SYSTEM OWNER’S MANUAL”.The screen illustrations used in this text are intended as examples,
and may differ from the image that is actually displayed on the

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 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 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 vehicle slopes down sharply
The distance guide lines will
appear to be further 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.

●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 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 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 the 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 furthest away. However,
in reality, the distance to
and is the same, and is
farther than and .

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 vehi-
cle width 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 guide lines. In reality if you back up as guided by
the vehicle width guide lines, the vehicle may hit the truck.

WARNING
■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 visually check all
around the vehicle both directly and using the mirrors before proceeding. If
you do not, you may hit another vehicle, and could possibly cause an acci-
dent.
Pay attention to the following precauti ons when using the rear view monitor
system.
● 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 traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. 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 or the compact spare tire
• 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 visually check
all around the vehicle both directly and using the mirrors before proceed-
ing.
● 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. ( P. 225)
