●When the ground behind the vehicle slopes up sharply
The distance guide lines will
appear to be closer to the
vehicle than the actual dis-
tance. Because of this, objects
will appear to be farther away
than they actually are. In the
same way, there will be a mar-
gin of error between the
guidelines and the actual dis-
tance/course on the road.

●When any part of the vehicle 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 fixation
guide lines on the screen and
the actual distance/course on
the road.
■When approaching three-dimensional objects
The distance guide lines are disp layed 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-dime nsional object that extends out-
ward (such as the flatbed of a tru ck), be careful of the following.
●Distance guidelines
Visually check the surround-
ings and the area behind the
vehicle. On the screen, it
appears that a truck is parking
at point . However, in reality
if you back up to point , you
will hit the truck. On the
screen, it appears that is
closest and is farthest away.
However, in reality, the dis-
tance to and is the
same, and is farther than
and .

■Vehicle width extension 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
extension 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 extension guide lines. In reality if you back up as guided by the
vehicle width extension 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 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 guidelines.
When and how much to turn the steering wheel will vary according to traffic con-
ditions, road surface conditions, vehicle condition, etc. when parking. It is neces-
sary 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
vehicle 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 direct visually and with the mirrors
all around the vehicle before proceeding.
●If the tire sizes are changed, the position of the fixation guide lines displayed on
the screen may change.
●The camera uses a special lens. The di stances between objects and pedestrians
that appear in the image displayed on th e screen will differ from the actual dis-
tances. ( P. 2 5 6 )

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 cameramay 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 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
vehicle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the cam- era or camera area. Doing so may result in the camera malfunctioning.
• When the camera is used under fluorescent 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 possi-
ble.
