Electric Vehicle Precautions
High Voltage Components, High Voltage Cables and High Temperature 
Components
Electric vehicles have high voltage components (about 500 V maximum) such as the power control unit, High Voltage battery, high  voltage 
cables (identified by their orange covers), electric motor, and high temperature parts such as the radiator. Labels with handli ng 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 Electric dealer.

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.

uuCleaning uExterior Care
Maintenance
• Keep sufficient distance between the  cleaning nozzle and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to 
enter the vehicle interior.
• Do not spray high pressure water directly  into the motor compartment. Instead, 
use low pressure water.
• Do not spray water under the hood wh ere the electric motor and other high 
voltage system components are located. It could cause a malfunction.
• Do not spray water directly at the charging port.
A good coat of automotive body wax helps protect your vehicle’s paint from the 
elements. Wax will wear off over time and expose your vehicle’s paint to the 
elements, so reapply as necessary.
If you get coolant, or battery fluid on resi n coated parts, they may be stained or the 
coating may peel. Promptly wipe it aw ay using a soft cloth and clean water.
Wipe using a glass cleaner.

■Cleaning the Window
1 Applying Wax
NOTICE
Chemical solvents and strong cleaners  can damage 
the paint, metal, and plasti c on your vehicle. Wipe 
away spills immediately.
1 Maintaining the Bumpers an d Other Resin Coated Parts
Ask an authorized Honda Clar ity Electric dealer about 
the correct coating material  when you want to repair 
the painted surface of the parts made of resin.
1 Cleaning the Window
When you raise a wiper arm, you may inadvertently 
alter the position of the arm by applying undue force.
If you notice that an arm is  not in its proper return 
position, active the wipers once and they will 
automatically reset. 2 Wipers and Washers  P. 157
