Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable materials left und er the hatch, causing a
fire. If you’ve parked y our vehicle for an extended

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.
