Release the regular brakes. Maintenance When Trailer Towing Your vehicle will need service more often when you are pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle fluid (do not overfill), engine oil, drive belt, cooling system and brake system. Each of these is covered in this manual, and the Index will help you find them quickly. If you are trailering, it is a good idea to review this information before you start your trip. Check periodically to see that all hitch nuts and bolts are tight. When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: • Start your engine, • Shift into a gear, and • Make sure the parking brake has released. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. Engine Cooling When Trailer Towing Your cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 5-25. 4-44
