2000 Saab 9-5 Owner's Manual - Page 152

152 Starting and driving WARNING Towing a trailer Trailer hitch attachment Trailer hitch attachments are available as accessories. These are designed for a maximum trailer weight of 2000 lbs. (900 kg). Use only the electrical trailer hitch socket provided in the spare wheel area in the luggage compartment for connecting the trailer electrics. Trailer weight Maximum recommended trailer weights for different gradients, with a view to comfort and drivability for manual and automatic cars, are shown on 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-licence provisions (see also page 227). Always undo the expansion tank filler cap carefully, releasing the pressure and any vapor before removing the cap completely. 3 As soon as possible, have the cooling system checked by an authorized Saab dealer. NOTE Use only a genuine Saab trailer hitch, since other models can damage the car's bodywork and electrical system (or in Canada, a high quality hitch designed to fit the car, available from a trailer hitch specialist). Consult an authorized Saab dealer for guidance on how to connect the trailer hitch electrical system. 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 that the journey starts at the hill and therefore apply only to short periods.
