Hitches
Do not use a hitch that either clamps onto the bumper or attaches to the
axle.
Distribute the trailer load so 10-15% of the total trailer weight is on the
tongue.
Weight-Distributing Hitches
WARNING: Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of the
weight-distributing hitch, which may cause unpredictable handling, and
could result in serious personal injury.

Towing
When attaching the trailer wiring
connector to your vehicle, only use
a proper fitting connector that
works with the vehicle and trailer
functions. If your vehicle has a
trailer towing package, it may have
a 7–pin connector. Some connectors
may have the SAE J2863 logo,
which confirms that it is the proper
wiring connector and works
correctly with your vehicle.
