CTS RWD V6-3.6L (2008)
The IPC calculates IFE based on fuel information message from the ECM. 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 accessing the DIC
trip/fuel information switch. The IFE display cannot be reset.
Trip Time
The timer records elapsed time starting from activation. When the DIC displays the timer, pressing the SET/RESET switch for 1.5 second on the DIC
resets the timer. Pressing the SET/RESET button on the DIC switch starts and stops the timer. The DIC displays the timer in one of the following
formats:
The DIC displays the timer in the following format: XX: XX:XX:
The first XX represents hours elapsed, the second XX represents minutes elapsed, and the third XX represents seconds elapsed. 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).
Battery Voltage
Battery voltage data is not determined by the DIC and is not a resettable parameter. The DIC displays (- - -) when an invalid battery data is received or
when the IPC experiences a loss serial data communication.
Engine Oil Life Remaining
The Engine Oil Life Remaining displays the estimated percentage of oil life remaining. The engine control module (ECM) sends the oil life remaining
data to the instrument panel cluster (IPC) via serial data message. The driver information center (DIC) displays the current percentage of the GM Oil
Life System as determined by the ECM. When the engine oil life remaining percentage drops below a pre-determined value, the DIC displays CHANGE
ENGINE OIL SOON message. When the engine oil is changed, reset the GM Oil Life System. Refer to GM Oil Life System Resetting (See: Oil Change
Reminder Lamp/Service and Repair) .
Tire Pressure Monitor
The instrument panel cluster (IPC) receives serial data message from the tire pressure monitoring (TPM) system indicating the front and rear tire
pressure. The driver information center (DIC) will display the pressure for each of the front and rear tires. Tire pressure values are not resettable through
the DIC. The tire programming menu can only be achieved with the vehicle transmission in PARK.
Park Assist Menu
The park assist menu is displayed in the driver information center (DIC) to indicate the ON/OFF status. The DIC displays the current state of the park
assist until the instrument panel cluster (IPC) receives a serial data message from the BCM indicating a status change. The DIC displays (- - -) when
communication with park assist is lost.
Key FOB Programming Menu
The key fob programming menu is used to initiate programming of the key fobs. The key fob programming menu can only be achieved with the vehicle
transmission in PARK.
English/Metric Button
The English/Metric button is used to toggle between English and Metric unit and can be accessed through the DIC trip/fuel switch.
Trip Odometer A/B
The trip odometer A or B can be accessed through the DIC trip/fuel switch.
Odometer
The instrument panel cluster (IPC) displays the vehicle odometer in the driver information center (DIC). The IPC calculates the vehicle odometer based
on serial data vehicle speed information from the engine control module (ECM). The IPC stores the odometer information in non volatile memory and
