Accel Control

If the cruise control switch is held to the + RES side while driving in cruise control mode, the device recognizes the cruise control is on the acceleration side and gradually accelerates the vehicle. When the switch is released, the device stores the current vehicle speed. From then on, the vehicle is controlled to stay at that speed.

Every time the switch is pressed to the + RES side momentarily (For about 0.5 seconds), the set speed is increased by about 1.6 km/h. However, if the switch is pressed multiple times and attempts to put the set speed more than 5kmh above the actual vehicle speed, the device will not change the set speed. (Tap-up operation is not available.)
