Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Honda parts or accessories that may have a similar
effect.
Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is prop erly installed and maintained, and do not
make any modification to your vehicle or its systems that might cause your vehicle
to no longer meet federal, state, prov ince, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1962 connector) installed on this vehicle
is intended to be used with automobile system diagnostic devices or with other
devices that Honda has approved. Use of any other type of device may adversely
affect the vehicle’s electronic systems or allow them to be compromised, possibly
resulting in a system malfunction, drained battery, or other unexpected problems.
Do not modify or attempt to repair your vehicle’s high-voltage hybrid power system
or otherwise modify vehicle electrical systems. Disassembling or modifying electrical
equipment can result in a crash or a fire.
If you ever need to replace your vehicle’s high-voltage battery assembly outside of
warranty coverage, we highly recommend that you only use a genuine Honda high-
voltage battery assembly. Genuine Hond a high-voltage battery assemblies are
designed to work with your vehicle’s hybrid power system and have been designed,
engineered and manufactured to avoid ov ercharging situations. Non-genuine high-
voltage battery assemblies may not have be en similarly designed, engineered and
manufactured, and installation of such assemblies could result in overcharging, fires,
loss of power, or other conditions that may increase the likelihood of a crash or
injury.

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 Fuel
Cell dealer or a 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 tires
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

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.

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 Clar ity Fuel Cell dealer for a
replacement sealant bottle an d proper disposal of an
empty bottle.
