Driver Controls ELECTRONIC COMPASS (IF EQUIPPED) The compass heading is displayed in the center integrated display (CID). The compass reading may be affected when you drive near large buildings, bridges, power lines and powerful broadcast antenna. Magnetic or metallic objects placed in, on or near the vehicle may also affect compass accuracy.

If the compass still appears to be inaccurate, a manual calibration may be necessary. Refer to Compass calibration adjustment.
