Outline

• To prevent air from flowing into the fuel line when fuel in the fuel tank decreases, the output is intentionally controlled to warn the user to supply fuel.

Operation

• The PCM controls the engine output according to the fuel consumption amount after turning fuel gauge segments off (point E).

*1 :For fuel gauge point E, refer to the [FUEL GAUGE]. (See FUEL GAUGE.)

*2 :When accelerating, the engine output is suppressed by controlling the fuel injection amount.

*3 :Vibration of the vehicle body occurs due to the intermittent fuel cut.

*4 :If the engine is restarted, driving is possible after approx. 20 s have elapsed.
