Risk of accident
If, in a critical driving situation, you do not
receive a visual and acoustic warning:
R
PRE-SAFE
®
Brake did not detect the risk of
a collision
R
PRE-SAFE
®
Brake is switched off
R
PRE-SAFE
®
Brake has failed
You must then brake to avoid a collision.
X
To activate: activate PRE-SAFE
®
Brake in
the on-board computer (

page 130).
The
Ä
symbol appears in the lower
multi-function display, as long as the HOLD
function is not activated (
Y
page 151).
On vehicles with parking guidance*, drive
range P must be engaged for the symbol to
be displayed.
The radar sensors are automatically deacti-
vated in the vicinity of radio telescope facili-
ties (
Y
page 362).
For PRE-SAFE
®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on and operational.
PRE-SAFE
®
Brake does not always detect
complex traffic situations properly. You can
terminate the braking action of PRE-SAFE
®
Brake in a non-critical driving situation at any
time if:
R
an acoustic and visual warning occurs
R
the vehicle brakes
To end this you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal.
The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R
you manoeuvre to avoid the obstacle.
R
you drive slower than approximately
15 km/h.
R
there is no longer an obstacle detected in
front of your vehicle.
R
there is no longer any danger of a collision.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked. Choose a qualified specialist work-
shop for this which has the necessary spe-
cialist knowledge and tools for the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose.
