CRUISE CONTROL DYNAMIC RADAR CRUISE CONTROL SYSTEM(for Gasoline Model) 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.

CAUTION / NOTICE / HINT
- NOTICE:
- ·
Before replacing the ECM, refer to the Service Bulletin.
·The vehicle is equipped with a Supplemental Restraint System (SRS) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the precaution for Supplemental Restraint System.

·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 and a DTC may be stored.
·When the forward recognition camera is replaced with a new one or the windshield glass is replaced or removed/installed, make sure to perform beam axis adjustment for the forward recognition camera and clear the vehicle control history for each system.
- HINT:
-
Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.
