For your safety, make sure you have a clear view 
through all the windows before driving.
Do not set the temperatur e near the upper or lower 
limit.
When cold air hits the windshield, the outside of the 
windshield may fog up.
If the side windows fog up,  adjust the vents so that 
the air hits th e side windows.
1To rapidly defrost the windows
After defrosting the windows, switch over to fresh air 
mode or auto mode.
If you keep the system in recirculation mode, the 
windows may fog up from humidity. This impedes 
visibility.

Maintenance
Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE 
J2845) recommends that the refrigerant  system only be serviced by trained and 
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one 
removed from a used or salvaged vehicle.
New replacement mobile air conditioning  evaporators must be certified (and 
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The climate control system is equipped with a dust and pollen filter that collects 
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let 
you know when to replace the filter.
We recommend that you replace the dust a nd pollen filter sooner when using your 
vehicle in areas with high concentrations of dust.
1 Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from  venting, never replace the 
evaporator with one re moved from a used or 
salvaged vehicle.
Refrigerant in your  vehicle’s air conditioning system is 
flammable and can be igni ted during servicing if 
proper procedures  are not followed.
The air conditioner labe l is found under the hood:

2 Specifications  P. 530
1Dust and Pollen Filter
Using an air freshener  may reduce the deodorizing 
effect of the dust and polle n filter, and may reduce its 
life.
If the airflow from the climate control system 
deteriorates noticeably, and the windows fog up 
easily, the filter may need to be replaced. Please 
contact an authorized Honda  Clarity Fuel Cell dealer 
for replacement.
The allerfree hi gh retention deodor ization filter 
collects pollen and dust, has allergen treatment 
ability and reduces exhaus t gas odor that may be 
present in the air.
