490 uu Maintenance Under the Hood u Cooling System
Maintenance Cooling System Coolant is used to reduce the temperature of the high voltage battery and inverter
coolant. When checking the c oolant level, make sure to follow the procedures listed
below. If the coolant level is below the MIN mark, have your vehicle inspected by an
authorized Honda Clarity Plug-In Hybrid dealer.
1. Check the fluid level in the tank.
2. If the coolant level has dropped below the
MIN level, have your vehicle serviced at an
authorized Honda Clarity Plug-In Hybrid
dealer.
u Only a properly trained technician can
refill the coolant an d check the system
for leaks.Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
■ Checking the Inverter Coolant Level 1 Cooling System NOTICE
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 Hybr id dealer for details.
Only use the genuine Honda coolant.

502 uu Checking and Maintaining Tires u DOT Tire Quality Grading (U.S. Vehicles)
Maintenance DOT Tire Quality Grading (U.S. Vehicles) The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance a ccording to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on the tire sidewall
between tread shoulder an d maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested un der controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.■ Uniform Tire Quality Grading
■ Treadwear 1 Uniform Tire Quality Grading
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.18 CLARITY PHEV CSS-31TRW6000.book 502 ページ ２０１７年８月３１日　木曜日　午後２時４９分

504 uu Checking and Maintaining Tires u Wear Indicators
Maintenance Wear Indicators The groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower than
elsewhere on the tire. If the tread has worn so
that the indicator is ex posed, replace the tire.
Worn out tires have poor traction on wet
roads.
Tire Service Life The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pre ssure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular in spections and inflation pres sure maintenance, it is
recommended that you have annual inspecti ons performed once the tires reach five
years old. All tires should be removed fro m service after 10 years from the date of
manufacture, regardless of their condition or state of wear. Example of a Wear

Maintenance
Climate Control System Maintenance Air Conditioning To ensure proper and safe operation, the Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditio ning evaporator (coo ling 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.
