Driving Aids Note: It is possible to get a blockage warning with no blockage present; this is rare and known as a false blockage warning. A false blocked condition either self-corrects or clears after a key cycle. If the blockage is still present after the key cycle, the system senses again that it is blocked after driving in traffic. Reasons for messages being displayed The radar Clean the fascia area in surface is front of the radar or dirty or remove the obstruction. obstructed The radar surface is not dirty or obstructed E142443 Drive normally in traffic for a few minutes to allow the radar to detect passing vehicles so it can clear the blocked state. The system uses radar sensors which are located behind the bumper fascia on each side of your vehicle. Do not allow these areas to become obstructed by mud, snow or bumper stickers, as this can cause degraded system performance. If the system detects a degraded performance condition, a message warning of a blocked sensor or a message warning of low visibility will appear in the information display and the alert indicator illuminates in the appropriate mirror(s). The information display warning can be cleared but the alert indicator remains illuminated. When the blockage is removed, the system can be reset in two ways: • when at least two objects are detected while driving, or • turn the ignition from on to off, then back on. Heavy No action required. The rainfall/ system automatically snowfall resets to an unblocked interferes state once the rainfall or with the snowfall rate decreases radar or stops. Do not use BLIS signals or cross traffic alert in these conditions. System Limitations The BLIS and cross traffic alert systems do have their limitations; situations such as severe weather conditions or debris build-up on the sensor area may limit vehicle detection. 214 MKZ (CC9)
