According to a recent report from a source close to General Motors, the Chevrolet Silverado and the GMC Sierra pickup trucks will be offered with Trailer Side Blind Zone Alert from the middle of next year.
They call the new function ”Extended Side Blind Zone Alert”. It will come under the RPO Code “UKV”. The ESBZA will be available in the Sierra and Silverado in 2021 as a mid-year update, or in 2022, if the coronavirus causes a delay.
Side Blind Zone Alert, an active safety technology of General Motors, serves to help warn you of vehicles in your side blind zones and avoid lane change collisions.
This feature provides side-mirror visual alerts when a moving vehicle is revealed in a side blind zone. Hidden radar sensors it has detect vehicles in move, which are located behind your side mirror in the next lane over.
