Notes: - For high altitude operation, reduce GCW by 2% per 1,000 ft.
(300 meters) elevation. For definitions of terms used in this table and
instructions on how to calculate your vehicle load, refer to Vehicle
loading in this chapter. Maximum trailer weights shown. The combined
weight of the completed towing vehicle and the loaded trailer must not
exceed the GCWR.
* -When towing maximum loads under high outside temperatures and
on steep grades, the A/C system may cycle on and off to protect the
engine from overheating. This may result in a temporary increase of
interior temperatures.
