A 4-pin gray connector is available as
an option at your dealer. This
connector has all of the circuits
required to install most electric
trailer brake controllers. A jumper
harness to adapt your electric trailer
brake controller to the vehicle is
included with the optional Genuine
Acura trailer hitch kit. To obtain a
connector and a trailer hitch kit, see
your dealer.
Have a qualif ied mechanic install
your trailer brake controller
f ollowing the trailer brake controller
manuf acturer’s instructions. Failure
to properly install the trailer brake
controller may increase the distance
it takes f or you to stop your vehicle
when towing a trailer.
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 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.
Seeyourtrailermanufacturerfor
more inf ormation on installing
electric brakes.
We strongly recommend that you
have your dealer install a class 3
hitch. Using non-Acura equipment
may result in serious damage to your
vehicle.
Read the trailer manufacturer’s
instructions, and select the
appropriate draw bar f or the height
of the trailer you will be towing.
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.

When towing a trailer, we
recommend that you carry a full-size
spare wheel and tire for your vehicle
and trailer. See page for 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.
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. 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. 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.

terminal in the trailer brake
controller connector.

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. 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.
Since lighting and wiring vary with
trailer type and brand, you should
also have a qualif ied mechanic install
a suitable connector between the
vehicle and the trailer.
Your vehicle is equipped with a
connector to install an optional trailer
lighting connector that mates with
your vehicle. You can get this
optional connector f rom your dealer. Ref er to the above illustration f or
wiring information.
We recommend that you have your
dealer install an Acura wiring
harness and converter. This harness
has been designed f or your vehicle.

Your vehicle tires and spare are in
good condition and properly
inflated.
When
preparing to tow, and before
driving away, be sure to check the
following: The trailer tires and spare are in
good condition and inflated as
recommended by the trailer
maker.
The
vehicle has been properly
serviced, and the brakes,
suspension, cooling system, and
lights are in good operating
condition.
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 shift

added weight, length, and
height of a trailer will affect your
vehicl e’s handling and performance,
so driving with a trailer requires
some special driving skills and
techniques.

If the autom atic transmission fluid
temperature increases and exceeds
the speci fied limit, the A/T
temperature indicator comes on (see
page ). You will also see a ‘‘A/T
TEMP HIGH’’ message on the multi-
information display.
Make turnsmoreslowlyandwider
than normal. The trailer tracks a
smaller arc than your vehicle, and it

vehicle misses.
Allow more time and distance for
braking. Do not brake or turn
suddenly as this could cause the
trailer to jackknife or turn over.
When
driving uphill and downhill,
use the Sequential SportShift mode
to provide the proper engine power
and engine braking on each gear.
Select fourth, third, second, or first
gear; dep ending on the vehicle
speeds and road condition. Do not
use fifth gear. The recommended
speed range for each gear position is
showninthetable.

lever position to use when towing a
trailer in hilly terrain. (See ‘‘ ’’onthenextpagefor
additional gear information.)
When towing a f ixed-sided trailer (e.
g., camper), do not exceed 55 mph
(88 km/h). At higher speeds, the
trailer may sway or affect vehicle
handling. 68

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 transmission shifts frequently
while going up a hill, shift to D3.
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 driving down hills, reduce
your speed and shift down to D . Do
not ‘‘ride’’ the brakes. Al
ways drive slowly and have
someone guide you when backing up.
Grip the of the steering wheel,
then turn the wheel to the left to get
the trailer to move to the left. Turn
the wheel to the right to move the
trailer to the right.
Follow all norm al precau tions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer’s
tires. If
the vehicles tires slip when
retr ieving a boat from the water,
keep D position and do not use the
sequential sport shif t mode. This
prevents the transmission damage.
Your vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page .
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.

Under these conditions, trailer
stability assist begins to stabilize the
vehicl e/trailer combination by
reducing the vehicle speed. The
control unit sends signals to
selectively apply the brakes and
regulate the engine output. The
brake lights of your vehicle will be
turned on automatically by the
system even if you do not keep the
pressu re on the brake pedal.
Your
vehicle is equipped with trailer
stability assist function. This
function works on the same sensors
as the vehicle stability assist (VSA)
system. This function helps to
stabilize the vehicl e/trailer
combination when the trailer
severely sways or oscillates. For
more information of the VSA system,
see page .
When the brakes are applied, the
trailer’s brake lights come on along
wi th the vehicle brake lights.
When the trailer stability assist
activates, you will see the VSA
activation indicator blink. There may
also be some noise from the VSA
hydraulic system. Trailer
stability assist cannot prevent
a loss of control. Always reduce the
ve hicle speed and steer firmly. Do
not brake suddenly or make quick
steering motion. It could cause the
trailertojackknifeorturnoverand
the system becomes ineffective.
Trailer stability assist cannot prevent
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. It helps only to
stabilize the vehicl e/trailer
combination in these conditions,
after the oscillation becomes severe.
If
the function detects the vehicle/
trailer instability, it checks if the
swaying is caused by the trailer, and
if the trailer swaying or oscillation is
increasing.
The vehicle/trailer combination is
more affected by crosswinds,
buffeting, and improper tongue load.
These conditions can make the
trailer unstable, and cause it to sway. Always obey the recommended
speed limits f or towing a trailer, see
page . Trailer stability assist will also be
inef f ective while driving at high
speed or towing a trailer with a high
center or gravity.

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 the water is deeper than the wheel
hubs, some additional service may
be required. This service is not
covered by your warranties.
If you decide it is saf e to drive
through water, choose a suitable
speed, and proceed without shif ting,
changing speeds, stopping, or
shutting of f the engine. If you get stuck, caref ully try to go in
the direction (f orward or reverse)
that you think will get you unstuck.
Donotspinthetiresathighspeeds.
It will not help you get out and may
cause damage to the transmission or
SH-AWD system.
After driving through water, test
your brakes. If they got wet, gently
‘‘pump’’ them while driving slowly
until they operate normally. If you are still 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 vehicle
needs good traction to avoidbecoming 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)
or a tongue weight of 100 lbs (45
kg).
Stay on smooth, level dirt roads,
and avoid driving in hilly terrain.
Allow extra room f or starting,
stopping, and turning.
Slow down if you encounter bumps
or other obstacles.
