To reset the 2013 Acura RL 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 on the steering wheel 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, then press the SEL/RESET button to reset the engine oil life display. The maintenance item code(s) will disappear, and the engine oil life will reset to 100. 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).
