UNDERSTANDING YOUR INSTRUMENT PANEL
Two Types of Signals
FM Reception
There are two basic typ es of rad io signals... AM or
Amplitude Mod ulation, in which the transm itted sou nd
causes the amplitude, or height, of the rad io waves to
vary... and FM or Frequ ency Mod ulation, in which the
frequ ency of the wave is varied to carry the sou nd .
Because FM transm ission is based on frequ ency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the recep tion relatively clear,
which is the major featu re of FM rad io.
NOTE:
On vehicles so equ ipped the rad io, steering
Electrical Disturbances
wheel rad io controls and 6 disc CD/ DVD changer will
rem ain active for up to 45 second s after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this featu re.
Radio waves may pick up electrical distu rbances during
transm ission. They mainly affect the wave amplitude,
and thu s rem ain a part of the AM recep tion. They
interfere very little with the frequ ency variations that
carry the FM signal.

AM Reception
AM sou nd is based on wave amplitude, so AM recep tion
can be disru pted by such things as lightning, power lines
and neon signs.

side of you r rad io facep late.
