■Using the camera
If dirt or foreign matter (such as
water droplets, snow, mud, etc.)
is adhering to the camera, it
cannot transmit a clear image.
In this case, flush it with a large
quantity of water and wipe the
camera lens clean with a soft
and wet cloth.

■Cleaning the rear camera
with washer fluid
Dirt on the rear camera lens can
be cleaned by operating the dedicated camera cleaning
washer. For details, refer to
“OWNER’S MANUAL”.

When cleaning the camera, it
may be difficult to see the
image due to the washer fluid.
When backing up, be sure to
visually check all around the
vehicle both directly and using
the mirrors before proceed-
ing.
 If washer fluid remains on the
camera lens surface after
cleaning, the image may be
difficult to see at night due to
the height or inclination of the
headlights of the vehicle
behind.
 Some dirts may not be
removed completely after
cleaning. In this case, rinse
the camera lens with a large
quantity of water and then
wipe it clean with a soft cloth
dampened with water.
 Washer fluid is sprayed onto
the camera lens surface.
Therefore, the ice, snow, etc.
adhering around the camera
cannot be removed.
NOTICE
●The parking assist monitor may
not operate properly in the fol-
lowing cases.
• If the back of the vehicle is hit, the position and mounting angle
of the camera may change.
• As the camera has a water proof construction, do not
detach, disassemble or modify
it. This may cause incorrect
operation.
• When cleaning the camera lens, flush the camera with a large
quantity of water and wipe it
with a soft and wet cloth.
Strongly rubbing the camera
lens may cause the camera lens
to be scratched and unable to
transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or a
glass coating to adhere to the
camera. If this happens, wipe it
off as soon as possible.
• If the temperature changes rap- idly, such as when hot water is
poured on the vehicle in cold
weather, the system may not
operate normally.
• When washing the vehicle, do not apply intensive bursts of
water to the camera or camera
area. Doing so may result in the
camera malfunctioning.
●Do not expose the camera to
strong impact as this could
cause a malfunction. If this hap-
pens, have the vehicle
inspected by your Toyota dealer
as soon as possible.
NOTICE
●Do not strike or hit the washer
nozzle or subject it to a strong
impact, as the washer nozzle
installation position and angle
may be changed.

The distance guide lines and
the vehicle width guide lines
may not actually be parallel
with the dividing lines of the
parking space, even when
they appear to be so. Be sure
to check visually.
 The distances between the
vehicle width guide lines and
the left and right dividing lines
of the parking space may not
be equal, even when they
appear to be so. Be sure to
check visually.
 The distance guide lines give
a distance guide for flat road
surfaces. In any of the follow-
ing situations, there is a mar-
gin of error between the guide
lines on the screen and the
actual distance/course on the
road.
■When the ground behind
the vehicle slopes up
sharply
The distance guide lines will
appear to be closer to the vehi-
cle than the actual distance.
Because of this , objects will
appear to be farther away than
they actually are. In the same
way, there will be a margin of
error between the guidelines
and the actual distance/course
on the road.
■When the ground behind
the vehicle slopes down
sharply
The distance guide lines will
appear to be farther from the
vehicle than the actual distance.
Because of this, objects will
appear to be closer than they
actually are. In the same way,
there will be a margin of error
between the guidelines and the
actual distance/course on the
road.

■When any part of the vehi-
cle sags
When any part of the vehicle
sags due to the number of pas-
sengers or the distribution of the
load, there is a margin of error
between the guide lines on the
screen and the actual dis-
tance/course on the road.
A margin of error The estimated course lines tar-
get flat surfaced objects (such
as the road). It is not possible to
determine the position of three-
dimensional objects (such as
vehicles) using the estimated
course lines and distance guide
lines. When approaching a
three-dimensional object that
extends outward (such as the
flatbed of a truck), be careful of
the following.
■Estimated course lines
Visually check the surroundings
and the area behind the vehicle.
In the case shown below, the
truck appears to be outside of
the estimated course lines and
the vehicle does not look as if it
hits the truck. However, the rear
body of the truck may actually
cross over the estimated course
lines. In reality if you back up as
guided by the estimated course
lines, the vehicle may hit the
truck.
