Activation of emergency tensioning
retractors, belt force limiters and air-
bagsIn the event of a collision, the
sensor in
the airbag control unit evaluates impor-
tant physical data, such as duration, di-
rection and rate of vehicle deceleration
or acceleration. Based on the evaluation
of this data and depending on the vehi-
cle’s rate of longitudinal deceleration in
a collision, in the first stage, the airbag
control unit pre-emptively triggers the
emergency tensioning retractors.

In this case, have the SRS system
checked and repaired immediately at a
qualified specialist workshop which has

on.) (

\4
in the event of a head-on or rear-end
collision, if there is a high rate of ve-
hicle acceleration or deceleration in
the initial stages of a collision
\4
in the event of a side impact, if the
vehicle suddenly decelerates or ac-
celerates in a lateral direction at the
initial stage of the impact and the ve-
hicle is equipped with thorax /
sidebags and / or windowbags.If the emergency tensioning retractors
are triggered, you will hear a bang that is
generally harmless to your hearing. A
small amount of powder may also be re-
leased. The

ESP
® remains active despite ASR having
been deactivated and carries out braking
interventions if this is necessary to im-
prove driving stability. Thev warning
lamp flashes.
If ASR is deactivated, there is an in-
creased risk that the brake system of your
vehicle could overheat and be damaged
when subjected to high loads for a long
period of time. A hot brake system also in-
creases the stopping distance.
For this reason, only deactivate ASR when
it is absolutely necessary.
