BLIS* – Cross Traffic Alert (CTA)
On vehicles equipped with the optional Park assist system, Cross Traffic Alert (CTA) can be deactivated/reactivated by pressing the Park assist button on the center console. The BLIS indicator lights on the front doors will flash when CTA is reactivated by pressing the button.
Warning
- BLIS and CTA are information systems, NOT warning or safety systems and do not function in all situations.
- BLIS and CTA do not eliminate the need for you to visually confirm the conditions around you, and the need for you to turn your head and shoulders to make sure that you can safely change lanes or back up.
- As the driver, you have full responsibility for changing lanes/backing up in a safe manner.
When does CTA function
CTA supplements BLIS by warning the driver of crossing traffic behind your vehicle, for example, when backing out of a parking space.
It is primarily designed to detect another vehicle but in certain cases may also detect pedestrians or smaller objects such as bicycles.
CTA is only activated when the vehicle is backing up and is activated automatically when the gear selector is put in reverse.
- An audible signal indicates that CTA has detected something that is approaching from the side. The signal will come from either the left or right audio system speakers, depending on which the side of your vehicle the approaching vehicle/object has been detected.
- CTA also provides a warning by illuminating the BLIS indicator lights.
- An icon will also illuminate in the Park assist graphic on the center console display.
Limitations
CTA has limitations in certain situations, for example, the CTA sensors cannot "see" through other parked vehicles or obstructions.
The following are several examples where CTA's "field of vision" may initially be limited and approaching vehicles cannot be detected until they are too close:
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a parking space, CTA's "field of vision" expands.
Examples of other limitations include:
- Dirt, ice or snow obstructing the sensors may reduce the system's function or make it impossible to detect other vehicles or objects.
- Do not attach tape, decals, etc., on the surface of the sensors (see the illustration in the following "Maintenance" section).
- BLIS and CTA are deactivated if a trailer's wiring is connected to the vehicle's electrical system.
