Adjusting the set Speed

< Vehicle-to-vehicle distance control mode >

  1. Adjusting to a lower speed

    The set speed can be decreased 5 mph (For USA) or 5 km/h (For Canada) by pressing the control lever downward in the "- SET" direction and releasing it within 0.5 seconds.

    If the control lever is held down in the "- SET" direction however, the set speed will decrease gradually and continuously in steps of 5 mph (For USA) or 5 km/h (For Canada) as long as the switch is held down. But you cannot decrease the speed to below the lower speed limit of about 27 mph (For USA) or 43 km/h (For Canada). If the preset speed is changed, the vehicle speed will gradually be decreased to the set speed.

  2. Adjusting to a faster speed

    The set speed can be increased 5 mph (For USA) or 5 km/h (For Canada) by pressing the control lever upward in the "+ RES" direction and releasing it within 0.5 seconds.

    If the control lever is held down in the "+ RES" direction however, the set speed will increase every gradually and continuously in steps of 5 mph (For USA) or 5 km/h (For Canada) as long as the switch is held down. But you cannot increase the speed to above the upper speed limit. If the set speed is changed, the vehicle speed will gradually be increased to the set speed.

    * If the distance control mode is active, and the control lever is pressed upward in the "+ RES" direction, the vehicle speed will not be increased but the set speed will be changed.

< Conventional cruise control mode >

  1. Deceleration

    * If the cruise control is active and the control lever is held downward in the "- SET" direction, the vehicle speed will gradually decrease. When you release it, the vehicle speed will be set at that speed. If the control lever is released while the vehicle speed exceeds the upper limit of the set speed, such as when traveling downhill, the system will store the upper speed limit of the set speed as the set speed.

    * When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed will be decreased in steps of 1.6 km/h (1 mph) each time the control lever is pressed downward in the "- SET" direction and released within 0.5 seconds. But if the control lever is released when the difference between the actual vehicle speed and the set speed is more than 5 km/h (3 mph), then the set speed will be set to the current vehicle speed.

  2. Acceleration

    * If the cruise control is active and the control lever is held upward in the "+ RES" direction, the vehicle speed will gradually increase. When you release it, the vehicle speed will be set at that speed. If the vehicle speed exceeds the upper limit of the preset speed while you are pressing the control lever downward, the system will cruise at the upper limit of the set speed. And if the control lever is released, this will set the vehicle speed at that speed.

    * When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed will be increased in steps of 1.6 km/h (1 mph) each time the control lever is pressed upward in the "+ RES" direction and released within 0.5 seconds. But if the control lever is released when the difference between the actual vehicle speed and the set speed is more than 5 km/h (3 mph), then the set speed will be set to the current vehicle speed.

    * If the control lever was being pressed downward, and was then released when the vehicle speed had been increased by pressing the acceleration pedal, the system will store the current vehicle speed as the set speed. But if the control lever is operated downward when the vehicle speed is already greater than the upper limit of the set speed, then the speed cannot be set.
