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.

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 su rfaces better than when driving 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 safely 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. 411

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can ma nually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
power mode the vehicle is in.
Pull the electric parkin g brake switch up gently
and securely. u The parking brake indicator comes on.
■To release
The power mode must be in the ON position
to release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The parking brake indicator goes off.
Manually releasing the parking brake using
the switch helps your ve hicle start slowly and
smoothly when facing downhill on steep hills.
■Parking Brake1 Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parking brake.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 Jump Starting P. 446
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the electric servo brake
system until the vehicle comes to a stop. The
electric parking brake then applies, and the
switch should be released .

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution 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 th e 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 AB S activates. However, you may feel the
ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes under 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.

automatically under the following conditions:
• You unfasten the driver side seat belt and open the door.
1Parking Your Vehicle
Do not park your vehicle near flammable objects,
such as dry grass, oil, or timber.
Heat from the exhaust can cause a fire.
3WARNING
The vehicle can roll aw ay if left unattended
without confirming that Park is engaged.
A vehicle that rolls away could cause a crash
resulting in seriou s injury or death.
Always keep your foot on the brake pedal
until you have confirmed that
( P is shown
on the gear position indicator.
1 When Stopped
NOTICE
The following can damage the driveline:•Depressing the accelera tor and brake pedals
simultaneously.
•Changing to ( P before the vehicle stops completely.
When facing uphill, do not hold the vehicle by
depressing the accelerator pedal.
Doing so may cause the power system to overheat
and fail.
In extremely cold temperatures, the parking brake may
freeze up if applied. If such temperatures are expected, do
not apply the parking brake. If parking on a slope, either
turn the steering wheel so one of the front tires will contact
the curb or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the vehicle
may roll unexpectedly, leading to a crash.
