The low oil light means your engine is at serious risk of damage. Here's what to do:
1. Immediately stop driving the car. Continuing to drive with a low oil light can cause catastrophic engine failure.
2. Check the oil level. Use the dipstick to determine if the oil is truly low. If it is low, add oil of the correct type and viscosity (check your owner's manual).
3. Check for leaks. Inspect the engine for any visible oil leaks. Look underneath the car as well.
4. If the oil level was low and you added oil, start the engine and let it run for a few minutes. If the light goes out, you likely had low oil. Monitor the oil level regularly. If the light comes back on, there's a more serious issue.
5. If the oil level was fine, or if the light stays on after adding oil, the problem is likely with the oil pressure sensor or the oil pump itself. This requires professional attention. Do not continue driving.
In short: Addressing the reason the light came on, not simply resetting a light, is crucial for protecting your engine. Take your car to a qualified mechanic to diagnose and repair the problem.
