Quick Reference Guide
High Voltage Components, High Voltage Cables and High Temperature
Components
Fuel cell vehicles have high voltage components (about 500 V maximum) such as the FC stack, FCVCU, High Voltage battery, power control
unit, high voltage cables (identified by their orange covers), el ectric motor, and high temperature parts such as the radiator. Labels with
handling warnings are attached to these components.
WARNING
This vehicle has high voltage circuits and
parts. Failure to observe the following
precautions can result in burns or electric
shock.
●Do not remove, disassemble, or replace
the high voltage parts, cables (orange) or
their connectors.
●Never touch the High Voltage battery
service plugs.
In an emergency or during maintenance or
repair, the service plugs are removed to cut
off the electric flow from the battery. These
plugs are in contact with the battery and
can cause severe electric shock if not
handled properly.
Only a qualified technician should handle
any electrical equipment. For inspection
and repair, consult an authorized Honda
Clarity Fuel Cell dealer.

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 cool ant 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.
