Total Weight On Your Vehicle's Tires; Trailer Brakes - Buick 2004 Rendezvous Owner's Manual

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
Certification/Tire Label at the rear edge of the driver's
door, or see Loading Your Vehicle on page 4-36. 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 will need the right hitch. Here
are some rules to follow:
•
If you will be pulling a trailer that, when loaded, will
weigh more than 2,000 lbs. (900 kg), use a properly
mounted, weight-carrying hitch and sway control
of the proper size. This equipment is very important
for proper vehicle loading and good handling
while driving.
•
Will you have to make any holes in the body of
your vehicle when you install a trailer hitch?
If you do, remember to seal the holes 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 2-30. 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 to help prevent the tongue from
contacting 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. Never allow
safety chains to drag on the ground.

Trailer Brakes

If your trailer weighs more than 1,000 lbs. (450 kg)
loaded, then it needs its own brakes – and they must be
adequate. Be sure to read and follow the instructions
for the trailer brakes so you'll be able to install,
adjust and maintain them properly.
Because your vehicle may have anti-lock brakes, do not
try to tap into your vehicle's brake system. If you do,
both brake systems will not work well, or at all.
