HAC is the controller unit which controls the degree of throttle opening via accelerator pedal

Acceleration from zero-start as well as from high speed cruising will be improved.

Undesirable hesitaiton you experience at start of stepping down on the pedal will be diminished and quick response is always available

When the engine is turned off, HAC is also turned off. When you restart the engin, HAC will not be engaged unless HAC Power Switch is depressed.

 

HAC modifies normal signal from Accelerator Sensor and transmit the control signal as if wider throttle opening is given. This will enhance the response and solve the hesitation at zero-start or acceleration from the cruising speed!
