Towing a Trailer
Safety Chains
Always use safety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let the
chains drag on the ground.
Sway Control
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
Trailer Mirrors
Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don't, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.

Spare Tires
When towing a trailer, we
recommend that you carry a full-size
spare wheel and tire for your vehicle
and trailer. See page 269 for proper
tire size, page 280 for how to store a
full size wheel and tire, and page
275 for information on changing a
flat tire.
Remember to unhitch the trailer
before changing a flat. Ask your
trailer sales or rental agency where
and how to store the trailer's spare
tire.
