Function of PRE-SAFE
®
PLUS (anticipatory
occupant protection plus)
PRE-SAFE
®
PLUS can detect certain impacts,
particularly an imminent rear impact, and take
pre-emptive measures to protect the vehicle
occupants. These measures cannot necessarily
prevent an imminent impact.
PRE-SAFE
®
PLUS can implement the following
measures independently of each other:
R
Tightening the seat belts on the driver's seat
and front passenger seat.
R
Increasing brake pressure when the vehicle
is stationary. This brake application is can‐
celed automatically when the vehicle pulls
away.
If an accident did not occur, the pre-emptive
measures that were taken are reversed.
System limits
The system will not initiate any action in the fol‐
lowing situations:
R
when backing up
The system will not initiate any braking applica‐
tion in the following situations:
R
whilst driving
or
R
when entering or exiting a parking space
while using Active Parking Assist
Safely transporting children in the vehicle
Always observe when children are traveling
in the vehicle
%
Also strictly observe the safety notes for the
specific situation. In this way you can recog‐
nize potential risks and avoid dangers if chil‐
dren are traveling in the vehicle
(/ page 49).
Be diligent
Bear in mind that neglecting to secure a child in
the child restraint system may have serious con‐
sequences. Always be diligent in securing a child
carefully before every journey.
To improve protection for children younger than
12 years old or under 5 ft (1.50 m) in height,
Mercedes-Benz recommends you observe the
following information:
R
Always secure the child in a child restraint
system suitable for this Mercedes-Benz vehi‐
cle.
R
The child restraint system must be appropri‐
ate to the age, weight and size of the child.
R
The vehicle seat must be suitable for instal‐
ling a child restraint system.
Accident statistics show that children secured
on the rear seats are generally safer than chil‐
dren secured on the front seats. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat.
