The warning prompts the driver himself/herself

to react. During a warning, the maximum brak‐

ing force is used. Premise for the brake boos‐

ter is sufficiently quick and hard stepping on

the brake pedal. The system can assist with

automatic braking intervention if there is risk of

a collision. The intervention can bring the vehi‐

cle to a complete stop.

The braking intervention is executed only if

DSC Dynamic Stability Control is switched on

and Dynamic Traction Control DTC is acti‐

vated.

Above approx. 130 mph/210 km/h the braking

intervention occurs as a brief braking pressure.

No automatic delay occurs.

The braking intervention can be interrupted by

stepping on the accelerator pedal or by ac‐

tively moving the steering wheel.

System limits

Detection range

The system's detection potential is limited.

Thus a warning might not be issued or be is‐

sued late.

E. g. the following situations may not be de‐

tected:

▷ Slow moving vehicles when you approach

them at high speed.

▷ Vehicles that suddenly swerve in front of

you, or sharply decelerating vehicles.

▷ Vehicles with an unusual rear appearance.

▷ Two-wheeled vehicles ahead of you.

▷ Pedestrians.

▷ Stationary objects.

Functional limitations

The system may not be fully functional in the

following situations:

▷ In heavy fog, rain, sprayed water or snow‐

fall.

▷ In tight curves.

▷ If the driving stability control systems are

limited or deactivated, e.g., DSC OFF.

▷ If the radar sensor is dirty or obscured.

Warning sensitivity

The more sensitive the warning settings are,

e.g. the warning time, the more warnings are

displayed. However, there may also be an ex‐

cess of false warnings.

Pedestrian warning with city

braking function

The concept

The ystem can help prevent accidents with pe‐

destrians.

The system issues a warning in the city driving

speed area if there is imminent danger of a col‐

lision with pedestrians and includes a braking

function.

The camera in the area of the rearview mirror

controls the system.

General information

In daylight the system warns of possible colli‐

sions with pedestrians at speeds from about

6 mph/10 km/h to about 35 mph/60 km/h

shortly before a collision the system supports

you with a braking intervention.

Under those circumstances it reacts to people

who are within the detection range of the sys‐

tem.
