Trailer Recommendations You must subtract your hitch loads from the Cargo Weight Rating (CWR) for your vehicle. CWR is the maximum weight of the load your vehicle can carry. It doesn't include the weight of the people inside. But you can figure about 150 lbs. (68 kg) for each seat. The total cargo load must not be more than your vehicle's CWR. Weigh your vehicle with the trailer attached, so that you won't go over the GVWR or GAWR. If you are using a weight-distributing hitch, weigh the vehicle without the spring bars in place. You'll get the best performance if you spread out the weight of your load the right way, and if you choose the correct hitch and trailer brakes.

Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle. Notice: Pulling a trailer improperly can damage your vehicle and result in costly repairs not covered by your warranty. To pull a trailer correctly, follow the advice in this part, and see your dealer for important information about towing a trailer with your vehicle. 4-62
