Installation Of Radio System
- If a radio system is installed improperly or if a high-powered type is used, the CIS and other systems may be affected. When the vehicle is to be equipped with a radio, observe the following precautions:
- Install the radio set and its antenna as far away as possible from the control module and control unit.
- The antenna feeder and power cable to generate radio waves, therefore, keep them 100 mm or more from the control module, control unit, and wiring harness. If the antenna feeder and power cable cross over the wiring harness, place them perpendicular to the wiring harness.
- Do not install a high-powered radio system.
- Do not use the control module and control unit power source for the radio set. In addition, do not use the cigar lighter as an accessory socket power source.
- Do not attach the antenna feeder or wiring harness of the radio set to the wiring harness, fuel pipe, or brake tube of the vehicle.
- Do not install any radio set-related devices in the area where the air bag module deploys to prevent a secondary accident if the air bag were to deploy.

- After installing the radio set, perform a test transmission with the engine idling to verify that it does not affect engine control.
