Tires, Wheels and Loading • A final example for your vehicle with 1,400 lb. (635 kg) of cargo and luggage capacity. You and one of your friends decide to pick up cement from the local home improvement store to finish that patio you have been planning for the past 2 years. Measuring the inside of the vehicle with the rear seat folded down, you have room for 12-100 lb. (45 kg) bags of cement. Do you have enough load capacity to transport the cement to your home? If you and your friend each weigh 220 lb. (99 kg), the calculation would be: 1,400 - (2 x 220) (12 x 100) = 1,400 - 440 - 1,200 = - 240 lb. No, you do not have enough cargo capacity to carry that much weight. In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 540 = -103 kg. You will need to reduce the load weight by at least 240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then the load calculation would be: 1,400 - (2 x 220) - (9 x 100) = 1,400 - 440 - 900 = 60 lb. Now you have the load capacity to transport the cement and your friend home. In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x 45 kg) = 635 - 198 - 405 = 32 kg. The above calculations also assume that the loads are positioned in your vehicle in a manner that does not overload the Front or the Rear Gross Axle Weight Rating specified for your vehicle on the Safety Compliance Certification Label found on the edge of the driver's door. TRAILER TOWING Note: Long wheel based vehicles are NOT rated for towing. Your vehicle is classified as a light duty towing vehicle. Do not tow a trailer until your vehicle has been driven at least 1,000 miles (1,600 km). Towing a trailer places an additional load on your vehicle's engine, transmission, brakes, tires and suspension. Inspect these components carefully after towing. Your loaded trailer should weigh no more than 1,500 lb. (680 kg). Do not exceed the GVWR specified on the Safety Compliance 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. The GCW of your vehicle and trailer should not exceed 6,600 lb. (2,993 kg). 164 2009 Grand Marquis (grn) Owners Guide (own2002), 2nd Printing USA (fus)
