tow Acura RDX 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 carefully observe
the load limits, use the proper
equipment, and follow the guidelines
in this section.
Be sure to read the sectiononpage
if you plan to tow of f paved
surf aces.
The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,500 lbs (680 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. Theweightthatthe
tongue of a f ully-loaded trailer puts
on the hitch should be approximately
10 % of the total trailer weight. Too
much tongue load reduces f ront-tire
traction and steering control. Too
little tongue load can make the
trailer unstable and cause it to sway.

Exceeding any load limit or

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

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 4,894 lbs
(2,220 kg).
The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo,
and the tongue load must not exceed
2,546 lbs (1,155 kg) on the f ront axle,
and 2,381 lbs (1,080 kg) on the rear
axle. The maximum
allowable weight of the f ully loaded
vehicle and trailer is 6,394 lbs (2,900
kg)
Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, how
much load you are towing, and
where you tow.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in this section. Also make
sure that all equipment is properly
installed and maintained, and that it
meets f ederal, state, province, and
local regulations. 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.
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.

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.
Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own 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.
Seeyourtrailerdealerorrental
agency f or more inf ormation on
installing electric brakes.
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.

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.

agency if any other items are
recommended or required f or your

Since lighting and wiring vary by
trailer type and brand, you should
have a qualif ied 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.
Your vehicle has a trailer lighting
connector located under the right
side tool case in the cargo area.

When climbing hills, closely watch
your temperature gauge (see pages
and ). If it nears the H (Hot)
mark, turn the A/C of f , reduce
speed and, if necessary, pull to the
side of the road to let the engine cool.
When driving down hills, reduce
your speed, and shif t down to S
position, or use the puddle shif t to
the lower gear (3, 2 or 1)in the S
position. When towing a trailer, do
not ‘‘ride’’ the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
Use the D position when towing a
trailer on level roads. See ‘‘
’’ in the next column f or
additional gear inf ormation. Do not
exceed 55 mph (88 km/h). At higher
speeds, the trailer may sway or
af f ect vehicle handling.
Make turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
canhitorrunoversomethingthe
vehicle misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.
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.

If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat.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.
Always drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; then turn the wheel to the lef t
to get the trailer to move to the lef t,
andturnthewheelrighttomovethe
trailer to the right.Follow all normal precautions when
parking, including putting the
transmission in Park and f irmly
setting the parking brake. Also, place
wheel chocks at each of the trailer’s
tires.

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
Inspect valve clearance
Replace engine coolant
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).

Check
the condition of the battery
monthlybylookingatthetest
indicator window. The label on the
battery explains the test indicato r’s
colors.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehic le’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.Battery
posts,
terminals, and related accessories
contain lead and lead compounds.
If
additional battery maintenance is
needed, see your dealer or a
qualified technician.
Check
the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
future corrosion.
If your vehicle’s battery is
disconnected, or goes dead, the time
setting will be reset to 1:00. To set
the time again, f ollow the setting
procedure (see page ). 198
