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.

completed.
●It is normal to hear hissing and
other sounds during purge.
(  P. 7 7 )
●It is not a problem to do refueling
operations while the system is
purging.
The purging process is carried out
automatically afte r several min-
utes and a white mist may be
emitted, however this is not a mal-
function.
■Parking the vehic le 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.
