SUBARU SOLTERRA OWNER’S MANUAL

If the electronic key does not operate properly

2023–2026 manual reference · Features may vary by model and market.

If communication between the electronic key and the Subaru Solterra is disrupted, or if the key cannot be used due to a depleted battery, the smart key system and wireless remote functions will be unavailable. In such situations, the Subaru Solterra can still be accessed and started by following the alternative procedures outlined below.

■ When the electronic key does not work properly

  • Confirm that the smart key system of the Subaru Solterra has not been disabled in the customization settings. If it is turned off, reactivate the function to restore normal operation.
  • Check whether battery-saving mode is enabled on the electronic key. If active, disable this mode to allow proper communication with the Subaru Solterra.

NOTICE

■ In case of a smart key system malfunction, or other key related problems

If the issue persists, bring your Subaru Solterra along with all provided electronic keys to an authorized SUBARU dealer for inspection and diagnosis.

Locking and unlocking the doors

When the electronic key is not functioning, use the mechanical key included with your Subaru Solterra to manually operate the door locks.

WARNING

■ When using the mechanical key and operating the power windows

Before operating the windows using the mechanical key in the Subaru Solterra, ensure that no passenger has any part of their body in the window path. Never allow children to operate the key, as this may result in injury due to window entrapment.

Starting the EV system

1. Fully depress the brake pedal in the Subaru Solterra.

2. Hold the electronic key close to the power switch.

Once the Subaru Solterra detects the key, an audible signal will sound and the power switch will transition to the ON mode.

If the smart key system is disabled via customization settings, the power mode will switch to ACC instead.

3. Continue pressing the brake pedal firmly and confirm that Subaru Solterra ready indicator icon on display is shown on the multi-information display.

4. Press the power switch briefly and firmly to start the Subaru Solterra EV system.

If the Subaru Solterra still fails to start after completing these steps, contact your SUBARU dealer for further assistance.

■ Stopping the EV system

To turn off the Subaru Solterra, shift the gear selector to P, engage the parking brake, and press the power switch as you would during normal operation.

■ Replacing the key battery

Since the above method is only a temporary workaround, it is strongly recommended to replace the electronic key battery of your Subaru Solterra as soon as possible to restore full functionality.

■ Alarm

If the Subaru Solterra is unlocked manually using the mechanical key while the alarm system is armed, the alarm may activate. This is a normal security response.

■ Changing power switch modes

Release the brake pedal and press the power switch as described in step 3 above.

The Subaru Solterra EV system will remain off, and each press of the switch will cycle through the available power modes.
