■Differences between the screen and the actual road
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 following situations, there is a margin of error between the fixation 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
guide lines and the actual dis-
tance/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 guide lines 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 fixation 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 distance guide lines. When approaching a
three-dimensional object that extends outward (such as the flatbed of a truck),
be careful of the following.
●Vehicle width guide lines
Visually check the surroundings
and the area behind the vehicle.
In the case shown in the illustra-
tion, the truck appears to be out-
side of the vehicle width guide
lines and the vehicle does not
look as if it hits the truck. How-
ever, the rear body of the truck
may actually cross over the vehi-
cle width guide lines. In reality if
you back up as guided by the
vehicle width guide lines, the
vehicle may hit the truck.

Likely causeSolution
‰ The image is difficult to see
• The vehicle is in a dark area
• The temperature around the lens is
either high or low
• The outside temperature is low

• It is raining or humid
• Foreign matter (mud etc.) is adhering to the camera
• There are scratches on the camera
• Sunlight or headlights are shining directly into the camera
• The vehicle is under fluorescent lights, sodium lights, mercury lights etc.
If this happens due to these causes, it
does not indicate a malfunction.
Back up while visually checking the vehi-
cle’s surroundings. (Use the monitor
again once conditions have been
improved.)
‰ The image is blurry
Dirt or foreign matter (such as water
droplets, snow, mud etc.) is adhering to
the camera.Rinse the camera lens with water and
wipe it clean with a soft cloth.
Wash with a mild soap if the dirt is stub-
born.

■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 displayed 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 guide lines.
When and how much to turn the steering wh eel 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 parking 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 emergency tires
• When the back door 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 direct 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 scre en 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 maychange.
• 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 the 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 illuminated 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.
