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 furthest away. However,

in reality, the distance to

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.

• The temperature around the lens

is either high or low

• The outside temperature is low
• There are water droplets on the

camera

adhering to the camera

• There are scratches on the cam-

era

• Sunlight or headlights are shining

directly into the camera

• The vehicle is under fluorescent

lights, sodium lights, mercury
lights etc.

If this happens due to these causes,

• The vehicle is tilted (there is a

heavy load on the vehicle, tire
pressure is low due to a tire punc-
ture, etc.)

• The vehicle is used on an incline.

If this happens due to these causes,

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 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 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.

WARNING

●

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. (

→P. 310)

NOTICE

■

How to use the camera

●

The rear view monitor system may not operate properly in the following
cases.

• If the back of the vehicle is hit, the position and mounting angle of the

camera may change.

• As the camera has a water proof construction, do not detach, disassem-

ble or modify it. This may cause incorrect operation.

• When cleaning the camera lens, flush the camera with a large quantity

of water and wipe it with a soft and wet cloth. Strongly rubbing the cam-
era lens may cause the camera lens to be scratched and unable to
transmit a clear image.

• Do not allow organic solvent, car wax, window cleaner or glass coat to

adhere to the camera. If this happens, wipe it off as soon as possible.

• If the temperature changes rapidly, such as when hot water is poured

on the vehicle in cold weather, the system may not operate normally.

• When washing the vehicle, do not apply intensive bursts of water to the

camera or camera area. Doing so may result in the camera malfunc-
tioning.

• When the camera is used under fluorescent lights, sodium light or mer-

cury light etc., the lights and the illuminated areas may appear to flicker.

●

Do not expose the camera to strong impact as this could cause a malfunc-
tion. If this happens, have the vehicle inspected by your Toyota dealer as
soon as possible.
