WARNING
■When driving the vehicle
●Do not drive if y ou are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to dif-
ficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the
brake pedal using your left foot
may delay respon se in an emer-
gency, resulting in an accident.
●The driver should pay extra
attention to pedes trians as this
vehicle is powered only by an
electric motor (traction motor).
As there is no engine noise, the
pedestrians may misjudge the
vehicle’s movement. Even with
the acoustic vehicle alerting
system activate, d rive with care
as pedestrians in the vicinity
may still not notice the vehicle if
the surrounding area is noisy.
●During normal driving, do not
turn off the fuel cell system.
Turning the fuel cell system off
while driving will not cause loss
of steering or braking control,
however, power assist to the
steering 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.
In the event of a n emergency,
such as if it becomes impossible
to stop the vehicle in the normal
way:  P. 4 4 6
●Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness
when driving down a steep hill.
●Do not adjust the positions of
the steering wheel, the seat, or
the inside or outside rear view
mirrors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, heads or other parts
of their body are not outside the
vehicle.
●Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 85 mph (140 km/h)
unless your vehicle has high-
speed capability tires. Driving
over 85 mph (140 km/h) may
result in tire fa ilure, loss of con-
trol and possible injury. Be sure
to consult a tire dealer to deter-
mine whether the tires on your
vehicle are high-speed capabil-
ity tires or not before driving at
such speeds.
■When driving on slippery
road surfaces
●Sudden braking, acceleration
and steering may cause tire
slippage and reduce your ability
to control the vehicle.

1725-1. Before driving
Owners Manual_USA_M62064_en
WARNING
●Sudden acceleration or regen-
erative braking due to shifting
could cause the vehicle to skid.
●After driving through a puddle,
lightly depress the brake pedal
to make sure that the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift posi-
tion
●Do not let the vehicle roll back-
ward while a forward driving
position is selected, or roll for-
ward while the shift position is in
R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the shift position to
P while the vehicle is moving.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift position to
R while the vehicle is moving
forward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift position to
a driving position while the vehi-
cle is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Changing the shif t position to N
while the vehicle is moving will
disengage the fuel cell system.
Regenerative braking is not
available with the fuel cell sys-
tem disengaged.
●Be careful not to change the
shift position with the accelera-
tor pedal depressed. Changing
the shift position to any posi-
tions other than P or N may lead
to unexpected rapid accelera-
tion of the vehicle that may
cause an acciden t and result in
death or serious injury.
After changing the shift position,
make sure to confirm the cur-
rent shift position displayed on
the shift position indicator inside
the meter.
■If you hear a squealing or
scraping noise (brake pad
wear limit indicators)
Have the brake pads checked and
replaced by your Toyota dealer as
soon as possible.
Rotor damage may result if the
pads are not replaced when
needed.
It is dangerous to drive the vehicle
when the wear limits of the brake
pads and/or those of the brake
discs are exceeded.
■When the vehicle is stopped
●Do not depress the accelerator
pedal unnecessarily.
If the shift position is in any
position other than P or N, the
vehicle may accelerate sud-
denly and unexpectedly, caus-
ing an accident.
●In order to prevent accidents
due to the vehic le rolling away,
always keep depressing the
brake pedal while stopped with
the “READY” indicator is illumi-
nated, and apply the parking
brake as necessary.

WARNING
●The brake system consists of 2
or more individual hydraulic sys-
tems; if one of the systems fails,
the other(s) will still operate. In
this case, the brake pedal
should be depressed more
firmly than usual and the brak-
ing distance will increase. Have
your brakes fixed immediately.
NOTICE
■When driving the vehicle
●Do not depress t he accelerator
and brake pedals at the same
time during drivin g, as this may
restrain the fuel cell system out-
put.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■When parking the vehicle
Always set the parking brake, and
shift the shift position to P. Failure
to do so may cause the vehicle to
move or the vehi cle may acceler-
ate suddenly if the accelerator
pedal is accidentally depressed.
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering motor.
●When driving over bumps in the
road, drive as slowly as possible
to avoid damagi ng the wheels,
underside of the vehicle, etc.
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations. Hold the
steering wheel firmly and gradu-
ally depress the brake pedal to
slow down the vehicle.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.

of a flat tire ( P.467)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain, etc.
Doing so may cause the following
serious damage to the vehicle:
●Fuel cell system stalling
●Short in electrical components
●Fuel cell system damage
caused by water immersion
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toy-
ota dealer check the following:
●Fuel cell system
●Brake function

