Subaru Legacy BN/BS (2015-2019) Owners Manual: Immobilizer

The immobilizer system is designed to prevent an unauthorized person from starting the engine. Only keys registered with your vehicle's immobilizer system can be used to operate your vehicle. This system, however, is not a 100% anti-theft guaranty.

For models with "keyless access with push-button start system": If you press the push-button ignition switch when carrying an unregistered access key, the switch will not turn to the "ON" position and the engine will not start.

If the engine does not start, perform the procedure described in "Starting engine" .

For models without "keyless access with push-button start system": Even if an unregistered key fits into the ignition switch and can be turned to the "START" position, the engine will automatically stop after several seconds.

If the engine does not start, pull out the key once before trying again. Refer to "Ignition switch (models without pushbutton start system)" .

NOTE

•  To protect your vehicle from theft, please pay close attention to the following security precautions:

•  Never leave your vehicle unattended with its keys inside.
•  Before leaving your vehicle, close all windows and the moonroof, and lock the doors (all models) and rear gate (Outback).
•  Do not leave spare keys or any record of your key number in the vehicle.

•  The vehicle has a maintenance-free type immobilizer system.
