Driver Controls AUTOMATIC DIMMING INSIDE REAR VIEW MIRROR (IF EQUIPPED) Your vehicle is equipped with an inside rear view mirror which has an auto-dimming function. The electrochromic day/night mirror will change from the normal (high reflective) state to the non-glare (darkened) state when bright lights (glare) reach the mirror. When the mirror detects bright light from front or behind, it will automatically adjust (darken) to minimize glare. The mirror will automatically return to the normal state whenever the vehicle is placed in R (Reverse)(when the mirror is on) to ensure a bright clear view when backing up. Do not block the sensor on the backside of the mirror since this may impair proper mirror performance. Electronic compass (if equipped) The compass reading will remain accurate during most driving conditions. The compass is continuously re-calibrating due to changing magnetic fields and subtle, slow changes in vehicle magnetics which can occur over the life of the vehicle. If heading appears inaccurate re-calibrate mirror, refer to Compass calibration adjustment. The compass reading will remain fixed when significant levels of magnetic interference are experienced (such as steel bridges). The compass will return to normal operation upon leaving the magnetized area. If highly magnetized items (such as magnetic mount antennas) are placed very near the compass the display will change to "C". If a "C" is displayed, remove the source of magnetic interference and re-calibrate compass, refer to Compass calibration adjustment. Most geographic areas (zones) have a magnetic north compass point that varies slightly from the northerly direction on maps. A correct zone setting will eliminate this error. You MUST set the mirror to the proper zone to get an accurate compass reading, refer to Compass zone adjustment. 53 2007 05+ Mustang (197) Owners Guide (post-2002-fmt) USA (fus)
