For safety and security
install the child restraint system.
 Move the front seat fully rear-
ward.
 Adjust the seatback angle to
the most upright position.
When installing a forward-facing
child seat, if there is a gap between
the child seat and the seatback,
adjust the seatback angle until
good contact is achieved.
If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
Otherwise, put the head
restraint in the upper most
position.
WARNING
■When using a child restraint
system
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Never install a rear-facing child
restraint system on the front
passenger seat even if the “AIR-
BAG OFF” indicator light is illu-
minated. In the event of an
accident, the force of the rapid
inflation of the front passenger
airbag can cause death or seri-
ous injury to the child if the rear-
facing child restraint system is
installed on the front passenger
seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. A child
restraint system that requires a
top tether strap should not be
used in the front passenger seat
since there is no top tether strap
anchor for the front passenger
seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. When install-
ing a forward-facing child
restraint system on the front
passenger seat, adjust the seat-
back angle to the most upright
position, move the seat to the
rearmost position, and raise the
seat to the upper most position,
even if the “AIRBAG OFF” indi-
cator light is illuminated.

■If “Hydrogen Leakage Detected
Visit Your Dealer” is displayed
on the multi-information display
A small amount of hydrogen gas
may be leaking. Have the vehicle
inspected immediately at the near-
est Toyota dealer.
■If “FCV System Shutdown Due
to Hydrogen Leakage Stop in a
Safe Place See Owner’s Man-
ual” is displayed on the multi-
information display
●Hydrogen gas may be leaking.
When hydrogen gas is leaking or
some other malfunction is
detected: P. 8 7
●The air conditioning system will
shut off automatically.
■Running out of fuel
When the vehicle has run out of fuel
and the fuel cell system cannot be
started, refuel the vehicle until the
low fuel level warning light ( P.460)
turns off before try ing to restart. It
may not be able to restart if the refu-
eled amount is too low.
■Fuel cell stack
●Depending on the usage environ-
ment, the fuel ce ll power output
may decline over the life of the
vehicle. However, this will have
almost no effect on driving perfor-
mance.
●In the following situations, the fuel
cell power output may decline
faster than normal driving:
• Extended use in areas with high
amounts of dust
• Extended use in areas with high levels of sulfur (such as volcanoes
or hot springs).
• Extended use in areas with high concentrations o f the following
substances:
-Organic solvents, such as paint and
thinner
-Amine-related materials such as
ammonia
-Chlorinated substances such as
salt air and snow-melting agent
• Salt water gets into the air cleaner filter
It is recommended to replace the
air cleaner filter and clean the sur-
rounding components. Have the
vehicle inspected at your Toyota
dealer
• The number of times the fuel cell system is started and stopped is
excessively high
• Extended use in freezing tem- peratures
• Fill fuel with impurities which do not follow ISO-14687
■Hydrogen tanks
●The hydrogen tanks are the high-
pressure storage containers that
are filled with co mpressed hydro-
gen gas. The vehicle can be refu-
eled at hydrogen stations.
●The hydrogen tanks have an expi-
ration date. Vehicles with expired
hydrogen tanks must not be
driven or refueled until the hydro-
gen tanks are replaced. The expi-
ration date is written on the inside
of the fuel door. Consult your Toy-
ota dealer.
●Consult your Toyota dealer if the

842-1. Fuel cell electric vehicle
Owners Manual_USA_M62064_enhydrogen tanks or valves need to
be disposed.
■Fuel cell stack coolant
●Fuel cell stack coolant uses a spe-
cifically-designed fluid with high
electrical insulation properties, in
order to safely cool the high-volt-
age fuel cell stack.
●Never add water or other coolants
to the fuel cell st
ack cooling sys-
tem, as they will cause permanent
damage.
●Consult your Toyota dealer for
replenishing or changing the fuel
cell stack coolant.
■Ion filter
●An ion filter is inst alled in the cool-
ant lines for the fuel cell stack, in
order to maintain the normal insu-
lation properties of the coolant.
●It is necessary to periodically
change the ion filter. ( P.466)
Contact your Toyota dealer for this
periodic maintenance.
■Tailpipe
●When the power switch is turned
off and the fuel cell system is
stopped ( P.182) after driving,
exhaust water is discharged. Be
careful when standing behind the
vehicle to avoid dripping or spray-
ing.
●It is possible to manually purge
the exhaust. Thi s may be desir-
able, for instance, before parking
in a garage. This is done by press-
ing the H
2O switch. ( P.196)
●On cold days, water vapor in the
exhaust may appe ar as a white
mist emitted from the tailpipe. This
is not a malfunction. A white mist
may be emitted from the vehicle
side depending on the wind direc-
tion. If it is a concern, consult with
a Toyota dealer.
●If the tailpipe is blocked, the fuel
cell system will stop.
●In the following state when cold, a white mist may be emitted. Water
vapor is being emitted as a sys-
tem protection and it is not a mal-
function.
• If several minutes have passed after opening the fuel lid, such as
refueling.
• Several hours have passed after the power switch was turned off.
■Hydrogen detectors
When the power switch is turned to
ON, the hydrogen detectors are
activated.
■Power output restriction
When the power output is restricted,
the vehicle may fa il to accelerate or
even decelerate, even though the
accelerator pedal is depressed. If a
safe driving speed cannot be main-
tained, stop the ve hicle in a safe
place away from the traffic. This
may be caused by the following con-
ditions:
●The coolant temperature may be
too high. This can be caused by
driving conditions such as
repeated sudden acceleration and
deceleration, continuous driving
on an incline, continuous driving
at high altitudes with a high load,
etc. In such situations, “FCV sys-
tem overheated Output power
reduced” is displayed on the multi-
information display, and the power
output is restricted. Once the cool-
ant returns to normal temperature,
the power output will retu rn to nor-
mal. ( P.464)
●The remaining fuel may be low.
After the low fuel level warning
light comes on, the output power
will be gradually restricted in order
to extend the possible driving dis-
tance. Once getting to this point,
the remaining driving distance
possible is short. Immediately refill
the vehicle with hydrogen.
●On cold days, the low fuel level
warning light comes on faster than
usual and the output power is
restricted.

Fuel cell system
■Electromagnetic waves (EMF)
●High-voltage parts and cables in
fuel cell electric vehicles have an
electromagnetic shielding configu-
ration, and therefore emit approxi-
mately the same amount of
electromagnetic waves as con-
ventional gasoli ne-powered vehi-
cles or home electronic
appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Starting the fuel cell system in
an extremely col d environment
When the tracti on battery is extremely cold (below approxi-
mately -22˚F [-30˚C]) under the
influence of outsi
de temperature, it
may not be possible to start the fuel
cell system. In this case, try to start
the fuel cell system again after the
temperature of the traction battery
increases due to the outside tem-
perature increase etc.
■Traction battery
The traction battery has a limited
service life. The lifespan of the trac-
tion battery can change according to
driving style and driving conditions.
■Hydrogen Gas Characteristics
●Hydrogen gas ignites more easily than gasoline, however it is l ight than air
and disperses quickly. The hydrogen system and tank sufficientl y serve as
a counter-measure to prevent gas leaks. However, if by chance there is a
gas leak, the hydrogen gas is rapidly diluted until it is no lo nger flammable.
●As with gasoline and natural gas, hydrogen gas is not dangerous if it is
handled properly. Thoroughly rea d and understand the characteristics
shown in the table below.
