Maintenance
Checking and Maintaining Tires Checking Tires To safely operate your vehicle, your tire s must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■ Inflation guidelines
Properly inflated tires provid e the best combination of hand ling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ifications page for the specified pressure.
Underinflated tires wear unev enly, adversely affect handli ng and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more pron e to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month or before long trips , use a gauge to measure the pressure in
all tires. Even tires in good condition can lose 1–2 psi (10–20 kPa, 0.1–0.2 kgf/cm 2
)
per month.
■ Inspection guidelines
Every time you check inflation, also examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tr ead. Replace the tire if you find any cuts,
splits, or cracks in the side of the tire . Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have an authorized H onda Clarity Plug-In Hybrid dealer check
the wheel alignment.
• Excessive tread wear. 2 Wear Indicators P. 504
• Cracks or other damage around valve stem. 1 Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm 2
) higher than if
checked when cold.
Whenever tire pressure is adjusted, you must
calibrate the TPMS.
2 TPMS Calibration P. 425
Have an authorized Honda Clarity Plug- In Hybrid
dealer check the tires if you feel a consiste nt vibration
while driving. New tires and any that have been
removed and reinstalled sh ould be properly balanced.3
WARNING Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding tire inflation and
maintenance.18 CLARITY PHEV CSS-31TRW6000.book 499 ページ ２０１７年８月３１日　木曜日　午後２時４９分

503uu Checking and Maintaining Tires u DOT Tire Quality Grading (U.S. Vehicles)
Maintenance
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified
government test surfaces of asph alt and concrete. A tire marked
C may have poor traction performance.
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat and its
ability to dissipate heat when te sted under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperature can cause the material of the tire to degenerate and
reduce tire life, and ex cessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.■ Traction
■ Temperature 1 Traction
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics. 1 Temperature
Warning: The temperature grade for
this tire is establishe d for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.18 CLARITY PHEV CSS-31TRW6000.book 503 ページ ２０１７年８月３１日　木曜日　午後２時４９分

505uu Checking and Maintaining Tires u Tire and Wheel Replacement
Maintenance
Tire and Wheel Replacement Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist (VSA ® ) system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
Make sure that the wheel’s specificati ons match those of the original wheels. 1 Tire and Wheel Replacement

WARNING Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or
killed.
Always use the size and type of tires
recommended in this owner’s manual.18 CLARITY PHEV CSS-31TRW6000.book 505 ページ ２０１７年８月３１日　木曜日　午後２時４９分

507uu Checking and Maintaining Tires u Winter Tires
Maintenance
Winter Tires If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires,
or tire chains; reduce speed; and maintain sufficient distance be tween vehicles when
driving.
Be particularly careful wh en operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season ti res when necessary or according to the law.
When mounting, refer to the following points.
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clea rance, we strongly recommend using the
chains listed below:
• Follow the chain manufactur er’s instruction when in stalling. Mount them as
tightly as you can.
• Check that the chains do not touc h the brake lines or suspension.
• Drive slowly.Cable-type: SCC Radial Chain SC1040 1 Winter Tires
NOTICE
Traction devices that are th e wrong size or improperly
installed can damage your vehicle’s brake lines,
suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
When tire chains are mounted, follow the chain
manufacturer’s instructi ons regarding vehicle
operational limits.
If your vehicle is equipp ed with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact an
authorized Honda Clarity Plug-In Hybrid dealer.3
WARNING Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instruction s in this owner’s
manual regarding the selection and use of
tire chains.18 CLARITY PHEV CSS-31TRW6000.book 507 ページ ２０１７年８月３１日　木曜日　午後２時４９分

517 uu Cleaning u Exterior Care
Continued
Maintenance
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lo se their luster or appear burn ished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.
The inside lenses of exterior lights (headlights, brake light s, etc.) may fog temporarily
if you have driven in the rain, or after the vehicle has been run through a car wash.
Dew condensation also may build up inside the lenses when there is a significant
enough difference between the ambient and inside lens temperatures (similar to
vehicle windows fogging up in rainy conditions). These conditions are natural
processes, not structural design problems in the exterior lights.
Lens design characteristics ma y result in moisture developing on the light lens frame
surfaces. This also is not a malfunction.
However, if you see large amounts of wa ter accumulation, or large water drops
building up inside the lenses, have your vehicle inspected by an authorized Honda
Clarity Plug-In Hybrid dealer.■ Maintaining Aluminum Wheels

Handling the Unexpected If a Tire Goes Flat Temporarily Repairing a Flat Tire If the tire has a large cut or is otherwise se verely damaged, you will need to have the
vehicle towed. If the tire only has a smal l puncture, from a nail for instance, you can
use the temporary tire repair kit so that you can drive to the nearest service station
for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface and apply the parking
brake.
2. Change the gear position to ( P
.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF
(LOCK). 1 Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact an authorized Honda Clarity Plug-In
Hybrid dealer or roadside assistance to have the
vehicle towed.
• The tire sealant has expired.
• More than one tire is punctured.
• The puncture or cut is larger than 3/16 inch (4 mm).
• The tire side wall is da maged or the puncture is
outside the contact area.
• Damage has been caused by driving with the tire
extremely under inflated.
• The tire bead is no longer seated.
• The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.When the puncture is: Kit Use
