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.

Once blockage is removed, the system will require some driving time and detection of at least two vehicle object prior to realizing it is unblocked, or the driver can cycle the ignition key. If blocked and the ignition key is cycled, the system resets to unblocked. 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 left or right side, or remove obstruction. Drive normally in traffic for a few minutes to allow the radar to detect that it is no longer blocked.
