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 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
able to repair the puncture using the kit.
When the puncture is:Kit Use

Handling the Unexpected
Emergency Power System Off
The POWER button may be used to turn the power system off due to an emergency
situation even while driving. If you must tu rn the power system off, do either of the
following operations:
• Press and hold the POWER button for about two seconds.
• Firmly press the POWER button three times.
The steering wheel will not lock. However, because turning off the power system
disables the power assist the power syst em provides to the steering and braking
systems, it will require significantly more physical effort and time to steer and slow
the vehicle. Use both feet on the brake pe dal to slow down the vehicle and stop
immediately in a safe place.
The gear position auto matically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.
1 Emergency Power System Off
Do not press the button while driving unless it is
absolutely necessary for the power system to be
turned off.
