Buick 2006 LaCrosse - Manual (Page 174)

There is also a retroactive trip odometer function that
performs the following for each trip odometer:
• If the vehicle’s speed has exceeded 3 mph (5 km/h)
during the current ignition cycle, this function will
set the trip odometer to the distance driven
during the current ignition cycle.
• If the vehicle’s speed has not exceeded 3 mph
(5 km/h), this function will set the trip odometer
to the distance driven during the previous ignition
cycle plus the distance driven during the current
ignition cycle.
Press and hold the set/reset button on the uplevel
vehicle or the trip/odometer button on the base level
vehicle for three seconds, then release the button.
The retroactive trip odometer value will be set into the
currently displayed trip odometer.
Time Elapsed (Uplevel Only)
Press the trip/odometer button until TIME ELAPSED :00
displays. This mode is like a stopwatch, in that you
can clock the time it takes to get from one point
to another. Each of the fields for the hours, minutes,
and seconds are two numeric digits.
Once TIME ELAPSED :00 is displayed, press the
set/reset button on the uplevel vehicle to start the timing
feature. Press the set/reset button again to stop it.
If you will be starting and stopping your vehicle, during
a trip for instance, the TIME ELAPSED feature will
automatically start timing where it left off when you
last stopped. To reset it, press and hold the set/reset
button for approximately 1.5 seconds. The display
will return to zero. Press the trip/odometer button to
exit from the TIME ELAPSED display.
Average Speed (Uplevel Only)
Press the trip/odometer button until AVERAGE SPEED
displays. This mode shows the average speed of
the vehicle in miles per hour (mph) or kilometers per
hour (km/h). This average is calculated based on
the various vehicle speed recorded since the last reset
of this value. To reset the value, press the trip/odometer
button to display AVERAGE SPEED, then press and
hold the set/reset button on the uplevel vehicle.
The display will return to zero.
