Tilt Wheel (If Equipped)
The tilt steering wheel
allows you to adjust the
steering wheel before
you drive.
You can also raise it to the highest level to give your
legs more room when you enter and exit the vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever. Move the steering wheel to a comfortable level,
then release the lever to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes your:

Turn Signal and Lane Change Indicator

Headlamp High/Low Beam Changer

2-46 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 beams
are on, this light on the
instrument panel also
will be on.
Flash-To-Pass Feature
This feature allows you to 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 off.
To use it, pull the turn signal lever toward you, but not
so far that you hear it 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 instrument cluster will come on. Release
the lever to turn the high
-beam headlamps off.
Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
For a single wiping cycle, turn the band to MIST. Hold
it there until the wipers start, then let go. The wipers will
stop after one wipe. If you want more wipes, hold the
band on MIST longer.

To idle an automatic transmission equipped vehicle with
the DRL off, set the parking brake. Shifting the
transmission into PARK (P) will also allow you to idle
the vehicle with the DRL off. The DRL will stay off
until you release the parking brake or shift the
transmission out of PARK (P).
To idle a manual transmission equipped vehicle with the
DRL off, set the parking brake. The DRL will stay off
until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps (If Equipped)
If you have fog lamps, use them for better vision in
foggy or misty conditions. Your parking lamps and/or
low
-beam headlamps must be on for your fog lamps
to work.
The fog lamp switch is on
the left side of your
instrument panel.
Press the switch to turn the fog lamps on. Press the
switch again to turn them off. An indicator light will
glow in the switch when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.

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'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.

4-34 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.
