How do I read the tachometer?

The tachometer is located on the left side of the instrument panel, and displays how fast your engine is moving. The tachometer is a semicircle with numbers on it, which correspond to the revolutions per minute (RPM) of your engine. While you are driving, the tachometer needle will move, representing the speed (x 1,000) of your engine. Tips You should not rev your engine such that the needle is in the red zone of the tachometer.
