I learned many years ago, from my brother who was a jet engine mechanic in the Air Force then a commercial pilot on 747's, when you first turn your key and watch all your lights turn on, then actually starting the engine, how many of you actually read all the lights? It's a crucial part of driving a car and the majority of folks pay no attention to any lights or indicators other than the fuel level (maybe not even that!) or maybe the seat belt light. Those lights are there for a reason. You paid good money for a computer system in your car to monitor, diagnose and indicate a problem where necessary. I just want to remind everyone to take the four seconds or so and watch those lights when you start your car. Also crucial are the many bits of information given to us by the DIC, i.e., tire pressure, voltage output of battery, engine coolant temp, etc.
