160 Driving and parking
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 brake force boosting occurs.
The brake pressure increases up to maximum
full-stop braking if necessary.
If the autonomous braking function or the situa‐
tion-dependent brake force boosting 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 4 mph (7 km/h), if your
R
vehicle 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, if it is
safe to do so and the traffic situation allows this.
The distance warning function can aid you in
the following situations with an intermittent
warning tone and a warning lamp:
Vehicles traveling in
Up to approx.
front
155 mph (250 km/h)
Stationary vehicles
Up to approx. 50 mph
(80 km/h)
Crossing vehicles
No reaction
Moving pedestrians
Up to approx. 50 mph
(80 km/h)
Stationary pedes‐
No reaction
