782-1. Fuel cell electric vehicle
Owners Manual_USA_M62064_en
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling,
and disposal. Do not dispose of the
vehicle or any of its components
yourself.
The electric motor (traction
motor) allows smooth, powerful
takeoff and acceleration. This
vehicle drives similarly to a gas-
oline vehicle without any special
actions by the driver. ( P.169)
As there are no engine sounds
and the vehicle is quiet, opera-
tion noises unique to fuel cell
electric vehicle components
may be heard. ( P.77)
■Regenerative braking
In the following si tuations, the vehi-
cle generates electricity from the
deceleration of the vehicle while
driving.
●The accelerator pedal is released
while driving with the shift position
in D.
●The brake pedal is depressed
while driving with the shift position
in D.
■Charging the traction battery
Because electricity generated by the
fuel cell stack and regenerative
braking charges the traction battery,
the battery does not need to be
charged from an outside source.
However, if the vehicle is left parked
for a long time, the traction battery
will slowly discharge. For this rea-
son, be sure to drive the vehicle at
least once every few months for at
least 30 minutes or 10 miles (16
km). If the traction ba
ttery becomes fully
discharged and yo u are unable to
start the fuel cell system, contact
your Toyota dealer.
■Charging the 12-volt battery
 P.487
■Sounds and vibrations specific
to a fuel cell e lectric vehicle
Because there is no engine sound
or vibration, it is easy to mistake the
fuel cell electric vehicle for being off
when it is actually still running, as
indicated by the “READY” indicator
being illumina ted. For safety, make
sure to always shift the shift position
to P and apply the parking brake
when parked.
The system may behave differ-
ently on cold days as it may be
performing a special cold-start
process to improve the start up
performance. ( P.180)
Operation noises ( P.77),
purge process ( P.182), etc.,
may differ from usual. However,
this is not a malfunction.
Compressed hydrogen gas fuel
can be filled at hydrogen sta-
tions.
More information about hydrogen
fuel and fueling can be found in the
“Opening the fuel door” section of
this manual. ( P.210)

onto an aircraft, make sure you do
not press any buttons on the elec-
tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag, etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin and a
message will be s hown on the
multi-information display when the fuel cell system is stopped.
●To reduce key battery depletion
when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. (
P.137)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary.
• The smart key system or the wire- less remote contro l does not oper-
ate.
• The detection area becomes smaller.
• The LED indicator on the key sur- face does not turn on.
