142 Driving and parking
Function of EBD (electronic brake force dis‐
tribution)
EBD is characterized by the following:
Monitoring and regulating the brake pressure
R
on the rear wheels.
Improved driving stability when braking,
R
especially on bends.
Function of Active Brake Assist
Active Brake Assist consists of:
Distance warning function
R
Autonomous braking function
R
Situation-dependent braking assistance
R
Active Brake Assist can help you to minimize the
risk of a collision with vehicles 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.
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.
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
braking in good time.
Be prepared to brake or swerve if nec‐
#
essary.
Observe the system limitations of Active Brake
Assist.
