Area displayed on screen
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. 329)
• 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 dis-
played 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 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

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
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 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 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 distance guide
lines. When approaching a three-dimensional object that extends out-
ward (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 . How-
ever, in reality if you back up to
point , you will hit the truck.
On the screen, it appears that

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. How-
ever, 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 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
conditions, road surface conditions, vehicle condition, 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
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
• 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 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.
