Some 2019 Transit vehicles equipped with power folding mirrors may exhibit the mirror housing vibrating while driving, moving freely, or not moving to the desired position. This may be due to the mirrors being inadvertently folded (manually) during transportation, going through a car wash, being bumped in a parking lot or found during pre-delivery inspection (PDI). Refer the operator to the Loose Mirror detail found in the Windows and Mirrors section of the Owner's Manual to reset the power-fold feature and correct the condition. Transit vehicles equipped with power folding mirrors contain a symbol representing the folding motion, on the mirror switch bezel.
