Do not allow organic solvent, car
wax, window cleaner or paint coat-
ing to adhere to the camera. If this
happens, wipe it off as soon as
possible.
If the camera is subjected to a colli-
sion, or the camera orientation
confirmation lines are not in line
with the bumper, it is likely that the
camera position or angle of instal-
lation has become crooked. See
your T oyota dealer as soon as pos-
sible.
Use your own eyes to confirm the
vehicle’s surroundings, as the dis-
played image may become faint or
dark, and moving images will be
distorted, or not entirely visible
when the outside temperature is
low. When backing up, be sure to
check behind and all around the ve-
hicle visually and with mirror be-
fore proceeding.
Do not attach any accessories
within the detection range of the
sensors.
A sensor may not operate properly
in the following situations.
There is ice, snow or mud on the
sensor. (When it is removed, the
normal operation will return.)
The sensor is frozen. (When the
sensor warms up, it will return to
normal.) At low temperatures in
particular, sensors that are fro-
zen may not detect a parked ve-
hicle.
When the vehicle is tilted.
In extreme hot or cold weather.
When driving on bumpy roads,
slopes, gravelled roads or grass.
Devices issuing ultrasonic
waves are operated around your
vehicle, such as a horn from
another vehicle, motorcycle en-
gine, air braking sound from
heavyduty vehicles.
When rain or water is splashed
over the vehicle.
When a radio antenna or fender
pole is mounted on your vehicle.
The sensor approaches too
close to a parked vehicle.
The sensor is covered in any
way.
The bumper or sensor receives a
strong impact.
NOTICE
When washing the vehicle, do not ap-
ply intensive burst of water to the
camera or camera area. Doing so may
result in the camera malfunction.

INFORMATION
To allow the presupport system
to activate accurately, move the ve-
hicle as slowly as possible (at a
speed that will allow the vehicle to
be stopped suddenly).
 If only one vehicle is parked, the
presupport system cannot be
used.
 The function cannot be used if the
shift position is in “P” or “R”, or if
the vehicle speed is greater than 9
mph (15 km/h).
 In order to identify parking spaces
and detect parked vehicles using
the sensors on both sides of the
front bumper, guidance cannot be
given if a space is not detected.
 Parking space guidance and
searching continues until the ve-
hicle speed is greater than 9 mph
(15 km/h) or until the function is
turned off by pushing the presup-
port switch.
(a) When the presupport function is
in use
1Push the presupport switch
once
2Sensor detection range
1. With the vehicle speed at less than
9 mph (15 km/h) and the vehicle on the
near side of the parking space, push the
presupport switch once. Confirm that
the display has switched to the “Paral-
lel parking mode” screen.

not in use
1Approx. 3 ft. (1 m)
2Desired parking location
1. Move your vehicle slowly to a posi-
tion parallel to the road or shoulder
approximately 3 ft. (1 m) away from
parked vehicles.
To facilitate the setting of the target parking
position, the front side sensors detect the
vehicles parked in front of and behind the
parking space and identify the target park-
ing position.
2. Stop your vehicle in a position
where you can see the front edge of the
leading parked vehicle right beside
you, with the steering wheel straight.

(a) When the presupport function is
in use
1Push the presupport switch
twice
2Sensor detection range
1. With the vehicle speed at less than
9 mph (15 km/h) and the vehicle on the
near side of the parking space, push the
presupport switch twice. Confirm that
the display has switched to the “Back
in mode” screen.
INFORMATION
 The mode will switch with each
push of the presupport switch.
 If the shift position is in “P” or if the
vehicle speed is 9 mph (15 km/h) or
above, two beeps will sound when
the presupport switch is pushed,
and the display will not change.
 If the shift position is in “R”, the
display will not change.
2. Move the vehicle to a position per-
pendicular to the parking space, and as
close as possible to the parked vehicle.
INFORMATION
Move the vehicle forward as slowly
as possible so that the steering
wheel can be turned as soon as the
chime sounds.
 To cancel the guidance function,
turn off the presupport function
by pushing the presupport switch
once.

(b) When the presupport function is
not in use
1. Move your vehicle slowly to a posi-
tion perpendicular to the parking
space, and as close as possible to the
parking space.
Positioning the vehicle perpendicular to
the parking space allows the angle of the
parking position to be identified easily.
2. Move your vehicle to a position
where you can see the center of the
parking space right besides you.
To facilitate the setting of the target parking
position, the front side sensors detect the
vehicles parked at the left and right of the
parking space and identify the target park-
ing position.
It is possible to identify the target parking
position even if there is only a vehicle
parked on one side of the parking space.
If no vehicle or small vehicles are parked
on both sides of the desired parking space,
stop with the steering wheel straight.
By stopping the vehicle here, you can
mostly identify the parking location, mak-
ing it easier to set the target parking posi-
tion.
Make sure the steering wheel is straight
when you stop. If not, the parking location
cannot be identified.
If you do not stop in front of the parking
space, the system will refer to the angle of
the vehicle relative to the target parking
space, and display the target parking posi-
tion (green or red frame) in the position
used last time the parking assist mode was
activated.

8. Once the vehicle is mostly within
the target parking position, voice guid-
ance will give a message, and parking
assist mode will finish.
For safety, voice guidance is given slightly
before the target parking position. Further-
more, at that point system control will fin-
ish, so grip the steering wheel firmly, and
finish parking in the desired position, using
the brake to control the vehicle’s speed.
Check in front and behind the vehicle visu-
ally and check with the mirrors while back-
ing up.
Tips for setting the target parking
position
Useful information for setting the target
parking position (green frame)
THE DISPLAY POSITION OF THE
GREEN FRAME
The system decides the initial positioning
of the green frame by the position of the
parking space detected by the front side
sensors or the position of the vehicle when
it stops, and by detecting the white lines of
the parking space in the camera image to
identify the parking space location.
The front side sensors identify the parking
space location and the white lines near
that location are detected.
The front side sensors cannot identify the
parking space location, or the parking
space location may be misaligned in the
following situations.
A vehicle is parked at the back of the
parking space or the sensors cannot
detect a parked vehicle due to vehicle
shape etc.
The sensors cannot detect a pole or
wall beside the parking space.
The sensors detect a pedestrian or ob-
ject near the parking space.
If there are no vehicles parked on either
side of the target parking space when your
vehicle stops, the approximate parking
space location is identified, and the white
lines in that location are detected. For this
reason, stopping in front of the parking
space will make the detection of target
parking space’s white lines easier.
Successful detection of the parking
space’s white lines may not be possible,
depending on the shape of the line.
