2003 Oldsmobile Alero turn signal bulb

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
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.
As you signal a turn or a lane change,
if the arrows
flash rapidly, 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
Fuses and Circuit Breakers on page 5-81.
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.
Headlamps On Reminder
If you open the driver’s door and turn off the ignition
while leaving the lamps on, you will hear a warning
chime.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high
beam, push the turn signaVmultifunction lever away
from you.
When the high beams are
on, a light on the
instrument panel cluster
will come on
if the ignition
is in
ON.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward you.

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 stiil 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.
P; ‘ting on Hills
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) for an automatic transaxle or into a
gear for a manual transaxle, yet. When parking
uphill, turn your wheels away from the curb. When
parking downhill, turn your wheels into the curb.
2. Have someone place chocks under the trailer
1/:!?ee!s.
3. When the 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 into PARK (P) for an
automatic transaxle or
REVERSE (R) for a manual
transaxle.
5. Release the regular brakes.
