Supplemental Restraint
System Indicator
This indicator comes on briefly when
you turn the ignition switch to the
ON (II) position. If it comes on at any
other time, it indicates a potential
problem with your front airbags. This
indicator will also alert you to a
potential problem with your airbag
system components. You will also
see a ‘‘CHECK AIRBAG SYSTEM ’’
message on the multi-information
display (see page 86). For more
information, see page 35.
U.S. Canada
Side Airbag Off
Indicator
This indicator comes on when you
turn the ignition switch to the ON
(II) position. If it comes on at any
other time, it indicates that the
passenger's side airbag has
automatically shut off. You will also
see a ‘‘PASSENGER SIDE AIRBAG
OFF ’’message on the multi-
information display (see page 86).
For more information, see page 35.
Anti-lock Brake System
(ABS) Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. If this indicator comes on at
any other time, there is a problem in
the ABS. If this happens, take the
vehicle to your dealer to have it
checked. With this indicator on, your
vehicle still has normal braking
ability but no anti-lock function. You
will also see a ‘‘CHECK ABS
SYSTEM ’’message on the multi-
information display (see page 87).
For more information, see page 455.

Braking System
Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The emergency
brake assist system increases the
stopping force when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you. Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Tire Pressure Monitoring System (TPMS), Braking System45410/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu

Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Brake Wear Indicators
All four brakes have audible brake
wear indicators.
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 for
the brakes to occasionally squeal or
squeak when you apply them.Anti-lock Brakes (ABS)
The anti-lock brake system (ABS)
helps prevent the wheels from
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the front-to-rear
braking distribution according to
vehicle loading.
You should never pump the brake pedal.Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as
‘‘stomp and steer. ’’You will feel 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 feel the ABS
activate immediately if you are trying
to stop on snow or ice.

ABS Indicator
If this indicator comes on, the anti-
lock function of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
You will also see a ‘‘CHECK ABS
SYSTEM ’’message on the multi-
information display (see page 87).
If the indicator comes on while
driving, test the brakes as instructed
on page 558. If the ABS indicator and the brake
system indicator come on together,
and the parking brake is fully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page 558. If the brakes feel normal,
drive slowly and have your vehicle
repaired by your 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.
Important Safety Reminders
ABS does not reduce the time or
distance it takes to stop the
vehicle.
It only helps with steering
control during braking.
ABS will not prevent a skid that
results from changing direction
abruptly, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions.
ABS cannot prevent a loss of
stability. 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.
A vehicle with ABS may require a
longer distance to stop on loose or
uneven surfaces, such as gravel or
snow, than a vehicle without anti-
lock.

In this case, your vehicle still has the
VSA traction and stability
enhancement, but it will not have the
trailer stability assist function.
If there is a problem with the VSA
system, the system and trailer
stability assist shuts off. The VSA
system indicator also come on (see
page 467).
The ABS indicator and the brake
system indicator may also come on
along with the VSA system indicator.
If you see these warning indicators,
have your vehicle checked at your
dealer as soon as possible.If you turn off the VSA, the trailer
stability assist function also shuts off.
Press and hold the VSA off switch
until you hear a beep (see page 468).
The VSA off indicator comes on as a
reminder. Press and hold the switch
again to turn the system on.
The function turns on every time you
start the engine along with the VSA,
even if you turned it off the last time
you drove the vehicle.
Off-Highway Driving Guidelines
General Information
Your vehicle has been designed
primarily for use on pavement. But
its higher ground clearance and
super handling-all wheel drive
(SH-AWD) system allow you to
occasionally travel on unpaved roads,
to campgrounds, picnic sites, and
similar locations. It is not designed
for trailblazing, mountain climbing,
or other challenging off-road
activities.
If you decide to drive on unpaved
roads, you will find that it requires
somewhat different driving skills.
Your vehicle will also handle
somewhat differently than it does on
pavement. Be sure to pay extra
attention to the precautions and tips
in this section, and get acquainted
with your vehicle before leaving the
pavement.Trailer Stability Assist, Off-Highway Driving Guidelines49410/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu

Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the installer perform a dynamic
balance.Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only Acura wheel weights for
balancing.Tire Rotation
To help increase tire life and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.
Replacing Tires and Wheels
Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire's sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a different
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
The ABS works by comparing the
speed of the wheels. When replacing
tires, use the same size originally
supplied with the vehicle. Tire size
and construction can affect wheel
speed and may cause the system to
activate.
When the tires are rotated, make
sure the air pressures are checked.
