Driving
Tire Pressure Monitoring System (TPMS)
Instead of directly measuring the pressure in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated. This will caus e the low tire pressure/TPMS indicator to
come on and a message to appear on the driver information interface.
You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.
Before calibrating the TPMS:
• Set the cold tire pressure in all four tires.
2 Checking Tires P. 468
Make sure:
•The vehicle is at a complete stop.
• The gear position is in
(P.
• The power mode is in ON.
■TPMS Calibration
1Tire Pressure Monitoring System (TPMS)
The system does not monitor the tires when driving
at low speed.
Conditions such as low ambient temperature and
altitude change directly a ffect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on.
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS may not function pr operly if tire type and
size are mixed. Make sure to use the same size and
type of tire. 2 Checking and Maintaining Tires P. 468
The low tire pressure/TPMS indicator may come on
with a delay or may not come on at all when:
•You rapidly accelerate, decelerate, or turn the
steering wheel.
•You drive on snowy or slippery roads.
•Tire chains are used.
The low tire pressure/TPMS indicator may come on
under the following conditions:
•There is a heavier and uneve n load on the tires than
the condition at calibration.
•Tire chains are used.

• The calibration pr ocess finishes
automatically.1 TPMS Calibration
•The calibration process requires approximately 30
minutes of cumulative dr iving at speeds between
30-65 mph (48-105 km/h).
•During this period, if the power system is turned on
and the vehicle is not moved within 45 seconds,
you may notice the low tire pressure/TPMS
indicator comes on briefl y. This is normal and
indicates that the calibr ation process is not yet
complete.
If tire chains are installed, remove them before
calibrating the TPMS.
If the low tire pressure/TPMS indicator comes on even
when the properly inflated specified regular tires are
installed, have your vehicl e checked by an authorized
Honda Clarity Fuel Cell dealer.
We recommend that the tires be replaced with the
same brand, model, and size as the originals. Ask an
authorized Honda Clarity Fuel Cell dealer for details.

Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufa cturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diff erent size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-inf lated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumina tion of the TPMS low ti re pressure telltale.
Your vehicle has also been eq uipped with a TPMS malfunction
indicator to indicate when the sy stem is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

uuWhen Driving uHigh Voltage Battery
Driving
High Voltage Battery
Because electricity generated by the fuel cells and through regenerative braking
recharges the High Voltage battery, the battery does not need to be recharged from
an outside source; however, the High Voltag e battery gradually discharges when the
vehicle is not in use. If allowed to di scharge too much, the battery may become
damaged.
If your vehicle is parked for an extended period of time, during storage for example,
periodically recharge the battery to maintain sufficient charge levels. At least once
every three months, turn on the power sy stem, and keep it on for more than 30
minutes to allow the battery to recharge.
Excessive heat can also damage the battery. On hot, sunny days, try to avoid parking
your vehicle under direct sunlight.
If the High Voltage battery becomes fully discharged or damaged and you are
unable to start the FC system as a result, consult an authorized Honda Clarity Fuel
Cell dealer.

Driving
FC System in Extreme Cold-weather Conditions
The FC system may behave differently on cold days. It may operate a special process
to improve start-up performance and durabi lity. Operation noises, purge process
while parked, etc., differ from usual. However, this is not a malfunction.
On cold days, the power output may be temporarily limited if the vehicle is driven at
high vehicle speeds or accelerated sudd enly before the FC system warm-up is
completed. Operate the vehicle looking ou t for the surrounding traffic until the FC
system reaches full ope rating temperature.
If the exhaust pipe is blocked, the power system may stop. In especially cold
weather, freezing prevention process while parked may not be able to be
performed. Also, the process cannot be carry out if the 12-volt battery terminals are
disconnected; consequently, the FC st ack (fuel cell body) may deteriorate.
On cold days, the hydrogen gas may be consumed faster than usual.
On cold days, when the power system op erates starting/stopping processes or
freezing prevention process while parked, wa ter vapor in the exhaust may appear as
a white mist emitted from the exhaus t pipe. This is not a malfunction.
1FC System in Extreme Cold-weather Conditions
3CAUTION
When the power system operates stopping
process or freezing prevention process
while parked in cold weather, a puddle of
discharged water may form on the ground
and become frozen. Be careful not to slip
on it.

uuWhen Driving uFC System in Extreme Cold-weather Conditions
Driving
On cold days, you may get sprayed with exhaust water if standing behind the vehicle
when:
• The FC system is idling until the READY indicator comes on at power system
start-up.
• The FC system is in the shutdown process after it was stopped before warm-up is
completed.
High Voltage battery is warmed up using the air inside the vehicle. If the air
conditioner is not used or a window is op en, it may take time to complete warm-up.
As a result, the power output may be limited or the READY indicator may take
longer than usual to turn on.
When the power system is tu rned on in extremely cold temperatures between –4°F
and –22°F (–30°C and –20°C), its standby operation noise may become louder than
in normal low temperatures.1 FC System in Extreme Cold-weather Conditions
If the temperature of the fuel cell drops below –4°F
(–20°C), the power system may not start. If the
temperature drops to belo w –22°F (–30°C), the fuel
cells or the High Voltage ba ttery will not operate and,
as a result, the vehicle will not start.
