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.

The advanced parking guidance
system camera
The advanced parking guidance system
camera is located on the back door as
shown in the illustration.
The camera uses a special lens. The dis-
tance of the image that appears on the
screen differs from the actual distance.
In the following cases, it may become diffi-
cult to see the images on the screen, even
when the system is functioning.
In the dark (for example, at night)
When the
temperature near the lens is
extremely high or low
When water droplets are adhering to
the camera, or when humidity is high
(for example, when it rains)
When foreign matter (for example,
snow or mud) adheres to the camera
lens
When the camera has scratches or dirt
on it
When the sun or the beam of head-
lights is shining directly into the camera
lens
If a bright light (for example, sunlight re-
flected off the vehicle body) is picked up by
the camera, the smear effect
∗, peculiar to
the CCD camera, may occur.
∗: Smear effect—A phenomenon that oc-
curs when a bright light (for example, sun-
light reflected off the vehicle body) is
picked up by the camera; when trans-
mitted by the camera, the light source ap-
pears to have a vertical streak above and
below it.
If you install the antenna of a wireless de-
vice close to the camera, the screen image
may be affected by the electromagnetic
waves, and the system may not function
correctly. Install an antenna away from the
camera.
The method for adjusting the picture quali-
ty of the advanced parking guidance sys-
tem is the same as that for the navigation
screen.

ADVANCED PARKING GUIDANCE SYSTEM

Instructions given are only examples.
When and how much to turn the steer-
ing wheel will vary according to traffic
conditions, road surface conditions,
vehicle condition, etc. when parking.
It is necessary to be fully aware of this
before using the
advanced parking
guidance system.
Also, when parking, be sure to check
that the parking space will accommo-
date your vehicle before maneuvering
into it.
CAUTION
Depending on the circumstances of
the vehicle (number of passengers,
amount of luggage, etc.), the set tar-
get parking position displayed on the
screen may change. Be sure to check
visually behind and all around the ve-
hicle before proceeding.
(a) To activate the advanced parking
guidance system
To activate the advanced parking guid-
ance system, shift to “R” when the
“POWER” switch is in ON mode.
If you move the shift position out of “R”,
the screen returns to the previous
screen. Operating another function of
the navigation system will display
another screen.
Even if the shift position is in “R”, if you
push any of the mode buttons around
the display, such as “MAP/VOICE” or
“INFO·PHONE” , the screen will switch
to that mode.

In any of the following situations, there
is a margin of error between the set tar-
get parking position on the screen and
the actual distance/course on the road.
When the grade behind the vehicle
slopes up sharply, objects appear to
be farther away than they actually
are.
—Driving precautions

ADVANCED PARKING GUIDANCE SYSTEM
201
When the grade behind the vehicle
slopes down sharply, objects ap-
pear to be closer than they actually
are.
When any part of the vehicle sags
due to the number of passengers or
the distribution of the load, there is
a margin of error between the set
target parking position on the
screen and the actual distance/
course on the road.

ADVANCED PARKING GUIDANCE SYSTEM
202
Parallel parking assist mode assists
the driver with parallel parking by auto-
matically controlling the steering wheel
when backing up, in order to park in the
target position set on the screen.
CAUTION
When backing up, be sure to check
your surroundings and behind the
vehicle for safety, and back up
slowly, depressing the brake pedal
to control vehicle speed.
If you seem likely to hit nearby ve-
hicles, obstacles or people, de-
press the brake pedal to stop the
vehicle, then disable the system by
touching on the screen.
As the system only assists with parking in
a set target parking position, there are
times when the system will be unable to
render this assistance, depending on fac-
tors such as road surface or vehicle condi-
tion, or the distance to the set target park-
ing position.
Use the system with full understanding of
the fact.
If a message is displayed while maneuver-
ing, follow the procedures outlined in “ —
What to do when this sort of message is
displayed” on page 226.
The illustrations here describe the proce-
dure for pulling into a parking space on the
right. For pulling into a parking space on
the left, substitute left for right and vice ver-
sa in all steps.
The operating method differs depending
on whether or not the pre− support function
is in use. PRESUPPORT FUNCTION
The presupport function can be used
when there is a space between two
parked vehicles. If a parking space is
detected, this function will inform the
driver using a tone when the vehicle is
in a position to begin backing up, and
guides the vehicle to a position from
which assistance can be given.
Guidance will not be given if the detected
space is narrow.

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

9 mph (15 km/h) and the vehicle on the
near side of the parking space, push the
presupport swi tch once. Confirm that
the display has switched to the “Paral-
lel parking mode” screen.
