Driving

Tire Pressure Monitoring System (TPMS) - Required 
Federal Explanation

Each tire, including the spare (if provided), should be checked 
monthly when cold and inflated to the inflation pressure 
recommended by the vehicle manufacturer on the vehicle placard 
or tire inflation pressure label.

(If your vehicle has tires of a different size than the size indicated 
on the vehicle placard or tire inflation pressure label, you should 
determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with 
a tire pressure monitoring system (TPMS) that illuminates a low 
tire pressure telltale 

when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you 
should stop and check your tires as soon as possible, and inflate 
them to the proper pressure.

Driving on a significantly under-inflated tire causes the tire to 
overheat and can lead to tire failure. Under-inflation also reduces 
fuel efficiency and tire tread life, and may affect the vehicle’s 
handling and stopping ability.

Tire 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 under-inflation has not reached the 
level to trigger illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped 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 system detects a malfunction, the 
telltale will flash for approximately one minute and then remain 
continuously illuminated. 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.

High 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 extended 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, drive 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. You can 
manually apply and release, or automatically release it.

■

Manual operations

Use the electric parking brake switch to apply or release the brake. Manually 
releasing the parking brake using the switch helps your vehicle start slowly and 
smoothly when facing down hill on steep hills.

■

To apply manually

Pull the electric parking brake switch up gently 
and securely.

u

The electric parking brake indicator 
comes on.

■

To release manually

1. Depress the brake pedal.
2. Press the electric parking brake switch.

You cannot apply or release the parking brake if the 
battery goes dead.

2 Jump Starting P. 434

If you pull and hold the electric parking brake switch 
while driving, the brakes on all four wheels are 
applied (by the VSA system) until the vehicle comes to 
a stop (at which point the electric parking brake is 
applied) or the switch is released.

Brake 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 anti-lock brake system (ABS) helps you retain steering 
control when braking very hard.

■

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 Brake

1

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 metallic 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 pedal, this may be normal 
and caused by high frequency 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 regenerative braking by taking 
your foot off the accelerator 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 confuse drivers behind you.

Anti-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 distribution (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 pedal. 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.

When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.

■

ABS

Anti-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 time or distance it takes 
to stop the vehicle. It only helps with steering control 
during hard braking.

In the following cases, your vehicle may need more 
stopping distance than a vehicle without the ABS:

•

When driving on rough road surfaces, including 
when driving on uneven surfaces, such as gravel or 
snow.

•

When tire chains are installed.

You may hear a motor sound coming from the front 
of the car while system checks are being performed 
immediately after turning the power system on or 
while driving. This is normal.

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.
