den acceleration. ( P. 9 1 )
■Driving in the rain
●Drive carefully whe n it is raining,
because visibility will be reduced,
the windows may become fogged-
Driving the vehicle
The following procedures
should be observed to
ensure safe driving:
Driving procedure

1705-1. Before driving
Owners Manual_USA_M62064_enup, and the
road will be slippery.
●Drive carefully whe n it starts to
rain, because the road surface will
be especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■ECO Accelerator Guidance
(  P.108)
Eco-friendly driving may be
achieved more easily by staying
within the zone of Eco acceleration.
Also, by staying w ithin the zone of
Eco acceleration, i t will be easier to
obtain a good Eco score.
●When starting off:
Gradually depress the accelerator
pedal to stay withi n the zone of Eco
acceleration and accelerate to the
desired speed. By refraining from
excessive acceleration, a good eco
start score will be obtained.
●When driving:
After accelerating to the desired
speed, release the accelerator
pedal and drive at a stable speed
while staying within the zone of Eco
acceleration. By staying within the
zone of Eco acceleration, a good
eco cruise score will be obtained.
●When stopping:
By starting to release the accelera-
tor pedal early before decelerating,
a good eco stop score will be
obtained.
■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.
■Breaking in your new Toyota
To extend the life of the vehicle,
observing the following precautions
is recommended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low
gears.
• Do not drive at a constant speed
for extended periods.
■Drum-in-disc type parking
brake system
Your vehicle has a drum-in-disc type
parking brake system. This type of
brake system needs bedding-down
of the brake shoes periodically or
whenever the par king brake shoes
and/or drum are replaced. Have
your Toyota dealer perform the bed-
ding down operation.
■Operating your v ehicle in a for-
eign country
Comply with the relevant vehicle
registration laws and confirm the
availability of the correct fuel.
(  P.497)
WARNING
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
■When starting the vehicle
Always keep your foot on the
brake pedal while stopped with
the “READY” indica tor is illumi-
nated. This prevents the vehicle
from creeping.

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.

Driving
WARNING
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle roll-
ing forward or backward, always
depress the brake pedal and
securely apply the parking
brake as needed.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft
drink cans in the vehicle when it
is in the sun.
Doing so may result in the fol-
lowing:
• Gas may leak from a cigarette lighter or spray can, and may
lead to a fire.
• The temperature inside the vehicle may cause the plastic
lenses and plastic material of
glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray
over the interior of the vehicle,
and may also caus e a short cir-
cuit in the vehicle’s electrical
components.
●Do not leave cigarette lighters in
the vehicle. If a cigarette lighter
is in a place such as the glove
box or on the floor, it may be lit
accidentally when luggage is
loaded or the seat is adjusted,
causing a fire.
●Do not attach adhesive discs to
the windshield or windows. Do
not place containers such as air
fresheners on the instrument
panel or dashboard. Adhesive
discs or containers may act as
lenses, causing a fire in the
vehicle.
●Do not leave a door or window
open if the curved glass is
coated with a metallized film
such as a silver-colored one.
Reflected sunlight may cause
the glass to act a s a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift position to P, stop
the fuel cell system and lock the
vehicle.
Do not leave the vehicle unat-
tended while the “READY” indi-
cator is illuminated.
If the vehicle is parked with the
shift position in P but the park-
ing brake is not set, the vehicle
may start to move, possibly
leading to an accident.
■When taking a nap in the vehi-
cle
Always turn the fuel cell system
off. Otherwise, if you accidentally
move the shift lever or depress
the accelerator pedal, causing the
vehicle to unintentionally move,
which can lead to an accident,
resulting in death o r serious injury.
■When braking
●When the brakes are wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this may cause one side of the
vehicle to brake d ifferently than
the other side. Also, the parking
brake may not securely hold the
vehicle.
●If the electronically controlled
brake system does not operate,
do not follow other vehicles
closely and avoid hills or sharp
turns that require braking.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.

1745-1. Before driving
Owners Manual_USA_M62064_en
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.
Information on what to do in case
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
●Changes in quantity and quality
of transmission fluid, etc.
●Lubricant condition for the bear-
ings and suspension joints
(where possible), and the func-
tion of all joints, bearings, etc.

Driving
When the following unusual
operation is performed with the
accelerator pedal depressed,
the fuel cell system output may
be restrained.
• When the shift position is shifted to R
*.
• When the shift position is shifted from P or R to forward
drive shift position such as D
*.
When the system op erates, a mes-
sage appears on the multi-informa-
tion display. Read the message and
follow the instruction.
*: Depending on the situation, the shift position may not be
changed.
■Drive-Start Control (DSC)
●When the TRAC is turned off
( P.323), sudden start restraint
control also does not operate. If
your vehicle have trouble escap-
ing from the mud or fresh snow
due to sudden start restraint con-
trol operation, deactivate TRAC
(  P.323) so that the vehicle may
become able to e scape from the
mud or fresh snow.
Cargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) — (Total weight of
occupants)
Steps for Determining Correct
Load Limit —
(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals
the available amount of cargo
and luggage load capacity.
For example, if the “XXX”
amount equals 1400 lbs. and
there will be five 150 lb passen-
gers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1400 −
750 (5  150) = 650 lbs.)
NOTICE
If the shift control system is dam-
aged by flooding, it may not be
possible to shift t he shift position
to P, or from P to other positions.
In this case, contact your Toyota
dealer.

trol [DSC])
Cargo and luggage
Take notice of the following
information about storage
precautions, cargo capacity
and load:
Capacity and distribution

1765-1. Before driving
Owners Manual_USA_M62064_en
(5) Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo and
luggage load capacity calcu-
lated in Step 4.
(6) If your vehicle will be towing
a trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.
(P.178)
Toyota does not recommend towing
a trailer with your vehicle. Your
vehicle is not designed for trailer
towing.
Cargo capacity
Total load capacity (vehicle
capacity weight) ( P.496)
When 2 people with the com-
bined weight of A lb. (kg) are rid-
ing in your vehicle, which has a
total load capacity (vehicle capacity weight) of B lb. (kg),
the available amount of cargo
and luggage load capacity will
be C lb. (kg) as follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb.
(kg)
*1: A =Weight of people
*2: B =Total load capacity
*3: C =Available cargo and luggage load
In this condition, if 3 more passen-
gers with the combined weight of D
lb. (kg) get on, the available cargo
and luggage load will be reduced E
lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb.
(kg)
*4: D =Additional weight of people
*5: E =Available cargo and luggage load
As shown in the example above,
if the number of occupants
increases, the cargo and lug-
gage load will be reduced by an
amount that equals the
increased weight due to the
additional occupants. In other
words, if an increase in the num-
ber of occupants causes an
excess of the total load capacity
(combined weight of occupants
plus cargo and luggage load),
you must reduce the cargo and
luggage on your vehicle.
