WARNING
●Vehicles without power back
door: The back door may sud-
denly shut if it is not opened

incline than on a level surface,
so beware of the back door
unexpectedly opening or closing
by itself. Make sure that the
back door is fully open and
secure before using the luggage
compartment.
●Vehicles with power back door:
The back door may suddenly
shut if it is not opened fully,
while on a steep incline. Make
sure that the back door is
secured before using the lug-
gage compartment.
●When closing the back door,
take extra care to prevent your
fingers, etc. from being caught.
●Vehicles without power back
door: When closing the back
door, make sure to press it
lightly on its outer surface. If the
back door handle is used to fully
close the back door, it may
result in hands or arms being
caught.
●Do not pull on the back door
damper stay (vehicles without
power back door) ( P.194) or
back door spindle (vehicles with
power back door) ( P.201) to
close the back door, and do not
hang on the back door damper
stay (vehicles without power
back door) or back door spindle
(vehicles with power back door).
Doing so may cause hands to
be caught or the back door
damper stay (vehicles without
power back door) or back door
spindle (vehicles with power
back door) to break, causing an
accident.
●Vehicles without power back
door: If a bicycle carrier or simi-
lar heavy object is attached to
the back door, it may suddenly
shut again after being opened,
causing someone’s hands,
head or neck to be caught and
injured. When installing an
accessory part to the back door,
using a genuine Toyota part is
recommended.

2004-2. Opening, closing and locking the doors
WARNING
■Back door closer
●In the event that the back door
is left slightly open, the back
door closer will automatically
close it to the fully closed posi-
tion. It takes several seconds
before the back door closer
begins to operate. Be careful
not to catch fingers or anything
else in the back door, as this
may cause bone fractures or
other serious injuries.
●Use caution when using the
back door closer as it still oper-
ates when the power back door
system is canceled.

Observe the following precautions
when operating the power back
door.
Failure to do so may cause death
or serious injury.
●Check the safety of the sur-
rounding area to make sure
there are no obstacles or any-
thing that could cause any of
your belongings to get caught.
●If anyone is in the vicinity, make
sure they are safe and let them
know that the back door is
about to open or close.
●If the power back door system is
turned off while the back door is
operating automatically, the
automatic operation is stopped.
The back door then has to be
operated manually. Take extra
care when on an incline, as the
back door may open or close
unexpectedly.
●If the operating conditions of the
power back door are no longer
met, a buzzer may sound and
the back door may stop opening
or closing. The back door then
has to be operated manually.
Take extra care when on an
incline, as the back door may
open or close abruptly.
●On an incline, the back door
may suddenly shut after it
opens. Make sure the back door
is fully open and secure.
●In the following situations, the
power back door may detect an
abnormality and automatic
operation may be stopped. In
this case, the back door has to
be operated manually. Take
extra care when on an incline,
as the back door may open or
close abruptly.
• When the back door contacts an obstacle
• When the 12-volt battery volt- age suddenly drops, such as
when the power switch is turned
to ON or the hybrid system is

Driving
WARNING
■When driving the vehicle
●Do not drive if you 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 a
difficulty 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 response in an emer-
gency, resulting in an accident.
●The driver should pay extra
attention to pedestrians when
the vehicle is powered only by
the electric motor (traction
motor). As there is no engine
noise, the pedestrians may mis-
judge the vehicle’s movement.
Even if the Acoustic Vehicle
Alerting System is operating,
drive with care as pedestrians in
the vicinity may still not notice
the vehicle if the surrounding
area is noisy.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials such as leaves, paper
or rags.
The exhaust system and
exhaust gases can be
extremely hot. These hot parts
may cause a fire if there is any
flammable material nearby.
●During normal driving, do not
turn off the hybrid system. Turn-
ing the hybrid s ystem off while
driving will not cause loss of
steering or braking control.
However, power assist for the
steering wheel may be lost mak-
ing it difficult to steer smoothly
before stopping the vehicle
depending on the remaining
charge in the 12-volt battery or
usage conditions. In this situa-
tion, you should pull over and
stop the vehicle as soon as it is
safe to do so.
In the event of an emergency,
such as if it be comes impossible
to stop the vehicle in the normal
way:  P.547
●Use engine braking (downshift)
to maintain a safe speed when
driving down a steep hill.
Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness.
( P.256)
●Do not adjust the position of the
steering wheel, the seat, inside
rear view mirror (if equipped),
Digital Rear-view Mirror (if
equipped) or outside rear view
mirrors while driving.
Doing so may resu lt in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, head or other parts
of their body are not outside the
vehicle.
