This position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and have your f oot of f the
accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see on
page .
To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch. Press the brake
pedal to shift from Park to Reverse.
To shif t f rom Reverse to Neutral,
come to a complete stop and then
shif t.
Your vehicle has a reverse lockout so
you cannot accidentally shif t to
Reverse from Neutral or any other
driving position when the vehicle
speed exceeds 7 9 mph (12 14
km/h).
If you cannot shif t to Reverse when
the vehicle is stopped, press the
brake pedal and slowly shift to
Neutral, and then to Reverse.
If there is a problem in the reverse
lockout system, or your vehicle’s
battery is disconnected or goes dead,
you cannot shif t to Reverse. (Ref er
to Shif t Lock Release on page ). Use Neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from Neutral to
another gear.
Use this position f or
normal driving. The transmission
automatically selects a suitable gear
f or your speed and acceleration. You
may notice the transmission shif ting
up at higher speeds when the engine
is cold. This helps the engine warm
up f aster.

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly or
your vehicle may roll if it is on an
incline.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.Make sure the moonroof and the
windows are closed.
Turn of f the lights.
Place any packages, valuables, etc.
in the cargo area, or take them
with you.
Lock the doors.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.If the vehicle is f acing uphill, turn
the f ront wheels away f rom the
curb.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.

Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you.
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 taking your f oot of f the
accelerator and downshif ting to a
lower gear.Check the brakes after 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. Be extra
cautious in your driving.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Your vehicle 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.
Braking System DesignBrake Wear Indicators
Braking System

Front

The Anti-lock Brake System (ABS)
helps prevent the brakes f rom
locking up and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.
The ABS also balances the f ront-to-
rear braking distribution according
to vehicle loading.
Let the ABS work f or you by always
keeping f irm, steady pressure on the
brake pedal. This is sometimes
ref erred to as ‘‘stomp and steer.’’You will f eel a pulsation in the brake
pedal when the ABS activates, and
may hear some noise. This is normal:
it is the ABS rapidly pumping the
brakes. On dry pavement, you will
need to press on the brake pedal
very hard before the ABS activates.
However, you may f eel the ABS
activate immediately if you are trying
to stop on snow or ice.
If the ABS indicator comes on, the
anti-lock f unction of the braking
system has shut down. The brakes
still work like a conventional system,
but without anti-lock. You should
have the dealer inspect your vehicle
as soon as possible.
You should never pump the brake pedal.

If the ABS indicator and the break
system indicator come on together
and the parking break is f ully
released, the front-to-rear braking
distribution system may also shut
down.
Test your brakes as instructed on
page . If the brakes f eel normal,
drive slowly and have your vehicle
repaired by your Acura dealer as
soon as possible. Avoid sudden hard
braking which could cause the rear
wheels to lock up and possibly lead
to a loss of control.It only helps with the
steering control during braking.

corner too f ast or making a sudden
lane change. Always drive at a safe
speed f or the road and weather
conditions. on loose or
uneven surf aces, such as gravel or
snow, than a vehicle without anti-
lock.
Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road.

Important Saf ety Reminders
A BS does not reduce the time or
distance it takes to stop the
vehicle.
A BS will not prevent a skid that
results f rom changing direction
abruptly, A vehicle with A BS may require a
longer distance to stop
A BS cannot prevent a loss of
stability.

The Vehicle Stability Assist system
helps to stabilize the vehicle during
cornering if the vehicle turns more
or less than desired. It also assists
you in maintaining traction while
accelerating on loose or slippery
road surf aces. It does this by
regulating the engine’s output, and
by selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.When VSA activates, you will see the
VSA Activation indicator blink.
If the VSA system indicator comes
on while driving, pull to the side of
theroadwhenitissafe,andturnoff
the engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on, or comes
back on while driving, have the VSA
system inspected by an Acura dealer.

Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase Acura
equipment whenever possible.
Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed, maintained, and
also meets state regulations.
A weight distributing hitch is not
recommended f or use with your
MDX.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.
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.
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.
Electric brakes must be
electronically actuated. Do not
attempt to tap into your vehicle’s
hydraulic system. See your brake
manuf acturer f or more inf ormation
on installing electric brakes.
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.
We strongly recommend that you
have your Acura dealer install an
Acura hitch and use the required
f luid coolers. Using non-Acura
equipment may result in serious
damage to your vehicle. T owing Equipment and

Check trailer light requirements f or
the areas where you plan to tow.
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
Acura dealer install an Acura wiring
harness and converter. 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 Acura dealer.
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. Foryoursafetyandthesafetyof
others, take time to practice driving
maneuvers bef ore heading f or the
open road, and f ollow the guidelines
below.
Avoid towing a trailer during your
vehicle’s f irst 600 miles (1,000 km).

smaller arc and it can hit or run
over something the vehicle misses.
Allow more time and distance f or

When driving with a f ix-sided (e.g.
camper, utility) trailer, do not
exceed 55 mph (88 km/h). At
higher speeds, the trailer may
sway or affect vehicle handling.
Whenbeingpassedbyatruckor
large vehicle, cross-winds and air
turbulence can disrupt your
steering and cause your trailer to
sway. Keep a constant speed, steer
straight ahead, and do not try to
make quick steering or braking
corrections.
Do not park on an incline unless it
is unavoidable. If you must, turn
the vehicle’s wheels toward the
curb on a downhill or away f rom
the curb on an uphill. Af ter
parking, place wheel chocks at
each trailer tire on the downhill
side.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

If the vehicle’s wheels 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.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, reduce speed
and, if necessary, pull to the side of
the road and let the engine cool.
If the transmission shif ts f requently
while going up a hill, shif t down one
gear.
If youmuststopwhenfacinguphill,
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.
