uuWhen Driving uTire Pressure Monitoring System (TPMS)
Driving
To select the tire pressure monitor, set the
power mode to ON, and roll the right selector
wheel until you see the tire pressure screen.
The pressure for each tire is displayed in psi.
Tire Pressures Low is displayed when a tire
has significantly low pressure. The specific tire
is displayed on the screen.
Tire Pressure Too Low For High Speed
Driving is displayed when driving at an
extremely high speed and one or more tires
are underinflated.
u Decelerate and drive your vehicle until
the message disappears.
■Tire Pressure Monitor1Tire Pressure Monitor
The pressure displayed on the driver information
interface can be slightly different from the actual
pressure as measured by a gauge. If there is a
significant di fference between the two values, or if
the low tire pressure/TPMS indicator and the message
on the driver information in terface do not go off after
you have inflated the tire to the specified pressure,
have the system checked by an authorized Acura NSX
dealer.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumination of th e TPMS low tire pressure telltale.
Your vehicle has also been equi pped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the syst em detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illumina ted. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manu ally 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 parking brake switch up gently
and securely. u The electric 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 electric parking brake indicator goes
off.
Manually releasing the parking brake using
the switch helps your vehicle 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 If the 12-Volt Battery Is Dead P. 452
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 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.

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.
