Hitches
Do not use a hitch that clamps onto the vehicle's bumper; use a
load-carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
WARNING: The trailer hitch on this vehicle is part of the vehicle
rear crash safety structure. Do not remove the trailer hitch.
Failure to follow this warning could compromise vehicle crash structure
and increase the risk of injury in a rear end collision.
Integrated Hitch Rating
WARNING: Towing trailers beyond the maximum tongue weight
exceeds the limit of the towing system and could result in vehicle
structural damage, loss of vehicle control and personal injury.
The standard integrated hitch has two ratings depending on mode of
operation:
• Weight-carrying requires a draw bar and hitch ball. The draw bar
supports all the vertical tongue load of the trailer.
• Weight-distributing requires an aftermarket weight-distributing
system which includes draw bar, hitch ball, spring bars and snap-up
brackets. The vertical tongue load of the trailer is distributed between
the truck and the trailer by this system.

Note: These are hitch ratings only; actual vehicle ratings are dependent
on engine, transmission and axle combinations.
