2005 Buick Park Avenue Owner ManualM

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.
SeeHead-Up Display (HUD) on page 3-19for
more information.
You may also have an arrow in the outside mirror that
ashes when the turn signal is used. SeeOutside Power
Mirrors on page 2-37for more information.
To signal a lane change, just raise or lower the lever
until the arrow starts to ash. 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
ash 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 ash 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 asher.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 ash
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.
While the high beams are
on, this light located on the
instrument panel cluster
will also be on.
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.
SeeHead-Up Display (HUD) on page 3-19for
more information.

When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It
is important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they are all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift to THIRD (3) and reduce
your speed to around 45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks behind the
trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake, and then shift to PARK (P).
5. Release the regular brakes.
