Tachometer - Pontiac 2005 Montana Owner's Manual

Retro-Active Reset
Each of the two trip odometers has a feature called
retro-active reset. This feature can be used to set
either or both trip odometer(s) to the number of
miles (kilometers) driven since the ignition was last
turned on. This can be used if you forget to reset your
trip odometer at the beginning of a trip. To use the
retro-active reset feature, press and hold the trip/reset
button for at least three seconds. The trip odometer
will then display the number of miles (kilometers) driven
since the ignition was last turned on and you began
driving. If you use the retro-active reset feature after you
have started the vehicle, but before you begin moving,
the display will show the number of miles (kilometers)
you drove during the last ignition cycle. Once you begin
driving, the trip odometer will accumulate mileage.
For example, if you have driven 5.0 miles (8.0 km) since
you started your vehicle, and then activate the
retro-active reset feature, the display will show 5.0 miles
(8.0 km). As you drive, the display will then increase
to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc. Only
the trip odometer that is displayed will be affected by
the retro-active reset so that both trip odometers can be
used separately.
