Quick Reference Guide
Electricity Consumption and Driving Range
Driving range is dependent on driving conditions and climate control system use. Since the climate control system in this vehicle runs on 
electricity, it will consume electricity when in use. The climate  control system requires more electricity for heating than it does for cooling; 
therefore, when you use the heating function, especially when ambient temperatures are very low, the distance that you can travel on the 
remaining power will be shortened.
The meter below shows the driving range as well as the amount of electricity that has been consumed by the motor and the climat e control 
system.
Electricity Consumption  Indicator (ENERGY USAGE)
The meter shows the ratio between the energy which has been consumed by the 
climate control system ( CLIMATE) and the energy which has been consumed by 
the motor ( DRIVE).
Range Display
Displays the estimated driving range as well as 
the estimated additional  driving range if the 
climate control system is turned off.
To turn the climate control system off, press 
the  button.  2 Climate Control System  (P183)

Controls
■Switching the vent mode
1.Press the  CLIMATE  button.
2. Select a desired vent mode icon.
■A/C on and off
1.Press the  CLIMATE  button.
2. Select  On or  Off .
1Using Automatic Climate Control
When you unlock the doors with your remote, the 
driver’s ID (DRIVER 1 or DRIVER 2) is detected, and 
the climate control settings are turned to the 
respective mode automatically when you set the 
power mode to ON.
The High Voltage battery level being low may reduce 
the climate control system performance.
If any icons are not select ed within several seconds 
after the display is switched, it returns to the previous 
screen. In this case, press the  CLIMATE button again.
You can change the length of time the climate 
control display stays on. 2 Customized Features  P. 280
While ECON mode is active, the climate control 
system may have reduced  cooling performance.

Cooling System
Coolant is used to reduce the temperat ure of the high voltage battery, motor and 
related parts. When checking  the coolant level, make sure to follow the procedures 
listed below. If the cool ant level is below the MIN mark, have your vehicle inspected 
by an authorized  Honda Clarity Electric dealer.
1.Check the fluid level in the tank.
2. If the coolant level has dropped below the 
MIN  level, have your ve hicle serviced at an 
authorized Honda Clarity Electric dealer.
u Only a properly trained technician can 
refill the coolant and check the system 
for leaks.
1. Check the fluid level in the tank.

Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, the 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 conditio ning 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 an d 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:

1Dust and Pollen Filter
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 Electric dealer 
for replacement.
