Fuel Information
■Fuel recommendation
Your vehicle is designed to operate on premium unleaded gasoline with pump
octane of 91 or higher. If this octane grad e is unavailable, regular unleaded gasoline
with a pump octane of 87 or hi gher may be used temporally.
The use of regular unleaded gasoline can cause metallic knocking noises in the
engine and will result in decreased engine performance. The long-term use of
regular-grade gasoline can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additive s in gasoline vary in the market, Honda
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 need s of today’s advanced engines.
■Gasoline containing ethanol
Some gasoline today is blended with oxygen ates such as ethanol. Your vehicle is
designed to operate on oxygenated gasoline containing up to 10% ethanol by
volume. Do not use gasoline containing methanol. If you notice any undesirable
operating symptoms, try another service st ation or switch to another brand of
gasoline.
Premium unleaded gasoline, pump octane number 91 or higher
1 Fuel Information
NOTICEWe recommend quality gasoline 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, and cause the malfunction
indicator lamp on your instrument panel to come on.
If this happens, contact a dealer for service.

Driving
Qualifying gasoline retailers will, in most ca ses, identify their gasoline as having met
“TOP TIER Detergent Gasolin e” 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 My Acura 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.

4. Press the area indicated by the arrow to
release the fuel fill door. You will hear a
click.
5. Remove the fuel fill ca p slowly. If you hear a
release of air, wait until this stops, then turn
the knob slowly to open the fuel fill cap.
6. Place the fuel fill cap in the holder.
7. Insert the filler nozzle fully.
u When the tank is full, the fuel nozzle will
click off automa tically. This leaves space
in the fuel tank in case the fuel expands
with a change in the temperature.
8. After filling, replace the fuel fill cap,
tightening it until you hear it click at least
once.
u Shut the fuel fill door by hand.1How to Refuel
Use the master door lock switch to unlock the fuel fill
door.
The vehicle doors and fuel fill door automatically
relock if the remote unlock function is used. This can
be deactivated by briefly opening then closing the
driver’s door.
NOTICEThe fuel fill door and its latching mechanism can be
permanently damaged if the fuel fill door is forced
closed when the driver’s door is locked.
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.
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 a dealer.
Do not continue to add fuel after the nozzle has
automatically stopped. Ad ditional fuel can exceed
the full tank capacity.

Fuel Economy
Improving Fuel Economy
Fuel economy depends on several conditions, including driving conditions, your
driving habits, the condition of your vehicle, and loading. Depending on these and
other conditions, you may or may not achieve the rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
multi-information display.
• Use the recommended viscosity engine oil, displaying the API Certification Seal.
• Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy
Direct calculation is th e recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a si mulated test. For more
