Warnings And Messages
The message center warning messages alert the operator to possible concerns or malfunctions in the vehicle operating systems. Warning messages are generally associated with other observable outputs of the IPC (gauges, informational indicators and RTT indicators). For example, when the ABS module detects a low brake fluid condition, the ABS module sends the IPC a request through the GWM to illuminate the brake warning indicator and a request to display the LOW BRAKE FLUID message in the message center. This allows the message center to be a more informative supplement to the IPC gauges and indicators.
Adaptive Cruise Control
The message center provides messages explaining the need for driver intervention and system status. The adaptive cruise control messages are supplemental to the cruise control RTT indicator and the adaptive cruise control warning chime.
Adaptive Headlamps
The message center provides the adaptive headlamp fault message to inform the driver of a fault with the adaptive headlamps.

Engine Oil Life, Engine Oil Change Minder
The instrument cluster provides messages to inform the driver about the engine oil life status, engine oil life reset status and when an engine oil change is required. The duration of the interval between engine oil changes is calculated in the PCM and varies due to driving conditions. The PCM assumes a base mileage of 16, 090 km (10, 000 mi) or 1 year for normal driving. However, this number is adjusted down for conditions such as high engine temperature, high engine rpm, use of flex fuel and possibly low engine oil level. The PCM calculates and provides the engine oil life percent message to the IPC. The engine oil change minder can be reset at any time by the driver.
Factory Keycode
The message center can display the original factory keycode when requested.
Factory/Transport Mode
During vehicle build, some modules, such as the IPC and the BCM, are set in factory mode. While in the factory mode the IPC displays FACTORY MODE CONTACT DEALER in the message center. If the vehicle is set in factory mode, the system does not automatically exit the mode and must be manually set to either the transport or normal operation mode.
When the vehicle build is complete, the vehicle is set to transport mode. While in transport mode, the IPC displays TRANSPORT MODE CONTACT DEALER in the message center. Transport mode is used to reduce the drain on the battery during longer periods where the vehicle is not used. Various systems may be altered or are disabled when in the transport mode. The vehicle automatically reverts to normal operation mode after being driven 201 km (125 mi).
To deactivate factory mode, Refer to: Factory Mode Deactivation . . To deactivate transport mode, Refer to: Transport Mode Deactivation .

Low Engine Oil Level
The message center provides a low engine oil level warning message to inform the driver the engine oil level is low. The engine oil level (EOL) sensor is a normally open sensor, hardwired to the PCM. The PCM monitors the change in voltage on the sensor signal circuit. When the oil level is high, the float rises and the sensor circuit closes, pulling the voltage low. When the oil level is low, the sensor circuit opens, pulling the voltage high, signaling the PCM the engine oil level is low. If the sensor is disconnected or stuck open, the low engine oil message will display. The PCM sends the engine oil level warning request message to the IPC to display the low engine oil level message in the message center.

Once the driver places the ignition in the RUN state, the IPC carries out its startup sequence.
Reverse Brake Assist
The message center provides a warning message through the rear parking aid or CTA system that an object has been detected to the rear of the vehicle, when travelling at a low speed in reverse gear. The system applies the brakes for a short period of time until the driver takes action to control the vehicle.
Seatbelt
The message center provides a message to indicate the status of the front row seatbelts and if they are buckled.
Side Wind Compensation
