includes your:

-to-Pass Feature
Turn Signal and Lane Change Indicator
The turn signal has the following positions: two upward
(for right) and two downward (for left). 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 finished, the lever will
return automatically.
An arrow on the instrument
panel cluster will flash 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 flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
If the arrow flashes 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 (see ªFuses and Circuit Breakersº in the Index).
A chime will sound if you leave your turn signal on for
more than 3/4 mile (1.2 km).
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.
When the high beams are on this light, located on the
instrument panel, will also be on.
Flash-to-Pass Feature
This feature lets you use your high-beam headlamps
to signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
To use it, pull the turn signal lever toward you a little,
but not so far that you hear a click.
If your headlamps are off or on low beam, your
high
-beam headlamps will turn on. They'll stay on
as long as you hold the lever toward you and the
high
-beam indicator on the dash will come on.
Release the lever to return to normal operation.

4-37 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
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.
