tow Acura RL 2007 User Guide

Your vehicle has been designed
primarily to carry passengers and
their cargo. You can also use it to
tow a trailer if you caref ully observe
the load limits, use the proper
equipment, and f ollow the guidelines
in this section.The weight that
the tongue of a f ully-loaded trailer
puts on the hitch should be
approximately 10 percent of the
trailer weight. Too much tongue
load reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable
and cause it to sway.
The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,000 lbs (450 kg).
Towing a load that is too heavy
can seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain.

Exceeding any load limit or

and trailer can cause a crash in
which you can be seriously hurt
or killed.

vehicle and trailer carefully

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.Thebestwaytoconfirmthatvehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, 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.
The maximum allowable weight of
the vehicle, all occupants, 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.

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.Acura recommends that any trailer
having a total weight of 1,000 lbs
(450 kg) or more be equipped with
its own electric or surge-type brakes.
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.Trailer lights and equipment must
comply with federal, state, and local
regulations. Check with your local
trailerdealerorrentalagencyforthe
requirements in your area, 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.

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.

The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques.

When driving uphill and downhill,
use the Sequential SportShif t mode
to provide the proper engine power
and engine braking on each gear.
Select f ourth, third, second, or f irst
gear; depending on the vehicle
speeds and road condition. Do not

trailer to jackknif e or turn over.
Drive slower than normal in all

Use D position when towing a trailer
on level roads. D is the proper shif t

Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause 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 firmly setting the
parking brake and putting the
tran smission in Park. Also, place
wheel chocks at each of the trailer’s
tires.
When
driving down hills, reduce
your speed, and shift down to second
gear. Do not ‘‘ride’’ the brakes, and
remember, it will take longer to slow
downandstopwhentowingatrailer. If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat.
When
climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning off, reduce speed and, if
necessary, pull to the side of the
ro ad to let the engine cool.
If the automatic transmission shifts
frequently while going up a hill, shift
to D .
Always drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; turn the wheel to the left to
get the trailer to move to the left,

Maintenance Sub Items
Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000 km), then every 15,000 miles (24,000 km).
Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive in dusty conditions, replace every 15,000
miles (24,000 km).
Replace dust and pollen filter If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and
from diesel-powered vehicles, replace every 15,000
miles (24,000 km).
Inspect drive belt
Replace transmission and transfer fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher
transmission and transfer temperatures.
This requires transmission and transfer fluid changes
more frequently than recommended by the
Maintenance Minder. If you regularly drive your
vehicle under these conditions, have the transmission
and transfer fluid changed at 60,000 miles
(100,000 km), then every 30,000 miles (48,000 km).
Replace spark plugs
Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), or in very low temperatures (under20°F, 29°C), replace every 60,000 mile (U.S.)/
100,000 km (Canada)

If you f requently tow a trailer. In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).
The timing belt should be replaced
at the intervals shown on the
maintenance minder. Replace the
belt at 60,000 miles (100,000 km) if
you regularly drive your vehicle in
one or more of these conditions:
Pour the f luid slowly and caref ully so
you do not spill any. Clean up any
spill immediately; it could damage
components in the engine
compartment.
Always use Honda Power Steering
Fluid. You may use another power
steering f luid as an emergency
replacement, but have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently, and have
the system inspected as soon as
possible.
