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.

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

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

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.
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 braking.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. You will also see
the VSA Activation Indicator blink.

The VSA system indicator (see page) comes on and stays on when
there is a problem with the VSA
system. The VSA Activation
indicator will also come on. If the VSA indicator comes on while
driving, pull to the side of the road
when it is saf e and turn of f the
engine. Reset the system by
restarting the engine, and watch the
VSA system indicator. If the
indicator remains on, or comes back
on while driving, have the VSA
system inspected by your Acura
dealer.
If the indicator does not come on
when the ignition switch is turned
ON(II),theremaybeaproblem

dealer inspect your vehicle as soon
as possible.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and

This switch is under the lef t vent.

VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
Deactivate the VSA system if you
need to drive with the compact spare
tire installed (see page ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
car. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
