Fuel Information ■Fuel requirement
Use of lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
We recommend that you use a pump octane of 93 or higher to maximize the
performance of the engine.
Use of gasoline with a pump octane less than 91 can lead to engine damage. ■ Top tier detergent gasoline
Because the level of detergency and additi ves in gasoline vary in the market, Acura
endorses the use of “TOP TIER Detergent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard jointly established by leading automotive
manufacturers to meet the needs of today’s advanced engines.
Qualifying gasoline retailers will, in most cases, identify their gasoline as having met
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is
guaranteed to contain the proper level of de tergent additives and be free of metallic
additives. The proper level of detergent additives, and absence of harmful metallic
additives in gasoline, help avoid build-up of deposits in your engine and emission
control system.
For further important fuel-related informati on for your vehicle, or on information on
gasoline that does not contain MMT, visit Acura Owners at owners.acura.com. In
Canada, visit www.acura.ca for additional informati on on gasoline. For more
information on top tier gasoline, visit www.toptiergas.com.

1Fuel Information
NOTICE
We recommend quality ga soline containing
detergent additives that help prevent fuel system and
engine deposits. In addition, in order to maintain
good performance, fuel economy, and emissions control, we strongly reco mmend the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is
available.
Use of gasoline with these additives may adversely
affect performance, a nd cause the malfunction
indicator lamp on your inst rument panel to come on.
If this happens, contact an authorized Acura NSX
dealer for service.
Some gasoline today is blended with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
by volume. Do not use ga soline containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.

How to Refuel
Your fuel tank is not equipped with a fuel fill cap. You can insert the filler nozzle
directly into the filler neck. The tank seals itself again when you pull out the filler
nozzle.
1.Stop your vehicle with the service station
pump on the left side of the vehicle in the rear.
2. Turn off the power system.
3. Press the fuel fill door release button.
uThe fuel fill door opens.
4. Place the end of the filler nozzle on the
lower part of filler opening, then insert it
slowly and fully.
uMake sure that the end of the filler
nozzle goes down along with the filler pipe.
uKeep the filler nozzle level.
uWhen the tank is full, the filler nozzle will
click off automatically.
uAfter filling, wait about five seconds before removing th e filler nozzle.
5. Shut the fuel fill door by hand.
1How to Refuel The fuel filler opening is designed to accept only
service station filler nozzles for refueling. Use of
smaller diameter tubes (e.g ., to siphon fuel for other
uses) or other non-service station devices can damage the area in and around the filler opening.
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel does not overflow as a result
of changes in air temperature.
Do not continue to add fuel after the nozzle has
automatically stopped. Addi tional fuel can exceed
the full tank capacity.
If the fuel nozzle keeps turning off when the tank is not
full, there may be a problem with the pump’s fuel vapor
recovery system. Try filling at another pump. If this does not
fix the problem, consult an authorized Acura NSX dealer.
If you have to refuel yo ur vehicle from a portable
container, use the funnel pr ovided with your vehicle.

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.

Cooling System
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank. Add the engine coolant accordingly.1. Make sure the engine and radiator are cool.
2. Open the hatch.

4. Check the amount of c oolant in the reserve
tank.
uIf the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
5. Inspect the cooling system for leaks.
Specified coolant: Acura Long Life Antifreeze/Coolant Type 2
■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.

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.
