*
Fuel Sum = The accumulated fuel delivered since the last reset of this value
The DIC receives a GMLAN 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.
OIL LIFE
The engine control module (ECM) sends the oil life remaining percentage to the BCM via a GMLAN serial data message. The DIC receives a serial data
message from the BCM indicating the remaining oil life. The DIC displays the current percentage of the GM Oil Life System as determined by the ECM.
TRIP A and TRIP B
The DIC displays vehicle trip odometer mileage based on the vehicle speed signal (VSS) from the 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 INFO button on the DIC for 1 second in order to reset the trip odometer display.
RESET/SELECT
The RESET/SELECT button is used in order to acknowledge a warning message, reset an option, or to select an option. Press and hold for 0.25 seconds
to perform RESET/SELECT.

OIL-LIFE RESET
The engine control module (ECM) sends the oil life remaining percentage to the body control module (BCM) via a GMLAN serial data message. The
driver information center (DIC) receives a GMLAN serial data message from the BCM indicating the remaining oil life. The DIC displays the current
percentage of the GM Oil Life System as determined by the ECM. When the oil life remaining percentage drops below 10 percent, the DIC 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 RESET/SELECT button for 5 seconds until the DIC acknowledges.

Outside Air Temperature
The outside air temperature is read by the body control module (BCM) and transmitted over serial data to the instrument panel cluster (IPC) for display
in the driver information center (DIC). The BCM provides the logic for reading the outside air temperature sensor. The BCM sends the temperature to
the IPC in Celsius. The IPC is responsible for displaying the temperature and converting to Fahrenheit.
The sensor operates within a temperature range of -40°C to +60°C (-40°F to +140°F). The ambient air temperature sensor is mounted in the forward
engine area, behind the left front headlamp. This causes an air flow issue due to the sensor's location and can effect the ambient air update display
parameter in the DIC of the vehicle. For model year 2008 the ambient air temperature sensor will have a new location closer to the grill airflow. In the
present position, it is exposed to limited airflow from the grill before it reaches the radiator. The sensor signal varies between 0-5 volts.
The ambient air temperature sensor algorithm uses 3 pieces of information, outside air temperature data, vehicle speed, and time the engine was turned
off.
The ambient air temperature is updated and displayed by the DIC under the following conditions:
