Theft-Deterrent Systems
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.
Theft-Deterrent System
Your vehicle may have a theft-deterrent system.
The theft-deterrent system will not arm when you lock
the doors using the key or the manual door lock. It
activates only when you use the optional remote keyless
entry transmitter.
Arming the System
To arm the system, do the following:
1. Turn the key to LOCK and remove the key from the
ignition.
If the key is inserted in the ignition, the transmitter
will not operate the theft-deterrent system.
2. Close the doors, the windows, the hood, and the
trunk or liftgate.
Make sure the windows are closed, as the system
can be activated even if the windows are open.
3. Lock the door using the remote keyless entry
transmitter. The transmitter must be used to activate
the theft-deterrent system.
•The LED on the transmitter will flash once.
•All of the doors will lock.
•The hazard warning lamps will flash once and
the horn will chirp.
•The theft-deterrent mode will activate.
•The security light will flash once every second to
indicate that the theft-deterrent system is armed.
The security light is located on the base of
the driver’s door lock.

If your vehicle has this feature, the switch is located
between the map lamp buttons. The sunroof will
only operate when the ignition is turned to ON. The
sunroof can be opened to a vent position or it can be
express-opened all of the way.
You must manually open and close the sunroof cover.

Theft-Deterrent Feature
The theft-deterrent system is designed to discourage
theft of your radio. When the radio and vehicle are
turned off, your radio has a blinking red light to indicate
that the theft-deterrent system is activated.
The theft-deterrent system also activates when the
audio system has been disconnected from the battery.
When this occurs, the AF code and security code
will have to be entered in order to operate your radio.
An identification card stamped with the AF code
and security code will be provided with the vehicle.
Keep it in a safe place, not in the vehicle.
To enter the security code do the following:
1. Turn the ignition to ACC or ON.
2. Turn the radio on. AF or COdE will flash on the
display. If AF flashes on the display, go to Step
2. If COdE flashes on the display, go to Step 4.
3. Enter the AF code by using the preset pushbuttons.
COdE will flash on the display.
4. Enter the security code by using the preset
pushbuttons. When the complete security code is
entered, the code will flash three times.If the security code is not entered correctly, Err will
appear on the display for a few seconds. When
COdE appears back on the display, repeat Step 4.
If the incorrect AF code is entered, an incorrect
frequency level may be chosen and the radio
reception may be affected. If this occurs, reset the
audio system by removing and re-installing the
AUDIO fuse. See “Instrument Panel Fuse Block”
underFuses and Circuit Breakers on page 5-83for
more information. Then repeat Steps 1 through 4.
Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise.
FM
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.

Winter Driving
Here are some tips for winter driving:
•Have your vehicle in good shape for winter.
•You may want to put winter emergency supplies in
your trunk.
Also seeTires on page 5-51.Include an ice scraper, a small brush or broom, a
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight, a red
cloth and a couple of reflective warning triangles. And, if
you will be driving under severe conditions, include a
small bag of sand, a piece of old carpet or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.

{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
