■Jam protection function
Sensors are installed on the right
and left sides of the power back
door. When the door is automati-
cally closing and the sensors are
pushed due to an object being
clamped, etc., the jam protection
function operates.
From that position the door auto-
matically moves a little in the oppo-
site direction and then the function
stops.
■Back door reserve lock function
This function reserves the locking of
the power back door when the
power back door is open. If the fol-
lowing operations are performed, all
of the doors except the power back
door will lock and t hen the power
back door will lock when it is com-
pletely closed.

back door.
2 Perform an automatic closing
operation of the power back door
and lock the doors using the
wireless remote control
( P.131) or smart key system
(  P.131) while the power back
door is closing.
A buzzer sounds and the emer-
gency flashers flash to indicate that
all the doors have been closed and
locked.
●If the electronic key is placed
inside the vehicle after starting a
close operation via the door
reserve lock function, the elec-
tronic key may become locked
inside the vehicle.
●If the back door does not fully
close due to the operation of the jam protection function, etc., while
the back door is automatically
closing after a do
or reserve lock
operation is performed, the door
reserve lock function is canceled
and all the doors will unlock.
●Before leaving the vehicle, make
sure that all the doors are closed
and locked.

■When using the intuitive park-
ing assist
Observe the following precau-
tions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.
●Do not use the sensor at
speeds in excess of 6 mph (10
km/h).
●The sensors’ detection areas
and reaction times are limited.
When moving forward or revers-
ing, check the areas surround-
ing the vehicle (especially the
sides of the vehicle) for safety,
and drive slowly, using the
brake to control the vehicle’s
speed.
●Do not install accessories within
the sensors’ d etection areas.
●The area directly under the
bumpers is not detected.
Thin posts or objects lower than
the sensor may not be detected
when approached, even if they
have been det ected once.
■When to disable the function
In the following situations, disable
the function as it may operate
even though there is no possibility
of a collision.
●The vehicle is equipped with a
fender pole, wireless antenna or
fog lights.
●The front or rear bumper or a
sensor receives a strong
impact.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
●To w i n g e y e l e t s are installed.
●A backlit licence plate is
installed.
■When using intuitive parking
assist
In the following situations, the
system may not function correctly
due to a sensor malfunction, etc.
Have the vehicle checked by your
Toyota dealer.
●The intuitive parking assist
operation display flashes or
shows continuously, and a
buzzer sounds when no objects
are detected.
●If the area around a sensor col-
lides with something, or is sub-
jected to strong impact.
●If the bumper or grille collides
with something.
●If the display flashes or is dis-
played continuously and a
buzzer does not sound, except
when the mute function has
been turned on.
●If a display error occurs, first
check the sensor.
If the error occurs even when
there is no ice, snow or mud on
the sensor, it is likely that the
sensor is malfunctioning.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.

when
●The power switch is in ON.
●Intuitive parking assist function is
on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●A shift lever other than P.
■If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
●Water may be continuously flow-
ing over the sensor surface, such
as in a heavy rain. When the sys-
tem determines that it is normal,
the system will re turn to normal.
●Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
(  P.289) If this message contin-
ues to be displayed even after ini-
tialization, have the vehicle
inspected by you r Toyota dealer.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., from the sensor to
return the syste m to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
■If a 12-volt battery terminal has
been disconnected and recon-
nected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
22 mph (35 km/h) or more.
■Sensor detection information
●The following situations may occur
during use.
• The sensor's detec tion areas are
limited to the areas around the
vehicle front and rear bumpers.
• Depending on the shape of the object and other factors, the
detection distance may shorten, or
detection may be impossible.
• If an object is extremely close to a sensor, it may not be detected.
• There will be a short delay between object detection and dis-
play. Even at low speeds, there is
a possibility tha t the object will
come within the sensor’s detec-
tion areas before the display is
shown and the warning beep
sounds.
• It might be diffic ult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be diffi cult to hear the
buzzer if buzzers for other sys-
tems are sounding.
■Conditions under which the
function may not function cor-
rectly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Part icular instances
where this may occur are listed
below.
●There is dirt, snow or ice on a sen-
sor. (Cleaning the sensors will
resolve this problem.)
●A sensor is froz en. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
