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.

Interior Courtesy Lamps
Pull the knob toward you to the first setting to turn on
the parking lamps and other operating lamps without the
headlamps. Pull the knob toward you to the second
setting to turn on the headlamps as well as the other
operating lamps.
Turn the knob from left to right to control brightness of
the instrument panel lights.
Lamps On Reminder
If the headlamp switch is left on, you'll hear a warning
chime when you turn the ignition off, remove the key
from the ignition and open the driver's door.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
The DRL system will make your high
-beam headlamps
come on at reduced brightness in daylight when:

the ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).
When DRL are on, only your high
-beam headlamps will
be on. The parking lamps, taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't
be lit up either.
When it's dark enough outside, your high
-beam
headlamps will turn off and your low
-beam and parking
lamps will become active. The other lamps that come on
with your headlamps will also come on. When it's bright
enough outside, the regular lamps will go off, and your
high
-beam headlamps change to the reduced brightness
of DRL.

Here are some tips on night driving.

Drive defensively.

Don't drink and drive.

Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.

Since you can't see as well, you may need to
slow down and keep more space between you and
other vehicles.

Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.

In remote areas, watch for animals.

If you're tired, pull off the road in a safe place
and rest.
Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50
-year-old
driver may require at least twice as much light to see the
same thing at night as a 20
-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes will
have less trouble adjusting to night. But if you'redriving, don't wear sunglasses at night. They may cut
down on glare from headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When you
are faced with severe glare (as from a driver who
doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and aren't
even aware of it.

To remove the air cleaner assembly, see Steps 1 through
3 earlier in this section. See ªAir Cleanerº in the Index.The passenger's side high-beam headlamp access area is
next to the radiator pressure cap.
The passenger's side low
-beam headlamp access area is
to the right and slightly behind the high beam area.
The driver's side high
-beam headlamp access area is
located near the air cleaner.

The driver's side low-beam headlamp access area
is behind and between the high
-beam area and the
air cleaner.
1. Loosen the two bolts on the inboard edge of the
headlamp assembly. This allows you to pull out
the assembly for more hand clearance when
changing bulbs.
2. Reach into the assembly
and turn the bulb socket
one
-quarter of a turn
toward the center of the
engine compartment,
while pressing it firmly.
3. Remove the wire connector from the bulb by
lifting the lock tab (B) and pulling it away from the
plastic base.
4. Install the bulb by putting the small tab (D) into the
small notch in the lamp (E).5. Turn the bulb socket one
-quarter of a turn making
sure the tab is properly engaged in the panel slot.
6. To reassemble, attach the wire connector (A) to the
plastic base making sure the lock tab (B) is over the
lock (C).
7. Replace the headlamp assembly and tighten the two
bolts on the inboard edge of the assembly.
Headlamp Aiming
Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre
-set at the factory and should need no further
adjustment. This is true even though your vertical and
horizontal aim indicators may not fall exactly on the ª0º
(zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment 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 it to your dealer
for service; however, it is possible for you to re
-aim
your headlamps as described in the following procedure.
