System limitations, 262 driving aids – FORD 2014 Explorer v.3 User Manual
Page 263
If the system detects a degraded performance condition, a blocked
sensor warning or low visibility warning 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: 1)
when at least two objects are detected while driving, or 2) turn the
ignition key 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.
Reasons for messages being displayed
The radar surface is
dirty or obstructed
Clean the fascia area in front of the radar or
remove the obstruction.
The radar surface is
not dirty or obstructed
Drive normally in traffic for a few minutes to
allow the radar to detect passing vehicles so it
can clear the blocked state.
Heavy rainfall/snowfall
interferes with the
radar signals
No action required. The system automatically
resets to an unblocked state once the
rainfall/snowfall rate decreases or stops. Do not
use BLIS® and/or CTA in these conditions.
System Limitations
The BLIS® and CTA 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 CTA system:
• Adjacently parked vehicles or objects obstructing the sensors.
• Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
• Driving in reverse faster than 3 mph (5 km/h).
• Backing out of an angled parking spot.
