This may affect the towing performance and lead to vehicle damage. The trailer frontal area affects the towing load of a trailer. The frontal area is the total area of the vehicle and trailer that is affected by air resistance while towing. Do not exceed the maximum trailer frontal area specification shown in the Towing Load/Specification" chart. The frontal area can be determined by multiplying the width of the trailer by the height of the trailer. For example, a trailer that is 8 feet wide by 6 feet tall has a trailer frontal area of 48 square feet. In this case, the available towing capacity is 152 lb. (69 kg) less than the maximum towing capacity due to the passenger and cargo load in the vehicle. 9-28 Technical and consumer information
