Up to a speed of approximately 70 km/h,
Adaptive Brake Assist reacts to stationary
obstacles.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
are activated simultaneously (
vehicles with the Driving Assistance package,
preventive passenger protection measures
®
(PRE-SAFE PLUS) are triggered (
Keep the brake pedal depressed until the

emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
you release the brake pedal
R
there is no longer any danger of a collision
R
no obstacle is detected in front of your
R
vehicle
Adaptive Brake Assist is then deactivated.
Important safety notes

Observe the "Important safety notes" sec-
tion for driving safety systems (
G WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
intervene unnecessarily
R
not intervene
R
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
WARNING
G
Adaptive Brake Assist does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
R
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.

If Adaptive Brake Assist is not available due to
a malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.
Adaptive brake lights
The adaptive brake lights warn following traf-
fic in an emergency braking situation:
by flashing brake lamps
R
by activating the hazard warning lamps
R
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS

or BAS PLUS, the brake lamps flash rapidly. In
this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning button (
