136 Driving and parking
If you do not react to the visual or acoustic warn‐
ing, autonomous braking can be initiated in criti‐
cal 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 situation
detected as critical by Active Brake Assist, or
apply the brake during autonomous braking, sit‐
uation-dependent braking assistance occurs.
The brake pressure increases up to maximum
full-stop braking if necessary.
If the autonomous braking function or the situa‐
tion-dependent braking assistance is triggered,
additional preventive measures for occupant
protection (PRE-SAFE ® ) may also be initiated, if
the vehicle is equipped with these.
& WARNING Risk of an accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly
identify objects and complex traffic situa‐
tions.
Always pay careful attention to the traf‐
#
fic situation; do not rely on Active Brake
Assist alone. Active Brake Assist is only
an aid. The driver is responsible for
maintaining a sufficiently safe distance
to the vehicle in front, vehicle speed
and for braking in good time.
Be prepared to brake or swerve if nec‐
#
essary.

If the system is unavailable, the æ display
appears in the multifunction display.
Observe the system limitations of Active Brake
Assist.
The individual subfunctions are available in
the following speed ranges:
Distance warning function
The distance warning function issues a warning
at speeds:
From approximately 30 km/h, if over several
R
seconds the distance maintained to the vehi‐
cle travelling in front is insufficient for the
driven speed. The L distance warning
lamp then lights up in the instrument cluster.
From approximately 7 km/h, if your vehicle
R
is critically close to a vehicle or pedestrian.
An intermittent warning tone sounds and the
L distance warning lamp lights up in the
instrument cluster.
Brake immediately or take evasive action, provi‐
ded it is safe to do so and the traffic situation
allows this.
The distance warning function can aid you in the
following situations:
Vehicles travelling in front: up to approx‐
R
imately 250 km/h
Stationary vehicles: up to approximately
R
70 km/h
