Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, the Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditio ning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filters
The climate control system is equipped wi th dust and pollen filters that collect
pollen, dust, and other debris in the air. The Maintenance Minder TM
messages will let
you know when to replace the filters.
We recommend that you replace the dust an d pollen filters sooner when using your
vehicle in areas with high concentrations of dust.

Exterior Care
Dust off the vehicle body after you drive. Regularly inspect your vehicle for scratches
on painted surfaces. A scratch on a painted surface can result in body rust. If you
find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions: • If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
Do not use an automated car wash. • Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. St anding too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.

Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lo se their luster or appear burn ished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.

Maintenance
The inside lenses of exterior lights (headli ghts, 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 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 strong pressure to the brakes, you can reduce corrosion
buildup on the brake pads and rotors.

Keep the brake pads and rotors free of substances 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.

Accessories and Modifications
Accessories
When installing accessories, check the following:
• Do not install accessories on the windshie ld. They can obstruct your view and
delay your reaction to driving conditions.
• Do not install any access ories over areas marked SRS AIRBAG, on the sides or
backs of the seats, on front or side pillars, or near the side windows.
Accessories installed in these areas may interfere with proper operation of the
vehicle’s airbags or may be propelled into you or another occupant if the airbags
deploy.
• Be sure electronic accessories do not over load electrical circuits or interfere with
proper operation of your vehicle. 2 Fuses P. 457
• Before installing any electronic accessory, have the installer contact an authorized
Acura NSX dealer for assistance. If possibl e, have an authorized Acura NSX dealer
inspect the final installation.

Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Acura pa rts or accessories that may have a similar
effect. Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is properly installed and maintained, and do not
make any modification to your vehicle or its systems that might cause your vehicle
to no longer meet federal, state, pr ovince, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1 962 connector) installed on this vehicle
is intended to be used with automobile system diagnostic devices or with other
devices that Acura has approved. Use of any other type of device may adversely
affect the vehicle’s electronic systems or allow them to be compromised, possibly
resulting in a system malfunction, drained battery, or other unexpected problems. Do not modify or attempt to repair your vehicle’s high-voltage hybrid power system
or otherwise modify vehicle electrical syst ems. Disassembling or modifying electrical
equipment can result in a crash or a fire.
If you ever need to replace your vehicle' s high-voltage battery assembly outside of
warranty coverage, we highly recommend that you only use a genuine Acura high-
voltage battery assembly. Genuine Acura high-voltage battery assemblies are
designed to work with your vehicle's hybrid power system and have been designed,
engineered and manufactured to avoid overcharging situations. Non-genuine high-
voltage battery assemblies may not have b een similarly designed, engineered and
manufactured, and installation of such assemblies could result in overcharging, fires,
loss of power, or other conditions that may increase the likelihood of a crash or
injury.

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 prepare it for storage. This helps reduce
possible deterioration of vehicle components 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 carpeti ng, floor mats, etc., are completely dry.
• Put the transmission in
(P .
Release the parking brake.
• Leave one window open slightly (if th e vehicle is being stored indoors).
• To maintain the low-voltage 12-volt batte ry, connect it to an accessory battery
charger. For more information on how to maintain your 12-volt battery, consult
an authorized Acura NSX dealer. 2 Checking the 12-Volt Battery P. 417
• 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 th e ground to prevent tire flat spotting.
2 Handling of the Jack P. 444
• 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 (suc h as plastic sheeting) may trap moisture,
which can damage the paint.
• If possible, remove the vehicle from th e garage or enclosed area, remove
covering, and periodically run the engi ne until it reaches full operating
temperature (the cooling fa n cycles on and off twice).
Preferably, do this once a month.
