Notes on fueling

●

Fueling will not be possible if the

pressure inside the vehicle’s

hydrogen tanks is higher than the

supply pressure of the hydrogen

station. If the hydrogen tanks are

more than half full, the vehicle will

be unable to fuel at a H35 dis-

penser. A hydrogen station with a

H70 dispenser (supply pressure of
10150 psi) [70 MPa, 714 kgf/cm

700 bar] is necessary to com-

pletely fill hydrogen tanks.

●

If the fueling cannot be completed

due to trouble with the station

equipment, call the number indi-

cated on the equipment.

Opening the fuel door



Fuel with compressed
hydrogen gas only at hydro-
gen stations.



Fuel at hydrogen stations
conforming with the Society
of Automotive Engineers
(SAE) J2601 fueling proto-
col or laws that may super-
sede such SAE protocols.

Before filling

WARNING

■

When filling

Observe the following precautions

while fueling the vehicle. Failure

to do so may result in death or

serious injury.

204

5-4. Refueling

WARNING

●

Turn the power switch off before

fueling.

●

Ensure the hydrogen gas noz-

zle is locked onto the vehicle

receptacle before filling. This

can be done by pulling on the

hydrogen gas nozzle to check

that it cannot be pulled off. Fail-

ure to do so may result in injury

or damage to the hydrogen gas

nozzle or vehicle.

●

Do not smoke while fueling.

●

Because the fuel is cold, the

hydrogen gas nozzle and vehi-

cle receptacle surface will

become cold, and frost may

develop. After fueling is com-

pleted, remove the hydrogen

gas nozzle by the plastic handle

only. Do not touch any other

parts of the hydrogen gas noz-

zle or vehicle receptacle with

bare hands immediately after

fueling, as frostbite may occur.

●

Be sure to use hydrogen gas

nozzles at 350 bar/700 bar for

passenger vehicles.

Do not use hydrogen gas noz-

zles designed for commercial

vehicles. Check the instructions

at hydrogen station or ask the

station operator for assistance.

●

Only fuel the vehicle at hydro-

gen stations designed for pas-

senger vehicles. Do not fuel the

vehicle at hydrogen stations

designed for forklifts, buses, or

trucks. Ask the station operator

for assistance.

NOTICE

■

When filling

●

Fuel only with compressed

hydrogen gas at stations com-

pliant with the Society of Auto-

motive Engineers (SAE) J2601

fueling protocol or laws that may

supersede such SAE protocols.

If improper fuels are used, the

fuel cell stack will be damaged.

●

Do not swing or drop the hydro-

gen gas nozzle, or subject it to a

large amount of force. Doing so

may cause damage.

●

If the hydrogen gas nozzle can-

not be removed after fueling, it

may be frozen to the vehicle

receptacle. Wait for the hydro-

gen gas nozzle to thaw before

attempting to remove. Do not

pull or rotate the hydrogen gas

nozzle forcibly. Failure to follow

these precautions may cause

damage.

●

Be sure to replace the cap after

filling. If foreign material gets in

the vehicle receptacle, it may

cause damage.

●

Do not put anything sharp, such

as a screwdriver, blade, or any

foreign object into the opening

of the vehicle receptacle. If the

vehicle receptacle is damaged,

hydrogen gas may leak during

fueling.

●

If you notice anything unusual

about the vehicle receptacle,

please notify your Toyota

dealer.

●

If you notice anything unusual

with the hydrogen dispenser or

hydrogen gas nozzle, please

notify the hydrogen station

operator. Contact information is

usually displayed on the dis-

penser.
