Safety Chains

You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer's recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack so you can turn with your rig.
And, never allow safety chains to drag on the ground.

Trailer Brakes

-
Because you have anti lock brakes, don't try to tap into
your vehicle's hydraulic brake system. If you do, both
brake systems won't work well, or at all. If you tow
more than 1,000 lbs. (450 kg), use trailer brakes. Be sure
to follow the instructions that come with the trailer or
from the brake manufacturer.
Be sure to read and follow the instructions for the trailer
brakes so you'll be able to maintain them properly.

Trailer Wiring Harness

If your vehicle is equipped with the 3,000
trailer towing package option, your vehicle comes with a
pouch containing a trailer towing jumper harness and a
trailer stub.
To attach the jumper harness, remove the trunk trim near
the left rear wheel well and connect it to the main body
harness connector which is taped down. The trailer stub
will attach to the trailer and connect to the jumper harness.

These trailer wiring harness color codes should be
followed when connecting it to your trailer:

Driving with a Trailer

Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
