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 follow-
ing situations, there is a mar-
gin of error between the 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 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 guide lines
and the actual distance/course
on the road.
NOTICE
●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, disassemble 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 camera
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 a
glass coating to adhere to the
camera. If this happens, wipe it
off as soon as possible.
• If the temperature changes rap- idly, 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 malfunctioning.
●Do not expose the camera to
strong impact as this could
cause a malfunction. If this hap-
pens, have the vehicle
inspected by your Toyota dealer
as soon as possible.

cle 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 dis-
tance/course on the road.

Peripheral monitoring system
The distance guide lines are dis-
played 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 vehicle width guide lines and
distance guide lines. When
approaching a three-dimen-
sional object that extends out-
ward (such as the flatbed of a
truck), be careful of the follow-
ing.
■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. 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. Vehicle width guide lines

●The screen illustrations used in
this text are intended as exam-
ples, and may differ from the
image that is actually displayed on
the screen.

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 accident.

Toyota parking assist
monitor*
The parking assist monitor
assists the driver by dis-
playing an image of the view
behind the vehicle while
backing up, for example
while parking.
When the display is
changed to the wide rear
view mode, a wider lateral
view behind the vehicle will
be displayed.
Driving precautions

●Never depend on the parking
assist monitor entirely when
backing up. The image and the
position of the guide lines dis-
played on the screen may differ
from the actual state.

when backing up any vehicle.
●Be sure to back up slowly,
depressing the brake pedal to
control vehicle speed.
●If you seem likely to hit nearby
vehicles, obstacles, people or
mount the shoulder, depress
the brake pedal to stop the vehi-
cle.
●The instructions given are only
guidelines. When and how
much to turn the steering wheel
will vary according to traffic con-
ditions, road surface condi-
tions, vehicle condition, etc.
when parking. It is necessary to
be fully aware o f this before
using the parking assist system.
●When parking, be sure to check
that the parking space will
accommodate your vehicle
before maneuvering into it.
●Do not use the parking assist
monitor in the f ollowing cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emer- gency tires
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or
