Horn
To sound the horn, press the horn symbols on the
steering wheel pad.
Tilt Wheel
You should adjust the
steering wheel before you
drive. The tilt lever is
located to the left of the
steering column, under the
turn signal lever.
You can 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 toward you. Move the steering wheel to a
comfortable level, then release the lever to lock the
wheel in place.
Do not adjust the steering wheel while driving.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
·G:Turn and Lane Change Signals
·2:Headlamp High/Low-Beam Changer
·Flash-to-Pass Feature
·N:Windshield Wipers
·J:Windshield Washer
·I: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 ®nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ¯ash 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 ¯ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it. The bottom of the outside
rearview mirrors may also be equipped with lane change
indicators.
As you signal a turn or a lane change, if the arrows
¯ash more quickly than normal, 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. SeeFuses and Circuit Breakers
on page 5-90and check for burned-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal ¯asher is
used. With this ¯asher installed, the signal indicator will
¯ash even if a turn signal bulb is burned out. Check
the front and rear turn signal lamps regularly to make
sure they are working.
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 ¯ash 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, push
the lever toward the instrument panel. To return to
low-beam headlamps, pull the multifunction lever toward
you. Then release it.
3-8

When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
Flash-to-Pass
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, then
release it.
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.
The high-beam indicator on the instrument panel
cluster will come on. Release the lever to return to
normal operation.
Windshield Wipers
8
(Mist):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.
9(Off):To stop the wipers, move the band to off.
N(Windshield Wipers):Turn the band to control the
windshield wipers.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain
or snow. Turn the band to choose the delay time. The
closer to the top of the lever, the shorter the delay.
For steady wiping at low speed, turn the band away from
you to the ®rst solid band past the delay settings. For
high-speed wiping, turn the band further, to the second
solid band past the delay settings. To stop the wipers,
move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.

Fog Lamps
Your vehicle may have this feature. Use your fog lamps
for better vision in foggy or misty conditions. Your
ignition must be in RUN for your fog lamps to work.
The fog lamp button is
located on the instrument
panel to the right of
the exterior lamps knob.
Press the button to turn the fog lamps on. Press the
button again to turn them off. A light will glow near the
button while the fog lamps are on. Fog lamps will
turn off whenever your high-beam headlamps are on.
Interior Lamps
Instrument Panel Brightness
Press the knob located
next to the exterior lamps
knob to extend it.
Turn the knob to adjust the instrument panel lights. Turn
the knob all the way up to turn on the interior lamps.
Press the knob back into its stored position when you're
not using it.

Here are some tips on night driving.
·Drive defensively.
·Don't drink and drive.
·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.
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 Ð 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 ®lm caused by dust. Dirty glass makes
lights dazzle and ¯ash 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 Ð the inability to see in dim light Ð and
aren't even aware of it.
