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
Storage
Vehicle Storage
If you need to park your vehicle for an extended period (more than one month),
there are several things you should do to pr epare it for storage. This helps reduce
possible deterioration of vehicle compone nts and overall condition, which allows
you to get the vehicle back on the road with minimal delay. These are:
• If possible, store your NSX in a garage or enclosed area.
• Fill the fuel tank completely.
• Change the engine oil and filter.
• Wash and dry the exterior completely.
• Clean the interior. Make sure the carpetin g, floor mats, etc., are completely dry.
• Put the transmission in
(P.
Release the parking brake.
• Leave one window open slightly (if the vehicle is being stored indoors).
• To maintain the low-voltage 12-volt battery, connect it to an accessory battery
charger. For more information on how to maintain your 12-volt battery, consult
an authorized Ac ura NSX dealer.
2Checking the 12-Volt Battery P. 421
•If the vehicle is to be stored for a longer period of time, it should be supported on
jack stands to raise the tires off the ground to prevent tire flat spotting.
2Handling of the Jack P. 448
•Support the front wiper blade arms with a folded towel or rag so they do not
touch the windshield.
• Cover the vehicle with a “breathable” co ver, one made from a porous material
such as cotton. Nonporous materials (such as plastic sheeting) may trap moisture,
which can damage the paint.
• If possible, remove the vehicle from the garage or enclosed area, remove
covering, and periodically run the en gine until it reaches full operating
temperature (the cooling fa n cycles on and off twice).
Preferably, do this once a month.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a sma ll puncture, from a small nail for instance,
you can use the temporary tire repair kit so that you can drive to the nearest service
station for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface. Apply the parking
brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact an authorized Acura NSX dealer or a
roadside assistant to have the vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4 mm).•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.
