Operating Tips for Audio
System
WARNING
Do not adjust the audio control
switches while driving the vehicle:
Adjusting the audio while driving the
vehicle is dangerous as it could
distract your attention from the
vehicle operation which could lead to
a serious accident. Always adjust the
audio while the vehicle is stopped.
Even if the audio control switches are
equipped on the steering wheel, learn
to use the switches without looking
down at them so that you can keep
your maximum attention on the road
while driving the vehicle.
CAUTION
For the purposes of safe driving,
adjust the audio volume to a level
that allows you to hear sounds
outside of the vehicle.
NOTE
Do not use the audio for long periods of
l
time while the engine is off. Otherwise the
battery could go dead.
If a cellular phone or CB radio is used in
l
or near the vehicle, it could cause noise to
occur from the audio system, however, this
does not indicate that the system has been
damaged.

qRadio 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.
