Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving
over high points on the road or over
road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's better not to park with the engine running. But if
ever you have to, here are some things to know.
CAUTION:
Idling the engine with the climate control system
off could allow dangerous exhaust into your
vehicle (see the earlier Caution under
ªEngine Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard. (See
ªBlizzardº in the Index.)

CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº in
the Index.
Locking Rear Axle
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the time,
but when one of the rear wheels has no traction and the
other does, this feature will allow the wheel with
traction to move the vehicle.
Windows
Manual Windows
To operate your manual windows, turn the hand crank
on each door to raise or lower your side door windows.
Power Windows (Option)
If you have the optional power windows, the controls
are on each of the side doors.

The driver's door has a switch for the passenger
windows as well. Your power windows will work when
the ignition has been turned to RUN.
Push the rear of the switch with the power window
symbol on it to lower the window.
Push the front of the switch with the power window
symbol on it to raise the window.
The driver's window switch also has an express
-down
feature that allows the window to lower without holding
the switch. Press and hold the side of the window switch
marked AUTO for one second to activate the
express
-down mode. The express-down mode can be
cancelled at any time by pressing the opposite side of
the switch. To open the window part way, lightly tap the
switch until the window is at the desired position.
Swing-Out Windows
Side Swing-Out Window
To open your side door swing
-out windows, pull up on
the latch at the edge of the window and swing the
window out and push down the latch into the locked
open position.
To close the window, pull the latch toward you and push
down on the latch to lock it.

Rear Swing-Out Window
Your rear swing
-out windows work the same way, but
the latch is at the bottom edge of the window.
CAUTION:
It can be dangerous to drive with the rear
swing
-out windows or rear door(s) 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 rear swing-out
windows or rear door(s) open or if electrical
wiring or other cable connections must pass
through the seal between the body and the rear
swing
-out windows or rear door(s):

Make sure all windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT, HEAT, BLEND or DEF.
Additionally, on vehicles with heating/air
conditioning systems, NORM A/C or
BI
-LEVEL A/C can be used. 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.

Horn
Press the horn symbol in the middle of the steering
wheel to sound the horn.
Tilt Wheel (Option)
A 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 Changer

Headlamp High/Low
-Beam Changer

Windshield Wipers

Windshield Washer

Cruise Control (Option)

yellowblue
2-34 Turn Signal 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 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.As you signal a turn or a lane change, if the arrows flash
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).
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, 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.

2-35 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 cycle. If you want more cycles, hold the
band 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 band to choose the delay time. The
closer to LOW, the shorter the delay.For steady wiping at low speed, turn the band to the
LOW position. For high
-speed wiping, turn the band
further, to HIGH. 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 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 or ice the wiper will stop until the motor
cools. Although the circuit is protected from electrical
overload, overload due to heavy snow or ice may cause
wiper linkage damage. Always clear ice and heavy snow
from the windshield before using your windshield wipers.

2-36 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 approximately two more wipe cycles and
then either stop or return to the preset speed.
Cruise Control (Option)
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When you apply your brakes or move the cruise switch
to OFF, the cruise control shuts off.
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.
