▌Function of brake application (Active Blind Spot
Assist)
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-correct-
ing brake application is carried out. This is
designed to help you avoid a collision.
The course-correcting brake application is availa-
ble in the speed range between approximately
20 mph (30 km/h) and 125 mph (200 km/h).
& WARNING Risk of accident despite brake
application of Active Blind Spot Assist
A course-correcting brake application cannot
always prevent a collision.
Always steer, brake or accelerate your-
#
self, especially if Active Blind Spot Assist
warns you or makes a course-correcting
brake application.
Always maintain a safe distance at the
#
sides.
If a course-correcting brake application occurs,
the red warning lamp flashes in the outside mirror
and a warning tone sounds. In addition, display
1 indicating the danger of a side collision
appears in the Instrument Display.
In rare cases, the system may make an inappro-
priate brake application. This brake application
may be interrupted at any time if you steer slightly
in the opposite direction or accelerate.
