Genuine Honda engine coolan t is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about −31°F (−35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult an authorized
Honda Clarity Plug-In Hybrid dealer for details.

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.

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

1 Cleaning the Window
When you raise a wiper arm, you may inadvertently
alter the position of the arm by applying undue force.

position, active the wipers once and they will
automatically reset. 2 Wipers and Washers P. 166
