Additional Vehicle Information Displays: If the vehicle is an STS-V, the DIC also has additional vehicle information displays which include the following:
| • | Transmission Fluid Temperature |
Average Fuel Economy
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 ECM sends the average fuel economy serial data message to the IPM. The instrument panel cluster (IPC) receives a serial data message from the instrument panel module (IPM) regarding fuel usage information. The value of this mode is retained during
ignition OFF and can be changed between English units and metric units by pressing the English/Metric button on the DIC switch. Press and hold the Info button on the driver information center (DIC) switch for 1 second in order to reset the AFE display.
Average 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 Reset button on the DIC switch for 1 second in order
to reset the average speed display.
Battery Voltage
The instrument panel cluster (IPC) receives a serial data message from the instrument panel module (IPM) for battery voltage data. The gage on the IPC displays similar battery voltage values. When the battery voltage is below the normal operating range,
the DIC displays LOW and the actual battery voltage. When the battery voltage is greater than the normal operating range, the driver information center (DIC) displays HIGH and the actual battery voltage. The charging system indicator also illuminates when the
battery voltage is outside the normal operating range.
Engine Oil Life Remaining
The engine control module (ECM) sends the oil life remaining percentage to the instrument panel module (IPM) via the serial data circuit. The instrument panel cluster receives a serial data message from the IPM indicating the engine oil life remaining.
The driver information center (DIC) displays the current percentage of the GM Oil Life System as determined by the ECM. When the oil life remaining percentage drops below 5 percent, the DIC displays CHANGE ENGINE OIL SOON. When the engine oil is changed,
reset the GM Oil Life System. Press and hold the RESET button on the DIC switch for at least 3 seconds until the DIC displays 100 percent.
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 battery connection to the IPC. 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 ECM sends the fuel range value to the instrument panel module (IPM). The instrument panel cluster (IPC) receives a serial data message from the instrument panel module (IPM) with fuel information. The fuel range value is retained during ignition OFF
and can be changed between English and Metric units by pressing the English/Metric button on the driver information center (DIC) switch. The Fuel Range display cannot be reset. Whenever the calculated fuel range is less than 64 Km/h (39.8 miles)
RANGE-LOW is displayed.
Fuel Used
The instrument panel cluster (IPC) calculates and displays the total amount of fuel used since the last reset of the value.
The engine control module (ECM) sends the fuel used value to the instrument panel module (IPM) via the serial data circuit. The IPC receives a serial data message from the instrument panel module (IPM) with fuel information. The fuel used value is retained
during ignition OFF and can be changed between English and Metric units by pressing the English/Metric button on the driver information center (DIC) switch. Press and hold the RESET button on the DIC switch for one second in order to reset the Fuel Used display.
Instantaneous Fuel Economy (IFE)
Instantaneous fuel economy (IFE) is calculated using the equation: IFE = Distance/Fuel.
| • | Distance = The accumulated distance travelled for the last 2 seconds |
| • | Fuel = The accumulated fuel delivered for the last 2 seconds |
The instrument panel cluster (IPC) receives a serial data message from the instrument panel module (IPM) with fuel information. The distance information is calculated by the IPC using the vehicle speed information from the ECM. These values are retained
during ignition OFF and can be changed between English and Metric units by pressing the English/Metric button on the driver information center (DIC) switch. The IFE display cannot be reset.
Timer
The timer records elapsed time starting from activation. When the driver information center (DIC) displays the timer, pressing the INFO RESET button for 1.0 seconds on the DIC resets the timer. Pressing the INFO RESET button on the DIC switch for
approximately 1.0 seconds starts and stops the timer. The DIC displays the timer in one of the following formats:
The first XX represents hours elapsed, the second XX represents minutes elapsed, and the third XX represents seconds elapsed. The ON or OFF indicates whether the timer is currently running. The maximum range of the timer is 99 hours, 59 minutes,
and 59 seconds. After the maximum range is reached, the timer displays all zeros (00:00:00).
Tire Pressure Monitor
The instrument panel cluster (IPC) receives a serial data message from the tire pressure monitoring (TPM) system for front and rear tire pressure data. The driver information center (DIC) will display the pressure for each of the front and rear tires.
