Driving The BLIS௡ will trigger the alert for vehicles that enter your blind zone from the rear or merge into the blind zone from the side. Vehicles that you pass, or a vehicle that enters the blind zone from the front, will trigger the alert only after the vehicle is present in the blind zone for three seconds. Note: For vehicles that pass through the blind zone quickly, typically less than two seconds, the BLIS௡ will not illuminate the alert. The BLIS௡ consists of two radar sensors each located rearward of the rear wheels hidden behind the bumper fascia. Do not place any type of bumper sticker in this area. Note: The BLIS௡ typically will not detect parked vehicles, humans, animals, or infrastructure (fences, guard rails, trees, etc.). The BLIS௡ does not function when the transmission is in R (Reverse) or P (Park). The BLIS௡ does not provide any additional warning when your turn signal is activated. BLIS௡ detection limitations: Due to the nature of radar technology, there may be certain instances where vehicles entering and exiting the blind spot zones may not be detected. Below is a list of circumstances that may cause non-detection: • Debris build-up on the rear quarter panel fascias • Certain maneuvering of vehicles entering and exiting the blind zone • Vehicles passing through the blind zone at very fast rates • Severe weather conditions • When several vehicles forming a convoy pass through the blind zone. BLIS௡ False Alerts Due to the nature of radar technology, there may be certain instances when the BLIS௡ will alert with no object present in the blind zone. This is known as a false alert. Some level of false alerts are normal. Circumstances that may cause a false alert are; guardrails, freeway concrete walls, cyclone fencing, sharp turns around a pole or building, or coming to a stop with a vehicle directly behind but very close. False alerts are temporary and self correct. 306 2012 Explorer (exp) Owners Guide, 2nd Printing USA (fus)
