WARNING

PRE-SAFE

®

Brake does not react:

R

to small people, e.g. children

R

to animals

R

to oncoming vehicles

to crossing traffic

R

when cornering

As a result, PRE-SAFE

®

Brake may neither

give warnings nor intervene in all critical sit-

uations. There is a risk of an accident.

Always pay careful attention to the traffic sit-

uation and be ready to brake.

In the event of snowfall or heavy rain, the rec-

ognition can be impaired.

Recognition by the radar sensor system is

also impaired in the event of:

R

there is dirt on the sensors or anything else

covering the sensors

R

there is interference by other radar sources

R

there are strong radar reflections, for

example in parking garages

R

a narrow vehicle traveling in front, e.g. a

motorbike

R

a vehicle traveling in front on a different line

relative to the center of your vehicle

Recognition by the camera system is also

impaired in the event of:

R

dirt on the camera or if the camera is cov-

ered

R

there is glare on the camera system, e.g.

from the sun being low in the sky

R

darkness

R

if:

-

pedestrians move quickly, e.g. into the

path of the vehicle

-

the camera system no longer recognizes

a pedestrian as a person due to special

clothing or other objects

-

a pedestrian is concealed by other

objects

-

the typical outline of a person is not dis-

tinguishable from the background

Following damage to the front end of the vehi-

cle, have the configuration and operation of

the radar sensors checked at a qualified spe-

cialist workshop. This also applies to colli-

sions at low speeds where there is no visible

damage to the front of the vehicle.

Following damage to the windshield, have the

configuration and operation of the camera

system checked at a qualified specialist work-

shop.
