T INSTRUMENT CLUSTER INSTRUMENT CLUSTER STRUCTURAL VIEW 1. Speedometer 2. Tachometer 3. Water temperature gauge 4. Fuel gauge 5. Oil pressure gauge 6. Warning and indicator lights 7. Trip meter 8. Odometer DESCRIPTION Speedometer Two scales are shown on the speedometer face. The main scale for U.S. specification vehicles is MPH (0-140 MPH); the main scale for Canada specification vehicles is kmlh (0-220 kmlh). The odometer indication is the same as the main scale. Tachometer The tachometer has a RED STRIPED ZONE (6,500-7,000 rpm) that indicates momentary allowable engine speed. The engine should not be operated in the RED ZONE (7,000-8,000 rpm). Fuel Gauge 2 The fuel gauge continues to indicate the amount of fuel remaining in the fuel tank after the ignition switch has been turned OFF. Gartner Banana
