WARNING
■When filling
Observe the following precautions while fueling the vehicle.
Failure to do so may result in death or serious injury.
● Turn the power switch off before fueling.
● Ensure the hydrogen gas nozzle 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.
Failure 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 vehicle 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 nozzle or vehicle receptacle
with bare hands immediately after fueling, as frostbite may occur.
NOTICE
■ When filling
● Fuel only with compressed hydrogen gas at stations compliant with the
Society of Automotive 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 hydrogen gas nozzle, or subject it to a large
amount of force. Doing so may cause damage.
● If the hydrogen gas nozzle cannot be removed after fueling, it may be fro-
zen to the vehicle receptacle. Wait for the hydrogen 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 mouth 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 informa-
tion is usually displayed on the dispenser.
