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 finished, the lever will
return automatically.
An arrow on the instrument
panel 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.
As you signal a turn or a lane change, if the arrows don't
flash but just stay on, 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 the fuse and check for burned
-out
bulbs. See ªFuses and Circuit Breakersº in the Index.
Turn Signal Reminder
If your turn signal is left on for more than 3/4 of a mile,
a chime will sound. To turn off the chime, move the turn
signal lever to the off position.
Headlamp High/Low Beam Changer
To change the headlamps from low beam to high or high
to low, pull the turn signal lever toward you until you
hear a click. Then release it.
When the high beams are
on, this light on the
instrument panel will also
be on.
Flash-To-Pass Feature
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
To use it, pull the turn signal lever toward you a little,
but not so far that you hear a click.
Your high
-beam headlamps will stay on as long as you
hold the lever toward you. The high
-beam indicator on
the dash will also come on. Release the lever to turn the
high
-beam headlamps off.

4-37 Turn Signals When Towing a Trailer
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.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle's lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they're all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gear before 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.
On a long uphill grade, use the highest gear possible.
If you cannot maintain posted speeds, driving at a
lower speed may help avoid overheating your engine
and transaxle.
Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
