Blind Spot Information System (BLIS®) with Cross Traffic Alert

Your Lincoln may be equipped with innovative safety features to help alert you to potential traffic hazards. The Blind Spot Information System (BLIS®) will monitor your blind spot to help you change lanes safely, and the Cross Traffic Alert system will notify you of vehicles approaching your car while you are backing up. This video will explain how to use these features to help enhance the safety of your driving experience.


Blind Spot Information System (BLIS®)


Cross Traffic Alert


Using the systems

Using BLIS

BLIS will turn on when you start the engine and begin driving forward above 3 mph (5 km/h). It will remain on as long as the transmission is in drive (D) or neutral (N). If you shift into reverse (R), BLIS will deactivate and the system will enter Cross Traffic Alert mode. BLIS will reactivate once you shift back into drive and begin driving forward above 3 mph (5 km/h). BLIS does not function in reverse (R) or park (P). Using the turn signal will not cause BLIS to provide any additional warning.

Using Cross Traffic Alert

Cross Traffic Alert is designed to detect approaching vehicles from up to 45 feet (14 meters) away, though coverage decreases when the sensors are obstructed. Reversing slowly helps increase the effectiveness and coverage area of the system. For manual transmission vehicles, Cross Traffic Alert will be active only if the transmission is in reverse (R). If your vehicle is rolling backwards and the transmission is not in reverse (R), Cross Traffic Alert will not be active.

Cross Traffic Alert Coverage Zones

In this first Cross Traffic Alert example, the left sensor is only partially obstructed by a parked vehicle, and zone coverage is nearly maximized.

In this second Cross Traffic Alert example, parking at shallow angles limits zone coverage. The left sensor is mostly obstructed by a parked vehicle, which severely limits zone coverage on that side.

System Sensors

Sensor Obstructions and System Errors


  • Ensure that the system detects at least two vehicles while driving.
  • Cycle the ignition from on to off and then back on.


Warning message triggers

ConditionActionThe radar sensor surface is dirty or obstructed.Clean the fascia area in front of the radar sensor or remove the obstruction.The radar surface is not dirty or obstructed.Drive normally in traffic for a few minutes to allow the radar to detect passing vehicles and clear the blocked state.Heavy rainfall or snowfall is interfering with the sensor radar signals.No action required. The system will automatically reset to an unblocked state once rainfall or snowfall decreases or stops. Do not use BLIS or Cross Traffic Alert in these conditions.

System Limitations


  • Certain maneuvers of other vehicles as they enter and exit the blind zone.
  • Vehicles passing through the blind zone at very fast rates.
  • Several vehicles forming a convoy and passing through the blind zone.

Other situations that may limit the Cross Traffic Alert system include:

  • Adjacently parked vehicles or objects obstructing the sensors.
  • Approaching vehicles passing at speeds greater than 15 mph (24 km/h).
  • Driving in reverse faster than 3 mph (5 km/h).
  • Backing out of an angled parking spot.
