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

Turn and Lane Change Signals

Headlamp High/Low
-Beam Changer

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 located 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 you move the lever all the way up or down, and the
arrow flashes at twice the normal rate, a signal bulb
may be burned out and other drivers may not 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 a blown
fuse (see ªFuses and Circuit Breakersº in the Index).

2-30 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 located on the
instrument panel cluster
also will be on.
Windshield Wipers
You control the windshield
wipers by turning the knob
with the wiper symbol on it.For a single wiping cycle, turn the knob to MIST. Hold
it there until the wipers start, then let go. The wipers will
stop after one cycle. If you want more cycles, hold the
knob on MIST longer.
You can set the wiper speed for a long or short delay
between wipes. Use this setting in light rain or snow.
Turn the knob to choose the delay time. The closer to
LOW, the shorter the delay.
For steady wiping at low speed, turn the knob to the LOW
position. For high
-speed wiping, turn the knob further,
to HIGH. To stop the wipers, turn the knob to OFF.
Damaged wiper blades may prevent you from seeing
well enough to drive safely. To avoid damage, be sure to
clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, carefully
loosen or thaw them. If your blades do become
damaged, get new blades or blade inserts.
Heavy ice or snow can overload your wipers. The
windshield wiper motor is protected from overload by a
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. Although protected from electrical overload,
overload due to heavy snow, etc. may cause wiper
linkage damage. Always clear ice and heavy snow from
the windshield before using your windshield wipers.

Turn the knob clockwise to the parking lamp symbol, to
turn on the following:

Parking Lamps

Sidemarker Lamps

Clearance Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights
Turn the knob clockwise again to the master lighting
symbol to turn on all the lamps listed as well as
the headlamps.
Turn the knob counterclockwise, to OFF, to turn off
your lamps.
You can turn your headlamps from high to low beams
by pulling on the turn signal/multifunction lever.
Headlamps On Reminder
A tone will sound when your headlamps are turned on
and the key is turned to OFF, LOCK or ACCESSORY.
If you need to use your headlamps when the key is
turned to OFF, LOCK or ACCESSORY, the buzzer can
be turned off by turning the thumbwheel next to the
parking lamp/headlamp knob all the way down.
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. Fully
functional daytime running lights are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come on
at a reduced brightness when the following conditions
are met:

the ignition is on,

the headlamp switch is off and

the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When it begins to get dark, your DRL indicator light is a
reminder to turn your headlamp knob on. The other lamps
that come on with your headlamps will also come on.

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.
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.
