To reset the 2011 Acura MDX maintenance light, please follow these instructions:
1. Turn the ignition to (II) – do not start the engine.
2. Press the SEL/RESET button on the steering wheel repeatedly until engine oil life is displayed.
3. Press and hold the SEL/RESET button for more than 10 seconds. The remaining engine oil life reset mode will be shown on the multi information display.
4. Select RESET by pressing the INFO (up/down) button
5. Turn the ignition off and then start the engine to verify the indicator has been reset.
*Models equipped with the keyless access system have an engine start/stop button instead of an ignition switch. Pushing start/stop button once without starting engine is equivalent of ignition (II).
