Instead of trying to reset a light, you should address the underlying problem.
Here's what you should do:
1. Check your oil level: Use the dipstick to check your oil level. If it's low, add the correct type and amount of oil recommended in your owner's manual.
2. Check for oil leaks: Inspect your engine for any signs of oil leaks. Look for drips or stains under the vehicle.
3. If the oil level is correct and you still see the light: This indicates a more serious problem, possibly with the oil pump, oil pressure sensor, or other engine components. Do not drive the vehicle. Have it towed to a qualified mechanic for diagnosis and repair. Continuing to drive with a low oil pressure light on will likely cause significant engine damage.
The low oil pressure light cannot simply be "reset" like a service reminder light. It's a critical warning indicator. The light will usually go off once the oil pressure is restored to a safe level *after the underlying cause has been fixed*.
If you're referring to a service reminder light (sometimes displayed as an oil can icon), the reset procedure will vary depending on the year. Consult your owner's manual for the precise steps for your specific model year. The manual will give you instructions typically involving a sequence of steps using the instrument cluster buttons.
