Driving Your Mazda Instrument Cluster and Indicators CAUTION Don't run the engine with the tachometer needle in the RED ZONE. This may cause severe engine damage. NOTE l qFuel Gauge The fuel gauge shows approximately how much fuel is in the tank. We recommend keeping the tank over 1/4 full. When the low fuel warning light illuminates or when the needle is near E, refuel as soon as possible. l The beep sounds to indicate engine overrev when the tachometer needle enters the striped zone. To protect the engine, when the engine coolant temperature is low, the engine does not run at high speeds. The fuel supply will be cut at an rpm lower than the red zone. Low fuel warning light qEngine Coolant Temperature Gauge The engine coolant temperature gauge shows the temperature of the engine coolant. NOTE The direction of the arrow ( ) shown that the fuel-filler lid is on the left side of the vehicle. qEngine Oil Pressure Gauge If the needle is near H, it indicates overheating. CAUTION Driving with an overheated engine can cause serious engine damage (page 7-16). Engine oil pressure is normal when the engine oil pressure gauge needle points halfway between L and H with the engine running. 5-36
