If your vehicle has this feature, the power mirror control is located on the driver's door.

Turn the control clockwise or counterclockwise to choose the passenger's or driver's side mirror. Then move the control in the desired direction

Adjust each mirror so a little of the side of the vehicle can be seen while sitting in a comfortable driving position.
