Cadillac 2007 SRX Automobile User Manual


 
Because your rear axle now weighs 3,100 lbs
(1 406 kg), you can only put 900 lbs (408 kg) on the
rear axle without exceeding RGAWR. The effect of
tongue weight is about
1.5 times the actual weight. Dividing the 900 lbs
(408 kg) by 1.5 leaves you with being able to
handle only 600 lbs (272 kg) of tongue weight.
Since tongue weight is usually at least 10 percent of
total loaded trailer weight, you can expect that the
largest trailer your vehicle can properly handle is
6,000 lbs (2 721 kg).
It is important that you make sure your vehicle
does not exceed any of its ratings — GCWR,
GVWR, RGAWR, Maximum Trailer Rating
or Tongue Weight. The only way to be sure you
are not exceeding any of these ratings is to weigh
your vehicle and 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. See Loading
Your Vehicle on page 322. 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 132. Dirt
and water can, too.
