NOTE:If you try to remove the key before you place the
lever in PARK, the key may become trapped temporarily
in the ignition cylinder. If this occurs, rotate the key to the
right slightly, then remove the key as described. If a
malfunction occurs, the system will trap the key in the
ignition cylinder to warn you that this safety feature is
inoperable. The engine can be started and stopped but
the key cannot be removed until you obtain service.
NOTE:For vehicles not equipped with the Electronic
Vehicle Information Center (EVIC), the power window
switches, radio, hands–free system (if equipped), and
power outlets will remain active for 10 minutes after the
ignition switch is turned off. Opening either front door
will cancel this feature.
For vehicles equipped with the Electronic Vehicle Infor-
mation Center (EVIC), the power window switches,
radio, hands–free system (if equipped), and power out-
lets will remain active for up to 10 minutes after theignition switch is turned off. Opening either front door
will cancel this feature. The time for this feature is
programmable. For details, refer to “KEY OFF POWER
DELAY > OFF” under “Personal Settings (Customer
Programmable Features),” under “Electronic Vehicle In-
formation Center (EVIC)” in Section 3 of this manual.
WARNING!
Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Don’t leave the keys in the
ignition. A child could operate power windows,
other controls, or move the vehicle.

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.
