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.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a sma ll puncture, from a small nail for instance,
you can use the temporary tire repair kit so that you can drive to the nearest service
station for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface. Apply the parking
brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact an authorized Acura NSX dealer or a
roadside assistant to have the vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4 mm).•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.

Handling the Unexpected
Emergency Power System Off
The ENGINE START/STOP button may be used to turn the power system off due to
an emergency situation even while driving. If you must turn the power system off,
do either of the following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button three times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The gear position automatically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.
1 Emergency Power System Off
Do not press the ENGINE START/STOP button while
driving unless it is absolutely necessary for the power
system to be turned off.
If you press the ENGINE START/STOP button while
driving, the beeper sounds.
