NOTE: EDR data are recorded
by your vehicle only if a non-triv-
ial crash situation occurs; no
data are recorded by the EDR
under normal driving conditions
and no personal data (e.g.,
name, gender, age, and crash
location) are recorded. How-
ever, other parties, such as law
enforcement, could combine the
EDR data with the type of per-
sonally identifying data rou-
tinely acquired during a crash
investigation.
To read data recorded by an
EDR, special equipment is
required, and access to the
vehicle or the EDR is needed. In
addition to the vehicle manufac-
turer, other parties, such as law
enforcement, that have the spe-
cial equipment, can read the
information if they have access
to the vehicle or the EDR.
Disclosure of the EDR data
Toyota will not disclose the data
recorded in an EDR to a third party
except when:
• An agreement from the vehicle’s
owner (or the less ee for a leased
vehicle) is obtained
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
 However, if necessary, Toy-
ota may:
• Use the data for research on
vehicle safety performance • Disclose the data to a third party
for research pur poses without
disclosing information about the
specific vehicle or vehicle owner
The SRS airbag, seat belt pre-
tensioner devices and Pop Up
Hood system in your Toyota
contain explosive chemicals. If
the vehicle is scrapped with the
airbags, seat belt pretensioners
and Pop Up Hood micro gas
generators left as they are, this
may cause an accident such as
fire. Be sure to have the sys-
tems of the SRS airbag, seat
belt pretensioner and Pop Up
Hood micro gas generators
removed and disposed of by a
qualified service shop or by your
Toyota dealer before you scrap
your vehicle.

■Fuel types
 P.497
■Notes on fueling
●Fueling will not be possible if the
pressure inside the vehicle’s
hydrogen tanks is higher than the
supply pressure of the hydrogen
station. If the hydrogen tanks are
more than half full, the vehicle will
be unable to fuel at a H35 dis-
penser. A hydrogen station with a
H70 dispenser (supply pressure of
10150 psi) [70 MPa, 714 kgf/cm
2,
700 bar] is necessary to com-
pletely fill hydrogen tanks.
●If the fueling cannot be completed
due to trouble with the station
equipment, call the number indi-
cated on the equipment.
Opening the fuel door
Fuel with compressed
hydrogen gas only at hydro-
gen stations.
Fuel at hydrogen stations
conforming with the Society
of Automotive Engineers
(SAE) J2601 fueling proto-
col or laws that may super-
sede such SAE protocols.

tery.

4888-2. Steps to take in an emergency
Owners Manual_USA_M62064_en
■When replacing the 12-volt bat-
tery
●Use a Central Degassing type 12-
volt battery (European Regula-
tions).
●Use a 12-volt battery with the
same case size as the previous
12-volt battery and an equivalent
20 hour rate capacity (20HR) or
greater.
• If the sizes differ, the 12-volt bat- tery cannot be properly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and the fuel cell system may not
be able to start.
●Use a 12-volt battery with a han-
dle. If a 12-volt b attery without a
handle is used, removal is more
difficult.
●After replacing, firmly attach the
following items to the exhaust hole
of the 12-volt battery.
• Use the exhaust hose that was
attached to the 12-volt battery
before replacing an d confirm that
it is firmly connected to the hole
section of t he vehicle.
• Use the exhaust hole plug included with the 12-volt battery
replaced or the one installed on
the 12-volt battery prior to the

WARNING
■When removing the 12-volt
battery terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, leading to a fire
in addition to ele ctrical shocks
and death or serious injury.
■Avoiding 12-volt battery fires
or explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the 12-volt battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighter s or allow open
flame near the 1 2-volt battery.
