BASIC ASCD SYSTEM
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at a predetermined constant speed
without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/
h (25 MPH) and 144 km/h (89 MPH).
VCM controls the traction motor to regulate vehicle speed.
Operation status of ASCD is indicated on the information display in the combination meter. If any malfunction
occurs in ASCD system, it automatically deactivates control.
