79 Safety and Security
Driving safety systems
To maintain the proper distance to the ve-
hicle in front of you and thus prevent a 
rear-end collision, you must apply the 
brakes yourself.
Immediately brake the vehicle to avoid 
a collision.
Under no circumstances should the 
driver await the intermittent warning 
sound before braking. See the follow-
ing warning note.
The intermittent warning sound ceases 
and the distance warning lampl 
goes out when the necessary distance 
to the vehicle ahead is again 
established.PRE-SAFE
® Brake can react to stationary 
obstacles such as standing or parked vehi-
cles at road speeds of up to approximately 
40 mph (70 km/h).
Activating and deactivating: Activate 
or deactivate PRE-SAFE® Brake using 
the instrument cluster control system 
(
page 279).
After the function has been activated, 
indicator : appears on the 
left-hand side of the multifunction dis-
play.
Warning!G
An intermittent warning sounds and the dis-
tance warning lampl in the instrument 
cluster is illuminated if PRE-SAFE
® Brake 
calculates that the distance to the vehicle 
ahead and your vehicle’s current speed indi-
cate that PRE-SAFE
® Brake will not be capa-
ble of slowing the vehicle sufficiently to 
maintain the preset following distance, 
which creates a danger of a collision.
Immediately brake your vehicle to increase 
the distance between your vehicle and the 
vehicle driving in front of you. The warning 
sound is intended as a final caution that you 
have not interceded with your own braking 
inputs to avoid a potentially dangerous situ-
ation. Do not wait for the operation of the 
warning signal to intercede with your own 
braking, as that will result in potentially dan-
gerous emergency braking which will not al-
ways result in an impact being avoided.
Tailgating increases the risk of an accident.
Warning!G
If you do not receive visual or acoustic warn-
ing signals, PRE-SAFE® Brake has either not 
recognized the collision risk, has been deac-
tivated or is malfunctioning. Apply the 
brakes yourself to avoid a collision.
