*1: 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.
*2: 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 31,250 miles.
*3: If a Maintenance Minder message does not appear more than 12 year after the display for item 5 is reset, change Fuel Cell Insulating Fluid with “Fuel Cell Insulating Fluid - 50% prediluted formulation”
every 12 years.
*4: If a Maintenance Minder message does not appear more than 3 years after the display for item 7 is reset, change the brake fluid and replace air cleaner element every 3 years.

Maintenance
Inverter Coolant
This coolant is premixed with 50% an tifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the inverter cool ant level every time you refuel. Check
the reserve tank. Add the in verter coolant accordingly.
1. Make sure the motor 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: Ho nda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Inverter Coolant
NOTICE
Genuine Honda inverter coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout –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 Fuel Ce ll 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 fo r aluminum motors.
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 anti freeze/coolant as soon as
possible.
3WARNING
Removing the expansion tank cap while the
motor is hot can cause the coolant to spray
out, seriously scalding you.
Always let the motor and radiator cool
down before removing the expansion tank
cap.
