2007 Buick LaCrosse Owner's Manual - Page 329

There are three important considerations have to do with weight: • The weight of the trailer • The weight of the trailer tongue • The total weight on the vehicle's tires Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers and cargo must be subtracted from the maximum trailer weight. Ask your dealer for our trailering information or advice, or you can write us at: Buick Customer Assistance Center P.O.

It should never weigh more than 1,000 lbs (450 kg). But even that can be too heavy. It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much the vehicle is used to pull a trailer are all important. It can also depend on any special equipment that is on the vehicle, and the amount of tongue weight the vehicle can carry. See "Weight of the Trailer Tongue" later in this section for more information. 329
