Speedometer and Odometer The speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). The odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). NOTICE: Do not operate the engine with the tachometer in the red area or engine damage may occur. Engine Speed Limiter This feature prevents the engine from operating at too many revolutions per minute (rpm). When the engine's rpm are 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. Trip Odometer The trip odometer tells how far you have driven since you last reset it. To set it to zero, press the knob located below the speedometer on the instrument panel cluster. Tachometer This gage indicates the engine speed in revolutions per minute (rpm). 2-65
