TSB: 2018 model year ES 300h and ES 350 vehicles are equipped with a compass in the rear view mirror. Use the following procedure to complete initial calibration of the compass during Pre-Delivery Service (PDS). NOTE: When the compass is NOT in calibration mode, pushing the mirror switch will toggle the compass display ON and OFF. NOTE: ? Do NOT perform calibration of the compass in a place where the Earth's magnetic field is subject to interference by artificial magnetic fields (underground parking, under a steel tower, between buildings, roof parking, near a railroad crossing, near a large vehicle, etc.). ? During calibration, do NOT operate electric systems (moon roof, power windows, etc.) as they may interfere with the calibration.
