9-56 Driving and Operating The vehicle can tow a trailer when equipped with the proper trailer towing equipment. For trailering capacity, see Trailer Towing on page 9‑60. Trailering changes handling, acceleration, braking, durability and fuel economy. With the added weight, the engine, transmission, wheel assemblies and tires are forced to work harder and under greater loads. The trailer also adds wind resistance, increasing the pulling requirements. For safe trailering, correctly use the proper trailering equipment. The following information has important trailering tips and rules for your safety and that of your passengers. Read this section carefully before pulling a trailer. Driving Characteristics and Towing Tips Pulling a Trailer Here are some important points: . { 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. Ask your dealer for advice and information about towing a trailer with the vehicle. There are many laws, including speed limit restrictions that apply to trailering. Check for legal requirements. Do not tow a trailer at all during the first 1 600 km (1,000 mi) the new vehicle is driven. The engine, axle or other parts could be damaged. During the first 800 km (500 mi) that a trailer is towed, do not drive over 80 km/h (50 mph) and do not make starts at full throttle. This reduces wear on the vehicle. The vehicle can tow in D (Drive). Use a lower gear if the transmission shifts too often. . . .
