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 or 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. • Driving in reverse faster than 3 mph (5 km/h). Backing out of an angled parking spot. False Alerts Note: If your vehicle has a factory equipped tow bar and it is towing a trailer, the sensors detect the trailer and turn the Blind Spot Information and Cross Traffic Alert systems off to avoid false alerts. For non-factory equipped tow bars, you may want to switch the Blind Spot Information System off manually. There may be certain instances when there is a false alert by either the Blind Spot Information or the Cross Traffic Alert systems that illuminates the alert indicator with no vehicle in the coverage zone. Some amount of false alerts are normal; they are temporary and self-correct. System Errors If either system senses a problem with the left or right sensor, the Blind Spot Information System telltale illuminates and a message appears in the information display. See Information Messages (page 120). All other system faults only display with a message in the information display. Switching the Systems Off and On You can temporarily switch off one or both systems in the information display. See General Information (page 105). When you switch off the Blind Spot Information System, you do not receive alerts and the information display shows a system off message. The yellow alert indicator in the outside mirror also flashes twice. The system turns back on whenever you switch the ignition on. System Limitations The Blind Spot Information 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 Blind Spot Information System: • 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). 228 F-150 (), enUSA, First Printing
