Resetting the Power Foldaway Mirrors You will need to reset the power foldaway mirrors if the following occurs: Outside Curb View Assist Mirrors If your vehicle has the optional memory package you may have this feature. The vehicle's mirrors are capable of performing the curb view assist mirror function. This feature will cause the passenger's and/or driver's mirror to tilt to a preselected position when the vehicle is in REVERSE (R). This feature may be useful in allowing you to view the curb when you are parallel parking. When the vehicle is shifted out of REVERSE (R) and a short delay has occurred, the passenger's and/or driver's mirror will return to its original position. To change the preselected tilt position, adjust the mirrors to the desired position while the vehicle is in REVERSE (R). When the vehicle is shifted out of REVERSE (R), this new position is saved in memory as the tilt position. You may be able to enable/disable this feature through the Driver Information Center. See Driver Information Center (DIC) on page 3-56. • They are accidentally manually folded/unfolded. • The mirrors will not stay in the unfolded position. • The mirrors shake and flutter at normal driving speeds. To reset the power foldaway mirrors, fold and unfold them at least three times using the mirror controls. This will reset them to their normal position. Outside Automatic Dimming Mirror If your vehicle is equipped with this feature, the driver's outside mirror will adjust for the glare of headlamps behind you. This feature is controlled by the on and off settings found on the electrochromic mirror. See Automatic Dimming Rearview Mirror with Compass and Temperature Display on page 2-46. 2-51
