turn signal bulb BUICK PARK AVENUE 2001 Owner's Manual

2-37
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 won't see your
turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs.
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.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high to
low, pull the turn signal lever toward you, then release it.
When the high beams are
on, a light on the instrument
panel cluster will also be on.
If your vehicle is equipped
with HUD, this light
will also appear in the
display area.
Flash-to-Pass Feature
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are off.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are off or on low beam, your
high
-beam headlamps will turn on. They'll stay on as
long as you hold the lever toward you and the
high
-beam indicator on the instrument panel cluster
comes on. Release the lever to turn the high
-beam
headlamps off.

4-38 Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a different
turn signal flasher and/or extra wiring. Check with your
dealer. The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you're about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash 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's 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're 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 gear before you start
down a long or steep downgrade. If you don't 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 down to THIRD (3) and
reduce your speed to around 45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
