Saturn 2007 Relay 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 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 391. Then be sure you 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:
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.
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 later
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 151. Dirt and water can, too.
