Winter Tires
If driving on snowy or frozen roads, mount all-season marked M+S tires, snow tires,
or tire chains; reduce speed; and maintain sufficient distance between vehicles when
driving.
Be particularly careful wh en operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all-season tires when necessary or according to the law.
When mounting, refer to the following points.
For winter tires:
• Mount the tires to all four wheels.
For tire chains:
• Install them on the rear tires only.
• Because your vehicle has limited tire clea rance, we strongly recommend using the
chains listed below:
*1:Tire chains to be used only on optional 295/30R20 winter tires.
*2:Tire chains to be used only on optional 305/30R20 winter tires.
• Follow the chain manufactur er’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not touch the brake lines or suspension.
• Drive slowly.
Recommended Winter Tires:
•Michelin Alpin PA4
Front: 245/35R19 (93W)
Rear: 295/30R20 (97V)
• Pirelli SottoZero 3
Front: 245/35R19 (93W)
Rear: 305/30R20 (103W)
• Auto-trac 232405*1
•K-Summit K-44*2

NOTICE
Traction devices that are the wrong size or improperly
installed can damage your vehicle’s brake lines,
suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
When tire chains are mounted, follow the chain
manufacturer’s instructi ons regarding vehicle
operational limits.
If your vehicle is equipp ed with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact an
authorized Acura NSX dealer.
3WARNING
Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instruction s in this owner’s
manual regarding the selection and use of
tire chains.

uuCleaning uExterior Care
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 structural design problems in the exterior
lights.
Lens design characteristics ma y result in moisture 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 reduce 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 pa ds 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 str ong 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 braking 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 temperature notice label affixed to the
underside of the hood before painting the vehicle.
