Hi -- I find your post both interesting and scary, since we just (3-7-14) bought a loaded 2014 C-MAX SEL with push button start. We bought it primarily for it's alleged flat towing capability.
I sold our previous tow car/tow bar and will be taking our C-MAX to Camping World this week to have a tow bar installed. Now I'm having second thoughts!
I would like to ask you a few questions if you don't mind:
1. Do you put the ignition in the "Off" position when you tow? On page 183 of my Owner's Manual, it first says to "place the ignition in the off position." Then, after explaining what to do at the beginning of each day, it says to place the ignition "in the accessory position." I think this is probably a typo.
2. Why do you connect a trickle charger to the C-MAX while towing? Does the 12 volt battery go dead?
3. Where in the manual did you find the information about using a trickle charger? What kind of trickle charger do you use, and how do you connect it from your RV to the C-MAX?
4. Do you know if I could use a battery disconnect switch on the C-MAX while towing, like I did on the Saturn tow car?
Please keep us posted on what you find out about the Advanced Traction Control warning light.
Thanks!
