uuBefore DrivinguHigh-Performance Driving
Driving
High-performance driving requires special skills, knowledge and experience, as the
safety risks are greatly increased when the NSX is operated at its upper performance
abilities. As a responsible NSX driver, you should not drive above your skill limits or
training, even if the NSX’s performance leve ls would otherwise allow you to do so.
If you intend to engage in high-performa nce driving, Acura strongly recommends
that: • You first obtain appropriate, professional training
• Turn off any devices or systems that may distract you from the driving task
High-performance driving in general, and the use of TRACK mode and Launch
Control in particular, puts very high loads on the NSX and its components, and
results in greater wear and tear on the vehicl e. Because of these high loads, if your
NSX is not in top condition or if certain com ponents, such as the brakes or tires, have
undue wear, those components could experience a loss of performance, or fail,
when engaging in high-performance drivin g. Therefore, Acura highly recommends
that you undertake more proactive and frequent maintenance than that required
under normal use and have your vehicle inspected at an authorized Acura NSX
dealer (and all necessary repairs or adju stments made) before you engage in any
high-performance driving. In addition to any required maintenance, there are
certain NSX specific items and protocols th at you should pay special attention to
before, during and after engaging in any high-performance driving. Ultimately, the
decision whether to engage in high-perfo rmance driving is yours, and depending on
your NSX’s condition and prior usage, the items and protocols listed below may or
may not be sufficient to ensure a safe driving experience.
BEFORE DRIVING •With the vehicle parked on level gro und, properly bleed brake system after
replacing with Acura Heavy Duty Brake Fluid DOT 4 or equivalent
• Inspect brake pad thickness an d replace if 6.0 mm or less

Driving
Vehicle Stability Assist TM
(VSA ®), aka Electronic
Stability Control (ESC), System VSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine and motor output and selectively applying the brakes.
When VSA® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic system . You will also see
the indicator blink.

When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Acura NSX dealer immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the en tire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stab ility Control (ESC). The
system also includes a traction control function.

Maintenance
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/cm2
)
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. 412
• 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.

Exterior Care
Dust off the vehicle body after you drive. Regularly inspect your vehicle for scratches
on painted surfaces. A scratch on a painted surface can result in body rust. If you
find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions: • If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
Do not use an automated car wash. • Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. St anding too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
