Subaru Ascent 2018-2026 Owner's Manual: Alarm system setting

The Subaru Ascent allows you to customize the alarm system by switching between activation and deactivation modes. This flexibility enables you to adapt the vehicle’s security behavior to your specific needs.

To modify the Subaru Ascent alarm system settings, follow these steps carefully:

1. First, disarm the Subaru Ascent alarm system. Refer to the section "Disarming the system" for detailed instructions.

2. Sit in the driver’s seat of your Subaru Ascent and ensure that all doors, the rear gate, and the engine hood are fully closed.

3. Turn the ignition switch to the "ON" position.

4. Press and hold the " " button on the driver’s power door locking switch. While holding the button, open the driver’s door within 1 second, and continue holding the switch for approximately 10 seconds. The Subaru Ascent system will then switch between activation and deactivation modes accordingly.

NOTE

If preferred, this Subaru Ascent alarm system configuration can also be performed by an authorized SUBARU dealer.

If you have accidentally triggered the alarm system

To stop the alarm

If the Subaru Ascent alarm system is activated unintentionally, you can stop it by performing one of the following actions:

• Press any button on the Subaru Ascent access key fob or remote transmitter.
• Turn the ignition switch to the "ON" position (for models without keyless access).
• Switch the push-button ignition to the "ACC" position (for Subaru Ascent models with keyless access).

NOTE

Only keys that are registered with the Subaru Ascent immobilizer system can deactivate the alarm. Unregistered keys will not stop the alarm system.

Valet mode

The Subaru Ascent valet mode is designed to temporarily disable the alarm system while maintaining basic remote control functions. This mode is particularly useful when handing over your vehicle to parking attendants or service personnel.

When the Subaru Ascent is in valet mode, the alarm system remains inactive. However, the remote transmitter can still be used for:

• Locking and unlocking doors
• Opening the rear gate
• Activating the panic alarm

To enable valet mode in your Subaru Ascent, switch the alarm system to deactivation mode using the procedure described above. The security indicator light will flash once every 3 seconds, confirming that valet mode is active.

To exit valet mode, simply reactivate the Subaru Ascent alarm system by switching it back to activation mode.
