1995 Oldsmobile Aurora Owner's Manual - Page 114

EMiUM UNLEAOED FUEL ON @ Tachometer C 2 Your trip odometer tells you how far you have driven since you last reset it. Press the trip button located next to the trip odometer, below the fuel gage. Your Aurora has a tamper resistant odometer. If you see silver lines between the numbers, you'll know someone has probably tampered with it and the numbers may not be true. You may wonder what happens if your vehicle needs a new odometer installed. If the new one can be set to the mileage total of the old odometer, then it must be. But if it can't, then it's set at zero and a label must be put on the driver's door to show the old mileage reading when the new odometer was installed. The tachometer displays the engine speed in revolutions per minute (RPM). If your engine speed equals or exceeds the safe limit for operation, the message HOT...REDUCE ENGINE RPM is displayed on the information center. 2-62
