Function of Active Emergency Stop Assist
Active Emergency Stop Assist uses touch sen‐
sors to monitor whether the driver holds the
steering wheel and initiates an emergency stop if
necessary.
If Active Steering Assist is deactivated, the
accelerator and brake pedal are monitored as
well as the steering wheel. A warning is issued
when the steering wheel is not being held or
when a pedal is not depressed, and the vehicle
is in danger of leaving the lane.
If the system detects that the driver has not
steered the vehicle for a considerable period of
time or has removed their hands from the steer‐
ing wheel, visual warning 1 is issued. If the
driver still does not steer the vehicle, or gives no
confirmation to the system, a warning tone
sounds in addition to the visual warning mes‐
sage.
Also observe the instructions on the contact
detection of Active Steering Assist
( page 248).
