Oldsmobile 2002 Silhouette - Manual (Page 298)

4-37
If you’re using a weight - carrying or a
weight - distributing hitch, the trailer tongue weight (A)
should be 10 percent to 15 percent of the total loaded
trailer weight (B). Do not exceed the maximum
allowable tongue weight for your vehicle.
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights are
proper. If they aren’t, you may be able to get them right
simply by moving some items around in the trailer.
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 at the rear edge of the driver’s
door, or see “Tire Loading” 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:
D 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.
D If you’ll be pulling a trailer that, when loaded, will
weigh more than 2,000 lbs. (900kg). be sure to 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 when you’re driving.
D 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.
