yellowblue 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 transmitter and close the door. Wait 30 seconds until the SECURITY light goes off. 3. Reach in and unlock the door using the manual lock and open the door. The horn will sound and the headlamps will flash. 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, see "Fuses and Circuit Breakers" in the Index. If the fuse does not need to be replaced, you may need to have your vehicle serviced. To reduce the possibility of theft, always activate the theft-deterrent system when leaving your vehicle. Valet Lockout Button Pressing the VALET lockout button located inside the glove box to ON will disable the use of the power trunk, fuel door and garage door openers. Pressing this button again will make these features reusable. Locking the glove box with the door key will also help to secure your vehicle. Note: The remote keyless entry transmitter can't be used to open the trunk or fuel door if the VALET lockout button is in the ON position. 2-16
