■Pop Up Hood precautions
●Before scrapping your vehicle,
make sure to contact your Toyota
dealer.
●The Pop Up Hood system cannot
be reused once it has operated.
Have it replaced by your Toyota
dealer.
■PCS-linked Pop Up Hood opera-
tion control
If the PCS (Pre-Collision System)
determines that the possibility of a
collision with a pedestrian or bicy-
clist is high, the Pop Up Hood will be
prepared to operate.
■Pop Up Hood operational condi-
tions
The Pop Up Hood will operate when
the vehicle detect s an impact such
as the following:
●The front bumper detects a frontal
impact equivalent to or greater
than that of a pedestrian while the
vehicle being driven within the
operational speed range of
approximately 16 to 34 mph (25 to
55 km/h). (The system is operated
by an impact of threshold level or
greater, even in the case of a
minor collision that may not leave
a trace on the front bumper. Also,
depending on the impact condi-
tions or vehicle speed, the system
may operate by a collision with a
light or small object or a small ani-
mal.)
●In other situations, such as the fol-
lowing the system may operate
when an impact is applied to the
lower part of the vehicle or front
bumper:
• Colliding with a curb
• Falling into a deep hole
• Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding
object or fa lling object
■Conditions under which the
Pop Up Hood may not operate
properly
●If a pedestrian c ollides with the
right or left corner of the front
bumper or the side of the vehicle.
As such impacts may be difficult to
detect, the system may not oper-
ate.
●If the vehicle speed is not
detected correctly , such as if the
vehicle is sliding sideways, the
system may not operate properly.
■Conditions under which the
Pop Up Hood will not operate
The Pop Up Hood will not operate in
the following situations:
●Colliding with a lying person
●A frontal impac t applied to the
front bumper while driving at
speeds outside of the operational
speed range
●A side impact or rear impact
●A vehicle rollover (In some acci-
dent situations, the Pop Up Hood
may operate.)
WARNING
■When the Pop Up Hood is
operated
●Do not pull the hood lock
release lever. Doing so after the
Pop Up Hood has operated will
further raise the hood and may
cause an injury. Do not drive
with the hood raised, as doing
so may block the driver’s vision,
possibly causing an accident.
●Do not forcibly push down the
hood. As the popped up hood
cannot be lowered by hand,
doing so may deform the hood
or cause an injury.

tions
Observe the following precautions
regarding the front passenger
occupant classification system.

WARNING
●Make sure the “AIRBAG OFF”
indicator light is not illuminated
when using the seat belt
extender for the front passenger
seat. If the “AIRBAG OFF” indi-
cator light is illuminated, discon-
nect the extender tongue from
the seat belt buckle, and recon-
nect the seat belt. Reconnect
the seat belt extender after
making sure the “AIRBAG ON”
indicator light is illuminated. If
you use the seat belt extender
while the “AIRBAG OFF” indica-
tor light is illum inated, the SRS
airbags for the front passenger
will not activate, which could
cause death or ser ious injury in
the event of a collision.
●Do not apply a heavy load to the
front passenger seat or equip-
ment (e.g. seatback pocket).
●Do not put weight on the front
passenger seat by putting your
hands or feet on the front pas-
senger seat seatback from the
rear passenger seat.
●Do not let a rea r passenger lift
the front passenger seat with
their feet or press on the seat-
back with their legs.
●Do not put objects under the
front passenger seat.
●Do not recline t he front passen-
ger seatback so far that it
touches a rear seat. This may
cause the “AIRBAG OFF” indi-
cator light to be illuminated,
which indicates that the SRS
airbags for the front passenger
will not activate in the event of a
severe accident. If the seatback
touches the rear seat, return the
seatback to a position where it
does not touch the rear seat.
Keep the front passenger seat-
back as upright as possible
when the vehicle is moving.
Reclining the seatback exces-
sively may lessen the effective-
ness of the seat belt system.
●If an adult sits i n the front pas-
senger seat, the “AIRBAG ON”
indicator light i s illuminated. If
the “AIRBAG OFF” indicator is
illuminated, ask the passenger
to sit up straight, well back in
the seat, feet on the floor, and
with the seat belt worn correctly.
If the “AIRBAG OFF” indicator
still remains illumi nated, either
ask the passenger to move to
the rear seat, or if that is not
possible, move the front pas-
senger seat fully rearward.
●When it is unavoidable to install
a forward-facing child restraint
system on the front passenger
seat, install the child restraint
system on the front passenger
seat in the proper order.
(  P. 5 4 )
●Do not modify or remove the
front seats.
●Do not kick the front passenger
seat or subject it to severe
impact. Otherwise, the SRS
warning light m ay come on to
indicate a malfu nction of the
front passenger occupant clas-
sification system. In this case,
contact your Toyota dealer
immediately.

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
