125.Dinghy towing Do not use your parking brake when there is a possibility it could freeze. When parking, put the selector lever into "P" and block the rear wheels. Do not use the parking brake, or snow or water accumulated in and around the parking brake mechanism may freeze, making it hard to release. Keep ice and snow from accumulating under the fenders. Ice and snow built up under your fenders can make steering difficult. During bad winter driving, stop and check under the fenders occasionally. Depending on where you are driving, we recommend you carry some emergency equipment. Some of the things you might put in the vehicle are tire chains, window scraper, bag of sand or salt, flares, small shovel, jumper cables, etc. Trailer towing126. 40p050 40p003a Your vehicle is not designed to be dinghy towed (with four wheels on the ground) behind a motorhome.
