Tachometer The tachometer is located in the instrument panel cluster, to the left of the speedometer. Engine Speed Limiter This feature prevents the engine from operating at too many revolutions per minute (rpm). When the engine's rpm is critically high, the fuel supply to the engine is shut off. When the engine speed slows, the fuel supply will come on again. This helps prevent damage to the engine. Warning Lights, Gages and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle's functions. As you will see in the details on the next few pages, some warning lights come on briefly when you start the engine just to let you know they're working. If you are familiar with this section, you should not be alarmed when this happens. NOTICE: Do not operate the engine with the tachometer in the shaded area or engine damage may occur. This gage indicates the engine speed in revolutions per minute (rpm). 2-66
