2. Potential Map Inaccuracy and Route Safety. Maps used by this system may be inaccurate because of changes in roads, traffic controls,
routing, or driving conditions. Always use good judgment and co mmon sense when following suggested routes. Do not follow the ro ute
suggestions if doing so would result in an unsafe or illegal driving maneuver, if you would be placed in an unsafe situation, or if you would
be directed into an area that you consider unsafe. Do not rely on any navigation featur es included in the system to route you to emergency
services. Not all emergency services such as police, fire stations, hospitals, or clinics are likely to be contained in the map database for such
navigation features. Ask local authorities or an emergency services operator for such locations and routes. The driver is ultimately
responsible for the safe operation of the vehicle and therefore, must evaluate whether it is safe to follow the suggested directions. Any
navigation features are pr ovided only as an aid. Make your driving decisions based on your obse rvations of local conditions and existing
traffic regulations. Navigation features are not a substitute for your personal judgment. Any route suggestions made by the SOF TWARE or
SERVICES should never replace any local traffic regulations or your personal judgment or knowledge of safe driving practices.
3. Speech Recognition:
You acknowledge and understand that HONDA and PROV IDERS may record, retain, and use voices commands
when you use the speech recognition componen ts of the SOFTWARE or SERVICES. You and all VEHICLE operators and passengers (a)
consent to the recording and retention of voice commands in support of providing speech recognition components and (b) release HONDA
and PROVIDERS from all claims, liabilities, and losses that may result from any use of such recorded voice commands. Recognitio n errors
are inherent in speech recognition. It is your responsibility to monitor any speech recognition functions included in the syste m and address
any errors. Neither HONDA nor PROVIDERS will be liable for any damages arising out of errors in the speech recognition process.
4. Distraction Hazards.
Navigation features may require manual (non-verbal) input or setup. Attempting to perform such set-up or insert
data while driving can seriously distract your attention and could cause a crash or other serious consequences; the ability to undertake such
interactions may also be limited by state or local law, which laws you are responsible to know and follow. Even occasional shor t scans of
the screen may be hazardous if your attention has been diverted away from your driving at a critical time. Pull over and stop the vehicle in
a safe and legal manner before attempting to access a function of the system requiring prolonged attention. Do not raise the vo lume
excessively. Keep the volume at a level where you can still hear outside traffic and emergency signals while driving. Driving while unable
to hear these sounds could result in a crash.

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. Ho wever, 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

Continued
Driving
Vehicle Stability Assist ® (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering 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.
■VSA ® Operation
1 Vehicle Stability Assist ® (VSA ®), aka Electronic Stability Control
(ESC), System
VSA ® may not function properly if tire type and size
are mixed. Make sure to use the same size and type
of tire, and the air pr essures as specified.
2 Tire and Wheel Replacement P. 411
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 entire 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 Stability Control (ESC). The
system also includes a traction control function.

This button is used to change VSA ® modes.
See below for more information.
VSA ® is turned on every time you turn the
power system on, even if you press the button
the last time you drove the vehicle.
■When the Integrated Dynamics System mode is in QUIET mode, SPORT
mode, or SPORT+ mode To enter Stuck Vehicle Assist mode, press
the VSA® OFF button until a single beep is
heard and the VSA ® OFF indicator illuminates.
u This message appears on the driver
information interface for a few seconds.
If the Integrated Dynamics System mode is
changed, VSA® will remain in Stuck Vehicle
Assist mode.
To exit Stuck Vehicle Assist mode, press the
VSA ® OFF button until a single beep is heard
and the VSA ® OFF indicator extinguishes.
■VSA ® On and Off1 Vehicle Stability Assist ® (VSA ®), aka Electronic Stability Control
(ESC), System
In Stuck Vehicle Assist mode, your vehicle will have
normal braking and corn ering ability, but VSA®
traction and stability enhancement becomes less
effective.
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with Stuck Vehicle Assist mode.
In Stuck Vehicle Assist mode, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the button
pressed if you are not able to free it without.
Immediately after freeing your vehicle, be sure to
press the button again. We do not recommend
driving your vehicle with Stuck Vehicle Assist mode.
You may hear a motor sound coming from the front
of the vehicle while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.

When the VSA ® system is off, the traction control
system and agile handling assist system are also off.
We do not recommend driving your vehicle with the
VSA ®, traction control syst em, and agile handling
assist system switched off.
If the low tire pressure/TPMS indicator comes on or
blinks, the VSA® system comes on automatically. In
this case, you can select Stuck Vehicle Assist mode
to free a stuck vehicle, but you cannot select the

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance a ccording to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on the tire sidewall
between tread shoulder an d maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested un der controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.
■Uniform Tire Quality Grading
■Treadwear

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.
