DANG ER Risk of death due tothe
re stra int sy stem malfunctioning
Components in there stra int sy stem may be
activated unintentionally or not deploy as
intended in an accident. In theeve nt of an
accident, the high-voltage on-board electrical
sy stem may not be deactivated as intended. Yo
u may recei vean electric shock if you
to uch the damaged components of the high-
vo ltage on-board elect rical sy stem. #
Have there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop. #
After an accident, switch off the ignition
immediatel y. Fu
nction of there stra int sy stem in an acci‐
dent How
there stra int sy stem works depends on the
se verity of the impact de tected and the apparent
type of acciden t:
R Frontal impact
R Rear impact
R Side impact
R Rollover
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on
th eev aluation of the sensor values measured at
va rious points in theve hicle. This process is pre- em
ptive in nature. The triggering/deployment of
th e components of there stra int sy stem must
ta ke place in good time at thest art of the colli‐
sion.
Fa ctors whi chcan only be seen and measu red
af te r a collision has occur red cann otplay a deci‐
sive role in airbag deployment. Nor do they pro‐
vide an indication of airbag deployment.
The vehicle may be deformed significantly with‐
out an airbag being deplo yed. This is the case if
only parts which are relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an airbag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts
such as longitudinal members are hit, this may
re sult in suf ficiently high le vels of vehicle decel‐
eration.
Depending on the de tected deployment situa‐
tion, the components of there stra int sy stem can
be activated or deplo yed independently of each

in an accident if thePA SSENGER AIR BAG OFF
indicator lamp is off. If the front passenger seat
is occupied, make sure, bo thbefore and during
th e journe y,that thest atus of the front

WARNING Risk of bu rns from hot airbag
components
The airbag parts are hot af ter an airbag has
