Speedometer/Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour
(M). Your
odometer shows how far your vehicle has been driven in
either miles (used in the United States) or in kilometers
(used in Canada).
Your Oldsmobile 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 accurate.
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 that will be done.
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.
Trip Odometer
Your trip odometer tells how far you have driven since
you last reset it. To set it to zero, press the RESET
button on the right side of the instrument cluster.
