transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.

For high altitude operation, reduce GCW by 2% per 1,000 ft.
(300 meters) elevation.
*When towing on roads with steep grades or moderate but long
sustained grades (5 miles [8 km] or more), or when ambient
temperatures exceed 100°F (37°C), vehicle speed should not exceed
45 mph (72 km/h) in both cases.
