Distance Control Switch Circuit |
DESCRIPTION
The vehicle-to-vehicle distance control switch is used to set the distance for vehicle-to-vehicle distance control mode. The vehicle-to-vehicle distance control switch is installed in the steering pad switch assembly. The vehicle-to-vehicle distance set value can be changed by operating the vehicle-to-vehicle distance control switch while the dynamic radar cruise control system is controlling vehicle speed in vehicle-to-vehicle distance control mode.

- When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.
-
If the forward recognition camera has been replaced with a new one, be sure to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust.
