To install the Range V8, simply plug the device into the vehicle OBD II port under the steering wheel. The vehicle should always be fully off when installing the device. Once installed, the blue light should illuminate.
You can leave the Range device in the vehicle all the time if the vehicle is driven regularly. If it is driven sporadically, please remove the device and reinstall when ready to drive.
Always remove your device before visiting your automotive dealership. The technicians at the dealership will need access to the OBD II port in order to run diagnostics on your vehicle.
