Control Buttons The trip computer has three buttons that control its functions. ENG/MET (English/Metric): Press this button to change the display from English to metric units or metric to English. RESET: Press this button for two seconds to reset the mode displayed. MODE: Press this button to change the mode being displayed. RANGE: Shows how much farther you can travel with the fuel you have remaining in the gas tank before refueling. When the range displays L, for 40 to 50 miles (64.36 to 80.45 km), the display will flash LOW continuously. The range is calculated from the AVG ECON value multiplied by the fuel remaining in the tank. LOW: This light will come on the vehicle outline when the ignition is on and the fluid in the washer fluid container is low. DOOR AJAR: If one of the doors is left ajar, a light will appear next to that door on the vehicle outline. BOOST GAGE: If you have the 3800 V6 supercharged engine, this gage will show the amount of boost the engine is receiving. TRUNK AJAR: If the trunk is not fully closed, the trunk area will light up on the vehicle outline. LOW TRAC (Low Traction): This light will come on when the enhanced traction system (3100 or 3800 V6 engine) or the traction control system (3800 supercharged V6 engine) is limiting wheel spin. See "Traction Control System" "Enhanced Traction System" and "Low Traction Light" in the Index. Functions FUEL USED: Shows the total amount of fuel used since you last reset this mode. The amount can be displayed in gallons or liters. AVG ECON (Average Economy): Shows the average fuel economy since you last reset this mode. OIL LIFE: Shows a percentage of the oil's remaining useful life. The system predicts remaining oil life using data from length of drives, coolant temperature, engine rpm and vehicle speed. Each time you get an oil change, be sure to reset this function so that it will give you an accurate percentage. See "How to Reset the GM Oil Life System " in the Index. t 2-95
