ABS Acura MDX 2003 Owner's Manua

Your vehicle is equipped with many
features that work together to
protect you and your passengers
during a crash.
These saf ety f eatures are designed
to reduce the severity of injuries in a
crash. However, you and your
passengers can’t take f ull advantage
of these saf ety f eatures unless you
remain sitting in a proper position
andIn f act, some saf ety
f eatures can contribute to injuries if
they are not used properly. Some saf ety f eatures do not require
anyactiononyourpart.These
include a strong steel f ramework
that forms a safety cage around the
passenger compartment; f ront and
rear crush zones that are designed to
crumple and absorb energy during a
crash; a collapsible steering column;
and seat belt tensioners that
automatically tighten the front seat
belts in the event of a crash.

Head restraints can help protect you
f rom whiplash and other injuries. For
maximum protection, the back of
your head should rest against the
center of the head restraint.
Reclining a seat-back too f ar reduces
the seat belt’s ef f ectiveness and
increases the chance that the seat’s
occupant will slide under the seat
belt in a crash and be seriously
injured. Move the f ront
seats as far back as possible, and
keep adjustable seat-backs in an
upright position whenever the
vehicle is moving.
Your vehicle’s seats are designed to
keep you in a comf ortable, upright
position so you can take f ull
advantage of the protection offered
by seat belts and the energy
absorbing materials in the seats.
How you adjust your seats and seat-
backs can also affect your safety. For
example, sitting too close to the
steering wheel or dashboard
increases the risk of you or your
passenger being injured by striking
theinsideof thevehicle,orbyan
inf lating airbag. Keeping your doors locked reduces
thechanceof beingthrownoutof
the vehicle during a crash. It also
helps prevent occupants f rom
accidentally opening a door and
f alling out, and outsiders f rom
unexpectedly opening your doors.

This indicator comes on f or a f ew
seconds when you turn the ignition
switch ON (II). It will then 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).
This light normally comes on f or a
f ew seconds when you turn the
ignition switch ON (II), and when
the ignition switch is turned to
START (III). If this light comes on at
any other time, there is a problem in
theABS.If thishappens,takethe
vehicle to your dealer to have it
checked. With the light on, your
vehicle still has normal braking
ability but no anti-lock. For complete

This light has two f unctions:
This indicator comes on when you
turn the ignition switch ON (II). It
is a reminder to check the parking
brake. A beeper sounds if you try
to drive with the parking brake not
f ully released. Driving with the
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
inf ormation, see page .

This section gives you tips on
starting the engine under various
conditions, and how to operate the
automatic transmission. It also
includes important inf ormation on
parking your vehicle, the braking
system, the VTM-4 System, the VSA
system, and f acts you need if you are
planning to tow a trailer.

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.

distance between vehicles under
those conditions.
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. such as trying to take a
corner too f ast or making a sudden
lane change. Always drive at a safe,
prudent speed f or the road and
weather conditions. it only helps with steering
control during braking. You should
always maintain a saf e f ollowing
distance f rom other vehicles.
The ABS is self -checking. If anything
goes wrong, the ABS indicator on
the instrument panel comes on (see
page ). This means the anti-lock
f unction of the braking system has
shut down. The brakes still work like
a conventional system without anti-
lock, providing normal stopping
ability. You should have the dealer
inspect your vehicle as soon as
possible.69

If the ABS indicator and the brake
system indicator come on together,
and the parking brake 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 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.377
