232 Driving and parking
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.
If autonomous braking or situation-dependent
braking assistance has occurred, display
appears in the multifunction display and then
automatically goes out after a short time.
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.
& 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.
In such cases, Active Brake Assist might:
Give a warning or brake without reason
R
Not give a warning or not brake
R
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 suitable distance to the
vehicle in front, vehicle speed and for
1
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.
Also observe the system limits of Active Brake
Assist.
The individual subfunctions are available in
the following speed ranges:
The distance warning function issues a warning
in the following situations:
From approximately 30 km/h, if over several
R
seconds the distance maintained to the vehi‐
cle travelling in front is too small for the
driven speed, the L distance warning
lamp lights up in the instrument cluster.
From approximately 7 km/h, if your vehicle
R
is critically close to a vehicle or pedestrian,
you will hear an intermittent warning tone
and the L distance 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 ten‐
sioning of the seat belt.
Brake immediately or take evasive action, provi‐
ded it is safe to do so and the traffic situation
allows this.
