Subaru Solterra 2023-2026 Owner's Manual: If a warning message is displayed

The multi-information display of the Subaru Solterra provides important alerts related to system malfunctions, incorrect operations, and maintenance requirements. These messages are designed to help the driver quickly identify and respond to potential issues.

If a warning message is displayed together with a warning light or indicator, always address both alerts accordingly, as they may indicate a more serious condition.

■ Warning messages

The specific wording and appearance of warning messages in the Subaru Solterra may vary depending on driving conditions, system status, and vehicle configuration.

■ Warning buzzer

In certain environments, such as noisy surroundings or when the audio system is active, the warning buzzer in the Subaru Solterra may be difficult to hear. Always monitor visual indicators as well.

■ If "EV system stopped Steering Power low" is displayed

This message indicates that the EV system in the Subaru Solterra has shut down while the vehicle is in motion.

As a result, steering assistance will be reduced, making the steering wheel heavier to operate.

Maintain a firm grip on the steering wheel and apply additional effort to control the vehicle safely.

■ If "EV system overheated Output power reduced" is displayed

This warning may appear when the Subaru Solterra is driven under demanding conditions, such as prolonged uphill driving or high load situations.

To protect system components, output power may be temporarily limited until normal operating temperatures are restored.

■ If "Shift System Malfunction Shifting Unavailable Drive to a Safe Place and Stop" or "Shift System Malfunction Driving Unavailable" is displayed

This indicates a malfunction in the shift control system of the Subaru Solterra.

Stop the vehicle in a safe location and have it inspected immediately by a SUBARU dealer.

■ If "Shift is in N Release Accelerator before shifting" is displayed

This message appears when the accelerator pedal is pressed while the Subaru Solterra is in Neutral (N).

Release the accelerator pedal before shifting into Drive (D) or Reverse (R).

■ If "Press brake when vehicle is stopped EV system may overheat" is displayed

This warning may occur when the accelerator pedal is used to hold the vehicle stationary, such as on an incline.

To prevent overheating in the Subaru Solterra, release the accelerator and press the brake pedal instead.

■ If "Auto Power OFF to Conserve Battery" is displayed

This message indicates that the Subaru Solterra has automatically powered down to protect the 12-volt battery.

When restarting the EV system, operate the vehicle for several minutes to allow the battery to recharge sufficiently.

■ If "Regenerative Braking Limited Press Brake to Decelerate" is displayed

Regenerative braking in the Subaru Solterra may be limited under the following conditions:

In such cases, apply the brake pedal firmly to slow down the vehicle.

• When the traction battery is fully charged and cannot accept additional energy
• When the traction battery temperature is extremely high or low
• When the electric motor or power control unit temperature is elevated

■ If "High Power Consumption Power to Climate Temporarily Limited" is displayed

This message indicates that energy consumption in the Subaru Solterra is high, and climate system output may be temporarily restricted.

Switch off unnecessary electrical devices and wait for system conditions to stabilize.

■ If "Headlight System Malfunction Visit Your Dealer" is displayed

This warning suggests a malfunction in one or more lighting systems of the Subaru Solterra.

Possible affected systems include:

• LED headlight system
• Automatic High Beam system

Have the Subaru Solterra inspected by a SUBARU dealer as soon as possible.

■ If "Parking Assist Unavailable Sensor Blocked" is displayed

This message indicates that one or more sensors on the Subaru Solterra may be obstructed by dirt, snow, ice, or water.

Clean the sensors to restore normal operation.

In cold weather, temporary ice buildup may also trigger this warning. Once the ice melts, the system will resume normal function.

If the issue persists despite clean sensors, professional inspection is required.

■ If "Parking Assist Unavailable Low Visibility See Owner's Manual" is displayed

This message indicates that certain assistance systems in the Subaru Solterra are temporarily unavailable due to poor visibility conditions.

• RCD (Rear Camera Detection) (if equipped)
• PKSB (Parking Support Brake)
