Owners of a 2017 Subaru Forester understand the importance of adhering to the manufacturer's maintenance schedule, particularly when it comes to the engine. Resetting the oil life monitor after performing an oil change is a critical step that ensures the vehicle's advanced driver-assistance systems continue to provide accurate maintenance reminders. This procedure is specific to the Subaru STARLINK infotainment system and requires a precise sequence of inputs to recalibrate the sensor.
Understanding the Oil Life Monitoring System
The 2017 Subaru Forester does not rely on a fixed mileage interval for oil changes; instead, it utilizes a sophisticated Oil Life Monitor (OLM). This system analyzes the vehicle's driving habits, such as engine speed, temperature, and usage patterns, to determine the actual degradation of the motor oil. Resetting the system is essential because the dashboard alert will persist indefinitely if the new oil's condition is not registered, potentially leading to confusion about the next service date.
Preparing for the Reset Procedure
Before initiating the reset, ensure the vehicle is parked in a safe location and the parking brake is engaged. The engine must be running throughout the entire process, so have the key fob or ignition ready. It is recommended to perform the reset immediately after the oil has been drained and the new filter has been installed to ensure the system calibrates to the fresh lubricant. Having the vehicle stationary prevents any misinterpretation of sensor data during the recalibration.
Step-by-Step Reset Instructions
The process for the 2017 model requires navigating the steering wheel controls to interact with the STARLINK display. Follow these steps precisely to avoid restarting the sequence:
Turn the ignition to the "ON" position without starting the engine, or start the engine if it is already off.
Press the "DISP" button on the steering wheel until the display shows "Oil Life" or "Maintenance."
Press and hold the "ENT" (Enter) button on the steering wheel for approximately five seconds.
The screen will display "Reset Oil Life?" or a similar confirmation prompt.
Press the "ENT" button again to confirm the reset.
Wait for the system to complete the initialization, which may take a few moments.
Verification and Troubleshooting
Once the procedure is complete, the oil life percentage should reset to 100%. If the display reverts to 0% immediately upon driving or the alert icon persists, the reset may not have registered correctly. This usually requires repeating the steps, ensuring the "ENT" button is held for the full duration during both the activation and confirmation stages. Double-checking that the vehicle is in the "ON" mode during the reset is crucial for success.
Benefits of a Proper Reset
Completing this process accurately maintains the integrity of the vehicle's maintenance history. It ensures that the Subaru's EyeSight driver assist technology receives accurate data regarding the vehicle's operational status. Furthermore, staying on top of oil changes based on actual usage rather than arbitrary mileage protects the turbocharged engine's longevity and preserves the resale value of the Forester.
When to Seek Professional Help
While the reset is designed to be user-friendly, some owners may find the button sequence challenging or the display unresponsive. If repeated attempts fail to clear the oil life alert, the issue might be a faulty oil life sensor or a software glitch within the STARLINK unit. In these instances, a certified Subaru technician can diagnose the problem and perform a manual recalibration using a dealership-level diagnostic tool.
