High-Performance Driving
Your Acura NSX is designed, built and equipped with systems and features to
provide you with exceptional driving performa nce, including the ability to engage in
high-performance driving. However, due to the risks to both you and other road
users, including the risk of injury or death from a high-speed loss of control or crash,
if you engage in high-performance driving, Acura recommends you only do so
where conditions are controlled, such as at a track or other closed-course venue.
When driving on public roads you should always obey the posted speed limits and
other traffic laws, reduce speed as needed for traffic and environmental conditions,
and not engage in driving behaviors (includi ng, for instance, use of Launch Control)
that may create heightened risks for your self and any other road users who may be
present (even if you are unaware of them).
NSX TRACK mode, Launch Control and other systems are designed for increased
performance, both in terms of accelerati on and handling, up to near-performance-
limit conditions. They are most appropriately used on closed courses and they should
not be used on public roads. Use of these systems may delay the intervention of
vehicle safety systems designed to minimize the risk of a loss of traction or steering
control, and can cause the NSX to handle differently than you might expect or
would experience under normal driving conditions. Use of these systems will not
make up for a lack of appropriate driver experience and skill, and will not allow the
driver to overcome risks created by:
• A lack of proper vehicle maintenance
• Less than ideal road conditions and/or unfamiliarity with the driving environment
• Other traffic or road users

uuBefore Driving uHigh-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 le vels would otherwise allow you to do so.
If you intend to engage in high-perform ance 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 comp onents, such as the brakes or tires, have
undue wear, those components could experience a loss of performance, or fail,
when engaging in high-performance driv ing. Therefore, Acura highly recommends
that you undertake more proactive and fre quent 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-performance 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

uuBefore Driving uHigh-Performance Driving
Driving
• Burnish the brake pads shortly before high-performance driving so that they have
the performance characteristics necessary to repeatedly and quickly slow the NSX
when it is being operated at signific antly high speeds. (While the NSX’s brake
pads are properly burnished for the demands expected in ordinary day-to-day
driving, high-performance driving puts unique demands on the brake system
which require further burnishing.)
• Inspect ALL cooling openings to confirm th ey are open and free of debris such as
leaves, etc. Cooling openings include engi ne undercover ducts, heat resistance
ducts, brake ducts, radi ators, and intercoolers
• Remove Tire Repair Kit from the trunk, along with any other cargo area contents
• Check tire wear and tire pressure, and m ake certain wheel lug bolts are properly
torqued, as driving at high speed puts additional strain on tires and wheels. Never
use slick tires, and do not use Summer On ly tires and Ultra High Performance tires
if temperatures will be lower than 45°F (7°C)
• If you anticipate sustained driving at speeds greater than 168 mph/270 km/h,
adjust the cold tire pressure as shown on the driver door jamb warning label. This
will help avoid heat build-up and sudden tire failure1 High-Performance Driving
3WARNING
Use of slick tires/racing slicks may subject
the chassis and body components to higher
dynamic loads than they were designed for.
Higher than intended dynamic loads could
result in component fail ure, loss of control,
and serious injury or death to you or others.
Do not install slick tires on the NSX.

Driving
• Inspect all exhaust mounts for cracks or signs of wear
• Inspect tailpipe active exhaus t valves to ensure they are functioning correctly. You
can do this by cycling the Integrated Dynamics System mode switch between
SPORT and TRACK modes, while the engine is idling
WHILE DRIVING
• You may see a brake warning message in the Driver Information Interface (and
warning message chime) and/or expe rience increased brake pedal stroke.
If either occurs, immediately slow do wn and allow for increased stopping
distances. The message will disappear once the brakes have cooled and the
system has returned to normal operating condition
• After high-performance driving, it is critic al to allow your vehicle to properly cool
down. Do not immediately stop your vehicle. Instead, continue driving at reduced
speeds, allowing for increased braking di stances until your vehicle returns to
normal operating temperatures. Once you stop and safely park the NSX, open the
hatch to aid cooling. If the engine oi l temperature reaches the mark during
high-performance driving, have your NSX inspected by an authorized Acura NSX
dealer

Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the power
system or driveline, or caus e electrical component failure.
The vehicle is equipped with ultra high pe rformance summer tires that, due to their
decreased tread depth, are at greater risk of hydroplaning on wet roads compared
to regular tires. Exercise caut ion when driving on wet surfaces.
The vehicle is equipped with ultra high performance summer tires. These tires are
designed for optimum performance and handling in warm climates, and are not
suitable for below freezing, snowy or ic y weather conditions. If you drive under
these circumstances, use of winter tire s is recommended and may be mandatory,
depending on your region, province or territory.
2 Winter Tires P. 419
2 Cold Weather Driving P. 420
Due to limitations of the Lithium-ion Hi gh Voltage battery, the minimum starting
temperature for the vehicle is -4°F (-20°C).
Inability to start the vehicle and/or decrease d performance is expected if the vehicle
is operated at temperatures below -4°F (-20°C).
■In Rain
■In Snow and Ice
1 Precautions While Driving
NOTICE
Do not select a shift button while pressing the
accelerator pedal.
NOTICE
The following can damage the under spoiler, under
covers, front bumper, rear diffuser, brake cooling
components, and side sill:
•Parking the vehicle by a parking block•Parallel pa rking along the road shoulder•Driving toward the bottom of a hill•Driving up or down to a different surface level
(such as a road shoulder)
•Driving on a rutted or bumpy road•Driving on a road with potholes•Driving over speed bump
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the power mode is set to ACCESSORY while
driving, the power system will shut down and all
steering and brake power a ssist functions will stop,
making it difficult to control the vehicle.
Driving in snow or icy c onditions may accumulate ice
on the brake disk surface, reducing br aking power.
