Vehicle center guide line
The line indicates the estimated vehicle center on the ground.
Vehicle width guide line
The line indicates a guide path when the vehicle is being backed straight up.
The displayed width is wider than the actual vehicle width.
The line aligns with the estimated course lines when the steering wheel is straight.
Estimated course lines
The lines show an estimated course when the steering wheel is turned.
Distance guide line
The line moves, together with the estimated course lines, in sync with the steering
wheel. The line shows points approximately 1.5 ft. (0.5 m) (red) and approximately
3 ft. (1 m) (yellow) from the center of the edge of the bumper.
Distance guide line
The line shows distance behind the vehicle, a point approximately 1.5 ft. (0.5 m)
(blue) from the edge of the bumper.

are within the left and right divid-
ing lines of the parking space. Vehicle width guide line

when parking.

■Area displayed on screen
The parking assist monitor displays
an image of the view from the
bumper of the rear area of the vehi-
cle.
The image on the rear view monitor
system screen can be adjusted.
( → P. 2 8 0 )
• The area displayed on the screen
may vary according to vehicle orien-
tation conditions.
• Objects which are close to either corner of the bumper or under the
bumper cannot be seen on the
screen.
• The camera uses a special lens. The
distance of the image that appears
on the screen differs from the actual
distance.
• Items which are located higher than the camera may not be displayed on
the monitor.
• If your vehicle is equipped with a backlit license plate, it may interfere with the dis- play.

■Lexus parking assist monitor camera
The camera for the parking assist
monitor 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 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 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 guide lines on
the screen and the actual distance/course on the road.

IS350/250_U (OM53C50U)
●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 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 object (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 in the illustra-
tion, the truck appears to be out-
side of the estimated course lines
and the vehicle does not look as if
it will hits the truck. However, the
rear body of the truck may actu-
ally 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.
