Fuel Information
■Fuel recommendation
Use of lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of gasoline with a pump octane less than 87 can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additives in gasoline vary in the market, Acura
endorses the use of “TOP TIER Deterg ent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard join tly established by leading automotive
manufacturers to meet the need s 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 detergent 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 information 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 information 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 a dealer for service.
Some gasoline today is ble nded with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
by volume. Do not use gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.

Maintenance
Cooling System
This coolant is premixed with 50% an tifreeze 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 first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Ac ura Long Life Antifreeze/Coolant Type 2
■Reserve Tank
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 a 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-Acur a coolant can result in
corrosion, causing the cooling 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. They may not be compatible
with the coolant or with the engine components.
3WARNING
Removing the radiator 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 radiator cap.
