Driving Aids Reasons for messages being displayed The radar Clean the fascia area in surface is front of the radar or remove dirty or the obstruction. obstructed The radar surface is not dirty or obstructed Heavy rainfall/snowfall interferes with the radar signals Drive normally in traffic for a few minutes to allow the radar to detect passing vehicles so it can clear the blocked state. No action required. The system automatically resets to an unblocked state once the rainfall or snowfall rate decreases or stops. Do not use BLIS or cross traffic alert in these conditions. E142443 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. If the blockage is still present after the key cycle, the system senses again that it is blocked after driving in traffic. 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. The following are other situations that may limit the BLIS: • Certain maneuvering of vehicles entering and exiting the blind zone. • Vehicles passing through the blind zone at very fast rates. • When several vehicles forming a convoy pass through the blind zone. The following are other situations that may limit the cross traffic alert system: • Adjacently parked vehicles or objects obstructing the sensors. • Approaching vehicles passing at speeds greater than 15 mph (24 km/h). 191
