Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

The right hand control is a rocker type switch with a
push-button in the center and controls the volume and
mode of the sound system. Pressing the top of the rocker
switch will increase the volume and pressing the bottom
of the rocker switch will decrease the volume.
Pressing the center button will make the radio switch
between the various modes available (AM/FM/TAPE/
CD, Etc.).
The left hand control is a rocker type switch with a
push-button in the center. The function of the left hand
control is different depending on which mode you are in.
The following describes the left hand control operation in
each mode.Radio Operation
Pressing the top of the switch will “Seek” up for the next
listenable station and pressing the bottom of the switch
will “Seek” down for the next listenable station.
The button located in the center of the left hand control
will tune to the next preset station that you have pro-
grammed in the radio preset push-button.
CD Player
Pressing the top of the switch once will go to the next
track on the CD. Pressing the bottom of the switch once
will go to the beginning of the current track or to the
beginning of the previous track if it is within one second
after the current track begins to play.
If you press the switch up or down twice it plays the
second track, three times, it will play the third, etc.
