2009 Acura RL Owner's Manual

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 f ront 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 f ollow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and maintained,
and that it meets f ederal, state,
province, and local regulations.
Any hitch used on your vehicle must
be properly bolted to the underbody.
Thebestwaytoconfirmthatall
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
manuf acturer) 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 f irst time you set up
a towing combination (a f ully loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.

Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let the
chains drag on the ground.If you choose electric brakes, be
sure they are electronically actuated.
Do not attempt to tap into your
vehicle’s hydraulic system. No
matter how successf ul it may seem,
any attempt to attach trailer brakes
to your vehicle’s hydraulic system
will lower braking ef f ectiveness and
create a potential hazard.

installing electric brakes.Trailer lights and equipment must
comply with f ederal, state/province,
and local regulations. Check with
your local trailer sales or rental
agencies f or the requirements in the
area where you plan to tow, and use
only equipment designed f or your
vehicle.
Since lighting and wiring vary by
trailer type and brand, you should
have a qualified technician install a
suitable connector between the
vehicle and the trailer. Improper
equipment or installation can cause
damage to your vehicle’s electrical
system and af f ect your vehicle
warranty.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.

Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.

Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Follow all normal precautions when
parking, including f irmly setting the
parking brake and putting the
transmission in Park. Also, place
wheel chocks at each of the trailer’s
tires.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
Always drive slowly and have
someone guide you when backing up.

emergency, see page .
If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in

as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed, and shif t down to S

the lower gear (3, 2 or 1) in the S

not ‘‘ride’’ the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer. 519
