& WARNING Risk of accident if Lane
Change Assist unexpectedly stops func‐
tioning
If the system limitations for Lane Change
Assist have been reached, there is no guar‐
antee that the system will remain active.
Lane Change Assist cannot then assist you
by applying steering torque.
Always monitor the lane change and
#
keep your hands on the steering wheel.
Observe the traffic conditions and steer
and/or brake if necessary.

Active Brake Assist can help you to minimize the
risk of a collision with vehicles, cyclists or
pedestrians or to reduce the effects of such a
collision.
If Active Brake Assist has detected a risk of colli‐
sion, a warning tone sounds and the L dis‐
tance warning lamp lights up in the instrument
cluster.
If you do not react to the warning, autonomous
braking can be initiated in critical situations.
In especially critical situations, Active Brake
Assist can initiate autonomous braking directly.
In this case, the warning lamp and warning tone
occur simultaneously with the braking applica‐
tion.
If you apply the brake yourself in a critical situa‐
tion or apply the brake during autonomous brak‐
ing, situation-dependent braking assistance
occurs. The brake pressure increases up to max‐
imum full-stop braking if necessary.
