WARNING
■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Firmly attach the top tether strap and make sure that the belt is not twisted.
● Do not attach the top tether strap to anything other than the anchor
bracket.
● Shake the child restraint system left and right, and forward and backward
to ensure that it has been securely installed.
● Follow all installation instructions provided by the child rest raint system
manufacturer.
● When installing the child restraint system with the head restra int being
raised, after the head restraint has been raised and then the anchor
bracket has been fixed, do not lower the head restraint.
NOTICE
■ Anchor brackets (for top tether strap)
When not in use, make certain to close the lid. If it remains o pen, the lid
may be damaged.

Immobilizer system
The indicator flashes after the
power switch has been turned off
to indicate that the system is oper-
ating.
The indicator stops flashing after
the power switch has been turned
to ACCESSORY or ON mode to
indicate that the system has been
canceled.
The vehicle’s keys have built-in transponder chips that prevent
the fuel cell system from starting if a key has not been previ-
ously registered in the veh icle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehi-
cle.
This system is designed to help prevent vehicle theft but does
not guarantee absolute security against all vehicle thefts.

Fuel cell vehicle characteristics
This diagram is for illustrative purposes only and may differ from the
actual vehicle.
Fuel cell vehicles efficiently use electricity, which is genera ted
by a chemical reaction between hydrogen and oxygen in a fuel
cell stack, and electricity charged in a traction battery to dr ive
the electric motor (traction motor).
The fuel is H
2 (compressed hydrogen gas), so the exhaust is
only water and water vapor. As they do not release emissions
such as CO
2 (Carbon Dioxide) and NOx (Nitrogen Oxides), fuel
cell vehicles are environm entally friendly vehicles.

The electric motor (traction motor) allows smooth, powerful takeoff
and acceleration. This vehicle dr ives similarly to a gasoline vehicle
without any special actions by the driver. ( P. 158) As there are no
engine sounds and the vehicle is q uiet, operation noises unique to
fuel cell vehicle com ponents may be heard. ( P. 8 0 )
The system may behave differently on cold days. It is performing a
special cold-start process to im prove start-up performance. (P. 175)
Operation noises ( P. 80), purge process ( P. 175), etc., differ from
usual. However, this is not a malfunction.
Compressed hydrogen gas fuel can be filled at hydrogen stations .

■Sounds unique to the fuel cell vehicle
Due to the design of your fuel cell vehicle, there are various relays, valves
and pumps which under normal driving conditions will produce so unds. This
is a normal characteristic of the vehicle and does not indicate a malfunction.
Furthermore, way of hearing may differ based on usage environme nt or con-
dition.
Noticeable soundsSource of the sounds
Clunking, clicking and clack-
ingOperation of relays and hydrogen tank
valves
Sounds may come from under the floor or
behind the rear seats.
(Sounds may be heard when starting the
fuel cell system.)
KnockingThe parking lock is engaged
Sounds may come from the motor
compartment.
(Sounds may be heard when press the P
position switch or stopping the fuel cell
system.)
Whooshing, squealingGas is flowing through the nozzle and
valvesSounds may come from behind the rear
seats, or from the dispenser hose/nozzle.
(Sounds may be heard when filling the
fuel.)
• High pitch sound
• Gurgle sound
• Pulsing soundOperation of the pumpsSounds may come from the motor com-
partment or under the front seats.
(In particular, sounds may be heard when
starting the fuel cell system, accelerating
from a stop, or press the H
2O switch. The
sound may be louder when in Br mode or
when the vehicle decelerates during
dynamic radar cruise control.)
Humming soundOperation of the pumps are speeding up
Sounds may come from the motor com-
partment or under the front seats.
(In particular, sounds may be heard when
accelerating or decelerating.)
Whooshing sound Operation of the hydrogen injectorSounds may come from under the front
seats or behind the rear seats.
(In particular, sounds may be heard when
starting the fuel cell system, driving at low
speeds, or charging the traction battery.)
