RefuelingFuel 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 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 lev el 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 in formation 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.■Fuel tank capacity: 17.2 US gal (65 liters)Unleaded premium gasoline, pump octane number 91 or higher
1Fuel InformationNOTICEWe 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 recommend 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.
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 gasoline containing methanol.
If you notice any undesirable operating symptoms, try
another service station or switch to another brand of
gasoline.

uuRefueling uHow to Refuel
Driving
How to RefuelYour fuel tank is not equipped with a fuel fill cap. You can insert the filler nozzle
directly into the filler pipe. 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 engine.
3. Press the fuel fill door release button.
u The 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.
u Make sure that the end of the filler
nozzle goes down along with the filler
pipe.
u Keep the filler nozzle level.
u When the tank is full, the filler nozzle will
click off automatically.
u After filling, wait about five seconds
before removing the filler nozzle.
5. Shut the fuel fill door by hand.
1How to Refuel
Only a service station filler nozzle can be used.
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 af ter the nozzle has
automatically stopped. Additional fuel can exceed
the full tank capacity.
If you have to refuel your vehicle from a portable
container, use the funnel provided with your vehicle. 2 Refueling From a Portable Fuel Container

WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
• Stop the engine, and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

Fuel EconomyImproving Fuel EconomyFuel 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.■

Safety When Performing MaintenanceSome of the most important safety precautions are given here.
However, we cannot warn you of every conc eivable hazard that can arise in
performing maintenance. Only you can decide whether or not you should perform
a given task.
• To reduce the possibility of fire or explosion, keep cigarettes, sparks, and flames
away from the battery and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them causing a fire.
• To clean parts, use a commercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the battery or
compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Operate the engine only when there is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on level ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not start the engine unless instructed, and keep your hands and limbs away
from moving parts.
