Honda CLARITY Fuel Cell 2021 Owner's Manual page 22

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 (P91)
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 after 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 exhaust 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 pipe 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.
