Engine Coolant Temperature Gauge

The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a GMLAN message from the ECM indicating the engine coolant temperature. The engine coolant temperature gauge defaults to 60°C or below if:

    • The ECM detects a malfunction in the engine coolant temperature sensor circuit.
    • The IPC detects a loss of GMLAN communications with the ECM.
    • The BCM detects a loss of GMLAN communications with the ECM.

Fuel Gauge

The instrument panel cluster (IPC) displays the fuel level as determined by the ECM. The IPC receives a GMLAN message from the ECM indicating the fuel level percent. The fuel gauge defaults to empty if:

    • The ECM detects a malfunction in the fuel level sensor circuit.
    • The IPC detects a loss of GMLAN communications with the ECM

When the fuel level is less than a pre-determined value, the low fuel or very low fuel indicators illuminate on the centre Multifunction Display (MFD).

Odometer

The IPC contains an odometer and trip odometer A or B. Momentarily press the TRIP button on the steering wheel in order to toggle between the odometer and the trip odometer. Press the ENTER button for approx. 10 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC calculates the distance travelled based on the GMLAN vehicle speed information from the ECM. The odometer will display 'error' if an internal IPC memory failure is detected.

PRNDL Display

The IPC displays the selected gear position as determined by the ECM. The IPC receives a GMLAN message from the ECM indicating the gear position. The PRNDL display blanks if:

    • The ECM detects a malfunction in the transmission range switch circuit.
    • The IPC detects a loss of GMLAN communications with the ECM.

Speedometer

The IPC displays the vehicle speed as determined by the ECM. The IPC calculates the kilometres based on the GMLAN vehicle speed information from the ECM. The speedometer defaults to 0 km/h if the IPC detects a loss of GMLAN communications with both the ECM.

Tachometer

The IPC displays the engine speed as determined by the ECM. The IPC receives a GMLAN message from the ECM indicating the engine speed. The tachometer will default to 0 RPM if:

    • The ECM detects a malfunction in the engine speed sensor circuit.
    • The IPC detects a loss of GMLAN communications with the ECM.

LOW FUEL

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

When the Low Engine Oil Level indicator displays in the IPC or DIC due to a low engine oil level condition, make sure that the ignition is turned OFF before adding or changing the oil in the vehicle. Failure to do so may result in the Low Engine Oil Level indicator or message staying on after the engine attains the correct oil level.

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.

Warning Messages

Ignition On

Pressing the TRIP button any time during the system check causes the display to jump ahead to the last trip computer screen displayed before the ignition key was last switched off. The system check continues to run in the background.

Ignition Off

When you switch off the ignition, the odometer screen appears on the screen unless a service reminder is active. Active service reminders are displayed for 10 seconds before the odometer appears.

Warning lamps and Reminders

The following warning lamps and reminders indications may appear on your instrument panel cluster centre display (depending on the level of your vehicle).

They appear as illuminated icons, animated symbols or a combination of both.

Shift Up

On vehicles without a red line on the tachometer scale, the Engine at Redline or Change Up Gear animation illuminates and a chime sounds to indicate that the engine revolutions per minute (RPM) are too high. Engine at Redline appears when the vehicle is stationary. If the warning appears, reduce the engine RPM.

Change Up Gear appears when the vehicle is moving. If this warning appears, change up a gear.

Malfunction indicator lamp - MIL

This vehicle is fitted with an emission monitoring system. The Malfunction indicator lamp illuminates when the ignition is switched on and extinguishes shortly after the engine has started.

If the lamp and the Check Engine animation illuminate while you are driving, the emission system may require servicing. Although the vehicle may still be drivable and not require recovery. If the lamp flashes when you are driving, reduce your speed until the lamp stops flashing.

Service Vehicle Soon

If the Service Vehicle Soon animation illuminates when you are driving, it indicates a non-emissions related fault in the electronic engine management system or the automatic transmission. Although the vehicle may still be drivable, it is recommended that you reduce your driving speed and do not tow heavy loads or a heavily loaded vehicle. Have the problem fixed as soon as possible.

The Service Vehicle Soon animation is displayed until you press the TRIP button. The animated symbol then reverts to the original trip computer display. A small icon will appear in the display and remains illuminated until the problem has been rectified.

Service Due

The Service Due animation first appears 1000 km before a service is due, giving you time to arrange for the service to be carried out. The message is shown for 10 seconds whenever the ignition is turned ON or OFF.

Safety Mode

If the Safety Mode and Power reduced animation's illuminate alternately while you are driving, it indicates a fault in the electronic throttle control system. Although the vehicle may still be drivable, the throttle available may be limited, resulting in reduced power. The Safety Mode and Power reduced animation's are displayed until you press the TRIP button. They then revert to the original trip computer display.

Safety appears at the bottom of the display and remains illuminated until the problem has been rectified.

Cruise Control

The Cruise On animation illuminates when the cruise control is activated and ready for use.

Seat belt warning lamp

The Seat belt warning lamp is designed to remind vehicle occupants to fasten their seat belts. The Seat belt warning lamp illuminates for a short time when the ignition is turned on to check that the lamp is working.

Additional seat belt warning

If the driver's and/or front passenger's seat belt are not fastened within a certain period of time, the warning lamp flashes. The Fasten seat belt animation is displayed and a chime sounds if the driver's and/or front passenger's seat belt are still not fastened when the vehicle speed reaches or exceeds 25 km/h. The warning message reverts to the original trip computer display when the vehicle's speed drops below 25 km/h. The warning lamp stops flashing once both seat belts are fastened securely. If one or both seat belts are unfastened while the ignition is on, the warning and chime sequence will start again.

Low washer fluid

If the Low washer fluid animation illuminates while you are driving, it indicates that the washer fluid level is low. Top up the washer fluid reservoir.
