Checking Oil Level
- Park on a level surface. Ensure your vehicle is on a flat area for accurate readings.
- Open the hood. Locate the hood release lever inside the car, usually on the driver’s side.
- Find the dipstick. Look for the yellow or orange handle, typically near the engine.
- Pull the dipstick out. Wipe it clean with a cloth, then reinsert it fully.

Clearing The Light Using Diagnostic Tools
- Connect the OBD-II scanner. Locate the OBD-II port under the dashboard near the driver’s seat, and plug in your scanner.
- Turn on the ignition. Switch the ignition to the “on” position without starting the engine.
- Access the scanner menu. Follow the prompts on the scanner to read diagnostic trouble codes (DTCs).
- Clear the codes. Select the option to clear or erase trouble codes. Confirm when prompted.
- Disconnect the scanner. Unplug the scanner from the OBD-II port once the codes are cleared.
