X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
If the driver and front passenger have their
seat belt fastened, PRE-SAFE
® Brake can also
brake the vehicle automatically at speeds
from approximately 20 mph (30 km/h) to
approximately 124 mph (200 km/h).
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE
® Brake. To stop the
braking action, you can either depress the
accelerator pedal further, activate kickdown
or release the brake pedal.
The braking action of PRE-SAFE
® Brake is
ended automatically if:
R
your speed drops below approximately
9 mph (15 km/h).
R you maneuver to avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R
there is no longer an obstacle detected in
front of your vehicle.

With the help of the radar sensor system,
PRE-SAFE
® Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds up to approximately 40 mph
(70 km/h), PRE-SAFE
® Brake can also react
to stationary obstacles, for example stopped
or parked vehicles.
If you approach an obstacle and PRE-SAFE
®
Brake detects a risk of collision, the system
will initially alert you both visually and
acoustically. If you do not brake or take
evasive action, the system will warn you by
automatically braking the vehicle gently. If
the risk of collision remains and you do not
brake, take evasive action or accelerate
significantly, the vehicle may perform
automatic emergency braking. Automatic
emergency braking is not performed until
immediately prior to an accident that can no
longer be avoided.
G WARNING
Even if PRE-SAFE ® Brake slows the vehicle
before an imminent rear-end collision, the
system cannot avert a collision without the
intervention of the driver. There is a risk of an
accident. Brake according to the situation or
take evasive action. Delayed intervention by
the driver can lead to an accident.
G WARNING
PRE-SAFE ® Brake cannot always detect
complex traffic situations properly.
