Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation includes crash sever-
ity and occupant information. As the airbags deploy, a chemical
reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the front seats,
parts of the front and rear pillars,
and roof side rails, may be hot for
several minutes. T he airbag itself
may also be hot.
●The windshield may crack.
●The fuel cell system will be
stopped and hydr ogen supply will
be stopped fro m the hydrogen
tank valves. ( P. 8 9 )
●All of the doors will be unlocked.
( P.128)
●The brakes and st op lights will be
controlled automatically. ( P.323)
●The interior lights will turn on auto-
matically. ( P.357)
●The emergency flashers will turn
on automatically. ( P.446)
●For Safety Connect subscribers, if any of the following situations
occur, the system is designed to
send an emergency call to the
response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. (
P. 6 5 )
• An SRS airbag is deployed.
• A seat belt pretensioner is acti- vated.
• The vehicle is involved in a severe rear-end collision.
■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy
in the event of an impact that
exceeds the set threshold level
(the level of forc e corresponding
to an approximately 12 - 18 mph
[20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform).
However, this threshold velocity will
be considerably higher in the follow-
ing situations:

Pop Up Hood
In the event of a frontal col-
lision with a body, such as a
pedestrian, the Pop Up
Hood system raises the
hood to reduce the possibil-
ity of a serious impact to the
pedestrian’s head area by
adding clearance to the fuel
cell unit compartment.
When the sensors located
at the back of the front
bumper detect a frontal
impact with a body, such as
a pedestrian, which meets
or exceeds the threshold
level while the vehicle is
being driven within the
operational speed range,
the system operates.

WARNING
●If the Pop Up Hood has oper-
ated, have it replaced by your
Toyota dealer. If the Pop Up
Hood has operated, stop the
vehicle in a safe place and con-
tact your Toyota dealer.
●Do not touch the lifters immedi-
ately after the Pop Up Hood has
operated, as the lifters may be
hot and burn you.
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood
before driving, as the system
may not operate properly if the
hood is not fully closed.
●Make sure that all 4 tires are of
the specified size and inflated to
the specified tire pressure. If
tires of a different size are used,
the system may not operate
properly.
●If something has hit the area
around the front bumper, the
sensors may be damaged even
if the Pop Up Hood has not
operated. Have the vehicle
inspected by your Toyota
dealer.
●Do not remove or repair the
parts or wiring of the Pop Up
Hood, as doing so may cause
accidental operation or prevent
the system from operating prop-
erly. If repair or replacement is
necessary, contact your Toyota
dealer.
●Do not remove such compo-
nents as the front bumper, hood
or suspension, or replace them
with non-genuine parts, as
doing so may prevent the sys-
tem from operating properly.
●Do not install anything to the
front bumper or hood, as doing
so may prevent the sensors
from detecting an impact cor-
rectly and prevent the system
from operating properly.
●Do not close the hood with force
or apply load to the lifters, as
doing so may damage the lifters
and prevent the system from
operating properly.
●Do not modify the suspension,
as changes made to the vehicle
height may prevent the system
from operating properly.

■Basic concepts of hydrogen
safety
●Prevent leakage
The pipe joints o f the hydrogen
pipelines are designed to prevent
leaks.
The joints are checked for gas leak-
age at every official vehicle inspec-
tion.
●Detect to stop leakage
• The vehicle is equipped with
hydrogen detectors. If the hydro-
gen detectors detect a leak, the
hydrogen tank valves automati-
cally close to prevent more hydro-
gen from escaping.
• The vehicle is equipped with a col- lision sensor. If the collision sen-
sor detects a collision, the
hydrogen tank valves automati-
cally close to prevent hydrogen
gas from leaking from any dam- aged components.
●Disperse the leaked hydrogen gas
The hydrogen tanks and pipelines
are located outside of the passenger
compartment, so any leaked gas will
disperse into the atmosphere by
design.
●Eliminate sources of fire
No source of fire is located near the
hydrogen pipelines by design.

Before driving
doors detecting the electronic key
can be used to unl ock the vehicle.
●Even if the electronic key is not
inside the vehicle, it may be possi-
ble to start the fuel cell system if
the electronic key is near the win-
dow.
●The doors may unlock or lock if a
large amount of water splashes on
the door handle, such as in the
rain or in a car wash, when the
electronic key is within the effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the
doors are not opened and closed.)
●If the wireless remote control is
used to lock the doors when the
electronic key is near the vehicle,
there is a possib ility that the door
may not be unlocke d by the entry
function. (Use the wireless remote
control to unloc k the doors.)
●Touching the door lock sensor
while wearing gloves may delay or
prevent lock operation.
●When the lock op eration is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recogniti on signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective ran ge, the door may
lock and unlock repeatedly. In this
case, follow the fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca- tion 6 ft. (2 m) or more away from
the vehicle. (Take care to ensure
that the key is not stolen.)
• Set the electronic key to battery- saving mode to disable the smart
key system. ( P.137)
●If the electronic key is inside the
vehicle and a door handle
becomes wet during a car wash, a
message may be shown on the
multi-informatio n display and a buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it comes into contact
with ice, snow, m
ud, etc. Clean
the lock sensor and attempt to
operate it again.
●A sudden approach to the effec-
tive range or door handle may pre-
vent the doors from being
unlocked. In this case, return the
door handle to the original position
and check that t he doors unlock
before pulling the door handle
again.
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.
■When the vehicle is not driven
for extended periods
●To prevent theft of the vehicle, do
not leave the electronic key within
6 ft. (2 m) of the vehicle.
●The smart key system can be
deactivated in advance.
●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. ( P.137)
■To operate the system properly
●Make sure to carry the electronic
key when operating the system.
Do not get the electronic key too
close to the vehicle when operat-
ing the system from the outside of
the vehicle.
Depending on the position and hold-
ing condition of the electronic key,
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off
accidentally, or the door lock pre-
vention function m ay not operate.)
●Do not leave the electronic key
inside the trunk.
The key confinement prevention
function may not operate, depend-
