There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may not recognize
him/her as an adult depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or child in convert-ible seat, the system may not recognize him/her as a child. Factors
which may affect this can be the physique or posture.
*5: Never install a rear-facing child restraint system on the front passengerseat. A forward-facing child restraint system should only be installed on
the front passenger seat when it is unavoidable. ( P. 59)
*6: In case the indicator light is not illuminated, consult this manual on how
to install the child restraint system properly. ( P. 58)

WARNING
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant
classification system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
● Make sure the front passenger’s seat belt plate has not been left inserted
into the buckle before someone sits in the front passenger seat.
● Make sure the “AIR BAG OFF” indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the “AIR BAG OFF”
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, and reconnect the seat belt. Reconnect the seat belt extender
after making sure the “AIR BAG ON” indicator light is illuminated. If you
use the seat belt extender while the “AIR BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front passenger will not activate, which
could cause death or serious injury in the event of a collision.
● Do not apply a heavy load to the front passenger seat or equipment (e.g.
seatback pocket).
● Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seat seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.

WARNING
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause the “AIR BAG OFF” indicator light to be illuminated,
which indicates that the SRS airbags for the front passenger will not acti-
vate 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 seatback as upright as possible when the
vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG 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 “AIR BAG OFF” indicator still
remains illuminated, either ask the passenger to move to the rear seat, or
if that is not possible, move the front passenger 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 pas-
senger seat in the proper order. ( P. 59)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
front passenger occupant classification system. In this case, contact your
Toyota dealer immediately.
● Child restraint systems installed on the rear seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.

WARNING
■When installing a child restraint system
Observe the following when installing child restraint system to the front pas-
senger seat if it is unavoidable. The front passenger SRS airbag inflates
with considerable speed and force that if not observed may lead to death or
serious injury to the child.
●Never install a rear-facing child restraint system on the front passenger
seat even if the “AIR BAG OFF” indicator light is illuminated. In the event
of an accident, the force of the rapid inflation of the front passenger airbag
can cause death or serious 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 pas-
senger 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.
If the head restraint interferes with the child restraint system installation
and the head restraint can be removed, remove the head restraint.
● Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the seat, front pillars or roof side rails from
which the SRS side airbags or SRS curtain shield airbags deploy even if
the child is seated in the child restraint system. It is dangerous if the SRS
side and curtain shield airbags inflate, and the impact could cause death
or serious injury to the child.
● 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.
●A forward-facing child restraint system
may be installed on the front passenger
seat only when it is unavoidable. When
installing a forward-facing child restraint
system on the front passenger seat,
move the seat as far back as possible,
and raise the seat to the upper most
position, even if the “AIR BAG OFF”
indicator light is illuminated.

There is an air intake vent beside
the rear left seat for the purpose
of cooling the traction battery. If
the air intake vent is blocked, it
could lead to a reduction in trac-
tion battery output.
■If a warning light comes on, a warn ing message is displayed, or the 12-
volt battery connection is disconnected
The fuel cell system may not be able to restart.
If the “READY” indicator does not come on, even when the start procedure is
repeated, contact your Toyota dealer.
■ 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 nearest Toyota dealer.
■ If “FC System Shutdown due to Hydrogen Leakage Stop Your Vehicle in
a Safe Place and Contact Your Dealer” is displayed on the multi-informa-
tion display
●Hydrogen gas may be leaking.
When hydrogen gas is leaking or some other malfunction is detected:
 P. 9 0
● 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. 371) turns
off before trying to restart. It may not be able to restart if the refueled amount

Hydrogen Gas Characteristics
●Hydrogen gas ignites more easily than gasoline. However, it is lighter than
air and disperses quickly. So even if hydrogen were to leak from the system,
it would quickly dilute until it is no longer flammable.
● As with gasoline and natural gas, hydrogen gas is not dangerous if it is han-
dled properly. Thoroughly read and underst and the characteristics shown in
the table below.

Advice for driving fuel cell vehicles
◆Fuel cell system indicator usage
Maintaining the fuel cell system indicator to Eco area on the
multi-information display can extend your driving range. (P. 1 1 0 )
◆Accelerator pedal/brake pedal operation
Drive the vehicle smoothly. Avoid abrupt acceleration and decelera-
tion.
Mild acceleration and deceleration can help curb wasteful fuel con-
sumption.
◆When braking
Make sure to depress the brake gently and allow for a long stopping
distance. This enables collection of more electrical energy gener-
ated during deceleration.
◆Heavy traffic
Repeated acceleration and deceleration as well as long stops at
traffic lights, will decrease fuel economy. Check traffic reports
ahead of time and avoid traffic jams as much as possible. If caught
in a traffic jam, gently release the brake pedal to allow the vehicle to
move forward slowly while avoiding overuse of the accelerator
pedal to help curb wasteful fuel consumption.
◆Driving with high power output
Similar to an electric vehicle, a fuel cell vehicle uses the most fuel in
high output driving such as driv ing on a steep uphill or at high
speeds. Moderate the vehicle speed and maintain a steady speed.
To maximize fuel economy and ra nge, pay attention to the fol-
lowing:
