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 sound is based on wave amplitude, so AM reception can
be disrupted by such things as lightning, power lines and
Because FM transmission is based on frequency variations,
interference that consists of amplitude variations can be
filtered out, leaving the reception relatively clear, which is the
major feature of FM radio.
The radio, steering wheel radio controls (if
equipped), and six-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.