When a tire with low air pressure is present, the DIC displays XX TIRE PRESSURE LOW.
ENGLISH DISPLAY UNITS (METRIC DISPLAY UNITS)
This display allows you to select between English and metric units of measurement if your vehicle has the uplevel DIC. Press the reset button to switch between English and metric units.
ENGINE BOOST (STS-V Only)
This display shows a graphic that indicates the amount of boost the engine is receiving in either pounds per square inch (psi) or kilopascals (kPa).
ENGINE OIL TEMPERATURE (STS-V Only)
This display shows the engine oil temperature in either degrees Fahrenheit (°F) or degrees Celsius (°C).
OIL PRESSURE (STS-V Only)
This display shows the oil pressure in either pounds per square inch (psi) or kilopascals (kPa).
TRANS (Transmission) FLUID TEMP (Temperature) (STS-V Only)
This display shows the transmission fluid temperature in either degrees Fahrenheit (°F) or degrees Celsius (°C).
Trip Information Display Menu
The following display menu items can be displayed by pressing the trip Information button:
Odometer: Press the trip information button until the odometer appears on the DIC display. The odometer shows the total distance the vehicle has been driven in either miles (mi) or kilometers (km) and cannot be reset.
Trip Odometer: Press the trip information button until trip odometer A or B appears on the DIC display. The trip odometer shows the current distance traveled since the last reset for each trip odometer in either miles (mi)
or kilometers (km). Both odometers can be used at the same time.
For base level vehicles, each trip odometer can be reset to zero separately by pressing and holding the bottom of the trip information button while the desired trip odometer
is displayed. For uplevel vehicles, reset each trip odometer by pressing the reset button or by pressing and holding the trip information button while the desired trip odometer is displayed.
Speed Alert
The Speed Alert feature notifies the driver what the legal speed limit is for the road the vehicle is currently travelling on. This feature also alerts the driver when the speed limit has been exceeded. Scroll through the DIC menus to display 'Speed Limit:
XXX MPH (Km/h). The displayed speed is the legal speed limit for the road. When the vehicle speed exceeds the legal speed limit, the warning 'Speed Limit: XXX MPH (Km/h) appears on the DIC.
The speed alert feature offers 4 selectable options:
- Speed Alert: OFF
- Speed Alert: At Limit (no offset)
- Speed Alert: +5 MPH (Km/h)
- Speed Alert: +10 MPH (Km/h)
Options 3 and 4 are offsets for the warning message. This means the warning message does not display until the vehicle speed exceeds the legal speed limit by 5 or 10 MPH (Km/h). When option 1 is selected (Speed Alert: OFF) no DIC warning message is displayed.
However, the speed limit will still be displayed by scrolling through the DIC menus. If the HUD is on there is no notification displayed in the DIC. If the HUD is not available or OFF, the notification is displayed in the DIC.
The IPC receives Speed Alert information as serial data messages from the radio/navigation system and does not have any control over the data being displayed. If the radio/navigation system does not send the speed alert message, the IPC displays "--"
"--" (dashes). This could be because there are no speed data for the road the vehicle is travelling on, a malfunction in the radio/navigation system or a GPS malfunction.
Speed Advisory
The Speed Advisory feature is similar to Speed Alert but only notifies the driver of what the 'advised' speed is. This would apply to roads such as highway exit ramps where there are recommended speed for the ramp. Scroll through the DIC menu to display
'Advisory: XXX MPH (Km/h). The notification to the driver is based on the offset for the Speed Alert listed above. Speed Advisory messages have a higher priority than Speed Alert messages. Speed Advisory notification can be turned off through the DIC. If the
HUD is on there is no notification displayed in the DIC. If the HUD is not available or OFF, the notification is displayed in the DIC.
The IPC receives Speed Advisory information as serial data messages from the radio/navigation system and does not have any control over the data being displayed. If the radio/navigation system does not send the Speed Advisory message, the IPC displays
"--" "--" (dashes). This could be because there are no speed data for the road the vehicle is travelling on, a malfunction in the radio/navigation system or a GPS malfunction.
