Safety When Performing Maintenance
Some of the most important safety precautions are given here. However, we cannot
warn you of every conceivable hazard that can arise in performing maintenance.
Only you can decide whether you should perform a given task. • To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood and hatch.
uHeat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
uOnly operate the engine if th ere is sufficient ventilation.
• The vehicle must be in a stationary condition.
uMake sure your vehicle is parked on le vel ground, the parking brake is set, and
the power system is turned off.
• Be aware that hot parts can burn you.
uMake sure to let the power system, including the engine and exhaust system,
cool thoroughly before touching vehicle parts.
• Be aware that moving parts can injure you.
uDo not activate the power system unle ss instructed, and keep your hands and
limbs away from moving parts. When the power system is on, the engine can
automatically start, or the radiator fa n may start operating without the engine
running.

■Checking the Coolant
1Cooling System
NOTICE
Genuine Acura engine cool ant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout -31°F (-35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult an authorized
Acura NSX dealer for details.If Acura antifreeze/coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Ac ura coolant can result in
corrosion, causing the coo ling system to malfunction
or fail. Have the cooling system flushed and refilled
with Acura antifreeze/cool ant as soon as possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. Th ey may not be compatible
with the coolant or with the engine components.
3WARNING
Removing the reserve tank cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the reserve tank
cap.

Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■ Inflation guidelines
Properly inflated tires provide the best combination of handling, tread life, and
comfort. Refer to the driver’s doorjamb labe l or specifications page for the specified
pressure.
Underinflated tires wear unev enly, adversely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more prone to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month or before long trips, use a gauge to measure the pressure in all
tires. Even tires in good condition can lose 1 – 2 psi (10 – 20 kPa, 0.1 – 0.2 kgf/cm2
)
per month.
■ Inspection guidelines
Every time you check inflation, also examine the tires and valve stems. Look for: • Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,
splits, or cracks in the side of the tire . Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have an authorized Acura NSX dealer check the wheel
alignment.
• Excessive tread wear.
2 Wear Indicators P. 412
• Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as 4 – 6 psi (30 – 40 kPa, 0.3 – 0.4 kgf/cm 2
) higher than
if checked when cold.
Have an authorized Acura NSX dealer check the tires
if you feel a consistent vi bration while driving. New
tires and any that have be en removed and reinstalled
should be properly balanced.
3WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding ti re inflation and
maintenance.

Maintenance
Exterior Care
Dust off the vehicle body after you drive. Regularly inspect your vehicle for scratches
on painted surfaces. A scratch on a painted surface can result in body rust. If you
find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions: • If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
Do not use an automated car wash. • Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. St anding too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.

1Washing the Vehicle
Do not spray water into the air intake vents. It can cause a malfunction.
Do not spray water onto the capless unit when the
fuel fill door is open. It ca n cause damage to the fuel
system or engine. If you need to lift the wiper arms away from the
windshield, first set the wiper arms to the
maintenance position.

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.

1Refueling from a Portable Fuel Container
NOTICE
Do not insert the nozzle of a portable fuel container
or any funnel other than the one provided with your
vehicle. Doing so can damage the fuel system.
Do not try to pry open or push open the filler opening
with foreign objects. This can damage the filler
opening and its seal.
Make sure the fuel in the portable fuel container is
gasoline before you refuel.
3WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel. • Turn the power system off, and keep
heat, sparks, and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
