How do I read the tachometer?

A: The tachometer is on the left side of your ...

The tachometer is on the left side of your instrument control panel, and tells how quickly the engine is moving. The tachometer measures your engine speed in terms of revolutions per minute (rpm). The tachometer is a semicircle, with the numbers 1 through 8 on it, and a needle that moves as the engine speed changes. For example, when the tachometer needle is pointing at the 2, that means that the engine is operating at 2,000 rpm. The red area on the tachometer represents the speed at which the engine should not be operating. If the tachometer needle is in the red area, make sure that a higher gear is available for your vehicle.
