6. TIPS FOR OPERATING THE AUDIO SYSTEM
PRIUS PRIME_Navi_OM47C85U_(U)
19.03.07 12:34
Fading: AM broadcasts are reflected by
the upper atmosphere — especially at
night. These reflected signals can interfere
with those received directly from the radio
station, causing the radio station to sound
alternately strong and weak.
Station interference: When a reflected sig-
nal and a signal received directly from a ra-
dio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static: AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening or electrical
motors. This results in static.
Cargo loaded on the roof luggage carrier,
especially metal objects, may adversely
affect the reception of XM Satellite Radio.
 Alternation or modifications carried out
without appropriate authorization may
invalidate the user’s right to operate the
equipment. 

PERIPHERAL MONITORING SYSTEM
6
THE CAMERA
The camera for the rear view monitor
system is located as shown in the illus-
tration.
USING THE CAMERA
If dirt or foreign matter (such as water
droplets, snow, mud etc.) is adhering
to the camera, it cannot transmit a
clear image. In this case, flush it with a
large quantity of water and wipe the
camera lens clean with a soft and wet
cloth.
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 con-
struction, 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 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 malfunctioning.
● 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.

shown in the following cases:
• When driving on a small angled Y-
shaped road.
• When driving on a winding road.
