Keys and doors CAUTION In passive mode, the system will automatically activate the alarm but WILL NOT automatically lock the doors. In order to lock the doors you must either lock them as indicated in step 4 above or with the key once they have been closed. Failure to lock the doors manually will result in a higher security risk. B Disarming the system To disarm the system, briefly press the "UNLOCK/ DISARM" button on the transmitter. n Tripped sensor identification If the horn sounds four times and the parking lights flash four times when you disarm the system, this indicates that the alarm was triggered. The number of times the indicator light flashes indicates what sensor caused the alarm condition. To enter identification mode: 1. Open the driver's door and leave it open. 2. Turn the ignition switch to the "ON" position two times. ("LOCK" → "ON" → "LOCK" → "ON" → "LOCK") 3. The indicator light will start flashing. 3. Open the doors and get out of the vehicle. 4. Before closing the doors, lock all doors with the inside door lock levers. 5. Close the doors. The system will automatically arm after one minute. In the passive mode, the system can also be armed with the remote transmitter or with the power door locking switches. If the remote transmitter or power door lock switch is used to lock the vehicle, arming will take place immediately regardless of whether or not the passive mode has been selected. 2-20
