2007 GMC Envoy Owner's Manual - Page 353

This is called Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel, cargo, and trailer tongue weight, if pulling a trailer. The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle, or the GAWR for either the front or rear axle. And, if you do have a heavy load, you should spread it out. Similar appearing vehicles may have different GVWRs and capacity weights. Please note your vehicle's Certification/Tire label or consult your dealer for additional details. {CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle. Using heavier suspension components to get added durability might not change your vehicle's weight ratings. Ask your dealer to help you load your vehicle the right way. Notice: Overloading your vehicle may cause damage. Repairs would not be covered by your warranty. Do not overload your vehicle. 353
