WARNING
●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
being caught.
● 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.

serious injury.
● Do not fold the seatbacks down while driving.

used.
● Be careful not to catch your hand when folding the rear seatbac ks.
● If it is necessary to detach the head restraints, remove it from the vehicle
or store it securely in the luggage compartment. This will prev ent it from
injuring passengers in the event of sudden braking, sudden swer ving or an
accident.
● Adjust the position of the front seat before folding down the rear seatbacks
so that the front seat does not interfere with the rear seatbacks when fold-
ing down the rear seatbacks.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is stopped
● Do not depress the accelerator pedal unnecessarily.
If the shift lever is in any position other than P or N, the vehicle may accel-
erate suddenly and unexpectedly, causing an accident.
● Do not leave the vehicle with the hybrid system on for a long t ime.
If such a situation cannot be avoided, park the vehicle in an o pen space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indic ator is
illuminated, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent ac cidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped m ay cause
the exhaust system to overheat, which could result in a fire if combustible

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this ma y cause
one side of the vehicle to brake differently than the other sid e. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid hills or sharp turns that require brak-
ing.
In this case, braking is still possible, but the brake pedal sh ould be
depressed more firmly than usual. Also, the braking distance wi ll increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In t his case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
NOTICE
■ When driving the vehicle
● Do not depress the accelerator and brake pedals at the same tim e during
driving, as this may restrain the hybrid system output.
● Do not use the accelerator pedal or depress the accelerator 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 lever to P. F ailure to do so
may cause the vehicle to move or the vehicle may accelerate sud denly if
the accelerator pedal is accidentally depressed.
