Technical Background

See the chapter on “Active front assist” in the Owner's Manual.

Production Solution
Not applicable.
Service

This bulletin may apply to vehicles still within the new model launch repair authorization period!

- For vehicles still in the launch phase, the workshop must create a case with the Technical Assistance

Center (TAC) per the repair authorization. Reference this TSB number in the first line of the TAC case.

You can use the “Active front assist” test program to call up the intervention history and display it in ODIS-S. The
test program can be found under:

Test plan > Select own test... > Diagnostic capable system > 0013 - Adaptive cruise control — J428 > 0013 -

Technical Product Information > Active front assist

The test program asks you to enter the date of the intervention. The test program checks whether active front assist
interventions took place in the period between three days before and three days after the date entered. At the end,
the program provides a list of the interventions during this period.

In the table below, you will find an overview of the various interventions and their explanations:

assist”

Preliminary warning If a possible collision risk is detected, the driver is made aware of the danger by a visual
and acoustic warning.

Main warning If there is an immediate risk of a collision, an acute warning may be issued in the form of
a short brake jolt. The only way of avoiding the collision may be for the driver to take
evasive action or to brake sharply.

RAB Reaction time-increasing automatic braking (RAB):

Early initiation of partial braking increases the time until the impending collision and thus
gives the driver more time to react appropriately. The driver is also made aware of a
dangerous situation and the speed of impact is reduced in the event of a possible
collision.

DAB Deescalating automatic braking (DAB):

In situations where a collision can only be avoided by braking immediately, automatic
braking is performed. This helps to avoid accidents or reduces their severity.

AFB Automatic braking to a stop (AFB):

In critical situations at intersections, when driving away from a standstill and at low
speeds, the vehicle is automatically braked to a stop to prevent a collision with
oncoming vehicles in the adjacent lane or vehicles/cyclists crossing the vehicle's path.

FZB Driver-triggered controlled braking (FZB):

In critical situations, the braking force applied by the driver is increased so that a
collision is avoided, if possible. This sub-function assists drivers who do not brake

sufficiently in critical situations.
AWU Swerve support (AWU):
Swerve support is a corrective steering function which can assist the driver for a limited
time within the system limits when there is a risk of a frontal collision with stationary or
oncoming road users or road users moving in the same direction. To do this, the system
continuously determines the current collision risk. If the driver makes a clear steering
movement when there is an acute collision risk, the system checks whether it is possible
to avoid the collision by swerving in the direction specified by the driver's steering
movement. If there is sufficient space to swerve and thus to avoid a collision, the system
assists the driver in performing the evasive maneuver they initiated by providing steering
assistance; the system may also perform targeted braking of individual wheels. In
addition to this, partial braking to reduce the vehicle’s speed may also be performed
during the evasive maneuver. The driver can override the assistance provided by the
swerve support at any time.
