GMC Sierra Owners Manual
Vehicle Information Menu Items (with DIC Buttons)
(Vehicle Information): Press this button to scroll through the following menu items:
Press the vehicle information button until OIL LIFE REMAINING displays. This display shows an estimate of the oil's remaining useful life. If you see 99% OIL LIFE REMAINING on the display, that means 99% of the current oil life remains. The engine oil life system will alert you to change the oil on a schedule consistent with your driving conditions.
When the remaining oil life is low, the CHANGE ENGINE OIL SOON message will appear on the display.
See “CHANGE ENGINE OIL SOON” under Engine Oil Messages on page 5‑45. You should change the oil as soon as you can. See Engine Oil on page 10‑7. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Maintenance Schedule on page 11‑3 for more information.
Remember, you must reset the OIL LIFE display after each oil change.
It will not reset itself. Also, be careful not to reset the OIL LIFE display accidentally at any time other than when the oil has just been changed. It cannot be reset accurately until the next oil change.
To reset the engine oil life system, see Engine Oil Life System on page 10‑10.
Press the vehicle information button until UNITS displays. This display allows you to select between metric or English units of measurement.
Once in this display, press the set/ reset button to select between METRIC or ENGLISH units. All of the vehicle information will then be displayed in the unit of measurement selected.
If the vehicle has the Tire Pressure Monitor System (TPMS), the pressure for each tire can be viewed in the DIC. The tire pressure will be shown in either kilopascals (kPa) or pounds per square inch (psi). Press the vehicle information button until the DIC displays FRONT TIRES kPa (PSI) LEFT ## RIGHT ##. Press the vehicle information button again until the DIC displays REAR TIRES kPa (PSI) LEFT ## RIGHT ##.
If a low tire pressure condition is detected by the system while driving, a message advising you to add pressure in a specific tire will appear in the display. See Tire Pressure on page 10‑62 and Tire Messages on page 5‑49 for more information.
If the tire pressure display shows dashes instead of a value, there may be a problem with the vehicle.
If this consistently occurs, see your dealer for service.
Trailer Gain and Output
On vehicles with the Integrated Trailer Brake Control (ITBC) system, the trailer brake display appears in the DIC. Press the vehicle information button until TRAILER GAIN and OUTPUT display.
TRAILER GAIN shows the trailer gain setting. This setting can be adjusted from 0.0 to 10.0 with either a trailer connected or disconnected.
OUTPUT shows the power output to the trailer any time a trailer with electric brakes is connected. Output is displayed in 0 to 10 bars. Dashes may appear in the OUTPUT display.
To adjust trailer gain see “Integrated Trailer Brake Control System” under Towing Equipment on page 9‑100 for more information.
This display shows the current battery voltage. If the voltage is in the normal range, the value will display. For example, the display may read BATTERY 13 VOLTS.
Your vehicle's charging system regulates voltage based on the state of the battery. The battery voltage may fluctuate when viewing this information on the DIC. This is normal.
This display shows the oil pressure in either kilopascals (kPa) or pounds per square inch (psi).
Press the vehicle information button until ENGINE HOURS displays. This display shows the total number of hours the engine has run.
