Starting and driving Trailer weight Maximum recommended trailer weights for different gradients, for best comfort and driveability for manual and automatic cars, are shown in the drawing. Make sure you are familiar with the law regarding speed limits for towing, maximum trailer weights, trailer-braking requirements, and also any special driving-license provisions (see also page 222). 157 Recommendations for cars with automatic transmission The following time limits are based on the capacity of the cooling system in warm weather, i.e. approximately 86°F (30°C). Gradient Maximum of hill, % trailer weight, lbs. (kg) 10-15 1890 (850) Maximum duration, minutes IB1270 15 max. WARNING When towing a trailer, do not attempt to negotiate a hill having a gradient in excess of 15%. The weight distribution over the front wheels of the car will be insufficient to prevent wheelspin, making further progress impossible. In addition, the parking brake may not always be able to hold the car and trailer securely, with the result that the wheels can start to slide downhill. The specified trailer weights and gradients assume you are operating in hilly terrain and therefore apply only to short trips. The following time limits are based on the capacity of the cooling system in warm weather, i.e. approximately 104°F (40°C). Gradient Maximum of hill, % trailer weight, lbs. (kg) 10-15 1110 (500) Maximum duration, minutes NOTE Saab 9-3 Viggen cannot be equipped with a trailer hitch because of the design of the body and chassis. 15 max. When negotiating long hills, bear the following important considerations in mind: Do not drive continuously with the WINTER mode selected in hilly country when you are towing a trailer, as this will increase fuel consumption and risk overheating the transmission.
