2004 CHEVROLET IMPALA turn signal bulb

Turn and Lane-Change Indicator
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 nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ash 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 ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If the arrow ashes 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. SeeFuses and Circuit Breakers on page 5-103.
Turn Signal On Chime
If you leave either one of your turn signals on and drive
more than 3/4 mile (1.2 km), a chime will sound to
alert you.
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.
While the high beams are
on, this light on the
instrument panel cluster
also will be on.
This light works only while the ignition key is in the
ON position, and your fog lamps (if equipped) will not
be illuminated when your high beams are on.

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 may need additional
wiring. Check with your dealer. The arrows on your
instrument panel will ash whenever you signal a turn or
lane change. Properly hooked up, the trailer lamps
will also ash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash 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 gearbeforeyou 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 have overdrive, you may want to drive in
THIRD (3) instead of AUTOMATIC OVERDRIVE
X.
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.
