Vehicle Stability Assist® (VSA®)
Also known as Electronic Stability Control (ESC), VSA helps stabilize the vehicle during cornering
if the vehicle turns more or less than what was intended. It assists in maintaining traction on
slippery surfaces by regulating engine output and selectively applying the brakes.
n
Turning VSA On or Off
VSA is turned on

every time you turn on the vehicle, even if you previously turned it off. If
you turn VSA off, your vehicle has normal braking and cornering ability, but not VSA traction
and stability enhancement.
To turn VSA on or off, press and hold the VSA OFF button
until you hear a beep. The VSA OFF indicator appears when
the system is off.
Turning VSA off also turns off traction control. That may make

DRIVINGDRIVING
High-Performance Driving
Your Acura NSX is designed, built and equipped with systems and features to provide you with
exceptional driving performance, 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 (including, for instance, use of Launch Control) that may create
heightened risks for yourself and any other road users who may be present (even if you are
unaware of them).
The NSX warranty does not cover any damage or failure resulting from high-performance
driving, competitive driving of any sort whatsoever, or use on a track or similar-type venue. See
warranty book for details.
NOTICE
NSX Track Mode (see page 136), Launch Control (see page 137) and other systems are
designed for increased performance, both in terms of acceleration 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 v

ehicle maintenance
•
Less than ideal road conditions and/or unfamiliarity with
the driving environment
•
Other traffic or road users
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 levels would otherwise allow you to do so. If you intend to engage in high-
performance driving, Acura strongly recommends that:
•
You first obtain appr
opriate, professional training
•
Wear the appropriate
driving clothing and gear (e.g., helmet, gloves and driving shoes)
•
Be fully rested and alert (fr
ee of drugs or alcohol)
•
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 vehicle. Because of these high loads, if your NSX is not in top condition or if certain
components, such as the brakes or tires, have undue wear, those components could experience
a loss of performance, or fail, when subjected to the additional loads. 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 adjustments made) before you engage in any high-performance driving.
In addition to any required maintenance, there are certain NSX specific items and protocols that
you should pay special attention to before, during and after engaging in any high-performance

152 || 153
DRIVINGDRIVING
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.
n
BEFORE DRIVING
•
With the vehicle park

ed on level ground, properly bleed brake system after replacing with
new Honda DOT 4 brake fluid or equivalent.
•
Inspect brake pad thickness and replace if 6.0mm

or less.
•
Burnish the brake pads so that

they have the performance characteristics necessary
to repeatedly and quickly slow the NSX when it is being operated at significantly 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.) A high performance burnish at the driving venue
prior to the first session of the day is highly recommended.
•
Inspect ALL cooling openings to confirm

they are open and free of debris such as leaves,
etc. Cooling openings include engine undercover ducts, heat resistance ducts, brake ducts,
radiators, and intercoolers.
•
Remove

Tire Repair Kit from the trunk, along with any other cargo area contents.
•
Check tire wear and

tire pressure, and make 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 Only tires and Ultra High Performance tires if temperatures will
be lower than 45°F (7°C).
•
If you anticipate sustained driving at speeds gr

eater 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 failure.
If driving at high speeds (over 168mph/270km/h),
adjust cold tire pressure as show n below to avoid
ex cess heat buildup and sudden tire failur e.

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 failure, loss of
control, and serious injury or death to you or others.
Do not install slick tires on the NSX.
WARNING
• Inspect all exhaust mounts for cracks or signs of
wear.
•
Inspect tailpipe active exhaust val
ves to ensure they are functioning correctly. You can
do this by cycling the IDS switch between SPORT and TRACK modes, while the engine is
idling.

n While Driving
•
You may see a brake warning message in
the Driver
Information Interface (and warning message chime) and/
or experience increased brake pedal stroke. If either occurs,
immediately slow down 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 critical to allow your vehicle to properly cool down.
Do not immediately stop your vehicle. Instead, continue driving at reduced speeds,
allowing for increased braking distances 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 oil temperature reaches the H mark during high-performance driving, have
your NSX inspected by an authorized Acura NSX dealer.
n
AFTER DRIVING
Check your NSX, and each of its r

elevant components, to make sure that it still is in a safe
operating condition (example: wheel lug bolt torque, tire pressure, etc.). We recommend
you repeat the Before Driving protocol. If any item shows excessive wear or appears to be
in an unusual condition, have it replaced, or exercise appropriate caution when driving and
see your authorized Acura NSX dealer
For more information, please contact your authorized Acura NSX dealer, and/or Acura Client
Relations (see page 213).
Cold or Rainy Weather Driving
Summer-only and Ultra High Performance (UHP) tires are very sensitive to ambient
temperatures and are designed to be used at temperatures above 45°F (7°C). Below that
temperature, Summer-only and UHP tires provide decreasing amounts of grip and other
performance attributes. At temperatures below -4°F (-20°C), the tire treads may become
brittle, resulting in permanent damage to the tread. A damaged tire may fail during use.
Therefore, if you will operate the vehicle when temperatures are below 45°F (7°C), we
recommend you install other tires (e.g., mud+snow, winter) designed to perform under the
expected conditions.
Use of Summer-only or Ultra High Performance tires at temperatures below 45°F
(7°C) may lead to a loss of performance and control, which could result in a crash,
serious injury or death.
WARNING
Your NSX is equipped with ultra-high-performance summer-only tires that, due to their
decreased tread depth, are at greater risk of hydroplaning on wet roads compared to regular
tires. Exercise caution when driving on wet surfaces.

Keyless Access Remote Battery Strength
If the battery life in your keyless access remote is weak, a
message appears in the driver information interface with
information on how to start the engine.
Touch the back of the keyless access remote to the ENGINE
START/STOP button while the indicator is flashing.
With the brake pedal pressed, press the ENGINE START/STOP
button within 10 seconds.
Emergency Power System Off
The ENGINE START/STOP button may be used to turn off the power system due to an
emergency situation even while driving. If you must turn off the power system, choose one of
the following operations:
Press and hold the ENGINE START/STOP button for two seconds,
OR
Firmly press the ENGINE START/STOP button three times.
Turning off the engine disables the power assist to the steering and braking systems. Thus,
it will require significantly more physical effort and time to steer and slow the vehicle.
Downshift gears and use both feet on the brake pedal, if necessary, to slow the vehicle and stop
immediately in a safe place.
Once the vehicle comes to a complete stop, the gear position automatically changes to (P) and
the power mode changes to VEHICLE OFF.
Do not press the button while driving unless it is absolutely necessary for the engine to be
switched off.
