Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). 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 Buick has a tamper-resistant odometer. If you see
ERROR, 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 will be 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 button on the
right side of the instrument cluster.
Your triphelect reset switch will go back and forth
between the odometer and the trip odometer if the button
is pressed and released within 1.5 seconds. If the button is
pressed and held for longer than 1.5 seconds while in the
trip odometer mode, it will be reset to zero. If the button
is pressed and held for longer than 1.5 seconds while in
the odometer mode, it will have no effect.
