Acura 2008 RL - Manual (Page 386)

To achieve a proper tongue load,
start by loading 60 % of the load
toward the front of the trailer and
40 % toward the rear, then re-adjust
the load as needed.
The maximum allowable weight of
the vehicle, all occupants, all
accessories, all cargo, and the
tongue load is: 4,980 lbs (2,260 kg)
The maximum allowable weight of
the vehicle axles are: 2,680 lbs
(1,215 kg) on the front axle, and
2,380 lbs (1,080 kg) on the rear
axle.
Towing generally requires a variety
of supplemental equipment,
depending on the size of your trailer,
how much load you are towing, and
where you tow. To ensure the best
quality, we recommend that you
purchase Acura equipment
whenever possible.
Discuss your needs with your trailer
sales or rental agency, and follow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and maintained,
and that it meets federal, state,
province, and local regulations.
Any hitch used on your vehicle must
be properly bolted to the underbody.
The best way to confirm that all
loads are within limits is to check
them at a public scale. For public
scales in your area, check your local
phone book, or contact your trailer
dealer or rental agency for
assistance.
If you cannot get to a public scale,
you can estimate the total trailer
weight by adding the weight of your
trailer (as quoted by the
manufacturer) with everything in or
on the trailer.
If you normally pull the same load
each time you tow a trailer, you can
use a suitable scale or a special
tongue load gauge to check the
tongue load the first time you set up
a towing combination (a fully loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.
