ARNING Risk of accident despite Eva-
sive Steering Assist
Evasive Steering Assist cannot always recog-
nize objects or complex tra c situations
clearly.
Moreover, the steering support provided by
Evasive Steering Assist is not su cient to
avoid a collision.
Always pay careful attention to the tra c
#
situation; do not rely on Evasive Steering
Assist alone.
Be prepared to brake or swerve if neces-
#
sary.
End the support by actively steering in
#
non-critical situations.
h Driving iving Drive at an appropriate speed if there
#
are pedestrians close to the path of your
vehicle.
