BLIS
௡ and/or CTA fault operation
If the BLIS
௡ and/or CTA senses a fault on either the left or right sensor,
the BLIS
௡ alert indicator will go on and remain on and the message
center will display BLIND SPOT SYSTEM FAULT or CROSS TRAFFIC
SYSTEM FAULT. For faults that may cause the associated left or right
alert indicator not to illuminate, only the message center faults will
occur.
Blocked sensor
An extreme build-up of materials on
the quarter panel fascias such as
mud or snow can cause degraded
performance of the BLIS
௡. Also,
heavy rain can cause the same
effect. The BLIS
௡ can detect this
degraded performance and issue a
blocked warning to the driver via
the message center. If a condition is determined by the system, the
message center displays BLIND SPOT NOT AVAILABLE or CROSS
TRAFFIC NOT AVAILABLE warning and the appropriate left and/or right
exterior mirror alert indicator will illuminate. The message center
warning may be cleared by the driver but the exterior mirror alert
indicator will remain illuminated.
WARNING: Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLIS
௡ as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS
௡ is not a replacement for
careful driving and only an assist.
Once the blockage is removed, the system will require some driving time
and detection of at least two vehicle objects prior to resetting or the
driver can cycle the ignition key. If, however, blockage is still present
after the key cycle, the system will sense again that it is blocked after
driving in traffic.
