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 -CTA on/off and disable operation

The BLIS and/or the CTA can be turned off via the message center.
Turning the BLIS off does not turn off the CTA and vice-versa. If either
the BLIS or CTA is turned off, the systems will automatically turn back
on at the next ignition key cycle. When either the BLIS or CTA is
turned off, the message center displays BLIND SPOT SYS OFF and/or
CTA SYSTEM OFF. When the BLIS or CTA system is off, the driver will
not receive alerts. Refer to Message center in the Instrument Cluster
chapter.
The BLIS -CTA can be disabled permanently even after an ignition key
cycle. This must be done by your dealership service technician.
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.

BLIS -CTA fault operation

If the BLIS -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 left and/or right 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 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.
