To lock the power lock system from the outside, insert

All doors will lock.
Also, see the Caution following ªHatch,º located in
this section.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transmission. Also remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's best to lock it up and take your keys.
But what if you have to leave your key? Do not leave
valuables in your vehicle, since there is no locking area
in which to secure them. Lock all doors except
the driver's.
Passlock

Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will go
off approximately five seconds after the key is turned to
the RUN ignition position.

Ignition Positions
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be injured or even killed. They could
operate power windows or other controls or even
make the vehicle move. Don't leave the keys in
the vehicle with children.
Use your ignition key to start your vehicle. The
ignition key lets you turn the ignition switch to five
different positions.ACCESSORY (A): This position lets you use things
like the radio and the windshield wipers when the
engine is off. To get into ACCESSORY, push in the key
and turn it toward you. Your steering wheel will remain
locked, just as it was before you inserted the key.

Parking Over Things That Burn
CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things that
can burn.
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.

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.
All-Wheel Drive (Option)
If your vehicle has
all
-wheel drive, your
engine's driving power is
sent to all four wheels for
extra traction when needed.
This is like four
-wheel drive, but there is no separate lever
or switch to engage or disengage the front axle. It is fully
automatic, and adjusts itself as needed for road conditions.
You may experience a brief vehicle vibration upon
acceleration when driving in slippery conditions. This is
normal and is an indication that the all
-wheel drive
system is functioning properly.
Windows
Manual Windows
To open your manual windows, turn the hand crank on
each door to raise or lower your side door windows.
Power Windows (If Equipped)
If you have the optional power windows, the controls
are on each of the front side doors. The driver's door has
a switch for the front passenger window as well. Your
power windows will not move unless the ignition has
been turned to RUN or ACCESSORY.

Express-Down Window
The driver's window switch also has an express
-down
feature that allows you to lower it without holding the
window switch. Press and hold the side of the driver's
window switch down marked AUTO for one second to
activate the express
-down feature. The express-down
feature can be interrupted at any time by pressing the up
arrow end of the switch. Lightly tap the switch to open
the window slightly.
Swing-Out Windows
To open your swing-out
windows, pull up on the
latch and push the
window out.
To close the window, pull the latch toward you and push
it down.
CAUTION:
It can be dangerous to drive with the rear
swing
-out windows, rear hatch 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 rear swing-out
windows, rear hatch or rear doors open or if
electrical wiring or other cable connections
must pass through the seal between the body
and the rear swing
-out windows, rear hatch 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 anything but MAX A/C. 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.

2-33 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 wipe. If you want more wipes, 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 away
from you to LOW. For high
-speed wiping, turn the
band further, to HIGH. To stop the wipers, turn 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.
Windshield Washer
At the top of the multifunction lever, there's a
paddle marked with the windshield washer symbol and
PUSH. To spray washer fluid on the windshield, press
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.
The wipers will clear the window and then either stop or
return to your preset speed.

2-34
Rear Window Washer/Wiper (Option)
You control your rear
window washer/wiper
from a switch on your
instrument panel, next to
the audio system.
To turn the wiper on, slide the switch all the way up.
For delay wiping, slide the switch even with the word
DELAY in the center position of the rear wiper control.
The wiper will cycle every nine seconds.
To wash the window, push in on the switch. Window
washer fluid will continue to spray until the switch is
released. The wiper will continue with three more wipes
and then return to the setting that was chosen before the
lever was pushed.
The rear window washer uses the same fluid bottle as
the front windshield washer. If the fluid level is low inthe washer bottle, you may not be able to wash your rear
window. If you can wash your windshield, but not your
rear window, check the fluid level.
Cruise Control (If Equipped)
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, 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.
