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: For vehicles not equipped with the Electronic
Vehicle Information Center (EVIC), the radio, steering
wheel radio controls (if equipped), and 6 disc CD/DVD
changer (if equipped) will remain active for 10 minutes
after the ignition switch is turned off. Opening either
front door will cancel this feature.
NOTE: For vehicles equipped with the Electronic Ve-
hicle Information Center (EVIC), the radio, steering
wheel radio controls (if equipped), and 6 disc CD/DVD
changer (if equipped) will remain active for up to 60
minutes after the ignition switch is turned off. Opening
either front door will cancel this feature. The time is
programmable. For details, refer to "Delay Power Off to
Accessories Until Exit," under "Personal Settings (Cus-
tomer Programmable Features)," under "Electronic Ve-
hicle Information Center (EVIC)" in Section 4 of this
manual.
