The radio displays driver information center (DIC) information when it first
powers up. The uplevel radio shows the time and outside temperature on the first line
of the display, and DIC information on the second line of the display.
There are 3 DIC buttons on the radio.
ENTER
The ENTER button is used in order to acknowledge a warning message, reset an
option, or to select an option.
INFO
The INFO button is used in order to navigate through the following driver information
center (DIC) information modes:
AV SPEED
Average speed is calculated using the equation: Average Speed = Distance/Ignition
On
| • | Distance = The accumulated distance travelled since the last reset of
this value |
| • | Ignition On = The accumulated ignition on time since the last reset of
this value |
Ignition on time is measured from the time that the ignition is turned ON to
the time when the ignition is turned OFF. The value of this mode is retained during
ignition OFF. Press and hold the ENTER button on the radio for one second in order
to reset the average speed display.
ECON
Average fuel economy is calculated using the equation: AFE = Distance/Fuel
| • | Distance = The accumulated distance travelled since the last reset of
this value |
| • | Fuel = The accumulated fuel consumption since the last reset of this value |
The instrument panel cluster (IPC) receives a serial data message from the body
control module (BCM) regarding fuel usage information. The value of this mode is retained
during ignition OFF and can be changed between English units and metric units. Press
and hold the ENTER button on the radio switch for one second in order to reset the
ECON display.
FUEL RANGE
This message indicates the estimated distance that the vehicle can travel under
the current fuel economy and fuel level conditions since the last reset of the value.
Fuel Range is calculated using the equation: Fuel Range = Distance Sum/Fuel Sum.
| • | Distance Sum = The accumulated distance travelled since the last reset
of this value. |
| • | Fuel Sum = The accumulated fuel delivered since the last reset of this
value |
The radio receives a serial data message from the BCM with fuel information.
The value of this mode is retained during ignition OFF and can be changed between
English units and metric units. The FUEL RANGE display cannot be reset.
ENGINE OIL LIFE
The powertrain control module (PCM) or the engine control module (ECM) sends
the engine oil life remaining percentage to the body control module (BCM) via a GMLAN
serial data message. The radio receives a serial data message from the BCM indicating
the remaining oil life. The radio displays the current percentage of the GM Oil Life
System as determined by the PCM/ECM.
TRIP A and TRIP B
The radio determines vehicle trip odometer mileage based on the vehicle speed
signal (VSS) from the body control module (BCM). The trip odometer displays accumulated
km (mi) since the last reset of this value. The trip odometer is capable of displaying
up to 999.9 km (999.9 mi). Trip odometer information is not retained
when the battery is disconnected. Press and hold the ENTER button on the radio for
one second in order to reset the trip odometer display.
MENU
The MENU button is used in order to navigate through the following personalization
modes:
ENGINE OIL-LIFE RESET
The powertrain control module (PCM) or the engine control module (ECM) sends
the oil life remaining percentage to the body control module (BCM) via a GMLAN serial
data message. The radio receives a serial data message from the BCM indicating the
remaining oil life. The radio displays the current percentage of the GM Oil Life System
as determined by the PCM/ECM. When the oil life remaining percentage drops below 10
percent, the radio displays CHANGE ENGINE OIL. When the engine oil is changed, reset
the engine oil life in order to clear the oil life remaining percentage display. Press
and hold the ENTER button for 5 seconds until the radio displays ACKNOWLEDGED.

Personalization Description and Operation
.
Outside Air Temperature
The body control module (BCM) reads the outside air temperature sensor. The
temperature sensor is a 2-wire negative temperature co-efficient thermistor. The BCM
provides 5 volts to an internal input resistor that is connected to the outside
air temperature sensor. The outside air temperature is displayed in the driver information
center (DIC) and the DIC is located in the radio. The temperature information is transmitted
by the BCM for display in the DIC via GMLAN serial data message. The BCM provides
the outside air temperature information in Celsius. The radio converts the temperature
to Fahrenheit, if required.
