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.

uuWhen Driving uHigh Voltage Battery
Driving
High Voltage Battery
The High Voltage battery gradually discharges when the vehicle is not in use. As a
result, if your vehicle is parked for an ex tended period of time, the battery level may
get low. Keeping the High Voltage battery’s charge level low can shorten its life.
To maintain the High Voltage battery, driv e your vehicle for more than 30 minutes
to recharge it at least once every three months. Also, try to park in shaded areas
instead of direct sunlight.

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 .

• You are wearing the driver’s seat belt.
• The power system is on.
• The transmission is not in

•When the driver’s seat belt is unfastened while
your vehicle is stopped and brake hold is applied.
•When the power system is turned off while brake
hold is applied.
•When there is a problem with the Brake Hold

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.

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.

Do not park your vehicle near flammable objects,
such as dry grass, oil, or timber.
Heat from the exhaust can cause a fire.
3WARNING

A vehicle that rolls away could cause a crash
resulting in serious injury or death.
Always keep your foot on the brake pedal

NOTICE
The following can damage the drivelineY•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.
