Chevrolet TRACKER 2003 Manual page 205

After you've loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights
are proper. If they aren't, you may be able to get them
right simply by moving some items around in the
trailer.
Total Weight on Your Vehicle's Tires
Be sure your vehicle's tires are inflated to the upper limit
for cold tires. You'll find these numbers on the
tire-loading information label at the rear edge of the
driver's door or see Tires on page 5-59. Then be sure
you don't go over the GVW limit for your vehicle,
including the weight of the trailer tongue.
Hitches
It's important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why you'll need the right hitch. Here
are some rules to follow:
If you make holes in the body of your vehicle, be
sure to seal them when you remove the trailering
equipment. If you don't seal them, dirt, water,
and even deadly carbon monoxide (CO) from your
exhaust can get into your vehicle. See Engine
Exhaust on page 2-30.
Your vehicle is readily designed to accept a trailer hitch.
The frame rail ends already have holes and weld
nuts in place to accept the four bolts needed to attach
the hitch bar.
To help simplify setting up your trailer lights, there is a
trailer wiring connector located behind the left rear
trim panel. If needed, your dealer can provide help in
removing the trim panel and accessing this wiring
connector.
Your vehicle's trailer wiring has separate turn signal and
brake light circuits, which means you will most likely
need to purchase a converter to operate conventional
trailer lights.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the
tongue of the trailer to help prevent the tongue from
contacting 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. Never allow
safety chains to drag on the ground.
