Fuel cell system
WARNING
●The hydrogen tanks, fuel cell
stack, hydrogen pipelines, and
connecting components are
filled with hydrogen gas. Do not
remove or disassemble these
parts. Doing so can cause a
hydrogen gas leak, resulting in
fire or explosion of the vehicle,
which may result in death or
serious injury.
■When hydrogen gas leak or
other malfunctio n is detected
●If a large amount of hydrogen
gas leaking is noticed, turn off
the power switch, exit the vehi-
cle, and stay far away from it.
Display warning signs and keep
sources of fire away from the
vehicle. If possible, get assis-
tance. When the above is done,
immediately contact your Toyota
dealer.
●If you notice gas leaking or any
other malfunction, immediately
stop the vehicle in a safe and
well-ventilated place, exit the
vehicle, and stay far away from
it.
●If a warning message is dis-
played in the multi-information
display, immediately stop the
vehicle in a safe, well-ventilated
outdoor place.
■Tailpipe
●Do not directly touch the water
or steam coming out of the tail-
pipe. Doing so may cause low-
temperature burns.
●The fuel cell vehicle generates
water during power generation.
The generated water dis-
charged from the tailpipe is not
suitable for drinking. Never
drink the water coming out of
the tailpipe.
●You may notice a strange odor
from the tailpipe for a while after
the purchase of a new vehicle
or after an extended period of
non-use, but this is not a mal-
function. Also, the odor is harm-
less but it may be unpleasant,
so do not breathe in the
exhaust.
■High-voltage and high-tem-
perature precautions
This vehicle is equipped with a
high-voltage system. Follow the
instructions below as high-volt-
ages can cause severe burns and
electric shock that may result in
death or serious injury.
●Never touch, disassemble,
remove, or replace the high-
voltage parts, cables (orange),
or connectors.
●The components inside the fuel
cell unit compartment will
become hot during operation.
Be careful of both the high-volt-
age and high-temperature, and
always obey the warning labels
on the vehicle.
●Never touch the service plug
that is installed on the traction
battery. The service plug is used
to block high-voltages coming
from the traction battery during
maintenance or repair at your
Toyota dealer.
