How Does Maintenance Minder System Work?

To help you stay ahead of maintenance and prevent issues before they happen, the Acura Maintenance Minder operates continuously as you drive your vehicle. It’s able to monitor engine operating conditions and helps you coordinate oil service dates along with other maintenance check-ups. The system displays engine oil life on the information screen to tell the driver when it’s the appropriate time to have the oil replaced and regular engine maintenance completed. This oil life indicator shows a percentage which gradually lowers over time as the mileage begins to add up. Speed, engine temperature, ambient air temperature, time, and vehicle use are factors used in determining oil life. Below, you’ll find a chart which explains what each oil life percentage means.
