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.
