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 recep tacle
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 r eceptacle
surface will become cold, and frost may develop. After fueling is com-
pleted, remove the hydrogen gas nozzle by the plastic handle on ly. Do not
touch any other parts of the hydrogen gas nozzle or vehicle rec eptacle
with bare hands immediately after fueling, as frostbite may occ ur.
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 g ets 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, pl ease notify
your Toyota dealer.
● If you notice anything unusual with the hydrogen dispenser or h ydrogen
gas nozzle, please notify the hydrogen station operator. Contac t informa-
tion is usually displayed on the dispenser.

Pulling the lever toward you
cancels the speed control.
The speed setting is also canceled
when the brake pedal is
depressed.
Pushing the lever up resumes
the speed control and returns
vehicle speed to the set speed.
However, when a vehicle ahead is not detected in vehicle-to-veh icle dis-
tance control mode, cruise control does not resume when the act ual vehi-
cle speed is approximately 25 mph (40 km/h) or less. Also, when the
vehicle is in constant speed control mode and the actual vehicl e speed is
approximately 25 mph (40 km/h) or less, cruise control does not resume as
the set speed is cleared.
When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the
cruise control is not possible, the
display will flash and the buzzer
will sound to alert the driver. An
example of this would be if
another driver cuts in front of you
while you are foll owing a vehicle.
Depress the brake pedal to ensure an appropriate vehicle-to-veh icle
distance.
■Warnings may not occur when
In the following instances, there is a possibility that the warnings will
not occur:
● When the speed of the preceding vehicle matches or exceeds
your vehicle speed
● When the preceding vehicle is traveling at an extremely slow sp eed
● Immediately after the cruise control speed was set
● When depressing the accelerator pedal
