WARNING: Do not exceed the GVWR or the GAWR specified on the certification label. WARNING: Towing trailers beyond the maximum recommended gross trailer weight exceeds the limit of the vehicle and could result in engine damage, transmission damage, structural damage, loss of vehicle control, vehicle rollover and personal injury. Preparing to tow Use the proper equipment for towing a trailer and make sure it is properly attached to your vehicle. Contact your authorized dealer or a reliable trailer dealer as soon as possible if you require assistance. Hitches Do not use hitches that clamp onto the vehicle bumper; use a load carrying hitch. You must distribute the load in your trailer so that 10-15% of the total weight of the trailer is on the tongue. Weight-distributing hitch When hooking-up a trailer using a load-equalizing hitch, always use the following procedure: 1. Park the unloaded vehicle on a level surface. With the ignition on and all doors closed, allow the vehicle to stand for several minutes so that it can level. 2. Measure the height of a reference point on the front and rear bumpers at the center of the vehicle. 249 2010 Flex (471) Owners Guide, 2nd Printing USA (fus)
