Operation
During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
R
duration
R
direction
R
intensity
Based on the evaluation of this data, the
restraint system control unit triggers the seat
belt tensioners in the event of a head-on or rear
collision.
A seat belt tensioner can be triggered only if:
R
the ignition is switched on
R
the components of the restraint system are
operational. You can find further information
under: "Restraint system warning lamp"
(
Y
page 31)
R
the seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The seat belt tensioners in the rear compart-
ment are triggered independently of the lock
status of the seat belts.
If the restraint system control unit detects a
high-severity accident, in certain head-on colli-
sions, additional components of the restraint
system are deployed independently of each
other:
R
driver's airbag
R
front-passenger front airbag
Depending on the person in the front-passenger
seat, the front-passenger front airbag is either
disabled or enabled. The front-passenger front
airbag can be deployed in an accident only if the
PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BAG OFF indicator lamp (
Y
page 32).
Your vehicle has a two-stage driver's airbag. In
the first deployment stage, the driver's airbag is
filled with enough propellant gas to reduce the
risk of injuries. The driver's airbag is fully
deployed if the second deployment stage is acti-
vated within a few milliseconds.
The activation threshold for the seat belt ten-
sioners and airbags is determined based on the
evaluation of the vehicle's rate of deceleration
or acceleration at various points in the vehicle.
This process is pre-emptive in nature. The trig-
gering/deployment process should take place
in good time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
R
the distribution of forces during the collision
R
the collision angle
R
the deformation characteristics of the vehicle
R
the characteristics of the object with which
the vehicle has collided
Factors that can be seen and measured only
after a collision has occurred do not play a deci-
sive role in the deployment of an airbag. Nor do
they provide an indication of airbag deployment.
The vehicle may be deformed significantly with-
out an airbag being deployed. This is the case if
only parts that are relatively easily deformed are
affected and the rate of deceleration is not high.
Conversely, an airbag may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact or if the vehicle overturns, the applicable
components of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
R
Front seat belt tensioners, if the system
determines that deployment can offer addi-
tional protection for the vehicle occupants in
this situation
R
Rear seat belt tensioners in certain situations
if the vehicle overturns
i
Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other.
How the airbag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:
R
frontal collision
R
side impact
R
overturn

Important safety notes
Accident statistics show that children secured
on the rear seats are safer than children secured
on the front-passenger seat. For this reason,
