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 time for this feature is pro-
grammable. Refer to ªPersonal Settings (Customer Pro-

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.

REMOTE SOUND SYSTEM CONTROLS Ð IF
EQUIPPED
The remote sound system controls are located on the rear
surface of the steering wheel. Reach behind the wheel to
access the switches.The right-hand control is a rocker type switch with a
button in the center. Pressing the top of the switch will
increase the volume and pressing the bottom of the
switch will decrease the volume. The center button of the
right-hand control will allow you to change the mode.
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 left side 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 pre-set station that you have
programmed in the radio pre-set push-buttons.

NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged, oversized, or have theft
protection encoding. Try a known good disc before
considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily ªclearº by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of a series of rotary knobs. These comfort
controls can be set to obtain desired interior conditions.
