Dashboard warning lights are your car's way of communicating with you. Here are a few key ones: **Check Engine Light:** This could mean anything from a loose gas cap to a serious engine issue. Get it checked by a mechanic. **Oil Pressure Warning:** This light looks like an oil can. Stop the car immediately and check your oil level. Driving with low oil pressure can severely damage the engine. **Battery/Charging Alert:** Shaped like a battery, this light indicates a problem with your car's charging system, which could be the battery or the alternator. **Tire Pressure Warning (TPMS):** This means one or more of your tires is significantly under-inflated. Pull over when safe and check your tire pressures.
