254 Driving and parking
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nise dangers ( page 229).
/
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
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.
1
Always pay careful attention to the traf‐
#
fic situation; do not rely on Active Brake
Assist alone.
Be prepared to brake or swerve if nec‐
#
essary.
Also observe the system limits of Active Brake
Assist.
The individual subfunctions are available in
various speed ranges:
The distance warning function can issue a warn‐
ing 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 insufficient 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, cyclist 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.
