200 Driving and parking
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, display 1 appears in the multifunc‐
tion display. 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 message.
If the driver still does not respond to the warn‐
ing, the Beginning emergency stop
appears in the multifunction display. If the driver
still does not respond, Active Distance Assist
DISTRONIC reduces the speed. The vehicle is
decelerated in stages to a standstill.
Depending on the country, at speeds below
60 km/h the hazard warning lights switch on
automatically.
When the vehicle is stationary, the following
actions are carried out:
The vehicle is secured with the electric park‐
R
ing brake.
Active Distance Assist DISTRONIC is ended
R
The vehicle is unlocked.

If possible, an emergency call is placed to
R
the Mercedes-Benz emergency call centre
The driver can cancel the deceleration at any
time by performing one of the following actions:
Steering
R
Braking or accelerating

Function of Active Brake Assist
Active Brake Assist consists of the following
functions:
Distance warning function
R
Autonomous braking function
R
Situation-dependent braking assistance
R
Vehicles with Driving Assistance Pack‐
R
age: Evasive Steering Assist and cornering
function
Active Brake Assist can help you to minimise 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.
®
Vehicles with PRE-SAFE : depending on the
country, an additional haptic warning occurs in
the form of slight, repeated tensioning of the
seat belt.
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.
