Subaru Ascent 2018-2026 Owner's Manual: Auto Vehicle Hold indicator light

CAUTION

If the Auto Vehicle Hold indicator light in your Subaru Ascent does not activate after selecting "Auto Vehicle Hold (AVH)", this may indicate a potential issue with the electronic parking brake system. In such cases, the system may not function as intended, and it is recommended to have your Subaru Ascent inspected by an authorized SUBARU dealer as soon as possible to ensure proper operation and safety.

In the Subaru Ascent, the Auto Vehicle Hold indicator light illuminates when the AVH system is successfully enabled. This system is designed to maintain the vehicle in a stationary position without the driver needing to continuously press the brake pedal. While the Subaru Ascent is being held in place by the Auto Vehicle Hold function, the indicator light will blink, clearly signaling that the system is actively engaged. For a more detailed explanation of system behavior and conditions of use, refer to the "Auto Vehicle Hold function" section in the Subaru Ascent manual.

Low fuel warning light

The low fuel warning light in the Subaru Ascent turns on when the fuel level drops to approximately 2.6 US gallons (10.0 liters, 2.2 Imp gallons). This warning appears only when the ignition switch is in the "ON" position and serves as an early alert to prevent the fuel tank from running empty.

CAUTION

It is important to refuel your Subaru Ascent promptly once the low fuel warning light is illuminated. Continuing to drive with insufficient fuel can lead to engine misfires, which may result in engine damage and reduced reliability over time.

Door open warning light

The door open warning light in the Subaru Ascent illuminates whenever any door or the rear gate is not completely closed. This safety feature operates regardless of the ignition switch position, including "LOCK"/"OFF" or "ACC", and even when the key has been removed.

Depending on the configuration of your Subaru Ascent, the system may display which specific door is open, allowing the driver to quickly identify and correct the issue.

Before starting your journey, always confirm that this warning light is not illuminated to ensure all doors and the rear gate are securely closed, maintaining proper cabin safety and preventing unexpected openings.

Engine hood open warning light

The engine hood open warning light activates in the Subaru Ascent if the hood is not properly closed and secured. This function remains active even when the ignition is in the "LOCK"/"OFF" or "ACC" position, or when the key is removed (for models without keyless access with push-button start system).

Always verify that the hood of your Subaru Ascent is fully latched before driving. An unsecured hood can obstruct visibility if it opens unexpectedly, creating a serious hazard while driving.

All-Wheel Drive warning light

The All-Wheel Drive warning light in the Subaru Ascent may begin flashing if the vehicle is operated with tires of different diameters or if one or more tires are significantly underinflated. These conditions can negatively affect the AWD system's ability to distribute torque evenly between wheels.

To maintain optimal performance of the Subaru Ascent AWD system, always ensure that all tires are of the same size, type, and wear level, and that they are inflated to the recommended pressure. Prompt correction of any irregularities helps preserve drivetrain integrity and ensures stable, predictable handling in various driving conditions.

Keeping a close eye on indicator lights in the Subaru Ascent and reacting to them without delay contributes to smoother vehicle operation, better fuel efficiency, and increased safety during both short city trips and extended highway driving.

WARNING

If the AWD warning light in your Subaru Ascent begins to flash, you should immediately bring the vehicle to a safe stop and inspect all four tires. Carefully verify that all tires are of identical size and diameter, and check for any signs of puncture, damage, or significant air pressure loss.

Continuing to operate your Subaru Ascent while the AWD warning light is flashing may place excessive strain on the drivetrain and can result in serious powertrain damage over time.

NOTE

If a temporary spare tire is installed on your Subaru Ascent, the AWD warning light may flash as a normal response. Since the temporary spare tire differs in size and performance characteristics, its use should be limited strictly to short distances. Replace it with a standard tire as soon as possible to restore proper AWD system functionality and maintain balanced driving performance.

Power steering warning light

In the Subaru Ascent, the power steering warning light will illuminate while the engine is running if the system detects a malfunction in the electric power steering mechanism. This alert indicates that the steering assist system may not be functioning at its optimal level.

CAUTION

When the power steering warning light is illuminated in your Subaru Ascent, you may notice increased resistance when turning the steering wheel. This can make steering more difficult, especially at lower speeds. Drive cautiously and proceed to the nearest SUBARU dealer to have the system inspected and repaired without delay.

NOTE

Under certain driving conditions, the power steering control system in the Subaru Ascent may temporarily reduce steering assist in order to protect key components such as the control unit and electric motor from overheating.

• This may occur if the steering wheel is turned repeatedly and rapidly at very low speeds, for example during frequent maneuvering or tight parking situations.
• It can also happen if the steering wheel is held at its maximum turned position for an extended period.

During these situations, you may feel increased resistance in the steering wheel. This is a protective function and not a malfunction of the Subaru Ascent. Normal steering assist will return once the system has had time to cool down and the steering input is reduced. However, repeatedly placing excessive strain on the steering system in this way may eventually lead to wear or potential malfunction, so it is advisable to operate the steering smoothly and avoid unnecessary strain.

Maintaining proper tire condition and avoiding extreme steering inputs will help ensure that the Subaru Ascent continues to deliver stable handling, predictable steering response, and long-term reliability across a wide range of driving environments.
