signal lever to the off position.

Headlamp High/Low-Beam Changer

To change the headlamps from low beam to high
beam or high beam to low beam, pull the turn signal
lever toward you and release it.
If your vehicle is equipped with the Head-Up
Display (HUD), this symbol will also appear in the
display area to indicate the high beams are on.
See Head-Up Display (HUD) on page 3-19 for
more information.
While the high beams are
on, this light located on the
instrument panel cluster
will also be on.
