Title: CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: Distance Control Switch Circuit; 2018 MY Camry [03/2017 - 06/2017]

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:

  • 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. 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.
