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 (Y 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 Pmust 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.
