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 J2842.1 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.

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 water into the engine compartment.
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 gasoline, oil, coolant, or batter y 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.

NOTICE
Chemical solvents and st rong 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 Clarity Plug- In Hybrid 
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. 166
