2002 BUICK REGAL turn signal bulb

2-41
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.
Flash-to-Pass Feature
This feature lets you use your high-beam headlamps
to signal the 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 a little,
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 dash will come on.
Release the lever to return to normal operation.

4-41 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 AUTOMATIC 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.
