Driving
Your vehicle is equipped with disc brakes at all four wh eels. 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 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 occasion al squeak or squeal when
you initially apply the brake pedal, this may be normal
and caused by high frequen cy vibration of the brake
pads against the rotating brake disc.
Constantly using the brak e 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.

Maintenance
The inside lenses of exterior lights (headlig hts, brake lights, etc.) may fog temporarily
if you have driven in the rain. Dew condensation also may build up inside the lenses
when there is a significant enough differe nce between the ambient and inside lens
temperatures (similar to vehicle windows fogging up in rainy conditions). These
conditions are natural processes, not stru ctural design problems in the exterior
lights.
Lens design characteristics may result in mo isture developing on the light lens frame
surfaces. This also is not a malfunction.
However, if you see large amounts of wa ter accumulation, or large water drops
building up inside the lenses, have your vehicle inspected by an authorized Acura
NSX dealer.
Keep brake pads and rotors free of substances that are either abrasive or oil based,
as these substances can re duce brake system performance.
NSX brake pads and disks have a high meta llic content. Under certain conditions
these pad and disks may rust to varying degrees, which may cause a clunk noise or
rubbing sound if parked when brakes become wet. This is normal for brakes with
high friction pads and it does not affect operation of the brakes.
To prevent the iron contained in the brake pads and rotors from rusting and sticking,
brakes should be dried before parking the ve hicle after driving on wet roads or after
washing the vehicle (especially before long -term storage). To dry the brake pads and
rotors, drive the vehicle at a low sp eed and apply the brakes several times.
By regularly applying strong pressure to the brakes, you can reduce corrosion
buildup on the brake pads and rotors.

1 Brake Maintenance
Brake maintenance require s specialized knowledge.
We recommend maintenance to be carried out by an
authorized Acura NSX dealer.
1 Maintenance of Brake Surfaces
Brakes can be dried by driv ing on a dry road for few
miles/kilometers, and a pplying the brake pedal
normally, based on traffic and road conditions. These
steps help maintain br ake system performance.

Maintenance
Keep the brake pads and rotors free of subs tances that are either abrasive or oil
based, as these substances can reduce br aking power. After driving in the presence
of salt and/or sand, briefly wash the ro tor/pad surfaces with low-pressure water,
then allow the brake system to dry. To dry the brake pads and rotors, drive the
vehicle at a low speed and apply the brakes several times.
Refer to the color code label and the te mperature notice label affixed to the
underside of the hood before painting the vehicle.
