parking brake not f ully released
can damage the brakes and tires.
If the indicator remains lit after
you have f ully released the
parking brake while the engine is
running, or if it comes on while
driving, it can indicate a problem
in the brake system. For complete

need to be broken-in by moderate
use f or the f irst 200 miles (300
km). Your Acura is designed to operate on
premium unleaded gasoline with a
pump octane number of 91 or higher.
Use of a lower octane gasoline can
cause occasional, metallic knocking
noises in the engine and will result in
decreased engine perf ormance.
We recommend gasolines containing
detergent additives that help prevent
f uel system and engine deposits.
Using gasoline containing lead will
damage your vehicle’s emissions
controls. This contributes to air
pollution.
We also recommend that you do not
tow a trailer during the f irst 500

Any object
attached to or placed on the covers
marked ‘‘SRS AIRBAG,’’ in the
center of the steering wheel and
on top of the dashboard, could
interf ere with the proper operation
of the airbags. Or, if the airbags
inf late, the objects could be
propelled inside the vehicle and
hurt someone.
If a side airbag
inflates,acupholderorotherhard
object attached on or near the
door could be propelled inside the
vehicle and hurt someone.
Covering the outside edge of a
f ront seat-back, with a non-Acura
seat cover for example, could
prevent the airbag from inflating
properly.
Removing parts f rom your vehicle,
or replacing components with non-
Acura (aftermarket) components
could seriously af f ect your vehicle’s
handling, stability, and reliability.
Some examples are:
Lowering the vehicle with an
aftermarket suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to impact speed
bumps or other raised objects,
which could cause the airbags to
deploy.
Raising the vehicle with an
af termarket suspension kit can
af f ect the handling and stability.
Af termarket wheels, because they
are a universal design, can cause
excessive stress on suspension
components. Do not modif y your steering wheel
or any other part of your
Supplemental Restraint System.
Modif ications could make the
system inef f ective.
Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
If you plan to modif y your vehicle,
consult with your Acura dealer.

To engage the VTM-4 Lock:To disengage the VTM-4 Lock, do
one of the f ollowing:
Press the VTM-4 Lock button.
Move the shift lever to D , D or

Turn the ignition to OFF (0).
When you restart your MDX, the
VTM-4 Lock f eature will be of f .
The VTM-4 Lock will temporarily
disengage when the vehicle speed
exceeds 18 mph (30 km/h). It will
automatically engage again as the
speed slows below 18 mph (30
km/h). The light in the VTM-4 Lock
button will remain on the whole time.
The vehicle speed must be below
18 mph (30 km/h).
Move the shift lever to first (1),
second (2) or reverse (R) gear. To
shif t Reverse f rom Neutral, come
to a complete stop and then shift.
Press the VTM-4 Lock button.
The light in the button will come
on.
To get unstuck, apply light pressure
to the accelerator pedal. Do not spin
the f ront tires f or more than a f ew
seconds. Because of the amount of
torque applied to the rear tires, they
should not spin. This is normal. If
you are not able to get the vehicle to
move, apply the brakes to stop the
wheels, then reverse direction. 1.

Do not continuously spin the f ront tires
of your MDX. Continuously spinning
the f ront tires can cause transmission
or rear dif f erential damage.

Always use the parking brake when
you park your vehicle. The indicator
on the instrument panel shows that
the parking brake is not f ully
released; it does not indicate that the
parking brake is f irmly set. Make
sure the parking brake is set f irmly
or your vehicle may roll if it is
parked 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 making it
easier to move the shif t lever out of
Park when you want to drive away. 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 f ront 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.
Make sure the moonroof and the
windows are closed.
Never park over dry leaves, tall
grass, or other f lammable
materials. The three way catalytic
converter gets very hot, and could
cause these materials to catch on
fire. Lockthedoorswiththekeyorthe
remote transmitter. Place any packages, valuables, etc.,
in the cargo area or take them
with you. Turn of f the lights.

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

You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal; it is the ABS rapidly
pumping the brakes.this defeats the
purpose of the ABS. Let the ABS
work f or you by always keeping f irm,
steady pressure on the brake pedal
as you steer away from the hazard.
This is sometimes ref erred to as
Activation varies with the amount of
traction your tires have. On dry
pavement, you will need to press on
thebrakepedalveryhardbeforeyou
activate the ABS. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
Your vehicle has an Anti-lock Brake
System (ABS) as standard
equipment. ABS helps to prevent the
wheels f rom locking up and skidding
during hard braking, allowing you to
retain steering control.
When the f ront tires skid, you lose
steering control; the vehicle
continues straight ahead even
though you turn the steering wheel.
The ABS helps to prevent lock-up
and helps you retain steering control
by pumping the brakes rapidly; much
f aster than a person can do it.
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.
The ABS also balances the f ront-to
rear braking distribution according
to vehicle loading.
