601-2. Child safety
Owners Manual_USA_M62064_en
■Child restraint LATCH
anchors
LATCH anchors are provided for
the outboard rear seat. (Buttons
displaying the location of the
anchors are attached to the
seats.)
■When installing in the rear
outboard seats
Install the child restraint system
WARNING
●Shake the child restraint system
left and right, and forward and
backward to ensure that it has
been securely installed.
●When a booster seat is
installed, always ensure that the
shoulder belt is positioned
across the center of the child’s
shoulder. The belt should be
kept away from the child’s neck,
but not so that it could fall off the
child’s shoulder.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.
●When securing some types of
child restraint s ystems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting seat belt effective-
ness. Be sure your seat belt fits
snugly across your shoulder
and low on your hips. If it does
not, or if it interferes with the
child restraint, move to a differ-
ent position. Failure to do so
may result in death or serious
injury.
●When installing a child restraint
system in the rear center seat,
adjust both seat cushions to the
same position and align both
seatbacks at the same angle.
Otherwise, the child restraint
system cannot be securely
restrained and t his may cause
death or serious injuries in the
event of sudden braking, sud-
den swerving or an accident.
●If the seat is adjusted, reconfirm
the security of the child restraint
system.
■When installing a booster
seat
To prevent the belt from going into
ALR lock mode, do not fully
extend the shoulder belt. ALR
mode causes the belt to tighten
only. This could cause injury or
discomfort to the child. ( P. 3 1 )
■Do not use a seat belt
extender
If a seat belt extender is used
when installing a child restraint
system, the seat belt will not
securely hold the child restraint
system, which could cause death
or serious injury to the child or
other passengers in the event of
sudden braking, sudden swerv-
ing or an accident.

Fuel cell system
Fuel cell electric vehicles do not
have engine sounds like gaso-
line vehicles. Therefore, a
sound that changes in accor-
dance with the driving speed,
will be played in order to warn
people nearby of the vehicle’s
approach. The sound will stop
when the vehicle speed
exceeds approximately 23 mph
(37 km/h).
■How to hear the warning
In the following ca ses, the acoustic
vehicle alerting system may be diffi-
cult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the acoustic vehicle alerting
system is installed on the front of the
vehicle, it may be m ore difficult to
hear from the rear of the vehicle
compared to the front.
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “MULTIME-
DIA OWNER’S MANUAL”.
■Predictive deceleration sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the refer-
ence operation range of
the ECO Accelerator Guid-
ance ( P.108) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.

■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.
