A system for mitigating contamination of a lens of an exterior vehicular camera includes a passive air flow device disposed at the vehicle and configured to passively direct air flow across an outer surface of a lens of the camera to establish a passive air stream curtain. An active air flow device is operable to actively propel air across the outer surface of the lens of the camera to establish an active air stream curtain. A control is operable to activate and deactivate the active air flow device. When the vehicle is driven at a speed of travel below a threshold level, the control activates the active air flow device to actively propel air across the outer surface of the lens of the camera. When the vehicle is in motion, the passive air stream curtain deflects polluting particles away from the outer surface of the lens of the camera.
