When a wrench icon appears on the instrument panel of a 2011 Honda Odyssey, it indicates that the vehicle is due for an oil change. The percentage displayed alongside the wrench icon (in this case, 15 percent) represents the remaining oil life. When the oil life reaches 0%, the wrench icon will turn solid and the "Maintenance Required" message will be displayed.
To reset the oil life reminder, follow these steps:
1. Turn the engine off.
2. Press and hold the "OK" button on the steering wheel until the maintenance menu appears.
3. Use the steering wheel controls to select "Oil Life Reset".
4. Press the "OK" button again to confirm the reset.
The wrench icon and "Maintenance Required" message will now disappear.
