uuWhen Driving uVehicle Stability AssistTM (VSA ®), aka Electronic Stability Control (ESC), System
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. 413
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.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, a nd 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.
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.

1Oil Check
For a proper oil level readi ng, the dipstick must be
inserted with the flat si de of the dipstick handle
facing the oil fill cap.
The amount of oil consum ed depends on how the
vehicle is driven and the cl imatic and road conditions
encountered. The rate of oil consumption can be up
to 1.05 US quart (1 liter) per 625 miles (1000 km).
Consumption is likely to be higher when the engine is
new.

Maintenance
Cooling System
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank. Add the engine coolant accordingly.
1. Make sure the engine and radiator are cool.
2. Open the hatch.
2 Opening the Hatch P. 387
3.Remove the left engine compartment
cover.
2 Engine Compartment Cover P. 389
4.Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
5. Inspect the cooling system for leaks.
Specified coolant: Acura Long Life Antifreeze/Coolant Type 2
■Checking the Coolant
1Cooling System
NOTICE
Genuine Acura engine cool ant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout -31°F (-35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult an authorized
Acura NSX dealer for details.
If Acura antifreeze/coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Ac ura coolant can result in
corrosion, causing the cooling system to malfunction
or fail. Have the cooling system flushed and refilled
with Acura antifreeze/cool ant as soon as possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. Th ey may not be compatible
with the coolant or with the engine components.
3WARNING
Removing the reserve tank cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the reserve tank
cap.
