 Take that moment, get in your vehicle and push the button or turn the key. And if you're pushing the button, do it without your foot on the brake so it doesn't start. And watch what happens. Look at the dash lights that come on. Understand what the dash lights are that come on. We call that bulb check. They're cycling bulbs to make sure things light up so you can tell if, hey, one's not lit. How do you know the vehicle's overheating if the overheat bulb is out, right?
