CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: Distance Control Switch Circuit
- Distance Control Switch Circuit

DESCRIPTION

The distance control switch sets the vehicle-to-vehicle distance control mode. The vehicle-to-vehicle distance set value can be changed by operating the cruise distance switch assembly (distance control switch) while the dynamic radar cruise control system is in operation.
