2. Low fuel warning
What it looks like: An anthropomorphic 1950s-era gas pump, scratching its head in confusion, often with an arrow.
What it means: You should fill up sometime in the near future, within the next 50 miles or so. Or, if you're a rocket scientist, just stop in the middle of the road, immediately. Either way, the arrow points to the side of the car with the gas cap.
3. Water temperature warning
What it looks like: An upper case E, hung at half mast on a flag pole in the middle of the ocean.
What it means: Your car's coolant is getting pretty hot. Get yourself to the side of the road -- or better yet, to a parking lot -- as quickly as possible, or you risk overheating your engine.
4. Low oil pressure warning
What it looks like: Your afternoon tea is ready.
What it means: Your oil pressure is too low. The biggest takeaway is to get off the road, because there's not enough oil lubricating your pistons, and your engine doesn't like chafing any more than you do.
