WARNING
■Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resu lting in death
or serious injury.
● Remove any heavy loads, such as snow and ice, from the back doo r
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.
● When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.
● If anyone is in the vicinity, make sure they are safe and let t hem know that
the back door is about to open or close.
● Use caution when opening or closing the back door in windy weat her as it
may move abruptly in strong wind.
● Do not pull on the back door damper stay to close the back door , and do
not hang on the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to
break, causing an accident.
● If a bicycle carrier or similar 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 acces sory part
to the back door, using a genuine Toyota part is recommended.
● The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an
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 com-
partment.
● When closing the back door, take extra
care to prevent your fingers etc. from

Driving
WARNING
Observe the following precautions.
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”
indicator is illuminated. This prevents the vehicle from creepi ng.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the b rake
pedal will result in sudden acceleration that may lead to an ac cident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving t he
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● The driver should pay extra attention to pedestrians when the v ehicle is
powered only by the electric motor (traction motor). As there i s no engine
noise, the pedestrians may misjudge the vehicle’s movement. Eve n
though the vehicle is equipped with the vehicle proximity notif ication sys-
tem, drive with care as pedestrians in the vicinity may still n ot notice the
vehicle if the surrounding area is noisy.
● Do not drive the vehicle over or stop the vehicle near flammabl e materials
such as leaves, paper or rags.
The exhaust system and exhaust gases can be extremely hot. Thes e hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the hybrid system. Turni ng the hybrid
system off while driving will not cause loss of steering or bra king control,
however, power assist to the steering will be lost. This will m ake it more
difficult to steer smoothly, so you should pull over and stop t he vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 581

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft d rink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may le ad 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 ov er the
interior of the vehicle, and may also cause a short circuit 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 acci dentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do n ot place con-
tainers such as air fresheners on the instrument panel or dashb oard. Adhe-
sive 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 coate d with a
metallized film such as a silver-colored one. Reflected sunligh t may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift position to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
If the vehicle is parked with the shift position in P but the p arking brake is
not set, the vehicle may start to move, possibly leading to an accident.
