12-Volt Battery
Checking the 12-Volt Battery
Check the battery terminals for corrosion
monthly.
The battery is protected by a cover.
Remove the cover by pressing the tabs.
Slide the terminal cover on your vehicle’s 12-
volt battery positive + terminal.
The battery condition is monitored by the
sensor on the negative terminal. If there is a
problem with the sensor, the warning
message on the driver information interface
will let you know. Have your vehicle checked
by an authorized Acura NSX dealer.
If your vehicle’s battery is disconnected or goes dead:
• The audio system is disabled.
2 Reactivating the audio system P. 164
•The clock resets.2 Clock P. 104
•The navigation system* is disabled.2 Refer to the Navigation System Manual
Charging the AGM Battery
AGM labeled batteries can be damaged if im properly charged. For more information
on how to charge an AGM battery, cons ult an authorized Acura NSX dealer.
112-Volt Battery
WARNING: Battery post, terminals,
and related accessories contain lead
and lead compounds.
Wash your hands after handling.
When you find corrosion, cl ean the battery terminals
by applying a baking powder and water solution.
Clean terminals with a damp towel. Cloth/towel dry
the battery. Coat the terminals with grease to help
prevent future corrosion.
When replacing the battery, the replacement must be
of the same specifications.
Consult an authorized Acura NSX dealer for more
information.
3WARNING
The battery gives off explosive hydrogen
gas during normal operation.
A spark or flame can cause the battery to
explode with enough force to kill or
seriously hurt you.
When conducting any battery maintenance,
wear protective clothing and a face shield,
or have a skilled technician do it.

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 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 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 the ground to prevent tire flat spotting.
2Handling of the Jack P. 444
•Support the front wiper blad e 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.

If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a sma ll puncture, from a small nail for instance,
you can use the temporary tire repair kit so that you can drive to the nearest service
station for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface. Apply the parking
brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact an authorized Acura NSX dealer or a
roadside assistant to have the vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4 mm).•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.
When the puncture is:Kit Use

6. Plug in the compressor to the accessory
power socket.
u Be careful not to pinch the cord in a
door or window.
2 Accessory Power Socket P. 154
7.Turn the power system on.
u Keep the power system on while
injecting sealant and air.
2 Carbon Monoxide Gas P. 67
8.Turn the air compressor on to inflate the
tire.
u The compressor starts injecting sealant
and air into the tire.
9. After the air pressure reaches 32 psi (220
kPa), turn off the compressor.
1Injecting Sealant and Air
NOTICE
Do not operate the temporary tire repair kit compressor
for more than 15 minutes. The compressor can overheat
and become permanently damaged.
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begi n to rise again as the tire
is inflated with air. This is normal. To accurately measure
the air pressure using the ga uge, turn the air compressor
off only after the sealant injection is complete.
If the required air pressure is not reached within 15
minutes, the tire may be too severely damaged for
the kit to provide the necessa ry seal and your vehicle
will need to be towed.
See an authorized Acura NSX dealer for a replacement
sealant bottle and proper disposal of an empty bottle.
3WARNING
Running the engine with the vehicle in an
enclosed or even partly enclosed area can
cause a rapid build-up of toxic carbon
monoxide.
Breathing this colorless, odorless gas can
cause unconsciousness and even death.
Only run the engine to power the air
compressor with th e vehicle outdoors.

4. Recheck the air pressure using the gauge
on the air compressor.
u Do not turn the air compressor on to
check the pressure.
5. If the air pressure is:
• Less than 19 psi (130 kPa):
Do not add air or continue driving. The
leak is too severe. Call for help and have
your vehicle towed.
2 Emergency Towing P. 462
•32 psi (220 kPa) or more:
Continue driving for another five
minutes or until you reach the nearest
service station if less than five minutes
away. Do not exceed 50 mph (80 km/h).
u Stop and check the air pressure again. If
the air pressure does not go down after
the five minute drive, you do not need to
check the pressure any more. Drive to
the nearest service station to fix or
replace the tire.
