Fuel Information
■Fuel recommendation
Use of a lower octane gasoline can cause a persistent, heavy metallic knocking noise 
that can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additives in gasoline vary in the market, Honda 
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 ca ses, 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-rel ated information for your vehicle, or on information on 
gasoline that does not contain MMT, visit  www.hondacars.com. In Canada, visit 
www.honda.ca  for additional information on gasoline. For more information on top 
tier gasoline, visit www.toptiergas.com .
■Fuel tank capacity: 7.0 US gal (26.5 liters)
Unleaded gasoline, pump octane number 87 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 an authorized  Honda Clarity 
Plug-In Hybrid 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.

*2: 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).
*3: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. 
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 
every 47,500 miles (75,000 km) or 3 years.
*4: If a Maintenance Minder message does not appear more than 36 months after the display for item 7 is  reset, change the brake fluid every 3 years.

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 poor 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 pre ssure, maintenance history, speed, and 
environmental conditions (even when the tires are not in use).
In addition to regular in spections and inflation pres sure maintenance, it is 
recommended that you have annual inspecti ons performed once the tires reach five 
years old. All tires should be removed fro m service after 10 years from the date of 
manufacture, regardless of their condition or state of wear.
