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
Opening the Hood
1. Park the vehicle on a level surface, and set
the parking brake.
2. Pull the hood release handle under the
driver’s side lower corner of the dashboard.
u The hood will pop up slightly.
3. Push the hood latch lever (located under
the front edge of the hood to the center) to
the side and raise the hood. Once you have
raised the hood slightly, you can release the
lever.
4. Remove the support rod from the clamp
using the grip. Mount the support rod in
the hood.
When closing, remove the support rod, and
stow it in the clamp, then gently lower the
hood. Remove your hand at a height of
approximately 12 inches (30 cm) and let the
hood close.1 Opening the Hood
NOTICE
Do not open the hood when the wiper arms are
raised: The hood will strike the wipers, resulting in
possible damage to the hood and/or the wipers.
NOTICE
Do not press the engine cover forcibly. This may
damage the engine cover and component parts.
When closing the hood, check that the hood is
securely latched.
If the hood latch lever moves stiffly, or if you can
open the hood without lifti ng the lever, the latch
mechanism should be cl eaned and lubricated.

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.

Maintenance
12-Volt Battery
Checking the 12-Volt Battery
Check the battery condition monthly. Look at
the test indicator window and check the
terminals for corrosion.
The battery condition is monitored by the
sensor on the negative terminal. If there is a
problem with the sensor, the warning
message on the driver information interface
will let you know. Have your vehicle checked
by an authorized Honda Clarity Plug-In Hybrid
dealer.
If your vehicle’s battery is disconnected or goes dead:
• The audio system is disabled.
2 Reactivating the audio system P. 206
•The clock resets.
2 Clock P. 136
•The vehicle cannot be charged. After reconnecting the batte ry, turn the power
system on, then turn it off.
Confirm that charging is possible.
2 Turning on the Power P. 378

WARNING: Battery post, terminals,
and related accessories contain lead
and lead compounds.
Wash your hands after handling.
The test indicator’s color in formation is on the battery.
When you find corrosion, cl ean the battery terminals
by applying a baking powder and water solution.
Clean the terminals with a damp towel. Cloth/towel
dry the battery. Coat the terminals with grease to
help prevent future corrosion.
3WARNING
The battery gives off explosive hydrogen
gas during normal operation.
A spark or flame can cause the battery to
explode with enough force to kill or
seriously hurt you.
When conducting any battery
maintenance, wear prot ective clothing and
a face shield, or have a skilled technician do
it.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely 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

7. Press the inflator switch to turn on the
compressor.
u The compressor starts injecting sealant
and air into the tire.
u When the sealant injection is complete,
continue to add air.
8. After the air pressure reaches 36 psi (250
kPa), turn off the kit.
u To check the pressure, occasionally turn
off the compressor, and read the
gauge.
9. Unplug the power plug from the accessory
power socket.
10. Unscrew the sealant/ai r hose from the tire
valve stem. Reinstall the valve cap.
11. Press the pressure relief button until the
gauge returns to 0 psi (0 kPa).
ON
OFF
Pressure Gauge1Injecting Sealant and Air
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begin to rise again as the
tire is inflated with air. This is normal. To accurately
measure the air pressure usin g the gauge, turn the air
compressor off only after the sealant injection is
complete.
If the required air pressure is not reached within 10
minutes, the tire may be too severely damaged for
the kit to provide the necessa ry seal, and your vehicle
will need to be towed.
See an authorized Honda Clarity Plug-In Hybrid
dealer for a replacement sealant bottle and proper
disposal of an empty bottle.

2 Inflating an Under-inflated Tire P. 535
6.If the air pressure is
• Less than 25 psi (175 kPa):
Do not add air or continue driving. The

•36 psi (250 kPa) or more:
Continue driving for another 10 minutes
or until you reach the nearest service
station, whichever is sooner. Do not
exceed 50 mph (80 km/h). If you have not
reached a service station after 10 minutes,
stop in a safe place and check the tire
pressure.
u If the air pressure does not go down
after the 10 minute driving, you do not
need to check the pressure any more.
