Vehicles without a smart key sys-
tem: The rear view image is dis-
played when the shift position is in
R and the power switch is in the
“ON” position.
Vehicles with a smart key system:
The rear view image is displayed
when the shift position is in R and
the power switch is in ON mode.
The rear view monitor system will
be deactivated when the shift lever
is in any position other than R.
Rear view monitor system
The rear view monitor system assists the driver by displaying
fixed guide line and an image o f the view behind the vehicle
while backing up, for example while parking.
For vehicles with a navigation system, refer to the “NAVIGATION
SYSTEM OWNER’S MANUAL”.
The screen illustrations used in this text are intended as exam ples,
and may differ from the image th at is actually displayed on the

Distance guide line
The line shows distance behind the vehicle, a point approximate ly 1.5 ft.
(0.5 m) (red) from the edge of the bumper.

The rear view monitor system
displays an image of the view
from the bumper of the rear
area of the vehicle.
To adjust the image on the rear
view monitor system screen.
(
 P. 292)
• The area displayed on the
screen may vary according to
vehicle orientation 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 disp layed
by the monitor.

Rear view monitor system camera
The camera for the rear view
monitor system is located
above the license plate.
● Using the camera
If dirt or foreign matter (such as water droplets, snow, mud et c.) is
adhering to the camera, it cannot transmit a clear image. In th is
case, flush it with a large quantity of water and wipe the came ra
lens clean with a soft and wet cloth.
■Differences between the scr een and the actual road
The distance guide lines and the vehicle width guide lines may not
actually be parallel with the div iding 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 lef t
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 sur-
faces. In any of the following situations, there is a margin of error
between the fixed guide lines on the screen and the actual dis-
tance/course on the road.

●When the ground behind the vehicle slopes up sharply
The distance guide lines will
appear to be closer to the vehi-
cle 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 ve hicle slopes down sharply
The distance guide lines will
appear to be farther from the
vehicle than the actual dis-
tance. 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.

2604-6. Using the driving support systems
PRIUS c_U
●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 fixed guide
lines on the screen and the
actual distance/course on the
road.
■When approaching thre e-dimensional objects
The distance guide lines are displayed according to flat surfac ed
objects (such as the road). It i s not possible to determine the posi-
tion of three-dimensional objects (such as vehicles) using the dis-
tance guide lines. When approaching a three-dimensional object
that extends outward (such as t he flatbed of a truck), be careful of
the following.
● Distance guidelines
Visually check the surroundings
and the area behind the vehi-
cle. On the screen, it appears
that a truck is parked 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 distance to
and is the same, and is
farther than and .
