NOTE:Magnetic materials should be kept away from
the top of the instrument panel above the radio. This is
where the compass sensor is located.
Automatic Compass Calibration
The self-calibrating feature of the compass eliminates the
need to calibrate the compass for normal conditions.
During a short initial period, the compass may appear
erratic and the CAL symbol will appear (blinking) on the
display. After the vehicle has completed at least one
complete circle under 5 mph (8 km/h) in an area free
from large metal objects, calibration will be complete
when the CAL symbol is extinguished.
After initial calibration, the compass will continue to
automatically update this calibration whenever the ve-
hicle is in motion.
Manual Compass Calibration
NOTE: Before attempting a manual compass calibra-
tion, the engine must be running and the transmission
in the PARK position (if equipped).
If the compass seems in error or erratic, you may wish to
manually recalibrate the compass. To manually calibrate
the compass, you must first enter the variance mode.
Press and hold the left button (located on the instrument
cluster) for approximately 10 seconds to enter the vari-
ance mode, and release the button when the VAR (Com-
pass Variance) symbol appears. The current variance
value will also be displayed. Once in the variance mode,
it is necessary to release the button, and then press and
hold it again (approximately 10 seconds) until CAL is
displayed (solid, not blinking). Manual compass calibra-
tion has been initiated. Drive the vehicle slowly in one or
more circles under 5 mph (8 km/h) in an area free from
large metal objects until the CAL symbol is extinguished.

Outside Temperature
If the outside temperature is more than 131°F (55°C), the
display will show 131°F (55°C). When the outside tem-
perature is less than40°F (40°C), the display will
show 40°F (40°C).
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.

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 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.

NOTE: The ignition switch must be in the ON or ACC
position to operate the radio.
Power Switch/Volume Control (Rotary)
Push the ON/VOLUME control knob to turn on the
radio. Push the ON/VOLUME control knob 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
ON/VOLUME control knob 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.
SEEK Buttons
Press and release the SEEK buttons to search for the next
listenable station in AM/FM mode. Press the right switch

to seek up and the left switch to seek down. The radio
will remain tuned to the new station until you make
another selection. Holding either button will bypass
stations without stopping until you release it.
SCAN Button
Pressing the SCAN button causes the tuner to search for
the next listenable station in AM or FM frequencies,
pausing for five seconds at each listenable station before
continuing to the next. To stop the search, press the
SCAN button a second time.
Voice Recognition System (Radio) — If Equipped
Refer to “Voice Recognition System (VR)” in Section 3.
Voice Recognition Button (UConnectHands-Free
Phone) — If Equipped
Press this button to operate the Hands-Free Phone
(UConnect) feature (if equipped). Refer to “Hands-Free
Communication (UConnect)” in Section 3. If your vehicle is not equipped with or this feature is not
available on your vehicle, a “Not Equipped With
UConnect” message will display on the radio screen.
Phone Button (UConnect
Hands-Free Phone) — If
Equipped
Press this button to operate the Hands-Free Phone
(UConnect) feature (if equipped). Refer to “Hands-Free
Communication (UConnect)” in Section 3.
If your vehicle is not equipped with or this feature is not
available on your vehicle, a “Not Equipped With
UConnect” message will display on the radio screen.
TIME Button
Press the TIME button and the time of day will display. In
AM or FM mode, pressing the TIME button will switch
between the time and frequency displays.

SCROLL control knob.
3. After adjusting the hours, press the right side TUNE/
SCROLL control knob to set the minutes. The minutes
will begin to blink.
4. Adjust the minutes using the right side TUNE/
SCROLL control knob. Press the TUNE/SCROLL control
knob to save time change.
5. To exit, press any button/knob or wait five seconds.
