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

Turn and Lane Change Signals

Headlamp High/Low Beam Changer

Flash
-to-Pass

Windshield Wipers

Windshield Washer

Cruise Control (If Equipped)
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 (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs.

Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the turn
signal. 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 to high beam or high
to low beam, pull the multifunction lever all the way
toward you. Then release it.
When the high-beam
headlamps are on, this
indicator 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.
It works even if your headlamps are in the
automatic position.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are in the automatic position 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.

2-43 Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps or low
-beam headlamps
must be on for your fog lamps to work.
The fog lamp switch is on the instrument panel under
the lamps switch. Press the switch to turn the fog lamps
on. Press the switch again to turn them off. A light will
glow in the switch when the fog lamps are on.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high
-beam headlamps
go off, the fog lamps will come on again.
Interior Lamps
Brightness Control
Turn the thumbwheel next to the headlamp switch up to
make your instrument panel lights brighter. Turn the
thumbwheel all the way up to turn on the interior lamps.
Illuminated Entry
Your vehicle is equipped with an illuminated
entry feature.
When the doors are opened, the dome lamps will come
on if the DOME OVERRIDE button is in the ªoutº
position. When all the doors are closed, or the front door
handles are lifted and released, the lamps will stay on
for a short period of time and will turn off automatically.
If you use your keyless entry transmitter to unlock the
vehicle, the interior lights will come on for a short time
whether or not the DOME OVERRIDE button is in the
ªoutº position.

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're
driving, 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.

4-30 Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you're
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn't happen often. But it can if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops ªdimpleº the
water's surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn't a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine's air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody of your vehicle. If you
can't avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips

Turn on your low-beam headlamps -- not just
your parking lamps
-- to help make you more visible
to others.

Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.

Have good tires with proper tread depth.
