Note: The Car2U system allows for three devices to be programmed. If
you need to change or replace any of the three devices after it has been
initially programmed, it is necessary to erase the current settings using
the Erasing the Car2U Home Automation System buttons procedure
and then programming all of the devices being used.
Fixed code programming
Note: Do not program the Car2U system with the vehicle in the garage.
Make sure that your key is on and engine off while programming the
transmitter.
