2007 CADILLAC ESCALADE EXT turn signal bulb

Holding the turn signal lever for more than
one second will cause the turn signals to ash
until you release the lever. The lever will return
by itself when it is released.
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 will
not see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check for burned-out bulbs and
a blown fuse. SeeInstrument Panel Fuse
Block on page 510andUnderhood Fuse Block
on page 513.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. SeeDIC Warnings and Messages on
page 248. 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.

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.
Driving On Grades
Reduce speed and shift to a lower gearbefore
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.
You can tow in DRIVE (D). You may want to shift
the transmission to THIRD (3) or, if necessary,
a lower gear selection if the transmission shifts too
often (e.g., under heavy loads and/or hilly
conditions).
You may also want to activate the tow/haul mode
if the transmission shifts too often. See “Tow/Haul
Mode” earlier.
When towing at high altitude on steep uphill
grades, consider the following: Engine coolant at
or near sea level will boil at a lower temperature
than at higher altitudes. If you turn your engine off
immediately after towing at high altitude on
steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let
the engine run while parked (preferably on
level ground) with the automatic transmission in
PARK (P) for a few minutes before turning
the engine off. If you do get the overheat warning,
seeEngine Overheating on page 422.
