To accurately check your loads at
the public scale, the vehicle and
trailer should be f ully loaded, and all
occupants should stay in the vehicle
while the attendant watches the
scale.Remember, maximum gross
combined weight should be
decreased 2 % f or every 1,000 f eet
(305 meters) of elevation.
Check the weight of the hitched
trailer. Write this number down.
Check the f ront gross axle weight.
Limit: 2882 lbs (1307 kg)
If you cannot weight on the rear
axle directly, you can calculate the
rear gross axle weight by
subtracting the weight in Step 1
from the weight in Step 2. Check the gross vehicle weight.

Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase Acura
equipment whenever possible.
Your dealer of f ers a trailer package
that includes a hitch, a ball mount, a
wiring harness, a heavy-duty
transmission f luid cooler.
Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed, maintained, and
also meets state, f ederal, province,
and local regulations.We strongly recommend that you
have your dealer install an Acura
hitch and use the required f luid
coolers. Using non-Acura equipment
may result in serious damage to your
vehicle.
To help prevent overheating, a
heavy-duty transmission f luid cooler
and a heavy-duty power steering
f luid cooler are required f or trailer
towing. These coolers are available
only f rom your dealer.
A weight distributing hitch is not
recommended f or use with your
vehicle, as an improperly adjusted
weight distributing hitch may reduce
handling, stability, and braking
perf ormance.
Check the weight of the unhitched
trailer. Limit: See page .
Calculate the tongue load.
Subtract the weight in Step 5 f rom

Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
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.
If you choose electric brakes, be
sure they are electrically 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.
See your brake manuf acturer f or
more inf ormation on installing
electric brakes.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.
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
Many states and provinces require
special exterior 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.When towing a trailer, we
recommend that you carry a f ull-size
spare wheel and tire for your vehicle
and trailer. See page f or proper
tire size, page f or how to store a
full size wheel and tire, and page
f or inf ormation on changing a
flat tire.
Remember to unhitch the trailer
bef ore changing a f lat. Ask your
trailer sales or rental agency where
and how to store the trailer’s spare
tire. 255

Trailer lights and equipment must
comply with f ederal, state, province,
and local regulations. Check trailer
light requirements f or the areas
where you plan to tow, and use only
equipment designed f or your vehicle.
To get to your vehicle’s trailer
lighting connector, open the tailgate,
remove the cargo cover, then
remove the rear panel trim. The
connector is on the lef t side.We recommend that you have your
dealer install a Acura wiring harness
and converter. This harness has
been designed f or your vehicle.
If you use a non-Acura trailer
lighting harness and converter, you
cangetthematingconnectorand
pins that mate with the connector in
your vehicle f rom your dealer.
When preparing to tow, and bef ore
driving away, be sure to check the
f ollowing:
The vehicle has been properly
serviced, and the tires, brakes,
suspension, cooling system, and
lights are in good operating
condition. If you tow f requently,
f ollow the Severe Conditions
maintenance schedule.
The trailer has been properly
serviced and is in good condition.
All weights and loads are within
limits.
Thehitch,safetychains,andany
other attachments are secure.
Allitemsonandinthetrailerare
properly secured and cannot shif t
while you drive.
Since lighting and wiring vary with
trailer type and brand, you should
also have a qualif ied mechanic install
a suitable connector between the
vehicleandthetrailer.

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.
If the transmission shif ts f requently
while going up a hill, shif t to D3.
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,
this could cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shif t down to D . Do
not ‘‘ride’’ the brakes.Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause trailer
swaying. 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 bottom of the steering
wheel, then turn the wheel to the lef t
to get the trailer to move to the lef t.
Turn the wheel to the right to move
the 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 the vehicle’s tires slip when
retrieving a boat f rom the water,
shif t to f irst gear, and turn on VTM-4
Lock (see page ). Disengage
VTM-4 Lock as soon as the boat is
out of the water to prevent damage
to the VTM-4 system.

Your MDX can be towed behind a
motorhome at legal highway speeds
up to 65 mph (100 km/h). Do not
exceed 65 mph (100 km/h) or severe
transmission damage will occur. To
avoid damage to the 4WD system, it
must be towed with all f our wheels
on the ground (f lat towing).
When purchasing a tow bar, make
sure you select a reputable
manuf acturer. Follow the
manufacturer’s attachment
instructions caref ully.
Perf orm this procedure every day
immediately bef ore you begin towing.
Otherwise, severe automatic
transmission damage will occur.Start the engine. Check the transmission f luid level
(see page ). Press on the brake pedal. Shif t the
lever through all the positions (P,

The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in the ACCESSORY (I)
position, and make sure the steering
wheel turns f reely bef ore you begin
towing.

The banks are sloped so you can
drive out.
The water is not f lowing too f ast.
Deep rushing water can sweep you
downstream. Even very shallow
rushingwatercanwashthe
ground f rom under your tires and
cause you to lose traction and
possibly roll over.
The banks and surf ace under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
If you decide it is saf e to drive
through water, choose a suitable
speed and engage the VTM-4 Lock.
Proceed without shif ting or changing
speeds, and do not stop the vehicle
or shut of f the engine.
After driving through water, test
your brakes. If they got wet, gently
pump them while driving slowly until
they operate normally. If the water is deeper than the wheel
hubs, some additional service may
be required. This service is not
covered by your warranties.
If you get stuck, engage the VTM-4
Lock (see page ). Caref ully try to
go in the direction (f orward or
reverse) that you think will get you
unstuck. Do not spin the tires at high
speeds. It will not help you get out
and may cause damage to the
transmission or VTM-4 system.
If you are unable to f ree yourself ,
your vehicle is equipped with f ront
and rear tow hooks designed f or this
purpose.
Use a nylon strap to attach the MDX
to the recovery vehicle and caref ully
take out the slack in the strap. Once
the strap is tight, the recovery
vehicle should apply f orce.
Remember that the recovery vehicleneeds good traction to avoid
becoming stuck, too.
You should never use a jack to try to
get unstuck. Your vehicle could
easily slip of f the jack and hurt you
or someone else.
You may be able to safely tow a
lightweight trailer (such as a
motorcycle or small tent trailer) of f -
road if you f ollow these guidelines.
Do not exceed 1,000 lbs (450 kg)
