Interesting, I an just setting one up as a toad. Mine is an sel and the manual says start it in the morning and let it run one minute. You may have to press the accelerator to get the engine to start according to the manual.
One thing mentioned in forums is the 12v battery running down after a couple of hours. I bought the Toad Charger from lsl and installed it power supplied through the 6 prong connector for the lights and both the circuit breaker and the charger (tiny) under the hood. Ground wire to the same place you see the others near the battery in the c-max. For the power I just opened the cover on the side under the + jump point of the battery and connected it the same place one of the other wires is connect to and the cover back on. Electrical on both vehicles protected that way and the battery stays charged.
Disclaimer (there's always one isn't there) I have not towed it distance, just local to get a feel for it but had no issues with that.
Headed out next month with it in tow for a trip. Also gonna have a clear bra put on it in Houston while we are there .for added protection. I had one on on the Murano we traded in and loved it. That had over 100k miles just driving and it was well protected, even with all the stinking grasshoppers. We live in the country. Figured being towed the C-Max would be a good thing have even though I have a rock guard on the mh.
Wow, long winded there...
