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.

not come off when the engine vibrates. Also be
careful not to tangle the ju mper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
12-volt battery performa nce degrades in cold
conditions and may prevent the engine from starting.
3WARNING

follow the correct procedure, seriously
injuring anyone nearby.
Keep all sparks, open flames, and smoking

Emissions Testing
Testing of Readiness Codes
Your vehicle has readiness codes as part of the onboard self diagnostic system.
Some States use these codes for testing to
verify whether your vehicle’s emissions
components are working properly.
The codes may not be read properly if te sting is performed just after the 12-volt
battery has gone dead or been disconnected.
To check if they are set, set the powe r mode to ON, without turning the power
system on. The malfunction indicator lamp will come on for several seconds. If it
then goes off, the readiness co des are set. If it blinks five times, the readiness codes
are not set.
If you are required to have your vehicle te sted before the readiness codes are ready,
prepare the vehicle for retest ing by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the power system off for six hours or more.
3. Make sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4. Start the engine without touching the ac celerator pedal, and let it idle for 20
seconds.
5. Keep the vehicle in
(P . Increase the engine speed to 2,000 rpm, and hold it there
for about three minutes.
6. Let the engine idle with your foot off the accelerator for 20 seconds.
1Testing of Readiness Codes
The readiness codes are erased when the 12-volt
battery is disconnected, and set again only after
several days of driving under a variety of conditions.
If a testing facility determines that the readiness
codes are not set, you may be requested to return at
a later date to complete the test.
If the testing facility determines the readiness codes
are still not set, see an authorized Acura NSX dealer.
