2003 CADILLAC ESCALADE EXT 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 ®nished, the lever will return
automatically.
To signal a lane change, 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.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
As you signal a turn or a lane change, if the arrows
¯ash more quickly than normal, 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 a blown fuse.
See
Fuses and Circuit Breakers on page 5-101.
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 ¯ash of the
turn signal and the message TURN SIGNAL ON will
also appear in the DIC. To turn the chime and message
off, move the turn signal lever to the off position.
Headlamp High/Low-Beam Changer
53
(Headlamp High/Low Beam Changer):
To change the headlamps from low to high beam,
push the lever toward the instrument panel. To return
to low-beam headlamps, pull the multifunction lever
toward you. Then release it.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.

During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
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
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.
