Maintenance When Trailer Towing Your vehicle will need service more often when you're pulling a trailer. See the Maintenance Schedule for more on this. Things that are especially important in trailer operation are automatic transaxle fluid (don't 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'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. Towing a Trailer (Except Models with 2.4L L4 Engine and 4-Speed Automatic Transaxle) Do not tow a trailer if your vehicle is: D a convertible model, D equipped with a 2.2L L4 (Code 4) engine or D equipped with a manual transaxle or a three-speed automatic transaxle. Engine Cooling When Trailer Towing Your cooling system may temporarily overheat during severe operating conditions. See "Engine Overheating" in the Index. 4-41
