He should read his owners manual under "Recreational Towing" for the specifics but the short answer is YES. There is a sequence to use when getting ready to tow but no modifications other than the hitch and wiring are required to the vehicle. We have towed our MKT for over a year now. These are some of the few vehicles factory supported for recreational towing.

Last time I looked, was thinking about one of these or MKZ, AWD can NOT be towed 4 down or 2 down but as previous poster stated read his owner's manual. It will not only tell him if possible but also any requirements or limitations.
