Buick 2004 Park Avenue - Manual (Page 124)

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is finished, the lever will return
automatically.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
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 3-18 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 2-39 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 5-99.
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 3/4 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.
