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.
