Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can ma nually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
power mode the vehicle is in.
Pull the electric parkin g brake switch up gently
and securely. u The parking brake indicator comes on.
■To release
The power mode must be in the ON position
to release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The parking brake indicator goes off.
Manually releasing the parking brake using
the switch helps your ve hicle start slowly and
smoothly when facing downhill on steep hills.
■Parking Brake1 Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parking brake.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 Jump Starting P. 446
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four

uuBraking uAnti-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 distribu tion (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 pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
You may hear an operating noise when th e 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 depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes under 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.

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.

Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■Inflation guidelines
Properly inflated tires provide the best combination of handling, tread life, and
comfort. Refer to the driver’s doorjamb labe l or specifications page for the specified
pressure.
Underinflated tires wear unev enly, adversely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more prone to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month or before long trips, use a gauge to measure the pressure in all
tires. Even tires in good condition can lose 1 – 2 psi (10 – 20 kPa, 0.1 – 0.2 kgf/cm
2)
per month.
■Inspection guidelines
Every time you check inflation, also examine the tires and valve stems. Look for:
• Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,
splits, or cracks in the side of the tire . Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have an authorized Acura NSX dealer check the wheel
alignment.
• Excessive tread wear.
2 Wear Indicators P. 410
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4 – 6 psi (30 – 40 kPa, 0.3 – 0.4 kgf/cm
2) higher than
if checked when cold.
Have an authorized Acura NSX dealer check the tires
if you feel a consistent vi bration while driving. New
tires and any that have be en removed and reinstalled
should be properly balanced.
3WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding ti re inflation and
maintenance.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified
government test surfaces of asph alt and concrete. A tire marked
C may have poor traction performance.
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat and its
ability to dissipate heat when te sted under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperature can cause the material of the tire to degenerate and
reduce tire life, and ex cessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.
■Traction
■Temperature
1 Traction
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
1Temperature
Warning: The temperature grade for
this tire is establishe d for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.
