Maintenance When Trailer Towing Your vehicle will need service more often when you're pulling a trailer. See Scheduled Maintenance on page 6-4 for more information. Things that are especially important in trailer operation are automatic transaxle fluid (don't overfill), engine oil, axle lubricant, 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're trailering, it's a good idea to review this information before you start your trip. Check periodically to see that all hitch nuts and bolts are tight. Engine Cooling When Trailer Towing Your cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 5-29. Changing a Tire When Trailer Towing If you get a flat tire while towing a trailer, be sure to secure the trailer and disconnect it from the vehicle before changing the tire. 4-46
