Function of ESP
trailer stabilization
& WARNING Risk of accident in poor road
and weather conditions
In poor road and weather conditions, the
trailer stabilization cannot prevent lurching of
the vehicle/trailer combination. Trailers with
a high center 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 stabilization counteracts critical driv‐
ing situations in good time and thereby provides
considerable assistance when driving with a
trailer. Trailer stabilization is part of ESP
If the sensor system and evaluation logic detect
trailer swinging movements, ESP
zation 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 stabilized. 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 stabilize
the vehicle/trailer combination only by braking.
®
ESP
trailer stabilization helps you to stabilize
the vehicle/trailer combination in this situation.
®
ESP
trailer stabilization is active above speeds
of 40 mph (65 km/h).
If ESP
®
is deactivated because of a malfunction,
trailer stabilization will not function.
Function of EBD (electronic brake force distri‐
bution)
EBD has the following characteristics:
monitoring and controlling the braking force
R

Function of Active Brake Assist
Active Brake Assist consists of the following func‐
tions:
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 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‐
®
trailer stabili‐
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
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.
