2-38 Turn Signal and Lane Change Indicator
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.
A green 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).
Turn Signal On Chime
If you leave either one of your turn signals on and drive
more than 3/4 mile (1.2 km), a chime will sound to
alert you.
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 blue light on the
instrument panel cluster also will be on. This light
works only when the ignition key is in the ON position.
Also, your fog lamps (if equipped) will not illuminate
when your high beams are on.

4-37 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
additional 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.

Headlamp Aiming
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re
-aimed, we recommend that you
take your vehicle to the dealer for service. However, it is
possible for you to re
-aim your headlamps by following
the procedure in the service manual for your vehicle.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
