Driving WARNING: Just prior to the system recognizing a blocked condition and alerting the driver, the number of missed objects will increase. To help avoid injuries, NEVER use the BLIS௡ as a replacement for using the side and rear view mirrors and looking over your shoulder before changing lanes. BLIS௡ is not a replacement for careful driving and only an assist. Once the blockage is removed, the system will require some driving time and detection of at least two vehicle objects prior to resetting or the driver can cycle the ignition key. If, however, blockage is still present after the key cycle, the system will sense again that it is blocked after driving in traffic. The following table lists possible causes and actions for this message being displayed: Clean the fascia area in front of the radar, either side, or remove obstruction. Drive normally in traffic for a few minutes to allow the radar to detect that it is no longer blocked. Note: The vehicle must be in D (Drive) and a few vehicles must pass so that the BLIS௡ can clear a blocked state. Heavy rainfall or heavy No action required by the driver. The snowfall is interfering with the system will automatically reset to an unblocked state once the radar signals rainfall/snowfall rate decreases or stops. Do not use BLIS௡ and/or CTA in heavy rainfall or heavy snowfall. Due to the nature of radar technology, it is possible to get a blockage warning and not be blocked. This is rare and known as a false blockage warning. A false blocked condition will either self clear or clear after a key cycle. Trailer tow false alerts When towing a trailer, the sensors may detect the trailer thus causing a false alert. It may be desirable to turn the BLIS௡ off if the false alerts become annoying. 246 The surface of the radar is dirty or obstructed in some way The surface of the radar is not dirty or obstructed 2012 MKX (mkx) Owners Guide, 1st Printing USA (fus)
