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 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 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.

Fuel Information

NOTICE

We 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.

How to Refuel

Driving

How to Refuel

Your fuel tank is not equipped with a fuel filler 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.

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.

1

How to Refuel

The fuel filler opening is designed to accept only service 
station filler nozzles for refueling. Use of smaller 
diameter tubes (e.g., those used 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.

If the filler 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 filler 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 P. 584

WARNING

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.

 emissions is dependent on several 

factors, including driving conditions, load weight, idling time, driving habits, and 
vehicle condition. Depending on these and other factors, you 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, replacement, or repair of 
emissions control devices and systems may be 
done by any automotive repair establishment or 
individuals using parts that are “certified” to 
EPA standards.

According to state and federal regulations, failure to 
perform maintenance on the maintenance main 
items marked with # will not void your emissions 
warranties. However, all maintenance services should 
be performed in accordance with the intervals 
indicated by the multi-information display.

2 Maintenance Service Items P. 500

If you want to perform complex maintenance tasks 
that require more skills and tools, you can purchase a 
subscription to the Service Express website at 
www.techinfo.honda.com.

2 Authorized Manuals P. 595

If you want to perform maintenance yourself, make 
sure that you have the necessary tools and skills first.
After performing maintenance, update the records in 
the separate maintenance booklet.

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 explosion, keep cigarettes, sparks, and flames 

away from the 12-volt battery, all High Voltage system, 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 12-volt 

battery or compressed air.

• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.

u

Only operate the engine if 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 power system is turned off.

• Be aware that hot parts can burn you.

u

Make 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.

u

Do not activate the power system unless instructed, and keep your hands and 
limbs away from moving parts. When the power mode is on, the engine can 
automatically start, or the radiator fan may start operating without the engine 
running.

from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).

*4: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperature. 

This requires transmission fluid changes more frequently than recommended by the Maintenance 
Minder. If you regularly drive your vehicle under this condition, have the transmission fluid changed at 
30,000 miles (48,000 km), then every 25,000 miles (40,000 km).

*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under

-20°F, -29°C), replace every 60,000 miles (100,000 km).

*6: Driving in mountainous areas at very low vehicle speeds results in higher level of mechanical (Shear) 

stress to fluid. This requires Twin Motor Unit fluid changes more frequently than recommended by the 
Maintenance Minder. If you regularly drive your vehicle under this condition, have the Twin Motor Unit 
fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
