BLIS ®
The BLIS ® provides alerts to the driver when the vehicle is in a forward gear and the vehicle speeds 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 flashes rapidly. When the turn signal is off, the BLIS ® target warnings are a constant LED illumination.
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:
- Debris build-up or damage to the rear lamp assemblies
- Certain maneuvering of the vehicles entering and exiting the blind zone
- Vehicles passing through the blind zone at high rates of speed
- When several vehicles forming a convoy pass through the blind zone
The BLIS ® may not detect an adjacent target immediately when the vehicle accelerates from a standing start with another vehicle alongside.
