2000 BUICK REGAL turn signal bulb

2-36 Turn Signal and Lane Change Indicator
The turn signal has the following positions: two upward
(for right) and two downward (for left). 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.
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.
If the arrow flashes faster than normal as you signal a
turn or a lane change, 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 for burned
-out bulbs and then check
the fuse (see ªFuses and Circuit Breakersº in the Index).
A chime will sound if you leave your turn signal on for
more than 3/4 mile (1.2 km).
Headlamp High/Low Beam Changer
To change your headlamps from low beams to high
beams, or high to low, pull the multifunction lever all
the way toward you. Then release it.
When the high beams
are on, this indicator light
located on the instrument
panel cluster will also be on.

4-39 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.
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 and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you are towing a trailer, you may want to drive in
THIRD (3) instead of OVERDRIVE (
) (or, as you
need to, a lower gear).
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's
how to do it:
1. Apply your regular brakes, but don't shift into
PARK (P) yet.
2. Have someone place chocks under the
trailer's 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 shift to PARK (P).
5. Release the regular brakes.
