843-6. Tips for operating the audio/visual system
Station interference: When a
reflected signal and a signal
received directly from a radio
station are very nearly the same
frequency, they can interfere
with each other, making it diffi-
cult to hear the broadcast.
Static: AM is easily affected by
external sources of electrical
noise, such as high tension
power lines, lightening or electri-
cal motors. This results in static.
■SiriusXM
 Cargo loaded on the roof lug-
gage carrier, especially metal
objects, may adversely affect
the reception of SiriusXM Sat-
ellite Radio.
 Alternation or modifications
carried out without appropri-
ate authorization may invali-
date the user’s right to
operate the equipment.
 This CD player is intended for
use with 12 cm discs only.
 Extremely high temperatures
can keep the CD player from
working. On hot days, use the
air conditioning system to cool
the inside of the vehicle
before using the player.
 Bumpy roads or other vibra-
tions may make the CD player
skip.
 If moisture gets into the CD player, the discs may not be
able to be played. Remove
the discs from the player and
wait until it dries.

1095-1. Rear view monitor system

Peripheral monitoring system
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.
