The available towing capacity may be less than the maximum towing capacity due to the passenger and cargo load in the vehicle. Remember to keep trailer tongue weight between 10 - 15% of the trailer weight or within the trailer tongue load specification recommended by the trailer manufacturer. If the tongue load becomes excessive, rearrange the cargo to obtain the proper tongue load. Do not exceed the maximum tongue weight specification shown in the "Towing load/specification" chart even if the calculated available tongue weight is greater than 15%. If the calculated tongue weight is less than 10%, reduce the total trailer weight to match the available tongue weight. Always verify that available capacities are within the required ratings. Trailer frontal area CAUTION Exceeding the maximum trailer frontal area specification may exceed the towing capacity of the vehicle. 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 ЉTowing 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. 9-20 Technical and consumer information
