Content Theft-Deterrent
Your vehicle has a content theft-deterrent alarm
system.
This is the security light.
To activate the theft-deterrent system, do the
following:
1. Open the door.
2. Lock the door with the remote keyless entry
(RKE) transmitter. The security light should
come on and stay on.
3. Close all doors. The security light should go
off after about 30 seconds. The alarm is not
armed until the security light goes off.
If a locked door is opened without using the RKE
transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash.If the door is not unlocked by pressing the unlock
button on the remote keyless entry transmitter
during the ten second pre-alarm, the alarm will
go off. The headlamps and parking lamps will ash
for two minutes, and the horn will sound for
30 seconds, then will turn off to save the battery
power. You can choose different feedback options
for the alarm. SeeDriver Information Center
(DIC) on page 244Driver Information Center (DIC).
Remember, the theft-deterrent system will not
activate if you lock the doors with a key, the
manual door lock, or the power door lock switch.
It activates only if you use the RKE transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm
has been set off.

Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door key after the doors are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off
the alarm.
If you set off the alarm by accident, turn off the
alarm by pressing the unlock button on the
RKE transmitter. The alarm will not stop if you try
to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.While the alarm is set, the power door unlock
switch will not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 538.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by
your dealer.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair or
replacement. Paying attention to your warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they
are working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together
to let you know when there is a problem with your
vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to do
repairs can be costly – and even dangerous.
So please get to know your warning lights and
gages. They are a big help.
Your vehicle also has a Driver Information Center
(DIC) that works along with warning lights and
gages. SeeDIC Warnings and Messages
on page 252.
