turn signal bulb CHEVROLET ASTRO 2003 Owners Manual

Turn SignaVMultifunction Lever
The lever on the driver’s side of the steering column
includes the following:
Turn and Lane Change Signals
Headlamp High/Low-Beam Changer
Flash-to-Pass
Windshield Wipers
Windshield Washer
Cruise Control (Option)
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
Dane1 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.
As you signal a turn or a lane change, if the arrows
flash faster, a signal bulb may be burned out and other
drivers won’t see your turn signal.
For information on the exterior lamps, see
Exterior
Lamps
on page 3-12.
3-6

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 a blown fuse.
See
Fuses and Circuit Breakers on page 5-93.
If you have a trailer towing option with added wiring
for the trailer lamps, a different turn signal flasher
is used. With this flasher installed, 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.
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 center position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high 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 also will
be on.
Flash-to-Pass
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 in automatic.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are in automatic 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 located on the cluster comes on.
Release the lever to return to normal operation.
3-7

Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left.
To move the trailer to the right, move your
hand to the right. Always back up slowly and,
if possible,
have someone guide you.
Making Turns
Notice: Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring (included in the optional trailering package).
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.
