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

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.
