Safety When Performing Maintenance
Some of the most important safe ty precautions are given here.
However, we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether you should perform a given
task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and pr otective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.

Maintenance
Oil Check
We recommend that you check the engine oil level every time you refuel or you
charge the High Voltage battery.
Park the vehicle on level ground.
Turn off the power system. You can check the oil level without the engine having
run beforehand. If the engine has been ru nning, wait approximately three minutes
before you check the oil. 1.Remove the dipstick (orange).
2. Wipe the dipstick with a clean cloth or
paper towel.
3. Insert the dipstick back all the way into its
hole.
4. Remove the dipstick again, and check the
level. It should be between the upper and
lower marks. Add oil if necessary.1Oil Check
If the oil level is near or below the lower mark, slowly
add oil, being carefu l not to overfill.

uuMaintenance Under the Hood uEngine Coolant
Maintenance
Engine Coolant
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolan t level every time you refuel or you
charge the High Voltage battery. Check the re serve tank first. If it is completely
empty, also check the coolant level in the radiator. Add the engine coolant
accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
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 Hybrid dealer for details.
If Honda antifreeze /coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda anti freeze/coolant as soon as
possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. Th ey may not be compatible
with the coolant or with the engine components.

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.

uuIndicator, Coming On/Blinking uIf the Malfunction Indicator Lamp Comes On or Blinks
Handling the Unexpected
If the Malfunction Indica tor Lamp Comes On or
Blinks
■Reasons for indicator lamp to come on or blink
• Comes on when there is a problem with the engine emissions control
system, or the fuel fill cap is missing, or loose.
• Blinks when engine misfiring is detected.
■What to do when the indicator lamp comes on
Avoid high speeds and immediately ge t your vehicle inspected at an
authorized Honda Clarity Plug-In Hybrid dealer.
■What to do when the indicator lamp blinks
Park the vehicle in a safe place with no flammable items and wait at least
10 minutes or more with the power system stopped until it cools.
■The message appears on when:
An evaporative system leak is detected. This may be caused by the fuel fill cap being
loose or not being installed.
■What to do when the message appears:
1. Stop the power system.
2. Check if the fuel fill cap is fully installed.
u If not, loosen the cap, and then retight en it until it clicks at least once.
3. Drive for several days of normal driving.
u The message should go off.
■When the malfunction indicator lamp comes on
The malfunction indicator lamp comes on if the system continues to detect a leak of
gasoline vapor. If this happens, follow th e procedures described earlier to check the
fuel fill cap.
■Tighten Fuel Cap Message
1 If the Malfunction Indicato r Lamp Comes On or Blinks
NOTICE
If you drive with the malf unction indicator lamp on,
the emissions control system and the engine could be
damaged.
If the malfunction indicator lamp blinks again when
restarting the engine, drive to the nearest an
authorized Honda Clarity Plug- In Hybrid dealer at 31
mph (50 km/h) or less. Have your vehicle inspected.
