### Change Engine Oil

The driver information center (DIC) display the CHANGE ENGINE OIL message when the engine control module (ECM) determines that the engine oil life drops below 5 percent. The ECM sends a GMLAN message to the instrument panel cluster (IPC) requesting the CHANGE ENGINE OIL display. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System Resetting .

### Ice Possible

The driver information center (DIC) display ICE POSSIBLE for 10 seconds when the outside air temperature drops below 2.0°C (36°F). The instrument panel cluster (IPC) receives a GMLAN message indicating the outside air temperature from the HVAC/ECC (electronic Climate Control).

### Km/h and MPH

km/h: The instrument panel cluster (IPC) displays the km/h indicator when the cluster that Metric units have been requested.

MPH: The (IPC) displays the MPH indicator when the cluster detects that English units have been requested.

### Low Fuel

The driver information center (DIC) displays FUEL LEVEL LOW when the instrument panel cluster (IPC) determines that the fuel level is less than 7.84 percent. The IPC receives a GMLAN message indicating the fuel level from the engine control module (ECM).

### Low Oil Level

The driver information center (DIC) displays CHECK OIL LEVEL when the engine control module (ECM) detects a low oil level sensor/switch. The instrument panel cluster (IPC) receives a GMLAN indicating a low engine oil level condition.

### Low Oil Pressure

The driver information center (DIC) displays OIL PRESSURE LOW STOP ENGINE when the engine control module (ECM) detects low engine oil pressure condition from the engine oil pressure (EOP) sensor/switch. The instrument panel cluster (IPC) receives a GMLAN message requesting display of the indicator from the ECM.

### Service Vehicle Soon

The driver information center (DIC) displays SERVICE VEHICLE SOON when the engine control module (ECM) detects certain malfunctions that re not related to the emissions system. The instrument panel cluster (IPC) receives a GMLAN message requesting illumination from the instrument panel module (IPM).
