This may cause severe engine damage. NOTE l qFuel Gauge The fuel gauge shows approximately how much fuel is remaining in the tank when the ignition switch is in the ON position. 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. The display of the variable red zone in the tachometer changes according to the temperature of the engine coolant. 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. qEngine Coolant Temperature Gauge The engine coolant temperature gauge shows the temperature of the engine coolant. l Low fuel warning light NOTE After refueling, it may require some time for the needle to stabilize. In addition, the needle may deviate while driving on a slope or curve since the fuel moves in the tank.
