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.
