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 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 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 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 informati on 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 gaso line. 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.

Maintenance
Engine Coolant
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolan t level every time you refuel or you
charge the High Voltage battery. Check the re serve tank first. If it is completely
empty, also check the coolant level in the radiator. Add the engine coolant
accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
NOTICE
Genuine Honda engine coolan t is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about −31°F (−35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult an authorized
Honda Clarity Plug-In Hybrid dealer for details.
If Honda antifreeze /coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda antifreeze/coolant as soon as
possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. They may not be compatible
with the coolant or with the engine components.
