Buick 2005 Park Avenue - Manual (Page 100)

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 COMPASS (or the on/off button for
mirrors equipped with OnStar ® controls) until a
zone number appears in the display.
3. Once a zone number appears in the display, press
the COMPASS button (or the on/off button for
mirrors equipped with OnStar
® controls) quickly until
the correct zone number appears in the display. If
C appears in the compass window, the compass
may need calibration. See “Compass Calibration”
explained previously.
Outside Manual Mirrors
If the vehicle has manual outside mirrors, adjust them
by hand so that the side of the vehicle can be seen while
you are sitting in a comfortable driving position.
The mirrors can be folded inward to prevent damage
when going through an automatic car wash. To
fold, push the mirror toward the vehicle. To return the
mirror to its original position, push outward. Return both
mirrors to the unfolded position before driving.
