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
Flash-to-Pass Feature
Windshield Wipers
Windshield Washer
Cruise Control
For information on the exterior lamps, seeExterior
Lamps on page 3-14later in this section.
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.
If you move the lever all the way up or down, and the
arrow ashes at twice the normal rate, a signal bulb may
be burned out and other drivers may not see your
turn signal.
3-8

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 or a blown fuse.
SeeFuses and Circuit Breakers on page 5-102.
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
23
(Headlamp High/Low Beam Changer):To
change the headlamps from low to high beam, pull the
mutlifunction lever all the way toward you. Then
release it.
When the high beams are
on, this light on the
instrument panel cluster
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 and stay on as long
as you hold the lever toward you and the high-beam
indicator on the instrument panel 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.
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.
(Delay):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.
3-9

The headlamps can be switched from high to low-beam
by pulling the turn signal/high-beam lever
A circuit breaker protects the headlamps. If there is an
electrical overload, the headlamps will icker on and
off. Have the headlamp wiring checked right away if this
happens.
Lamps On Reminder
A reminder chime will sound when the control is turned
to the headlamps or parking lamps position, the key
is out of the ignition, and the driver’s door is open.
To disable the chime, turn the control to the DRL
position and then back to the parking lamps or
headlamps position.
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 lamps are required on all vehicles
rst sold in Canada.The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in the DRL mode and
not in the defeat position.
When the DRL are on, only the headlamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will be lit.
When the headlamp switch is turned off, the headlamps
will go off, and the DRL lamps will come on.
Turn the exterior lamp control to the defeat position or
shift into PARK (P). The DRL will stay off until the control
is turned to the defeat position, or the vehicle is shifted
out of PARK (P).
This procedure applies only to vehicles rst sold in the
United States.

Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
Since you can not 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 are 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
are driving, do not 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 re-adjust to the dark. When
you are faced with severe glare (as from a driver
who does not 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 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 is 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
are not even aware of it.
