■Periodic inspections
• Check the brake fluid level monthly.
2 Brake Fluid P. 496

Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires 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 handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more prone 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 Honda Clarity Plug-In Hybrid dealer check
the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 508
•Cracks or other damage around valve stem.
1Checking 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. 429
Have an authorized Honda Clarity Plug- In Hybrid
dealer check the tires if you feel a consistent vibration
while driving. New tires and any that have been
removed and reinstalled sh ould be properly balanced.
3WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instructions in this owner’s
manual regarding tire inflation and
maintenance.

Handling the Unexpected
When You Cannot Unlock the Fuel Fill Door
■What to Do When Unable to Unlock the Fuel Fill Door
If you cannot open the fuel fill door, use the following procedure. 1.Open the trunk and pull off the left inside
cover.
2. Pull the release lever towards you.
u The release lever opens the fuel fill door
when it is pulled.
3. Slowly remove the fuel fill cap by turning it
to the left. If you hear a release of pressure,
wait until it stops, then continue to slowly
remove the fuel fill cap.
2 How to Refuel P. 456
4.Add fuel very slowly.
u The automatic fuel tank vent valve does
not operate when the fuel fill door is
opened manually. Trying to add fuel too
rapidly when the vent valve is closed will
cause fuel vapors to be pushed out the
filler pipe and can cause a small amount
of liquid fuel to be spilled onto the
ground.
1 When You Cannot Unlo ck the Fuel Fill Door
The automatic fuel tank ve nt does not operate when
using the manual fuel door release. Gradually release
pressure by slowly turning th e fuel fill cap to the left.
If you hear a release of fuel vapors, wait until it stops,
then continue to slowly remove the fuel fill cap.
The malfunction indicator lamp may come on when
driving after you have refueled by manually opening
the fuel fill door.
2 If the Malfunction Indicator Lamp Comes
On or Blinks P. 551
After taking these steps, contact an authorized
Honda Clarity Plug-In Hybrid dealer to have the
vehicle checked.
3WARNING
Gasoline vapors in tank are under pressure.
• If using the manual fuel door release,
open the cap slowly to gradually release
pressure.
• Stop the engine, and keep all sparks,
heat, and flame away.
