Quick Reference Guide
Fuel Cell Insulating Fluid
Fuel cell insulating fluid (FC insulating fluid) uses a specifically designed fluid with high electrical insulation properties in order to safely cool
the fuel cell.
Never add water, other commercial coolants, or genuine Honda inverter coolant to the cooling system. Doing so will cause damage to the
fuel cell.
Consult an authorized Honda Clarity Fuel Cell dealer to replenish or change the fuel cell insulating fluid.

Quick Reference Guide
Ion Exchanger
An ion exchanger is installed in the fluid lines for the fuel cell in order to maintain the
insulation properties of the fuel cell insulating fluid (FC insulating fluid).
If the message Service Due Soon A appears on the driver information interface, ion
exchange filter replacement is necessary. Be sure to consult an authorized Honda Clarity
Fuel Cell dealer. 2 Indicators (P89)
Exhaust Pipe
Water is expelled from the tail pipe while the vehicle is running or while the High Voltage
battery is being charged. This also happens af ter the vehicle has been running or when you
shut down the FC system by setting the power mode to OFF. If you stand to the left rear of
the vehicle, you may be sprayed by this waste water.
Never drink water expelled from the pipe. Though this water is harmless, it is not suitable
for drinking.
While the vehicle is parked during cold temperatures, the FC system may automatically turn
on and discharge water from the ex haust pipe. If this water is discharged as a vapor, it may
appear as a white mist. This, however, is not indicative of a problem.
Do not obstruct or block the exhaust pi pe as the FC system may stop working.
Maintenance, Repair, and Disposal
Always consult an authorized Honda Clarity Fuel Cell dealer regarding maintenance, repair,
and disposal.
Fuel cells and High Voltage batteries that have been removed from disposed vehicles are
collected through authorized Honda Clarity Fuel Cell dealers. Do not dispose of those
batteries yourself.
WARNING
Do not directly touch any water emissions
from the exhaust pipe.
Water created during FC power generation
is discharged from the exhaust pipe in the
form of either liquid (water) or gas (steam).
Directly touching this water may cause
burns.

●Appears when fuel cell and high voltage battery
temperature is low.●You cannot drive the vehicl e until the temperature of
the fuel cell and high voltage battery has increased.
Turn on the climate control system and wait until the
message disappears. u You can activate the climate control system with the

●It may take a longer time to st art in very cold conditions
or may not start at all until temperatures rise. If the
temperature of the fuel cell or the high voltage battery
drops below –4°F (–20°C), the fuel cells will not operate
and, as a result, the vehicl e will not start. Store the
vehicle in a garage or take another measure to insure
that temperature of the fuel cell and high voltage
battery do not fall below this temperature. If necessary,
consult an authorized Honda Clarity Fuel Cell dealer.
●Appears when the Fuel Cell Insulating Fluid level is
low.●Have your vehicle checked by an authorized Honda
Clarity Fuel Cell dealer immediately.

*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.
