RES/ACC Position
If cruise control operation is canceled by any canceling switch, vehicle set speed can be resumed and controlled at the previously set speed by moving cruise control switch to RES/ACC (resume/accelerate) position. Set speed, however, cannot be resumed if vehicle speed drops to less than 25 MPH, which clears cruise control ECU set speed stored.
When cruise control switch is moved to RES/ACC (resume/accelerate) position while in cruise control mode, actuator motor is energized to open engine throttle valve. Vehicle accelerates until switch is released. From then on, cruise control ECU stores new vehicle speed and maintains that speed.
