Tachometer - Pontiac 2003 Aztek Owner's Manual

Retro-Active Reset
The trip odometer has a feature called retro-active
reset. This feature can be used to set the trip odometer
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, push and
hold the tripheset 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.
