Function of STEER CONTROL
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel in
the direction required for vehicle stabilisation.
This steering recommendation is given particu‐
larly in the following situations:
both right wheels or both left wheels are on a
R
wet or slippery road surface when you brake
the vehicle starts to skid
R
System limitations
STEER CONTROL may be impaired or may not
function in the following situations:
ESP
®
is deactivated
R
®
ESP
is malfunctioning
R
the steering is malfunctioning
R
If ESP
®
is malfunctioning, you will be assisted
further by the electric power steering.
Function of Active Brake Assist
Active Brake Assist consists of the following sub‐
functions:
Distance warning function
R
Autonomous braking function
R
Situation-dependent braking assistance
R
Vehicles with Driving Assistance Pack‐
R
age: Evasive Steering Assist
Active Brake Assist can help you to minimise the
risk of a collision with vehicles or pedestrians 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 · dis‐
tance warning lamp lights up in the instrument
cluster.
If you do not react to the warning, autonomous
braking can be initiated in critical 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 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 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
