NOTE:The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to “Tire Safety
Information” in “Starting and Operating” for further
information. The addition of passengers and cargo may
require reducing trailer tongue load and Gross Trailer
Weight (GTW). Redistributing cargo (to the trailer) may
be necessary to avoid exceeding Rear Gross Axle Weight
Rating (GAWR) of 3,700 lbs (1 678 kg).
Trailer Hitch Receiver Cover Removal (Summit
Models) — If Equipped
