• | Delayed Door Lock

• | Display Language

• | Easy Exit Seat

• | Exit Lighting

• | Memory Seat Recall

• | Remote Door Lock

• | Remote Door Unlock

• | Park Tilt Mirrors

#### Average Fuel Economy

Average fuel economy is calculated using the equation: AFE = Distance/Fuel

• | Distance = The accumulated distance travelled since the last reset of this value

• | Fuel = The accumulated fuel consumption since the last reset of this value

The engine control module (ECM) sends the average fuel economy serial data message to the instrument panel cluster (IPC). The value of this mode is retained during ignition OFF and can be changed between English units and metric units by selecting from the driver information center (DIC) options menu.

#### Average Speed

Average speed is calculated using the equation: Average Speed = AVS Distance/AVS Time

• | Distance = The accumulated distance travelled since the last reset of this value

• | Ignition On = The accumulated ignition on time since the last reset of this value

#### Oil Life Remaining

The ECM sends the oil life remaining percentage to the IPC via a serial data message. The instrument panel cluster receives a serial data message indicating the engine oil life remaining. The DIC displays the current percentage of the GM Oil Life System as determined by the ECM. When the oil life remaining percentage drops below 5 percent, the DIC displays CHANGE ENGINE OIL SOON. When the engine oil is changed, reset the GM Oil Life System. Refer to GM Oil Life System Resetting.

#### Fuel Range

This message indicates the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions since the last battery connection to the IPC. Fuel Range is calculated using the equation: Fuel Range = Range Distance/Range Fuel Used.

• | Range Distance = The accumulated distance travelled since the last reset of this value.

• | Fuel Used = The accumulated fuel delivered since the last reset of this value

The ECM sends the fuel range value to the IPC. The IPC receives a serial data message with fuel information. The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the DIC English/Metric menu. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.

#### Fuel Used

The DIC calculates and displays the total amount of fuel used since the last reset operation. You can reset the fuel used mode by depressing and holding the Set/Reset button for more than 3 seconds. The value of this mode is retained during ignition OFF.

#### Tire Pressure Monitor

The IPC receives a GMLAN message from the tire pressure monitoring (TPM) system for front and rear tire pressure data. The DIC will display the pressure for each of the front and rear tires. When a tire with low air pressure is present, the DIC displays a warning, CHECK XX TIRE PRESSURE.

#### Trip Time

The timer records elapsed time starting from activation. When the DIC displays the timer, pressing the Set/Reset switch for longer than 1 second on the DIC resets the timer. Pressing the Set/Reset button on the DIC switch for approximately 1 second 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).

#### Park Assist Menu

The park assist menu is displayed in the DIC. The DIC displays the current state of the park assist until the IPC receives a message indicating otherwise. The DIC displays (-- -- --) when communication with park assist is lost.

#### Fuel Display

Parameter | Update Rate | Range | Reset Value | Units
--- | --- | --- | --- | ---
Average Fuel Economy | 1 second | 0.0-99.9 | 99.9 | MPG or L/100 KM
Fuel Range | 1 second | 0-999 | N/A | MI/KM
Fuel Used | 1 second | 0-999.9 | 0.0 | Gal/L

### English/Metric

The English/Metric mode is used to toggle between English and Metric units and can be accessed through the driver information center (DIC) Vehicle Info switch.

### Trip A/B

The trip odometer A or B can be accessed through the DIC Trip/Fuel switch function.

#### Trip Display

DIC Trip Display | Range
--- | ---
Metric | English
ODOMETER | ######km | ######MI
TRIP A | ####.#km | ####.#MI
TRIP B | ####.#km | ####.#MI

### Language

The driver information center (DIC) is capable of displaying in 3 languages

• | English

• | French

• | Spanish

### Compass

The driver information center (DIC) displays the compass based on serial data message from the BCM. The compass module communicates with the body control module (BCM) through a bi-directional data circuit. The instrument panel cluster (IPC) receives compass information from the BCM via the serial data circuit. The compass is displayed in the DIC with other vehicle information and is displayed at the bottom line of the DIC. The compass displays "- -" (dashes) when a malfunction is present with the compass module or a compass serial data communication fault exists. The compass displays 'CAL' or 'C' when the compass needs to be calibrated. Cycle the ignition before performing the compass magnetic variation zone adjustment procedure. The DIC vehicle information switch allows the compass zone to be changed or the compass recalibrated.

Check that the compass module is properly installed in the vehicle since this may cause the compass to malfunction. The embossed arrow on the top of the compass module should be parallel to the centerline of the vehicle.
