Total Weight on Your Vehicle's Tires
Be sure your vehicle's tires are inflated to the upper
limit for cold tires. You will find these numbers on
the Tire-Loading Information label at the rear edge
of the driver's door or see Loading Your Vehicle on
page 288. Then be sure you do not go over the
GVW limit for your vehicle, including the weight of
the trailer tongue.
Hitches
It is 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:
•
The rear bumper on your vehicle is not
intended for hitches. Do not attach rental
hitches or other bumper-type hitches to it. Use
only a frame-mounted hitch that does not attach
to the bumper.
•
Will you have to make any holes in the body of
your vehicle when you install a trailer hitch? If
you do, then be sure to seal the holes later
when you remove the hitch. If you do not seal
them, deadly carbon monoxide (CO) from your
exhaust can get into your vehicle. See Engine
Exhaust on page 140. Dirt and water can, too.

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
Does your trailer have its own brakes?
Be sure to read and follow the instructions for the
trailer brakes so you will be able to install,
adjust and maintain them properly. And because
you may have anti-lock brakes, do not try to
tap into your vehicle's brake system. If you do,
both systems will not work well, or at all.
