from entering the passenger compart-

Tire pressures

tire pressure indicated on the Tire and
Loading Information label.
.

and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers’ specifications.
Safety chains
Always use a suitable chain between your
vehicle and the trailer. The safety chains
should be crossed and should be attached
to the hitch, not to the vehicle bumper or
axle. The safety chains can be attached to
the bumper if the hitch ball is mounted to
the bumper. Be sure to leave enough slack
in the chains to permit turning corners.
