The DIC has different display modes which can be accessed by pressing the four buttons on the DIC. These buttons are labeled ON/OFF, SELECT right arrow, SELECT down arrow and RESET. The functions of these buttons is explained in the following sections.
Turn the system on or off by pressing the ON/OFF button once. When you turn on the ignition, the DIC will be in the mode last displayed when the engine was turned off.
To turn off messages on the DIC (except LOW OIL PRESSURE, LOW BRAKE FLUID, PARK BRAKE SET, STARTING DISABLED and the HOT...STOP ENGINE warning), press the RESET button.
Pressing the SELECT right arrow button will allow you to access the following modes, DATE/ET, FUEL, ECON, OIL and GAGE. While in any of these modes, warning messages can interrupt and take over the display until you acknowledge the message, or the condition causing the problem goes away.
English/Metric
The DIC can display information in either English or metric. To change the display, press and hold the ON/OFF button for about three seconds. This will also change the digital screen for the climate control system between English and metric.
Date/Elapsed Time
Pressing the SELECT down arrow while in DATE/ET mode will allow you to choose between the date and the elapsed time menus.
Date
To set the date, press and hold the RESET button for about three seconds while the date is being displayed on the DIC. When the date set mode is entered the display will show the following:
YEAR?_____MM/DD/00
The year will be flashing. To increase the item that is flashing press SELECT right arrow. To decrease the item that is flashing press SELECT down arrow.
When you reach the current year press the RESET button. The DIC will ask for the month. The month will flash the same as the year. Use the SELECT buttons to reach the current month and press RESET. The DIC will then ask for the day. The day will flash the same as the year. Use the SELECT buttons to reach the current day. Press the RESET button again and the set display will stop flashing and go back to the normal operation mode.
Elapsed Time (ET)
When the ignition is on, the DIC can be used as a stopwatch. The display will show hours and minutes. The elapsed time indicator will record up to 100 hours, then it will reset to zero and continue counting. Press SELECT down arrow while in the DATE/ET mode, and the display will show the amount of time that has elapsed since the elapsed time indicator was last reset (not including time the ignition is off), such as:
01:08 ELAPSED TIME
To start or stop the counting of time, press the RESET button briefly. If the colon (:) in the time is flashing, time is being counted. Time is displayed in hours and minutes. Seconds are not displayed. Time will continue to be counted as long as the ignition is on, even if another display is being shown on the DIC.
To reset elapsed time to zero, press the RESET button for three seconds while the elapsed time is displayed.
Fuel
Press the SELECT down arrow while in the FUEL mode to see how much fuel has been used and the fuel range functions.
Fuel Used
While in the FUEL USED function the display will show a reading such as:
FUEL USED: 10.4 GAL or FUEL USED: 39.4 L
To learn how much fuel will be used from a specific starting point, first enter the FUEL USED mode to display FUEL USED, then press and hold the RESET button for three seconds.
Don't confuse fuel used with the amount of fuel in your tank.
Fuel Range
The FUEL RANGE mode calculates the remaining distance you can drive without refueling. It's based on fuel economy and the fuel remaining in the tank. The display will show a reading such as:
FUEL RANGE: 235 MI or FUEL RANGE: 378 KM
If the range is less than 50 miles (80 km), the display will read LOW FUEL RANGE.
The fuel economy data used to determine fuel range is an average of recent driving conditions. As your driving conditions change, this data is gradually updated. Fuel range cannot be reset.
Fuel Economy
Pressing the SELECT down arrow while in the ECON mode displays average fuel economy and instantaneous fuel economy calculated for your specific driving conditions.
Average fuel economy will be shown in a reading such as:
25.2 AVG MI/GAL or 9.3 AVG L/100 KM
Instantaneous fuel economy will be shown in a reading such as:
28 INST MI/GAL or 8.4 INST L/100 KM
The average fuel economy is viewed as a long-term approximation of your overall driving conditions.
If you press and hold RESET for three seconds in this mode while you're driving, the system will begin figuring average fuel economy from that point in time. Instantaneous fuel economy cannot be reset.
Oil Life
The GM Oil Life System™ is the only function accessible in the OIL mode. Engine oil life is displayed in a reading such as the following:
OIL LIFE 30%
This is an estimate of the oil's remaining useful life. It will show 100% when the system is reset after an oil change. It will alert you to change your oil on a schedule consistent with your driving conditions.
When the remaining oil life is low, the system will alert you with this message:
CHANGE OIL SOON
Always reset the OIL LIFE reminder after an oil change. To reset the oil life system, see "How to Reset the Oil Life System" under Engine Oil .
Remember, you must reset the OIL LIFE yourself after each oil change. It will not reset itself. Also, be careful not to reset the OIL LIFE accidentally at any time other than when the oil has just been changed. It can't be reset accurately until the next oil change.
The DIC does not replace the need to maintain your vehicle as recommended in the Maintenance Schedule in this manual. Also, the oil change reminder will not detect dusty conditions or engine malfunctions that may affect the oil. If you drive in dusty areas, change your oil after every 3,000 miles (5 000 km) or three months, whichever occurs first, unless the DIC instructs you to do so sooner. Also, the oil change reminder does not measure how much oil you have in your engine. So, be sure to check your oil level often. See Engine Oil .
Gage
Pressing the SELECT down arrow while in GAGE mode will allow you to access the battery volts, oil pressure and tire pressure displays. Pressing and holding the RESET button for three seconds while in average speed and tire pressure displays will reset them. Pressing the SELECT down arrow in GAGE mode will show the following displays:
| • | Battery voltage, such as the following: |
| VOLTS:13.8 |
| • | Oil pressure, such as the following: |
| OIL PRESSURE 40 PSI or OIL PRESSURE 276 KPA |
| • | Average speed, such as the following: |
| AVG SPEED 55 MPH or AVG SPEED 90 KM/H |
| • | Tire pressure status, such as the following: |
| TIRE PRESSURE NORMAL or TIRE PRESSURE LOW |
| TIRE PRESSURE NORMAL appears when the check tire pressure system believes your vehicle's tire pressures are normal. If a potential tire pressure problem is detected, the display will show TIRE PRESSURE LOW. If you see this message, you should stop as soon as you can and check all four tires for damage. If a tire is flat, see If a Tire Goes Flat . Also check the tire pressure in all four tires as soon as you can. See Inflation - Tire Pressure . |
| There are times when you will have to reset (calibrate) the check tire pressure system. Pressing the RESET button while the TIRE PRESSURE LOW warning is displayed does not automatically reset the tire pressure monitoring system. See Check Tire Pressure System for more information. |
