■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 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 extension 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 extension 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 dist ance guide for flat road surfaces. In
any of the following situations, th ere is a margin of error between the
fixation 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 fixation guide lines
on the screen and the actual dis-
tance/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-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 surroundings
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.

■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
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.
●The rear view monitor system is a supplemental device intended to assist the
driver when backing up. Never depend on the rear view monitor system entirely
when backing up. Always make sure your intended path is clear.
Use caution, just as you would when backing up any vehicle.
●Never back up while looking only at the screen.
The image shown on the screen may differ from the actual state, and you could
collide with another vehicle or obstacles if backing up looking only at the screen,
possibly causing an accident. When backing up, be sure to check in front of and
behind the vehicle, both directly and with mirrors.
●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 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 mirror 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 4 )
