Subaru Solterra 2023-2026 Owner's Manual: Parking Support Brake function (static objects front and rear of the vehicle/static objects around the vehicle)

Within the Subaru Solterra, the Parking Support Brake system continuously monitors the driving path for stationary obstacles such as walls or fixed structures. If the sensors detect a static object and the system determines that a collision could occur — for example due to unintended acceleration, incorrect gear selection, or low-speed maneuvering — it automatically intervenes to limit impact severity and help minimize potential damage.

Examples of function operation (static objects front and rear of the vehicle)

This intelligent Subaru Solterra safety feature becomes active in various real-world situations when a stationary object is detected directly in the vehicle’s path.

■ When traveling at low speed and braking is insufficient or delayed

■ When excessive accelerator input is applied

■ When unintended forward movement occurs due to incorrect gear selection

Examples of function operation (static objects around the vehicle) (Vehicles with Advanced Park)

For Subaru Solterra models equipped with Advanced Park, the system also analyzes surrounding areas and intervenes when a collision risk with nearby stationary objects is detected.

■ When moving forward and a collision risk exists on the inner side of a turn

■ When reversing and a collision risk exists on the outer side of a turn

■ The Parking Support Brake function (static objects front and rear of the vehicle) will operate when

The Subaru Solterra system activates when the driving assist indicator is not illuminated and all of the following criteria are satisfied:

• EV system output restriction control
  • The Parking Support Brake system is switched ON.
  • The Subaru Solterra is traveling at approximately 9 mph (15 km/h) or less.
  • A stationary object is detected approximately 6 to 13 ft. (2 to 4 m) ahead or behind.
  • The system determines that stronger braking than usual is required to avoid impact.
• Brake control
  • EV output restriction is already active.
  • The Subaru Solterra determines that immediate braking intervention is necessary.

■ The Parking Support Brake function (static objects around the vehicle) will operating when (Vehicles with Advanced Park)

For Subaru Solterra vehicles equipped with Advanced Park, the system becomes active when the above conditions are met along with any of the following:

• The vehicle has traveled approximately 23.0 ft. (7 m) or less after startup
• The shift position is set to R
• After switching from R to D, the vehicle has moved within approximately 23.0 ft. (7 m)

■ The Parking Support Brake function (static objects front and rear of the vehicle/static objects around the vehicle) will stop operating when

The Subaru Solterra system disengages under the following circumstances:

• EV system output restriction control
  • The Parking Support Brake is turned OFF.
  • The system determines that normal braking is sufficient to avoid collision.
  • The detected object is no longer within the critical 6 to 13 ft. (2 to 4 m) range.
• Brake control
  • The system is disabled.
  • Approximately 2 seconds have passed since the Subaru Solterra stopped.
  • The driver presses the brake pedal after stopping.
  • The detected object is no longer within the critical range or path.

■ Detection range of the Parking Support Brake function (static objects front and rear of the vehicle/static objects around the vehicle)

The Subaru Solterra Parking Support Brake operates within a detection range that differs from the SUBARU Parking Assist system. This means that even if Parking Assist issues a warning, the braking system may not activate depending on distance, angle, and system judgment.

■ Situations in which the system may operate even though there is no possibility of a collision (static objects around the vehicle) (vehicles with Advanced Park)

Under certain driving conditions, particularly with Advanced Park in the Subaru Solterra, the system may respond even when no actual collision risk exists. This is due to sensor interpretation limitations and environmental factors.

• When moving laterally, such as during parallel parking maneuvers

■ Detection of objects along the sides of the vehicle (static objects around the vehicle) (vehicles with Advanced Park)

• The Subaru Solterra does not instantly recognize side obstacles. Instead, it builds an estimated map of surrounding objects after detecting them via side sensors or cameras. Therefore, immediately after startup, objects beside the vehicle may not be detected until the system completes a scan during initial movement.
• If an object such as a vehicle, pedestrian, or obstacle leaves the detection zone after being identified, the Subaru Solterra system may temporarily assume that it remains stationary in its last known position.

The Subaru Solterra integrates advanced sensor fusion and predictive logic to improve low-speed safety, but drivers should always remain attentive and ready to intervene when maneuvering in tight environments.
