Proactive passenger protection (hereafter known as system) increases pas-
senger protection in the front seats in situations that could lead to vehicle im-
pact or overturning.
WARNING
The general information relating to the use of assistance systems must be
observed » page 135, in section Introduction.
Note
The system component service life is monitored electronically. Further infor-
mation » page 35,  Safety systems.
Function
Read and observe on page 160 first.
In critical driving situations (e.g. during emergency braking or a sudden change
in direction), the following steps can be taken separately or combined in order
to reduce the risk of serious injury.
▶
The front passenger's and driver's seatbelts, if worn, are automatically ten-
sioned closely over the body.
▶
The windows in the side doors (if open) are automatically closed up to a gap
of about 5 cm from the edge.
▶
The sliding/tilting roof is closed.
Once the critical driving situation has passed, the tension on the seatbelts will
be released again.
The system operates at two levels of protection.
The first level of protection
The system already intervenes in situations that may occur during dynamic
driving. As a result, this primarily helps to keep the driver and the passenger in
the correct seated position.

The first protection level can be deactivated in one of the following ways.
▶
The system deactivation in the Infotainment » Owner´s Manual Infotain-
ment, chapter CAR - vehicle settings.
▶
Deactivation of TCS » page 136.
▶
Selecting the driving mode Sport » page 157.
Provided that the driving mode Sport is not selected, the system is activated
over the two levels of protection after switching the ignition off and on again.
The second level of protection
The system intervenes only if the situation is evaluated as critical, such as in
panic braking at high speeds.
This level of protection cannot be deactivated.
Note

function for the front passenger seat is switched off.
