Compass Variance
Compass Variance is the difference between magnetic
North and geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. In order to ensure compass accuracy, the Com-
pass Variance should be set to the zone number on the
Compass Variance map that corresponds to the current
location of the vehicle.
NOTE:Magnetic materials should be kept away from
the Instrument Panel. This is where the compass sensor is
located.

To Set the VarianceWith the ignition in the ON position,
quickly (less than one second) press and release the EVIC
button several times until you have displayed the Per-
sonal Settings (Customer-Programmable Features) menu.
Once in the Personal Settings (Customer-Programmable
Features) menu, press and release (less than one second)
the EVIC button several times until “Compass Variance”
is highlighted. The “Compass Variance” message and the
current variance zone number will be displayed. To
change the zone, press and hold (longer than two sec-
onds) the EVIC button to increment the variance one
step. Repeat as necessary, with individual long (for at
least 1 second) EVIC button presses for each increment,
until the desired variance is achieved. To exit the Vari-
ance Programming, press the EVIC button with a short
(less than one second) button press.
NOTE:The factory default is Zone 8. During program-
ming, the zone value will wrap around from Zone 15 to
Zone 1.Compass Calibration
The Compass will automatically calibrate if the Cal
indicator is flashing, by driving around slowly (under 5
mph/8 km/h) in one or more complete circles in an area
free from large metallic objects or power lines, until the
Cal indicator turns off. If during normal use the compass
appears erratic, inaccurate or abnormal, you may wish to
manually calibrate the compass. Prior to calibrating the
compass make sure the proper zone is selected.
To Manually Calibrate the CompassStart the engine and
leave the transmission in the PARK position. Using a
short button press (less than one second), press and
release the EVIC button several times until the EVIC
displays the Personal Settings (Customer Programmable
Features) menu. Once in the Personal Settings
(Customer-Programmable Features) menu, press and re-
lease (less than one second) the EVIC button several
times until “Calibrate Compass (Yes)” is displayed. Using
a long button press (more than one second), pressing the
192 UNDERSTANDING YOUR INSTRUMENT PANEL

EVIC button will place the Compass in calibration mode.
The Cal indicator will come on continuously in the EVIC
display, to indicate that the compass is now in the
calibration mode and that the vehicle can now be driven
to calibrate. A short EVIC button press from theCali-
brate Compass (Yes)screen will exit the EVIC Customer
Programmable features, and return it to its normal oper-
ating mode. To complete the compass calibration, drive
the vehicle in one or more complete 360 degree circles
under 5 mph (8 km/h) in an area free from power lines
and large metallic objects, until the CAL indicator turns
off. The compass will now function normally.RADIO GENERAL INFORMATION
RADIO BROADCAST SIGNALS
The radio will provide excellent reception under most
operating conditions. Like any system, however, automo-
tive radios have performance limitations, due to mobile
operation and natural phenomena, which might lead you
to believe your sound system is malfunctioning. To help
you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
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.

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.
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 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.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the frequency and/or
time in hours and minutes (depending on your radio
model), whenever the ignition switch is in the ON or
ACC position.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, timekeeping is
accurately maintained.
On the AM/FM/CD (6-disc) radio, the time button
alternates the location of the time and frequency on the
display. On the AM/FM/CD (single-disc) radio, only one
of the two, time or frequency, is displayed.

Clock Setting Procedure
1. Press and hold the TIME button until the hours blink.
2. Adjust the hours by turning the TUNE/AUDIO con-
trol knob.
3. After the hours are adjusted, push the TUNE/AUDIO
control knob to set the minutes.
4. Adjust the minutes by turning the TUNE/AUDIO
control knob.
5. To exit, press any button/knob, or wait approximately
five seconds.

Operating Instructions - Radio Mode
NOTE:The ignition switch must be in the ON or ACC
position to operate the radio.
Power Switch/Volume Control (Rotary)
Press the ON/VOL control to turn the radio ON. Press
the ON/VOL a second time to turn OFF the radio.
Electronic Volume Control
The electronic volume control turns continuously (360
degrees) in either direction without stopping. Turning the
volume control to the right increases the volume and to
the left decreases it.
When the audio system is turned on, the sound will be
set at the same volume level as last played.
For your convenience, the volume can be turned down,
but not up, when the audio system is off and the ignition
is ON.
Mode Button (Radio Mode)
Press the MODE button repeatedly to select between the
CD player and Satellite Radio (if equipped).
SEEK Button (Radio Mode)
Press and release the SEEK button to search for the next
listenable station in either AM/FM or Satellite (if
equipped) mode. Press the right side of the button to seek
up and the left side to seek down. The radio will remain
tuned to the new station until you make another selec-
tion. Holding the button will bypass stations without
stopping until you release it.
MUTE Button (Radio Mode)
Press the MUTE button to cancel the sound from the
speakers. MUTE will display. Press the MUTE button a
second time and the sound from the speakers will return.
Rotating the volume control, turning the radio ON/OFF,
or turning ON/OFF the ignition, will cancel the MUTE
feature.
