We purchased a new 2009 Ford Escape XLT 4WD on August 1. It came with a "RECREATIONAL (FLAT) TOWING AND TRANSMISSION FLUID LEVEL SUPPLEMENT". It replaces the recreational towing and the checking automatic transmission fluid sections of the owners manual.
The supplement was first printed in June 2009. The only number I see on it is 9L8J 19A285 AA.
It shows examples of the dip sticks used and shows exactly where the fluid levels should be. It also warns to have your fluid level checked for flat towing by an authorized Ford dealer. This should be done before you tow.
