Total Weight on Your Vehicle's Tires
Be sure your vehicle's tires are inflated to the
recommended pressure for cold tires. You'll find these
numbers on the Tire-Loading Information label (found
inside the trunk lid) or see "Loading Your Vehicle"
in the Index. 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:
0
a
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 "Carbon Monoxide" in the Index). Dirt
,and water can, too.
The bumpers on your vehicle are not intended for
hitches. Do not'attach rental hitches or other
bumper-type hitches to them. Use only a
frame-mounted hitch that does not attach to
the bumper.
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
Because you have anti-lock brakes, do not try to tap into
your vehicle's brake system. If you do, both brake
systems won't work well, or at all.
Driving with a Trailer
Towing a trailer requires a certaifi amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
