Pontiac 2005 Grand Prix - Manual (Page 166)

The trip odometer has a feature called the retro-active
reset. This 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 the trip
odometer is not reset at the beginning of the trip.
To use the retro-active reset feature, press and hold the
set/reset button for at least three seconds. The trip
odometer will display the number of miles or kilometers
driven since the ignition was last turned on and the
vehicle was moving. Once the vehicle begins moving,
the trip odometer will accumulate mileage. For example,
if the vehicle was driven 5.0 miles (8.0 km) before it
is started again, and then the retro-active reset feature
is activated, the display will show 5.0 miles (8.0 km).
As the vehicle begins moving, the display will then
increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the
display will show the number of miles or kilometers that
were driven during the last ignition cycle.
Average Speed: The average speed is displayed in
miles per hour (mph) or kilometers per hour (km/h). The
average speed is calculated from the various vehicle
speeds recorded since the last reset of this menu item.
To reset the average speed, press the set/reset
button. The display will return to zero.
Press the trip odometer button again to advance to the
next screen.
Time Elapsed: This screen can be used as a
stopwatch. The display can show the hours, minutes
and seconds. The elapsed time indicator will record up
to 99 hours, 59 minutes and 59 seconds, then it will
reset to zero and continue counting.
To set the time elapsed function, use the following
procedures:
1. Press the set/reset button for less than two seconds
to start or stop the timer.
2. Press and hold the set/reset button for more than
two seconds to reset the timer back to zero.