■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 ( P.130) from the inside or
the mechanical key from the out-
side, the automat ic fuel cell sys-
tem shut off feature will be
disabled. The tim er for the auto-
matic fuel cell system shut off fea-
ture will be re- enabled if the
driver’s door is opened.
■When the shift c ontrol 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
ACC. In this cas e, ACC may be
turned off by applying the parking
brake and pressing the power
switch again.

switch is pressed.)
WARNING
■Stopping the fuel cell system
in an emergency
●If you want to stop the fuel cell
system in an emergency while
driving the vehicle, press and
hold the power s witch for more
than 2 seconds, or press it
briefly 3 times or more in suc-
cession. ( P.446)
However, do not touch the
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.
●When restarting the fuel cell
system after an emergency
shutdown, press the power
switch.

reduce the impact of the colli-
sion.
■Emergency steering assist
If the system determines that
the possibility of a frontal colli-
sion is high and that there is suf-
ficient space for the vehicle to
be steered into within its lane,
and the driver has begun eva-
sive maneuver or steering,
emergency steering assist will
assist the steering movements
to help enhance the vehicle sta-
bility and for lane departure pre-
vention. During operation, the
indicator will illuminate in green.
■Intersection right/left turn
assistance
If the system determines that
there is a high possibility of a
collision in the following situa-
tions, it will assist with Pre-colli-
sion warning and, if necessary
Pre-collision braking.
Depending on the configuration
of the intersection, it may not be
possible to support.
 When you turn right/left at an
intersection and cross the
path of an oncoming vehicle 
When you turn right/left,
pedestrian is detected in the
forward direction and esti-
mated to enter your vehicle’s
path (bicyclists are not
detected.)
WARNING
■Limitations of the pre-colli-
sion system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
Do not use the pre-collision sys-
tem instead of normal braking
operations under any circum-
stances. This system will not
prevent collisions or lessen col-
lision damage or injury in every
situation. Do not overly rely on
this system. Failure to do so
may lead to an accident, result-
ing in death or serious injury.

WARNING
●Although this system is
designed to help avoid a colli-
sion or help reduce the impact
of the collision, its effectiveness
may change according to vari-
ous conditions, therefore the
system may not always be able
to achieve the same level of
performance.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.
• Conditions under which the sys- tem may operate even if there is
no possibility of a collision:
 P. 2 2 6
• Conditions under which the sys- tem may not operate properly:
 P. 2 2 7
●Do not attempt to test the oper-
ation of the pre-collision system
yourself.
Depending on the objects used
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system
may not operate properly, possi-
bly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision
braking function, the pre-colli-
sion braking function operation
will be canceled after approxi-
mately 2 second s. Depress the
brake pedal as necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●In some situations, while the
pre-collision brak ing function is
operating, operation of the func-
tion may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is
turned and the system deter-
mines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may
determine that t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision braking function.
■Emergency steering assist
●As emergency steering assist
operation will be canceled when
the system determines that lane
departure prevention function
has been completed.
●Emergency steering assist may
not operate or may be cancel in
the following cases as the sys-
tem may determine the driver is
taking actions.
• If the accelerator pedal is being depressed strongly, the steering
wheel is being operated sharply,
the brake pedal is being
depressed or the turn signal
lever is being operated. In this
case, the syst em may deter-
mine that the driver is taking
evasive action and the emer-
gency steering assist may not
operate.

■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on
( P.512) of the multi-informa-
tion display.
The warning timing setting is
retained when the power switch is
turned off. However , if the pre-colli-
sion system is disabled and re-
enabled, the operation timing will
return to the default setting (mid-
dle).
If the pre-collision warning tim-
ing is changed, emergency
steering assist timing will also
be changed accordingly.
If late is selected, emergency
steering assist would not oper-
ate in case of an emergency.
1 Early
2 Middle
This is the default setting.
3Late
■Operational conditions for e ach pre-collision function
The pre-collision syst em is enabled and the system determines t hat the pos-
sibility of a frontal c ollision with a detected object is high.
The system may not operate in the following situations:
• If a 12-volt battery terminal has been di sconnected and reconn ected and
then the vehicle has not been dr iven for a certain amount of time
• If the shift position is in R
• When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)
The operation speeds and operati on cancelation for each function is listed
below.
