Ignition Positions
With the ignition key in the ignition switch, you can turn
the switch to five different positions.
ACCESSORY (A): In this position you can operate
your electrical power accessories. Press in the ignition
switch as you turn the top of it toward you.
LOCK (B): This is the only position from which
you can remove the key. This position locks your
ignition, steering wheel and transaxle. It's a
theft
-deterrent feature.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK and it doesn't send any electrical
power to the accessories. The instrument panel cluster
will remain powered in OFF to illuminate the gear shift
indicator. The cluster will also activate the parking brake
light when the parking brake is set. Use OFF if you
must have your vehicle in motion while the engine is
not running.

3-31 Theft-Deterrent Feature
THEFTLOCK is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
If THEFTLOCK is active, the THEFTLOCK indicator
will flash when the ignition is off.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before it will operate.
Activating the Theft
-Deterrent Feature
The instructions which follow explain how to enter your
secret code to activate the THEFTLOCK system. It is
recommended that you read through all nine steps
before starting the procedure.
If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time and
you must start the procedure over at Step 4.1. Write down any three or four
-digit number from
000 to 1999 and keep it in a safe place separate from
the vehicle.
2. Turn the ignition to ACCESSORY or RUN.
3. Turn the radio off.
4. Press the 1 and 4 buttons together. Hold them down
until
--- shows on the display. Next you will use the
secret code number which you have written down.
5. Press MIN and 000 will appear on the display.
6. Press MIN again to make the last two digits agree
with your code.
7. Press HRS to make the first one or two digits agree
with your code.
8. Press AM
-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show REP to let you know that you
need to repeat Steps 5 through 7 to confirm your
secret code.
9. Press AM
-FM and this time the display will show
SEC to let you know that your radio is secure.

Battery
Your new vehicle comes with a maintenance free
ACDelco battery. When it's time for a new battery, get one
that has the replacement number shown on the original
battery's label. We recommend an ACDelco battery.
Vehicle Storage
If you're not going to drive your vehicle for 25 days or
more, remove the black, negative (
-) cable from the battery.
This will help keep your battery from running down.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see ªTheft
-Deterrent
Featureº in the Index.
Bulb Replacement
The following procedure tells you how to replace your
headlamp bulbs. For the type of bulb to use, see
ªReplacement Bulbsº in the Index. For any bulbs not
listed in this section, contact your service department.
Halogen Bulbs
CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
