2008 CADILLAC CTS turn signal bulb

Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster ashes in the
direction of the turn or
lane change.
Raise or lower the lever until the arrow starts to ash
to signal a lane change. Hold it briey until the lane
change is complete. The arrow will automatically ash
three times The lever returns to its original position when
it is released.
Rapid ashing of arrows when signaling for a turn or
lane change can be caused by a burned-out signal bulb.
Other drivers will not see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse for burned-out bulbs if the
arrow fails to work when signaling a turn. SeeFuses and
Circuit Breakers on page 5-123for more information.
Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km),
a warning chime will sound and the TURN SIGNAL ON
message will appear on the Driver Information Center
(DIC) display. See “Turn Signal On” underDIC Warnings
and Messages on page 3-56for more information.
Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever to
change the headlamps from low to high beam. Pull the
lever back and then release it to change from high
to low beam.
If the vehicle is turned off while the high beams are on,
they will come on the next time the vehicle is started.
The highbeam light on the
instrument panel cluster,
comes on while the
high-beam headlamps
are on.

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 are turning with a trailer, make wider turns
than normal. Do this so your trailer will not 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 a
different turn signal asher and/or extra wiring. Check
with your dealer/retailer. 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 are 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
is important to check occasionally to be sure the trailer
bulbs are still working.
