Turn Signal/Multifunction Lever
The lever located on the left side of the steering column
includes the following:

Turn and Lane Change Signals

Headlamp High/Low
-Beam Changer

Flash
-To-Pass Feature
For information on the exterior lamps, see ªExterior
Lampsº later in this section.
Turn and Lane-Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow located on the
instrument panel cluster
will flash in the direction
of the turn or lane change.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it is released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON after driving about a mile to
remind you to turn it off.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned
-out signal bulb.
Other drivers won't see the turn signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs
if the arrow fails to work when signaling a turn.

4-39 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 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
still working.
