3-76 Instruments and controls ! Photosensors The mirror has a photosensor attached on both the front and back sides. During nighttime driving, these sensors detect distracting glare from vehicle headlights behind you and automatically dim the mirror to eliminate glare and preserve your vision. For this reason, use care not to cover the sensors with stickers, or other similar items. Periodically wipe the sensors clean using a piece of dry soft cotton cloth or an applicator. ! Compass zone adjustment Compass calibration zones 1. Refer to the “Compass calibration zones” map shown above to verify that the compass zone setting is correct for your geographical location. 2. Press and hold the compass display button for 3 seconds until the zone selection comes up (a number will be displayed in the mirror compass window). 3. Press the compass display button repeatedly until the correct zone setting for your location is displayed. 4. Releasing the button for 5 seconds will exit the zone setting mode. ! Compass calibration 1. If a “C” is displayed in the compass window, the compass needs to be calibrated. 2. Drive the vehicle in a circle at 5 mph (8 km/h) or less until the display reads a direction. 3. You can also calibrate the compass by driving your vehicle on your everyday routine. The compass will be calibrated once it has tracked a complete circle. 4. To recalibrate your compass, push and hold the compass display button for 9 seconds until a “C” appears in the compass window. 5. Calibrate the compass according to step 2 or step 3. !
