■Rear view monitor system camera
The camera for the rear view moni-
tor system is located above the
license plate.
●Using the camera
If the camera lens becomes dirty, it cannot transmit a clear image. If water
droplets, snow or mud adhere to the lens , rinse it with water and wipe with a
soft cloth. If the lens is extremely dirty, wash it with a mild cleanser and rinse.
■Differences between the screen and the actual road
The distance guide lines and the vehicl e 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 following situations, there is a margin of error between the fixed 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 vehicle 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 further 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 vehicle sags
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 fixed
guide lines on the screen and the
actual distance/course on the road.
■When approaching three-dimensional objects
The distance guide lines are displayed according to flat surfaced objects (such
as the road). It is not possible to determine the position of three-dimensional
objects (such as vehicles) using the di stance guide lines. When approaching a
three-dimensional object that extends ou tward (such as the flatbed of a truck),
be careful of the following.
●Distance guidelines
Visually check the surroundings and
the area behind the vehicle. On the
screen, it appears that a truck is
parked at point . However, in real-
ity if you back up to point , you will
hit the truck. On the screen, it
appears that is closest and is
furthest away. However, in reality, the
distance to and is the same,
and is farther than and .

■Vehicle width guide lines
Visually check the surroundings and the area behind the vehicle. In the case
shown below, the truck appears to be outside of the vehicle width guide 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 vehicle width guide lines. In reality if you
back up as guided by the vehicle width guide lines, the vehicle may hit the
truck.

CAUTION
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist the driver
when backing up. When backing up, be sure to check visually behind and all around
the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in death or
serious injuries.
●Never depend on the rear view monitor system entirely when backing up. The image
and the position of the guide lines displaye d on the screen may differ from the actual
state.
Use caution, just as you would when backing up any vehicle.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic condi-
tions, road surface conditions, vehicle condit ion, etc. when parking. It is necessary to
be fully aware of this before using the rear view monitor system.
●When parking, be sure to check that the par king space will accommodate your vehi-
cle before maneuvering into it.
●Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the trunk lid is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check dire ct visually and with the mirrors all around
the vehicle before proceeding.
●If the tire sizes are changed, the position of the fixed guide lines displayed on the
screen may change.
●The camera uses a special lens. The distances between objects and pedestrians that
appear in the image displayed on the screen will differ from the actual distances.

NOTICE
■How to use the camera
●The rear view monitor system may not operate properly in the following 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.
• Do not strongly rub the camera lens. If th e camera lens is scratched, it cannot
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 vehi-
cle 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.
• When the camera is used under fluorescen t lights, sodium light or mercury light
etc., the lights and the illuminate d areas may appear to flicker.
●Do not expose the camera to strong impact as this could cause a malfunction. If this
happens, have the vehicle inspected by your Lexus dealer as soon as possible.
