9-42 Driving and Operating Changing a Tire When Trailer Towing If the vehicle gets a flat tire while towing a trailer, be sure to secure the trailer and disconnect it from the vehicle before changing the tire. Maintenance When Trailer Towing The vehicle needs service more often when pulling a trailer. See Maintenance Schedule on page 11‑3 for more information. Things that are especially important in trailer operation are automatic transmission fluid, engine oil, belts, cooling system and brake system. It is a good idea to inspect these before and during the trip. Check periodically to see that all hitch nuts and bolts are tight. WARNING (Continued) Ask your dealer for advice and information about towing a trailer with the vehicle. Notice: Pulling a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To pull a trailer correctly, follow the advice in this section and see your dealer for important information about towing a trailer with the vehicle. The vehicle can tow a trailer if it is equipped with the proper trailer towing equipment. To identify the trailering capacity of the vehicle, read the information in "Weight of the Trailer" that appears later in this section. Trailering is different than just driving the vehicle by itself. Trailering means changes in handling, acceleration, braking, durability and fuel economy. Trailer Towing { WARNING The driver can lose control when pulling a trailer if the correct equipment is not used or the vehicle is not driven properly. For example, if the trailer is too heavy, the brakes may not work well - or even at all. The driver and passengers could be seriously injured. The vehicle may also be damaged; the resulting repairs would not be covered by the vehicle warranty. Pull a trailer only if all the steps in this section have been followed. (Continued) Engine Cooling When Trailer Towing The cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 10‑15.
