Fuel Information
■Fuel recommendation
Use of a lower octane gasoline can cause oc casional metallic knocking noise in the 
engine and will result in decreased engine performance.
Use of a gasoline with a pump octane less than 87 can lead to engine damage.
The use of regular unleaded gasoline can  cause metallic knocking noises in the 
engine and will result in decreased engine performance.
■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 ad ditives, 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 informati on on gasoline. For more 
information on top tier gasoline, visit  www.toptiergas.com.
■Fuel tank capacity: 19.5 US gal (73.8 L)
Unleaded premium gasoline, pump octane number 91 or higher
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  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 gaso line containing methanol. 
If you notice any undesira ble operating symptoms, try 
another service station or sw itch to another brand of 
gasoline.

Main 
Item
*1: If the message 
Maintenance Due Now does not appear more than 12 months after the display 
is reset, change the engine oil every year.
# : See information on maintenance and emissions warranty.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and  from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
CODEMaintenance Main Items
A
●Replace engine oil*1
B●Replace engine oil*1 and oil filter●Inspect front and rear brakes●Check expiration date for tire repair kit bottle*
●Inspect tie rod ends, steering gearbox, and boots●Inspect suspension components●Inspect driveshaft boots●Inspect brake hoses and li nes (Including ABS/VSA®)●Inspect all fluid levels and condition of fluids●Inspect exhaust system#
●Inspect fuel lines and connections#
*4: Driving in mountainous areas at very low vehicle speeds or trailer towing 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 these conditions, have the transmission 
fluid changed at 30,000 miles (48,000 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 or trailer towing results in higher level of 
mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than 
recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, 
have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

uuChecking and Maintaining Tires uWear Indicators
Maintenance
Wear Indicators
The groove where the wear indicator is 
located is 1/16 inch (1.6 mm) shallower than 
elsewhere on the tire. If the tread has worn so 
that the indicator is ex posed, replace the tire. 
Worn out tires have po or traction on wet 
roads.
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road 
conditions, vehicle loading, inflation pressure, maintenance history, speed, and 
environmental conditions (even wh en the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is 
recommended that you have annual inspections  performed once the tires reach five 
years old. All tires, including the spare
*, should be removed from service after 10 
years from the date of manufacture, regardle ss of their condition or state of wear.
