Using the radar sensors, the PRE-SAFE
®
Brake detects obstacles that are in your
driving path for a sufficient period of time for
the system to recognize it. If you approach a
vehicle and the PRE-SAFE
®
Brake has
established that the distance to the vehicle
ahead at your current speed is so close that
the PRE-SAFE
®
Brake will not be capable of
slowing the vehicle sufficiently, the system
will initially warn you visually and acoustically.
If you do not apply the brakes yourself or
maneuver around a sensed obstacle, the
vehicle will brake lightly automatically. The
PRE-SAFE
®
system (
Y
page 53) is activated
when the distance to the vehicle ahead at
your current speed is so close that the PRE-
SAFE
®
Brake will not be capable of slowing
the vehicle sufficiently.
When the danger of a collision still persists
and you do not brake or accelerate
significantly, the PRE-SAFE
®
Brake may
initiate full application of the brakes
automatically.
G
Warning!
The PRE-SAFE
®
Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by
R
dirty or covered sensors
R
snowfall or heavy rain
R
disturbance from other radar sources
R
strong radar reflection such as in parking
garages
The PRE-SAFE
®
Brake uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason the PRE-
SAFE
®
Brake will not react to persons,
animals, and approaching traffic or cross-
traffic.
The PRE-SAFE
®
Brake may not detect narrow
vehicles driving in front of you, such as
motorcycles and vehicles driving offset from
your vehicle center.
G
Warning!
Depending on the vehicle speed, the
PRE-SAFE
®
Brake brakes your vehicle with a
maximum of 13 ft/s
2
(4 m/s
2
) before a
possible hard stop. This corresponds to about
40% of the maximum deceleration ability of
your vehicle. The driver must apply the brakes
additionally in order to prevent a collision. The
self-acting hard stop will be initiated when the
imminent danger of a collision exists, e.g.
when an evasive driving maneuver cannot
avoid an accident.
