ASCD BASIC SYSTEM


CAUTION:
If ASCD is used, driving safety should be given the highest priority in any event.
- ASCD (automatic speed control device) enables the driver to drive the vehicle at a constant speed with the acceleration pedal released once he a desired vehicle speed is set. *
*: The driver can select a desired vehicle speed in a range from approximately 40 km/h (25 MPH) to 144 km/
h (90 MPH).
- HPCM controls engine and traction motor output and adjusts vehicle speed to match the set speed. In addition, HPCM transmits an ASCD status signal to the combination meter and the information display displays the operation status. (Automatic Speed Control Device (ASCD) Switch Name and Function.)
- If a non-standard condition is detected during ASCD control, the ASCD control is cancelled automatically.
