CAUTION:
It can be dangerous to drive with the tailgate
glass, tailgate or rear doors open because carbon
monoxide (CO) gas can come into your vehicle.
You can't see or smell CO. It can cause
unconsciousness and even death.
If you must drive with the tailgate glass, tailgate
or rear doors open or if electrical wiring or other
cable connections must pass through the seal
between the body and the tailgate glass, tailgate
or rear doors:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting on
VENT. That will force outside air into your
vehicle. See ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Tailgate Glass and Tailgate
If your vehicle has a tailgate, you must raise the rear
glass before lowering the tailgate.
To open the glass from the outside, use your key. With
the key in the lock, turn the key clockwise to release the

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

Windshield Wipers

Windshield Washer

Cruise Control
Turn Signal and Lane Change Indicator
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.
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 ªFusesº in the Index).

2-41 Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, pull the turn signal 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.
Windshield Wipers
You operate the windshield
wipers by turning the
control with the wiper
symbol on it.
For a single wiping cycle, turn the control to MIST.
Hold it there until the wipers start, then let go. Thewipers will stop after one cycle. If you want more
cycles, hold the control on MIST longer.
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 control to choose the delay time. The
closer to LOW, the shorter the delay.
For steady wiping at low speed, turn the control to the
LOW position. For high
-speed wiping, turn the control
further, to HIGH. To stop the wipers, turn the control
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 snow or ice 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 the circuit is 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.

2-42 Windshield Washer
At the top of the lever,
there's a paddle with the
word PUSH on it. To spray
washer fluid on the
windshield, push the paddle.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
Washer fluid will spray as long as you push the paddle.
When you let go of the paddle, the wipers will continue
to wipe for a few seconds and then either stop or return
to the preset speed.
The use of hood
-mounted air deflectors may adversely
affect windshield wiper and washer performance.
Rear Window Wiper and Washer
The rear window
wiper/washer switch is on
your instrument panel, to
the right of the gage cluster.
To turn the wiper on, slide the switch all the way up.
For delay wiping, slide the switch even with DELAY in
the center position of the rear wiper control. The wiper
will cycle every nine seconds.

2-47 Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start the vehicle. The automatic headlamp
system will stay off until you release the parking brake.
The headlamp switch can always be used to turn on the
regular lamps. As with any vehicle, you should turn on
the regular headlamp system when you need it.
Headlamps-On Reminder
A chime will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY.
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.The DRL system will make your headlamps come on at
a reduced brightness when:

the ignition is on,

the headlamp switch is off,

the parking brake is released and

it is bright enough outside and the automatic
headlamps are off.
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 will turn off. Your
headlamps will come on automatically.
When it begins to get bright, the regular lamps will go
off, and your headlamps will change to the reduced
brightness of DRL.
To idle your 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.

2-48 Fog Lamps
Your vehicle has 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
located to the right of the
instrument panel cluster.
Press the ribbed top part of the switch to turn the fog
lamps on. Press the bottom of the switch to turn them
off. An indicator light will illuminate 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.Fog lamps will go off whenever your high
-beam
headlamps come on. When the high
-beams are off, the
fog lamps will come on again.
Headlamp Delay
Your vehicle is equipped with a headlamp delay feature
that holds the headlamps on for a short period of time
after the ignition is turned off.
The HEADLAMP DELAY button is located on the
lower left side of the inside rearview mirror.
