indicate that the PRE-SAFE
®
Brake will not be
capable 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
situation. Do not wait for the operation of the
warning signal to intercede with your own
braking, as that will result in potentially
dangerous emergency braking which will not
always result in an impact being avoided.
Tailgating increases the risk of an accident.
G
Warning!
The PRE-SAFE
®
Brake is a convenience
system designed to assist the driver during
vehicle operation. The responsibility for the
vehicle speed and the distance to the vehicle
ahead, including most importantly brake
operation to assure safe stopping distance,
always remains with the driver.
Always pay attention to traffic conditions
even while the PRE-SAFE
®
Brake is switched
on. Otherwise, you may not be able to
recognize dangerous situations until it is too
late and could cause an accident resulting in
personal or fatal injury to you or others.

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. If you approach an obstacle
and PRE-SAFE
®
Brake detects a risk of a
collision, the system will initially alert you
both visually and acoustically. If you do not
brake or steer, the vehicle will at first
automatically brake slightly. In the event of
an increased risk of a collision, PRE-SAFE
®
is
activated (Y page 51). If the risk of collision
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking.
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
