Compass Calibration - Pontiac Torrent 2009 Owner's Manual

Compass Calibration

The compass can be manually calibrated. Only calibrate
the compass in a magnetically clean and safe location,
such as an open parking lot, where driving the vehicle in
circles is not a danger. It is suggested to calibrate
away from tall buildings, utility wires, manhole covers, or
other industrial structures, if possible.
If CAL should ever appear in the DIC display, the
compass should be calibrated.
If the DIC display does not show a heading, for example,
N for North, or the heading does not change after
making turns, there may be a strong magnetic field
interfering with the compass. Such interference may be
caused by a magnetic CB or cell phone antenna
mount, a magnetic emergency light, magnetic note pad
holder, or any other magnetic item. Turn off the
vehicle, move the magnetic item, then turn on the
vehicle and calibrate the compass.
To calibrate the compass, use the following procedure:
Compass Calibration Procedure
1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in
which the vehicle is located. See "Compass
Variance (Zone) Procedure" earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.
2. Press the vehicle information button until PRESS
TO CALIBRATE COMPAS (Compass) displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE
IN CIRCLES. Drive the vehicle in tight circles at
less than 5 mph (8 km/h) to complete the
calibration. The DIC will display CALIBRATION
COMPLETE for a few seconds when the calibration
is complete. The DIC display will then return to
the previous menu.
