Buick 2010 Lucerne - Manual (Page 288)

The Tire and Loading Information label also lists
the tire size of the original equipment tires (C) and
the recommended cold tire inflation pressures (D).
For more information on tires and inflation, see
Tires on page 6‑57 and Inflation - Tire Pressure on
page 6‑65.
There is also important loading information on
the Certification label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and
rear axle, see “Certification Label” later in this
section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle's placard.
2. Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be five 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400 − 750 (5 x 150) = 650 lbs).
