ADVANCED DRIVER ASSISTANCE SYSTEM  DYNAMIC RADAR CRUISE CONTROL SYSTEM(for NR Series Engine)  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 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, 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.

·

If the forward recognition camera has been replaced with a new one, it is necessary to perform forward recognition camera adjustment.

HINT:

Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.
