THE CAMERA
The camera for the parking assist moni-
tor is located as shown in the illustration.
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 im-
age. In this case, flush it with a large
quantity of water and wipe the camera
lens clean with a soft and wet cloth.
NOTICE
●The parking assist monitor may not oper-
ate properly in the following cases.
• If the back of the vehicle is hit, the posi- tion and mounting angle of the camera
may change.
• As the camera has a water proof con- struction, 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 glass coat to adhere
to the camera. If this happens, wipe it off
as soon as possible.
• If the temperature changes rapidly, 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 happens, have the vehicle
inspected by any authorized Lexus dealer
or repairer, or another duly qualified and
equipped professional as soon as possi-
ble.

zThe distance guide lines and the vehicle
width guide lines may not actually be paral-
lel with the dividing lines of the parking
space, even when they appear to be so. Be
sure to check visually.
z 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.
z The distance guide lines give a distance
guide for flat road surfaces. In any of the
following situations, there is a margin of
error between the guide lines on the screen
and the actual distance /course on the road.
DIFFERENCES BETWEEN THE
SCREEN AND THE ACTUAL
ROADWHEN THE GROUND BEHIND
THE VEHICLE SLOPES UP
SHARPLY
The distance guide lines will appear to
be closer to the vehicle than the actual
distance. Because of this, objects will ap-
pear to be farther away than they actual-
ly 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 further from the vehicle than the ac-
tual distance. Because of this, objects
will appear to be closer than they actual-
ly 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
VEHICLE SAGS
When any part of the vehicle sags due to
the number of passengers or the distri-
bution of the load, there is a margin of er-
ror between the guide lines on the
screen and the actual distance/course
on the road.
WHEN APPROACHING
THREE-DIMENSIONAL
OBJECTS
The estimated course lines target a flat
surfaced objects (such as the road). It is
not possible to determine the position of
three-dimensional objects (such as vehi-
cles) using the estimated course lines
and distance guide lines. When ap-
proaching a three-dimensional object
that extends outward (such as the flat-
bed of a truck), be careful of the follow-
ing.

XEstimated course lines
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 esti-
mated course lines. In reality if you back
up as guided by the estimated course
lines, the vehicle may hit the truck.DISTANCE GUIDE LINES
Visually check the surroundings and the
area behind the vehicle. On the screen,
it appears that a truck is parking at point
B. However, in reality if you back up to
point A, you will hit the truck. On the
screen, it appears that A is closest and C
is furthest away. However, in reality, the
distance to A and C is the same, and B is
farther than A and C.
