do you watch the warning lights every time after you start the engine?
yes?
honestly?
every time?
you should do.
nobody starts the engine and watch the lights before start rolling.
if you do this, if any light goes on, if you dont know what is telling, you have to have the manual handy and learn what it means. it may save you the aggravation and lots of money !
you dont need to find yourself in the position when some light was telling you that you should do something and you didnt and then something went wrong, and you could prevent this to happen.
engineers have spent long time designing this system for your convenience. we are lucky to have them. then, take advantage of this. use it.
