2004 Acura MDX ABS

This indicator has two f unctions:This indicator comes on when you
turn the ignition switch to ON (II).
It is a reminder to check the
parking brake. A beeper sounds if
you try to drive with the parking
brake not fully released. Driving
with the parking brake not fully
released can damage the brakes
and tires. This indicator normally comes on f or
a f ew seconds when you turn the
ignition switch to ON (II), and when
the ignition switch is turned to
START (III). If it comes on at any
other time, there is a problem in the
ABS. If this happens, have your
vehicle checked by your Acura
dealer. With this indicator on, your
vehicle still has normal braking
ability but no anti-lock. For more
inf ormation, see page .
This indicator comes on f or a f ew
seconds when you turn the ignition
switch to ON (II). It will go of f if you
have inserted a properly-coded
ignition key. If it is not a properly-
coded key, the indicator will blink
and the engine will not start (see
page ).
This indicator also blinks several
times when you turn the ignition
switch f rom ON (II) to ACCESSORY
(I) or LOCK (0).
If it remains on af ter you f ully
release the parking brake while
the engine is running, or if it
comes on while driving, there
could be a problem with the brake
system. For more inf ormation, see
page .

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.

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.
such as trying to take a
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.

they have no plastic or metal
reinf orcement along the back
edge, remove the metal
reinf orcement strips f rom the old
wiper blade, and install them in
the slots along the edge of the new
blade.Slide the new wiper blade into the
holder until the tabs lock.

REINFORCEMENT

It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.
If you ever replace a wheel, make
sure that the wheel’s specif ications
match those of the original wheels.Tires: Wheel:
See page f or DOT tire quality
grading inf ormation, and pagef or tire size explanation.
Replacement wheels are available at
your Acura dealer.
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 side wall).
TheABSworksbycomparingthe
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
work. Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a dif f erent
size or construction can cause the
ABS to work inconsistently.

Installing improper tires on your
