Maintenance
• Keep sufficient distance between the cleaning nozzl e 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 co mpartment. Instead,
use low pressure water.
• Do not spray high pressure water direct ly around the hydrogen fuel lid and
ventilation duct.
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 inverter coolant or battery fluid on resin coated parts, they may be stained
or the coating may peel. Promptly wipe it away using a soft cloth and clean water.
Wipe using a glass cleaner.

1 Maintaining the Bumpers an d Other Resin Coated Parts
Ask an authorized Honda Cl arity Fuel Cell dealer
about the correct coating ma terial when you want to
repair the painted surface of the parts made of resin.
1Cleaning 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.
