RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational (RV) towing.
An example of recreational towing would be towing your vehicle behind
a motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
Note: Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle.
