WARNING Risk of accident in poor road
and weather conditions
In poor road and weather conditions, the
trailer stabilisation cannot prevent lurching of
the vehicle/trailer combination. Trailers with
a high centre of gravity may tip over before
ESP
®
detects this.
#
Always adapt your driving style to suit
the current road and weather condi‐
tions.
ESP
®
trailer stabilisation counteracts critical driv‐
ing situations in good time and thereby provides
considerable assistance when driving with a
trailer. Trailer stabilisation is part of ESP
®
.
If the sensor system and evaluation logic detect
trailer swinging movements, ESP
®
trailer stabili‐
sation initially brakes individual vehicle wheels in
a targeted manner. It thus counteracts swinging
movements. If the swinging movements do not
stop, the vehicle is braked until the vehicle/
trailer combination is stabilised. If necessary, the
vehicle's engine output is limited.
If your vehicle with trailer (vehicle/trailer combi‐
nation) starts to swerve, you are able to stabilise
the vehicle/trailer combination only by braking.
ESP
®
trailer stabilisation helps you to stabilise
the vehicle/trailer combination in this situation.
ESP
®
trailer stabilisation is active above speeds
of 65 km/h.
If ESP
®
is deactivated because of a malfunction,
trailer stabilisation will not function.
Function of EBD (Electronic Brakeforce Distri‐
bution)
EBD has the following characteristics:
R
monitoring and controlling the braking force
on the rear wheels
R
improving driving stabilisation when braking,
especially on bends
Function of Active Brake Assist
Active Brake Assist consists of:
R
Distance warning function
R
Autonomous braking function
R
Situation-dependent braking assistance
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, you will be warned visually and acoustically.
If you do not react to the visual or acoustic warn‐
ing, autonomous braking can be initiated in criti‐
cal situations.
If there are pedestrians and cyclists crossing: in
especially critical situations, Active Brake Assist
can initiate autonomous braking directly. In this
case, the visual and acoustic warning occurs
simultaneously with the braking application.
If you apply the brake yourself in a critical situa‐
tion, or apply the brakes during autonomous
braking, situation-dependent braking assistance
occurs. The brake pressure increases up to maxi‐
mum full-stop braking if necessary. Situation-
dependent braking assistance only intervenes
when the brakes are applied firmly; otherwise, it
remains within the autonomous braking process.
&
WARNING Risk of accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly
identify objects and complex traffic situa‐
tions.
Due to the nature of the system, complex
driving conditions may also cause Brake
Assist to intervene or not intervene without
reason. In such cases, and in the event of
Active Brake Assist malfunctioning, the brake
system will continue to be available with full
brake boost and BAS.
#
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 of the vehicle is
responsible for keeping a sufficiently
safe distance to the vehicle in front, for
vehicle speed and for braking in good
time.
#
Be prepared to brake or swerve if nec‐
essary.
Also observe the system limitations of Active
Brake Assist.
