BLIS ®

NOTE: On vehicles equipped with factory trailer tow, if a trailer is electrically connected to the vehicle, the BLIS ® is disabled.
NOTE: On vehicles without factory trailer tow, if a trailer is connected to the vehicle, the BLIS ® system may detect the trailer and cause a false alert.

The BLIS ® provides alerts to the driver when the vehicle is in a forward gear and the vehicle speed is greater than 10 km/h (6 mph).

The BLIS ® can trigger an alert for vehicles that enter the blind zone from the rear, front, or merge into the blind zone from the side. The exterior mirror BLIS ®/ CTA LED illuminates in the right and/or left exterior mirror when a target is present. For vehicles that pass through the blind zone quickly, typically less than 2 seconds, the BLIS ® may not trigger an alert.

If a turn signal is active while BLIS ® has detected a target in the blind zone, the BLIS ®/ CTA LED flash rapidly. When the turn signal is off, the BLIS ® target warnings is a constant LED illumination.

NOTE: There should be no bumper stickers or body filler material used on the rear side bumper cover in the vicinity of the SODL or SODR.
NOTE: The BLIS ® is not intended to detect parked vehicles, pedestrians, or objects such as fences, guard rails or trees.

Due to the nature of radar technology, false alerts may occur under certain circumstances. False alerts occur when the LED illuminates with no target present. False alerts up to 3% (3 out of 100 targets) is considered normal operation. False alerts are temporary and self-correcting. False alerts may be caused by sharp turns around a pole or building, jogging pedestrians or fast moving shopping carts.

Missed targets occur when a target is present and the LED does not illuminate. Missed targets up to 1% (1 out of 100 targets) is considered normal operation.

Circumstances that cause missed alerts are: 

The BLIS ® may not detect an adjacent target immediately when the vehicle accelerates from a standing start with another vehicle alongside.
