RADIO WARNING MESSAGES

CHECK OIL LEVEL
This message indicates that a low oil level exists.

CHANGE ENGINE OIL
The driver information center (DIC) illuminates the CHANGE ENGINE OIL message when the engine control module (ECM) determines that the engine oil life is 0 percent. The ECM sends a class 2 message to the radio requesting illumination. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System - Resetting in Maintenance and Lubrication.

ICE POSSIBLE
The radio illuminates the ICE POSSIBLE message when the outside air temperature drops below 2.0°C (36°F). When the temperature rises above 5.5°C (42°F), the ICE POSSIBLE message turns OFF. The radio receives a class 2 message indicating the outside air temperature from the dash integration module (DIM).

KM/H AND MPH

KM/H
The instrument panel cluster (IPC) illuminates the km/h indicator when the radio detects that metric units have been requested via the Eng/Met button. The radio sends a class 2 message indicating the requested units to the IPC.

MPH
The IPC illuminates the MPH indicator when the radio detects that English units have been requested via the Eng/Met button. The radio sends a class 2 message indicating the requested units to the IPC.

LOW FUEL
The radio illuminates the FUEL LEVEL LOW message in the radio when the instrument panel cluster (IPC) determines that the fuel level is less than 9.48 liters (2.5 gallons). The IPC receives a class 2 message indicating the fuel level from the engine control module (ECM).

LOW OIL LEVEL
The radio illuminates the CHECK OIL LEVEL message when the engine control module (ECM) detects low engine oil level, and the signal circuit is low. The ECM only monitors the signal circuit of the engine oil level switch for a brief period when the key moves from ON to START. The radio receives a class 2 message requesting illumination from the ECM.

LOW OIL PRESSURE
The radio illuminates the OIL PRESSURE LOW STOP ENGINE message when the engine control module (ECM) detects low engine oil pressure, and the signal circuit is low. The radio receives a class 2 message requesting illumination from the ECM.

SERVICE VEHICLE SOON
The radio illuminates the SERVICE VEHICLE SOON message when the engine control module (ECM) detects certain malfunctions that are not related to the emissions system. The radio receives a class 2 message requesting illumination from the ECM.

TOP SPEED FUEL CUT OFF (Export Only)
The radio illuminates the TOP SPEED FUEL CUT OFF message when the engine control module (ECM) detects that the vehicle speed is more than 120 km/h (75 mph). The radio receives a class 2 message requesting illumination from the ECM.

VEHICLE OVERSPEED (Export Only)
The radio illuminates the VEHICLE OVERSPEED message when the instrument panel cluster (IPC) detects that the vehicle speed is more than 120 km/h (75 mph). The radio receives a class 2 message requesting illumination from the IPC.
