Safety
PreCrash system
Ho
w it works
The PreCrash system is an assistance system
that activ
es a series of measures to protect
the occupants of the vehicles in potentially
risky situations, but which cannot prevent a
collision.
It only works completely if no special driving
profile is selected and if there are no operat-
ing anomalies.
Basic features
Depending on the legal provisions of the
country and the features of the vehicle, in crit-
ical situations (e.g. in certain cases of emer-
gency braking or loss of control of the vehicle
by the driver) the following functions can be
activated separately or at the same time
when the vehicle is travelling faster than ap-
proximately 30 km/h (20 mph).
●
Reversible tensioning of front seat belts that
ar
e fastened.
●
Operation of the hazard warning lights.
●
Automatic closing of the windows until they
are just cracked open and, depending on the
equipment, of the sunroof.
●
In the event of overturning, depending on
the equipment, activation of the belt tension-
ers.
Depending on how critical the driving situa-
tion is, the belts are either tightened individu-
ally, or both belts at the same time.
In addition to Front Assist
In vehicles with Front Assist

within the limits of the system, information is
assessed on the risk of collision with the vehi-
cle in front. The functions of the PreCrash
system may also be activated if there is a
high likelihood of a rear-end collision, or dur-
ing the activation of Front Assist.
In addition to the Emergency Assist system
In vehicles with emergency assist, driver sta-
tus information is assessed within the limita-
tions of this system. The following PreCrash
systems may be activated if a lack of activity
is detected:
●
Reversible seat belt tensioning of the driv-
er's seat belt.
●
Automatic closing of the windows until they
are just cracked open and, depending on the
equipment, of the sunroof.
Activation of the PreCrash system
The PreCrash system can be partially deacti-
vated by deactivating the traction and / or
stability control, depending on the equip-
ment. When these vehicle safety controls are
switched on (by default, every time the igni-
tion is turned on), the system is fully activated.
Driving profile selection settings
In vehicles with driving profile selection,
PreCrash adapts to suit the special vehicle
configuration of the corresponding profile

Limited operation
The PreCrash system is not available or only
has limited availability in the following situa-
tions:
●
When the TCS and/or the ESC are discon-
nected.
●
When driving in reverse.
●
When the airbag control unit is not operat-
ing properly.
●
When there is a fault in the system itself, in
the ESC or in the Front Assist.
Problems and solutions
If the PreCrash is not working correctly, the
message System unavailable or System
with limited features is shown perma-
nently on the dashboard display. Have the
system checked by a SEAT workshop.
WARNING
The PreCrash system cannot overcome the
limits imposed by the l
aws of physics; it on-
ly works within the limits of the system.
Risks that compromise safety are never jus-
tified by the use of this system. The system
