Steps for determining the 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 1,400 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 lb.). In metric units (635–340 (5 x 68) = 295 kg.)
5. Determine the combined weight of luggage and cargo being loaded on
the vehicle. That weight may not safely exceed the available cargo and
luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle.
The following gives you a few examples on how to calculate the available
amount of cargo and luggage load capacity:
•Another example for your vehicle with 1,400 lb. (635 kg) of cargo and
luggage capacity. You decide to go golfing. Is there enough load
capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1,400 -
(5 x 220) - (5 x 30) = 1,400 - 1,100 - 150 = 150 lb. Yes, you have
enough load capacity in your vehicle to transport four friends and
your golf bags. In metric units, the calculation would be: 635 kg - (5 x
99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.
•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
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Note:Long wheel based vehicles are NOT rated for towing.
Follow these guidelines to ensure safe towing:
•Do not tow a trailer until your vehicle has been driven at least
1,000 miles (1,600 km).
•Consult your local motor vehicle laws for towing a trailer.
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•Stay within your vehicle’s load limits.
•Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
•Service your vehicle more frequently if you tow a trailer. Refer to
Special operating conditionsin your scheduled maintenance.
Your loaded trailer should weigh no more than 1,500 lb (680 kg). The
GCW of your vehicle and trailer should not exceed 6,600 lb (2,993 kg).
For load specification terms found on the label and instructions on
calculating your vehicle’s load, refer toVehicle loading - with and
without a trailerin this chapter. Remember to figure in the tongue load
of your loaded vehicle when figuring the total weight.
