Preparing to tow

Use the proper equipment for towing a trailer and make sure it is

properly attached to your vehicle. See your authorized dealer or a

reliable trailer dealer if you require assistance.

Hitches

ON PICK-UP TRUCKS, the trailer hitch provided on this vehicle

enhances collision protection for the fuel system. DO NOT

REMOVE!

Do not use hitches that clamp onto the vehicle’s bumper or attach to the

axle. You must distribute the load in your trailer so that 10%–15% for

conventional towing or 15%-25% fifth-wheel towing of the total weight of

the trailer is on the tongue.

Integrated hitch rating

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.
