FORD 2011 Edge v.1 - Manual (Page 279)

CTA detection limitations: Due to the nature of radar technology,
there may be certain instances where vehicles entering and exiting the
blind spot zones may not be detected. Below is a list of circumstances
that may cause non-detection:
• Debris build-up on the rear quarter panel fascias
• The rear quarter panel radar beams are obstructed or partially
obstructed by an adjacently parked vehicle or object.
• Approaching vehicles passing at speeds greater than 15 mph
(24 km/h)
• Severe weather conditions
• Driving in reverse faster than 3 mph (5 km/h)
• Backing out of an angled parking spot
CTA false alerts
Due to the nature of radar technology, there may be certain instances
when the BLIS
௡ will alert with no object present when backing up. This
is known as a false alert. Some level of false alerts are normal.
Circumstances that may cause a false alert when backing up are backing
out of a garage, backing in to a parking space, and objects very close to
the sensor. False alerts are temporary and self correct.
CTA and reverse sensing system (RSS) interaction
CTA works along with the reverse sensing system (RSS) (if equipped).
Become familiar with the warning tones of both systems.
BLIS
௡ and/or CTA on/off and disable operation
The BLIS
௡ and/or the CTA can be turned off via the message center. If
either the BLIS
௡ and/or the CTA is turned off, the systems will
automatically turn back on at the next ignition key cycle. When either
the BLIS
௡ and/or the CTA is turned off, the message center displays
BLIND SPOT SYS OFF and/or CTA SYSTEM OFF. When the BLIS
௡
and/or the CTA system is off, the driver will not receive alerts. Refer to
Message center in the Instrument Cluster chapter.
Note: If the system cannot be turned off, refer to MyKey™ in the Locks
and Security chapter for more information.
The BLIS
௡ and/or the CTA can be disabled permanently even after an
ignition key cycle. This must be done by your authorized dealer. Note:
Once either of the systems are disabled, enabling must also be performed
at the dealership. When disabled, the message center will display BLIND
SPOT DISABLED and/or CTA DISABLED.
