Subaru Crosstrek Owners Manual: To arm the system using power door locking switches

1. Close all windows.

2. Remove the key from the ignition switch (models without "keyless access with push-button start system")/turn the push-button ignition switch to the "OFF" position (models with "keyless access with push-button start system").

3. Open the doors and get out of the vehicle.

4. Make sure that the engine hood is locked.

5. Close the doors (and the rear gate) but leave only the driver's door or the front passenger's door open.

6. Press the front side ("LOCK" side) of the power door locking switch to set the door locks.

7. Close the door. An electronic chirp will sound once, the hazard warning flashers will flash once and the security indicator light will start flashing rapidly. After rapid flashing for 30 seconds (standby time), the indicator lights will then flash slowly (twice approximately every 2 seconds), indicating that the system has been armed for surveillance.
