When the window cannot be opened or closed
When the jam protection function or catch protection function o perates
unusually and the door window cannot be opened or closed, perfo rm the fol-
lowing operations with the power window switch of that door.
● Stop the vehicle. With the power switch in ON mode, within 4 se conds of the
jam protection function or catch protection function activating , continuously
operate the power window switch in the one-touch closing direct ion or one-
touch opening direction so that the door window can be opened a nd closed.
● If the door window cannot be opened and closed even when perfor ming the
above operations, perform the following procedure for function initialization.
Turn the power switch to ON mode.
Pull and hold the power window switch in the one-touch closing direction
and completely close the door window.
Release the power window switch for a moment, resume pulling the
switch in the one-touch closing direction, and hold it there for approxi-
mately 6 seconds or more.
Press and hold the power window switch in the one-touch opening direc-
tion. After the door window is completely opened, continue hold ing the
switch for an additional 1 second or more.
Release the power window switch for a moment, resume pushing th e
switch in the one-touch opening direction, and hold it there fo r approxi-
mately 4 seconds or more.
Pull and hold the power window switch in the one-touch closing direction
again. After the door window is completely closed, continue holding the
switch for a further 1 second or more.
If you release the switch while the window is moving, start aga in from the
beginning. If the window reverses and cannot be fully closed or opened, have
the vehicle inspected by your Toyota dealer.

■When starting off on an uphill
The hill-start assist control will activate. ( P. 231)
■ For fuel-efficient driving
Keep in mind that fuel cell vehicles are similar to conventiona l vehicles, and it
is necessary to refrain from activities such as sudden acceleration. ( P. 94)
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the r ain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properl y.
■ Restraining the fuel cell system output (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
fuel cell system output may be restrained.
● A warning message is displayed on the multi-information display while the
system is operating. If a warning message is shown on the multi -information
display, read the message and follow the instructions.
■ Restraining sudden start (Drive-Start Control)
● When the following unusual operation is performed, the fuel cel l system out-
put may be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to
R with the accelerator pedal depressed, a warning message appea rs on
the multi-information display. If a warning message is shown on the multi-
information display, read the message and follow the instructio ns.
• When the accelerator pedal is depressed too while the vehicle is in
reverse.
● While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactiva te TRAC
(  P. 232) to cancel Drive-Start Control so that the vehicle may b ecome
able to escape from the mud or fresh snow.

2O switch.
The H
2O indicator on the meter
turns on.
Press the switch again to stop the

Starting the fuel cell syst em in cold temperatures
● When the power switch is pressed and the fuel cell system start s (P. 172)
during cold temperatures, the fuel cell stack is quickly warmed up using the
waste heat during power generation.
● When the temperatures is cold, it may take some time until the “READY”
indicator turns on.
● When starting the fuel cell system during cold weather, “FC Sys tem Shut-
down due to Freezing conditions Stop Your Vehicle in a Safe Place and
Contact Your Dealer” may be displayed in the multi-information display.
The fuel cell system is frozen and can not be started. Contact a Toyota
dealer.
● The power output will be temporarily limited until the fuel cel l system
reaches full operating temperature.
● The fuel cell system noises may become louder when the temperat ure is
cold. This is the normal warm-up operation and is not a malfunc tion. In
some cases, operation noises may continue for a some time even after the
“READY” indicator has turned on. ( P. 80)
■ Stopping the fuel cell syst em in cold temperatures
● When the power switch is pressed and the fuel cell system is stopped
( P. 173) during cold temperatures, the time for water purge from the tail-
pipe may be longer than usual to prevent liquid in the fuel cel l stack from
freezing.
● 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. 80)
● The H
2O indicator on the meter will illuminate during purge.
●
In extremely cold temperatures, the
“READY” indicator may take more than
10 seconds to illuminate. In this case,
the status progression of the fuel cell
system startup is displayed on the multi-
information display.

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 stac k, hydrogen pipe-
lines, etc., from freezing.
● It is normal to hear hissing and other sounds during purge. ( P. 80)
● The H
2O indicator on the meter will illuminate during purge.
■ Water release function during cold weather
In the following cases, the fuel cell system automatic drainage may not oper-
ate. It may not be possible to start the fuel cell system due t o the fuel cell
stack, hydrogen pipes, etc, being frozen.
• When transporting or towing the vehicle in frozen areas
• When the 12-volt battery terminals are disconnected and remain as such
in frozen areas
Operate the water release function with the following procedure beforehand
to prevent water from freezing in the system.
Turn the power switch to ON mode and press the H
2O switch.
Check that the H
2O indicator on the meter turns on.
While depressing the brake, press the power switch to start the fuel cell
system.
Check that the “READY” indicator turns on.
Press the power switch to stop the fuel cell system.
The water release is automatically performed. During water purg e, the
H
2O indicator turns on. (Longer than normal water purge)

■For the shift positions
●When the power switch is off, the shift position cannot be chan ged.
● When the power switch is in ON mode (the fuel cell system is not operating),
the shift position can only be changed to N. The shift position will be
changed to N even if the shift position is shifted to D or R and held in that
position.
● When the “READY” indicator is on, the shift position can be cha nged from P
to D, N or R.
● When the “READY” indicator is flashing, the shift position cann ot be
changed from P to another position even if the shift lever is o perated.
Wait until the “READY” indicator changes from a flashing to a s olid light, and
then operate the shift lever again.
In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, a buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happen s, select an
appropriate shift position.
● When attempting to change the shift position from P without dep ressing the
brake pedal, the shift position change is invalidated.
● Situations where the shift position will automatically change t o N:
• When the P position switch is pressed while the vehicle is running.
*1
• When an attempt is made to select the R position by moving the shift
lever when the vehicle is moving forward.
*2
• When an attempt is made to select the D position by moving the shift
lever when the vehicle is moving in reverse.
*3
• When an attempt is made to change the shift position from R to Br mode
by moving the shift lever.
*1: Shift position may be changed to P when driving at extremely l ow speeds.
*2: Shift position may be changed to R when driving at low speeds.
*3: Shift position may be changed to D when driving at low speeds.
■ Br mode
Depending on the condition of the traction battery, Br mode may not be avail-
able.
In that case, a message is displayed on the multi-information d isplay.
■ Sounds when in Br mode
