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:On vehicles so equipped the radio, steering
wheel radio controls and 6 disc CD/DVD changer will
remain active for up to 45 seconds after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

REMOTE SOUND SYSTEM CONTROLS — 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
push-button in the center and controls the volume and
mode of the sound system. Pressing the top of the rockerswitch will increase the volume and pressing the bottom
of the rocker switch will decrease the volume.
Pressing the center button will make the radio switch
between the various modes available (AM/FM/TAPE/
CD, Etc.).
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 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 preset station that you have pro-
grammed in the radio preset push-button.

RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance 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 “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Climate Controls — Manual
Air Conditioning
The controls for the heating/air conditioning and venti-
lation system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.The instrument panel features four dual-vane airflow
registers. Two registers are located on the outer ends of
the instrument panel and two are located in the center of
the instrument panel. These registers can be closed to
partially block airflow.
