However, if electronic accessories
are improperly installed, or exceed
your vehicle’s electrical system
capacity, they can interf ere with theoperation of your vehicle, or even
cause the airbags to deploy.
Make sure the accessory does not
obscure any lights, or interf ere
with proper vehicle operation or
perf ormance.
Be sure electronic accessories do
not overload electrical circuits
(see page ).
If possible, have your dealer inspect
the f inal installation. Bef ore installing any accessory:
When properly installed, cellular
phones, alarms, two-way radios, and
low-powered audio systems should
not interf ere with your vehicle’s
computer-controlled systems, such
as the SRS and anti-lock brake
system.

These positions

select the D position, only the f irst
f our gears are selected. When you
select D , only the f irst three gears
are selected. D can also keep the
transmission f rom cycling between
f ourth and f if th gears in stop-and-go
driving, and D can keep the
transmission f rom cycling between
third and f ourth gears. This position locks
the transmission in second gear. It
does not downshif t to f irst gear
when you come to a stop. Second
gives you more power when climbing,
and increased engine braking when
going down steep hills. Use second
gear when starting out on a slippery
surf ace or in deep snow. It will help
reduce wheelspin.

When the brake pads need replacing,
you will hear a distinctive metallic
‘‘screeching’’ sound when you apply
the brakes. If you do not have the
brake pads replaced, they will begin
screeching all the time.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by downshif ting to a lower
gear and taking your f oot of f the
accelerator pedal.
Check your brakes af ter driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Since a
longer distance is needed to stop
with wet brakes, be extra cautious
and alert in your driving.
Your Acura is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.
Put your f oot on the brake pedal only
when you intend to brake. Resting
your f oot on the pedal keeps the
brakes applied lightly, causing them
to build up heat. Heat build-up can
reduce how well your brakes work. It
also keeps your brake lights on all
the time, conf using drivers behind
you.
All f our brakes have audible brake
wear indicators.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not conf use this with the
brake wear indicators. The
indicators make a very audible
‘‘screeching.’’ Brake Wear Indicators

Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed and maintained.
Since local requirements may vary,
check with appropriate state
authorities to be sure that your
equipment will meet all regulations
in the areas where you plan to tow. Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase Acura
equipment whenever possible. Your
dealer offers a trailer package that
includes a hitch, a ball mount, a
wiring harness, a transmission f luid
cooler and a heavy-duty power
steering f luid cooler.We strongly recommend that you
have your Acura dealer install a
genuine Acura hitch and the
required f luid coolers. Using non-
Acura equipment may result in
serious damage to your vehicle.
A weight distributing hitch is not
recommended f or use with your
MDX as an improperly adjusted
weight distributing hitch may reduce
handling stability and braking
perf ormance.
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
so they can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but to 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.
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 Acura dealer.

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).
Otherwise, 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 and installer. Follow
the manufacturer’s attachment
instructions caref ully.If you tow more than 8 hours in one
day, you should repeat the above
procedure at least every 8 hours.
(when you stop f or f uel, etc.)
Do the f ollowing to prepare your
MDX f or ‘‘f lat towing.’’ Perf orm this
procedure every day immediately
bef ore you begin towing, and f ollow
this procedure exactly; otherwise,
severe automatic transmission
damage will occur. Check the transmission f luid level
(see page ). Maintaining the correct f luid level
is very important.
Start the engine.
Leave the ignition switch in
ACCESSORY (I) so the steering
wheel does not lock. Make sure
the radio and any items plugged
into the accessory power sockets
are turned of f so you do not run

Towing Your Vehicle Behind a Motorhome

The route presents limits (some
roads are too steep and bumpy f or
example). You have limits (in driving
skills and comf ort). And your vehicle
also has limits (traction, stability, and
power, f or instance).
Driving of f -highway can be
hazardous if you f ail to recognize
limits and take proper precautions.
For example, you can have an
accident or rollover during
maneuvers such as turning, driving
on hills, or over large obstacles.
Utility vehicles have a signif icantly
higher rollover rate than other types
of vehicles. To avoid loss of control
or rollover, be sure to f ollow all
recommendations and precautions
on page and in this section.
Seat belts are just as important of f -
road as on paved roads. Wherever
you drive, make sure you and your
passengers always wear seat belts. If
children or inf ants are along f or the
ride, see that they are properly
secured. In a rollover crash, an
unbelted person is more likely to die
than a person wearing a seat belt. On many unpaved roads, you won’t
f ind lane markers, traf f ic signals, or
signs to warn you of possible trouble
ahead. It’s up to you to continually
assess the situation and drive within
limits.
Remember that your MDX has
higher ground clearance and a
higher center of gravity than
passenger vehicles designed f or use
only on pavement. This means your
vehicle can more easily tip or roll
over if you make abrupt turns or
drive on slopes.
Be sure to store cargo properly, and
do not exceed your MDX’s cargo
load limits (see pages and ).
