uuBrakinguBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The an ti-lock brake system (ABS) helps you retain steering
control when brak ing very hard.

■ Brake squeal
To satisfy the performance under a wide range of driving conditions, a high-
performance braking system is equipped on your vehicle. You may hear the brake
squeal under certain conditions, such as vehicle speed, deceleration, humidity, and
so on. This is not a malfunction.
■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times. If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to replaced. Have your
vehicle checked by an authorized Acura NSX dealer.
If you hear only an occasion al squeak or squeal when
you initially apply the brake pedal, this may be normal
and caused by high frequen cy vibration of the brake
pads against the rotating brake disc.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply regene rative braking by taking
your foot off the accelera tor pedal and downshifting
to a lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.

Activating the automatic brake hold system
on steep hills or slippery roads may still
allow the vehicle to move if you remove
your foot from the brake pedal.
If a vehicle unexpectedly moves, it may
cause a crash resulting in serious injury or
death.
Never activate the automatic brake hold
system or rely on it to keep a vehicle from
moving when stopped on a steep hill or
slippery roads.
3WARNING
Using the automatic brake hold system to
park the vehicle may result in the vehicle
unexpectedly moving.
If a vehicle moves unexpectedly, it may
cause a crash, resulting in serious injury or
death.
Never leave the vehicle when braking is
temporarily kept by automatic brake hold
and always park the vehicle by putting the
transmission in

• You engage the parking brake.
Under the following conditions, the system automatically cancels, and the parking brake is applied: • Braking is kept for more than 10 minutes.
• The driver’s seat belt is unfastened.
• The power system is turned off.
• Brake Hold System Problem appears on the driver information interface.
■ Turning off the automa tic brake hold system

Whether the system is on, or the system is activated,
the automatic brake hold turns off once the power
system is off.
Make sure to turn off the automatic brake hold

uuBrakinguAnti-lock Brake System (ABS)
Driving
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 you.
The electronic brake distributi on (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution 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 pe dal. This is sometimes referred to as
“stomp and steer.” ■ ABS operation
You may hear an operating noise when the ABS is working. Depress the brake pedal
and keep holding the pedal firmly down. On dry pavement, you will need to press
on the brake pedal very hard before the AB S activates. However, you may feel the
ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have your
vehicle checked by an authorized Acura NSX dealer
immediately.
The ABS does not reduce the ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
• When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
• When tire chains are installed.
The following may be observed with the ABS system:
• Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the engine has been started and while vehicle is
accelerates.
These sounds are normal to ABS systems and are
no cause for concern.

Parking Your Vehicle
When Stopped 1.Depress the brake pedal firmly.
2. With the brake pedal depressed, pull up th e electric parking brake switch slowly,
but fully.
3. Change the gear position to
(P .
4. Turn off the power system.
uThe electric parking brake indicator goes off in about 15 seconds.
Always confirm the electric parking brake is se t, in particular if you are parked on an
incline.
During Auto Engine Stop, th e gear position changes to
(P and the engine restarts
automatically under the following conditions:
• You unfasten the driver side seat belt and open the door.
1Parking Your Vehicle
Do not park your vehicle near flammable objects,
such as dry grass, oil, or timber.
Heat from the exhaust can cause a fire.
3WARNING
The vehicle can roll aw ay if left unattended
without confirming that Park is engaged.
A vehicle that rolls away could cause a crash
resulting in seriou s injury or death.
Always keep your foot on the brake pedal
until you have confirmed that
(P is shown
on the gear position indicator.
1When Stopped
NOTICE
The following can damage the driveline: • Depressing the accelera tor and brake pedals
simultaneously.
• Changing to
(P before the vehicle stops completely.
When facing uphill, do not hold the vehicle by
depressing the accelerator pedal.
Doing so may cause the power system to overheat
and fail.
In extremely cold temperatures, the parking brake may
freeze up if applied. If such temperatures are expected, do
not apply the parking brake. If parking on a slope, either
turn the steering wheel so one of the front tires will contact
the curb or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the vehicle
may roll unexpectedly, leading to a crash.
