Cadillac 2007 STS Automobile User Manual


 
The mirror can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the
display reads a direction.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button
untilaCisshown in the compass display.
Compass Variance
The zone is set to zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if you live
outside zone eight. Under certain circumstances,
as during a long distance cross-country trip, it
will be necessary to adjust for compass variance.
Compass variance is the difference between
earth’s magnetic north and true geographic north.
If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance do the following:
1. Find the current location and variance
zone number on the following zone map.
2. Press and hold the on/off button until a zone
number appears in the display.
3. Once the zone number appears in the display,
press the on/off button quickly until the correct
zone number appears in the display. Stop
pressing the button and the mirror will return
to normal operation. If C appears in the
compass window, the compass may need
calibration. See Compass Calibration
listed previously.
