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

uuWhen Driving uPrecautions While Driving
Driving
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.

uuWhen Driving uShifting
Driving
Use the paddle shifters to change betwee n 1st and 9th gears without removing your
hands from the steering wheel. The transmission will switch to the sequential mode.
■When the transmi ssion is in (D (D-paddle shift mode):
The vehicle will go into the sequential mode momentarily, and the gear selection
indicator becomes more prominent.
The sequential mode is automatically canc eled and the gear selection indicator
returns to ordinary display under the following conditions.
• Hold the
(+ paddle shifter for a few seconds.
• Once you start traveling at a constant speed.
• The vehicle comes to a complete stop.
• When you change to another Integrated Dynamics System mode.
The sequential mode automatically shifts under following condition
• Accelerator pedal depressed beyond the click.
• Engine speed reaches near the tachometer’s red zone.
• Engine speed reaches idle speed while deceleration.
■Sequential Mode1Sequential Mode
When sequential mode is selected, the gasoline
engine powers the vehicle.

Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering.1 Agile Handling Assist
The agile handling assist ca nnot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the front of the
car while the agile handling assi st is activated. This is
normal.

uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The an ti-lock brake system (ABS) helps you retain steering
control when brak ing very hard.
2Brake Assist System P. 367
2 Anti-lock Brake System (ABS) P. 366
■Brake squeal
To satisfy the performance under a wide range of driving conditions, a high-
performance braking system is equipped on your vehicle. You may hear the brake
squeal under certain conditions, such as vehicle speed, deceleration, humidity, and
so on. This is not a malfunction.
■Foot Brake1 Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to replaced. Have your
vehicle checked by an authorized Acura NSX dealer.
If you hear only an occasional squeak or squeal when
you initially apply the brake pe dal, this may be normal
and caused by high frequen cy vibration of the brake
pads against the rotating brake disc.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply regene rative braking by taking
your foot off the accelera tor pedal and downshifting
to a lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.
