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 RKE 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 flash. You can turn off the alarm by unlocking the driver's door with your key, using the unlock button on the RKE 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, see Fuses and Circuit Breakers on page 5-95. 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.
