Saturn 2009 VUE Hybrid - Manual (Page 215)

The weight at the rear axle could be
850 lbs (386 kg) X 1.5 = 1,275 lbs
(578 kg). Since the rear axle already
weighs 2,700 lbs (1 225 kg), adding
1,275 lbs (578 kg) brings the total to
3,975 lbs (1 803 kg). This is very
close to, but within the limit for
RGAWR as well. The vehicle is set to
trailer up to 8,500 lbs (3 856 kg).
If the vehicle has many options and
there is a front seat passenger
and two rear seat passengers with
some luggage and gear in the
vehicle as well, 300 lbs (136 kg)
could be added to the front
axle weight and 400 lbs (181 kg) to
the rear axle weight. The vehicle
now weighs:
Weight is still below 7,200 lbs
(3 266 kg) and you might think 700
additional pounds (318 kg) should
be subtracted from the trailering
capacity to stay within GCWR limits.
The maximum trailer would only be
7,800 lbs (3 538 kg). You may go
further and think the tongue weight
should be limited to less than
1,000 lbs (454 kg) to avoid
exceeding GVWR. But the effect on
the rear axle must still be considered.
Because the rear axle now weighs
3,100 lbs (1 406 kg), 900 lbs
(408 kg) can be put 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
only 600 lbs (272 kg) of tongue
weight that can be handled. Since
tongue weight is usually at least
10 percent of total loaded trailer
weight, expect that the largest trailer
the vehicle can properly handle is
6,000 lbs (2 721 kg).
It is important that the vehicle
does not exceed any of its
ratings — GCWR, GVWR, RGAWR,
Maximum Trailer Rating or Tongue
Weight. The only way to be sure it is
not exceeding any of these ratings is
to weigh the vehicle and trailer.
Total Weight on the Vehicle’s
Tires
Be sure the vehicle’s tires are
inflated to the upper limit for cold
tires. These numbers can be found
on the Certification label or see
Loading the Vehicle on page 4-18
for more information. Make sure not
to go over the GVW limit for the
vehicle, or the GAWR, 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
the right hitch is needed.
• The rear bumper on the 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.
