Distance Control Switch Circuit

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

DESCRIPTION

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