Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage your
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
There are also warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.

symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.

If a door or the trunk is opened without a key or a
remote keyless entry transmitter, the horn will sound
and the lamps will ash for about 30 seconds.
Remember, the theft-deterrent system will not arm if you
lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock with
the door open or the remote keyless entry transmitter.
To avoid activating the alarm by accident do the
following:
The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you do not want to arm the theft-deterrent system.
Always unlock a door with a key or use the remote
keyless entry transmitter system. Pressing the
unlock button on the remote keyless entry
transmitter disables the theft-deterrent system.
Unlocking a door any other way will activate
the alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter system, or by starting the car with a valid key.
Changes or modications made to this system by other
than an authorized service facility could void
authorization to use the theft system.
Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock or the
remote keyless entry system and close the
door. Wait 30 seconds until the SECURITY lamp
goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the hazard lights will ash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers on
page 5-108. If the fuse does not need to be replaced, you
may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.
