nRadio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere. Therefore, they can reach
longer distances than FM signals. Because
of this, two stations may sometimes be
picked up on the same frequency at the
same time.
FM characteristics
An FM broadcast range is usually about 40–
50 km (25–30 miles) from the source.
Because of extra coding needed to break the
sound into two channels, stereo FM has
even less range than monaural (non-stereo)
FM. Signals from an FM transmitter are similar to
beams of light because they do not bend
around corners, but they do reflect.
Unlike AM signals, FM signals cannot travel
beyond the horizon. Therefore, FM stations
cannot be received at the great distances
possible with AM reception.
Atmospheric conditions can also affect FM
reception. High humidity will cause poor
reception. However, cloudy days may pro-
vide better reception than clear days.
Multipath noise
Since FM signals can be reflected by
obstructions, it is possible to receive both the
direct signal and the reflected signal at the
same time. This causes a slight delay in
reception and may be heard as a broken
sound or a distortion. This problem may also
be encountered when in close proximity to
the transmitter.

Rear View Monitor
Switching to the Rear View Monitor Display
Shift the shift lever to R with the ignition switch in the ON position to switch the display to the
rear view monitor display.
Note
When the shift lever is shifted from R to another shift lever position, the screen returns to the
previous display.
Displayable Range on the Screen
The images on the screen may be different from the actual conditions.
Note
lThe displayable range varies depending on the vehicle and road conditions.
l The displayable range is limited. Objects under the bumper or around the bumper ends
cannot be displayed.
l The distance appearing in the displayed image is different from the actual distance because
the rear view parking camera is equipped with a specific lens.
l Some optionally installed vehicle accessories may be picked up by the camera. Do not
install any optional parts that can interfere with the camera view, such as illuminating parts
or parts made of reflective material.
l It may be difficult to see the display under the following conditions, however, it does not
indicate a malfunction.
• In darkened areas.
• When the temperature around the lens is high/low.
• When the camera is wet such as on a rainy day or during periods of high humidity.
• When foreign material such as mud is stuck around the camera.
• When the camera lens reflects sunlight or headlight beams.
l If the camera picks up a high-intensity light such as sunlight reflected off the vehicle body, a
bright belt (light line) may appear on the display. (Smear phenomenon)
