Function of brake application (Active Blind

% The brake application function is only availa‐
ble for vehicles with a Driving Assistance
Package.
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-cor‐

designed to help you avoid a collision.
The course-correcting brake application is availa‐

20 mph (30 km/h) and 125 mph (200 km/h).
