Press the power switch
shortly and firmly.

When operating the power switch,

one short, firm press is enough. It is

Check that the “READY” indi-
cator is illuminated.

The vehicle cannot be driven if the

“READY” indicator is off.

■

Starting the fuel cell system in

cold temperatures

●

When the fuel cell system is

started during cold temperatures,

the fuel cell stack quickly warms

up using waste heat during power

generation. Operation noises will

be louder than usually, but this is

not a malfunction. Depending on

the situation, the operation noises

may also continue for a fixed

period of time after the “READY”

indicator is turned on. (

●

When the temperatures are cold,

it may take more time than usual

until the “READY” indicator turns

on. In those cases, the progress

state is displayed in the multi-

information display.

●

When the traction battery is

extremely cold (below approxi-

mately -22˚F [-30˚C]) under the

influence of outside temperature,

it may not be possible to start the

fuel cell system. In this case, try to

start the fuel cell system again

after the temperature of the trac-

tion battery increases due to the

outside temperature increase etc.

■

If the fuel cell system does not

start

●

The immobilizer system may not

have been deactivated. (

■

Stopping the fuel cell system in

cold temperatures

●

When the power switch is pressed

and the fuel cell system is stopped

during cold temperatures, the time

for water purge from the tailpipe

may be longer than usual to pre-

vent liquid in the fuel cell stack

from freezing.

●

If the “FCV System Purge in Prog-

ress Purge will Stop Automati-

cally” is displayed in the multi-

information display, however it is

no problem to exit the vehicle.

●

The water purge time may also be

long if the system is stopped

before fuel cell system warm-up is

completed.

●

It is normal to hear hissing and

other sounds during purge.

(



P.77)

●

It is not a problem to do refueling

operations while the system is

purging.

The purging process is carried out

automatically after several min-

utes and a white mist may be

emitted, however this is not a mal-

function.

■

Parking the vehicle during cold

weather

●

Water may automatically purge

from the tailpipe, even when the

fuel cell system is off, in order to

prevent liquid in the fuel cell stack,

hydrogen pipelines, etc., from

freezing. Also, water vapor may

be purged, but this is not malfunc-

tion.

●

It is normal to hear hissing and

other sounds during purge.

WARNING

■

When starting the fuel cell

system

Always start the fuel cell system

while sitting in the driver’s seat.

Do not depress the accelerator

pedal while starting the fuel cell

system under any circumstances.

Doing so may cause an accident

resulting in death or serious injury.

NOTICE

■

When starting the fuel cell

system

If the fuel cell system becomes

difficult to start, have your vehicle

checked by your Toyota dealer

immediately.

■

Symptoms indicating a mal-

function with the power

switch

If the power switch seems to be

operating somewhat differently

Automatic fuel cell system shut

off feature

●

The vehicle is equipped with a

feature that automatically shuts off

the fuel cell system when the shift

position is in P with the fuel cell

system operating for an extended

period.

●

The fuel cell system will automati-

cally shut off after approximately 1

hour if it has been left running

while the shift position is in P.

●

The timer for the automatic fuel

cell system shut off feature will

reset if the brake pedal is

depressed or if the shift position is

in a position other than P.

●

After the vehicle is parked, if the

door is locked with the door lock

switch (

the mechanical key from the out-

side, the automatic fuel cell sys-

tem shut off feature will be

disabled. The timer for the auto-

matic fuel cell system shut off fea-

driver’s door is opened.

■

When the shift control system

malfunctions

When attempting to turn the power

switch off while there is a malfunc-

tion in the shift control system, the

power switch mode may change to

power switch while driving

except in an emergency. Turn-

ing the fuel cell system off while

driving will not cause loss of

steering or braking control, how-

ever, power assist to the steer-

ing will be lost. This will make it

more difficult to steer smoothly,

so you should pull over and stop

the vehicle as soon as it is safe

to do so.

●

If the power switch is operated

while the vehicle is running, a

warning message will be shown

on the multi-information display

and a buzzer sounds.
