Driving
Vehicle Stability AssistTM (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 brake sy stem. You will also
see the indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (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. 417
When the VSA ® system indicator comes on and stays
on while driving, there may 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 Stab ility Control (ESC). The
system also includes a traction control function.

uuWhen Driving uSPORT HYBRID Super Handling All-Wheel-DriveTM (SPORT HYBRID SH-AWD ®)
Driving
SPORT HYBRID Super Handling All-Wheel-DriveTM
(SPORT HYBRID SH-AWD ®)
The system controls and transfers varying amounts of motor and/or engine torque
to each wheel in accordance with the driving conditions.
SPORT HYBRID SH-AWD ® helps to enhance driving stability, and lets you handle
situations like slippery surf aces better than when drivin g with standard two wheel
drive. However, the system does not help to enhance braking. Be cautious about the
following:
• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.
1SPORT HYBRID Super Handling All-Wheel-DriveTM (SPORT
HYBRID SH-AWD ®)
Do not drive through deep water.
The SPORT HYBRID SH-AWD ® system 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 pressures as specified. 2 Tire and Wheel Replacement P. 417

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d helps you retain steering control by
pumping the brakes rapidly, much faster than you can.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
You may hear an operating noise when the ABS is working. Depress the brake pedal
and keep holding the pedal firmly down. On dry pavement, you will need to press
on the brake pedal very hard before the ABS activates. However, you may feel the
ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have your
vehicle checked by an authorized Acura NSX dealer
immediately.
The ABS does not reduce the ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while vehicle is
accelerates.
These sounds are normal to ABS systems and are no
cause for concern.

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/cm
2)
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 tr ead. 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. 416
•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 tire inflation and
maintenance.

Maintenance
The tire identification number (TIN) is a group of numbers and letters that look like
the example in the side column. TIN is located on the sidewall of the tire.
Cold Tire Pressure – The tire air pressure when the vehicle has been parked for at
least three hours or driven less than 1 mile (1.6 km).
Load Rating – Means the maximum load that a ti re is rated to carry for a given
inflation pressure.
Maximum Inflation Pressure – The maximum tire air pressure that the tire can
hold.
Maximum Load Rating – Means the load rating for a tire at the maximum
permissible inflation pr essure for that tire.
Recommended Inflation Pressure – The cold tire inflation pressure recommended
by the manufacturer.
Treadwear Indicators (TWI) – Means the projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist
TM (VSA ®) system to work incorrectly.
It is best to replace all four tires at the same time.
If you replace a wheel, only use TPMS spec ified wheels approved for your vehicle.
Make sure that the wheel’s specificati ons match those of the original wheels.
