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 Certification/Tire label. See Loading Your Vehicle
on page 4-45. 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:
• 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 don’t seal them,
deadly carbon monoxide (CO) from your exhaust
can get into your vehicle. See Engine Exhaust
on page 2-33. 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
If you tow more than 1,000 lbs (450 kg), use trailer
brakes. Because your vehicle has 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.
Be sure to read and follow the instructions for the trailer
brakes so you’ll be able to install, adjust and maintain
them properly.
