Have the restraint system checked and
repaired immediately at a qualified spe-
cialist workshop.
Restraint system function during an
accident
The way the restraint system responds
depends on the severity of the impact
detected and the apparent type of accident:
Head-on collision
R
Rear impact
R
Side impact
R
The activation threshold for the restraint
system components is determined based on
the analysis of the sensor values measured
at various points in the vehicle. This proc-
ess is pre-emptive in nature. The trigger-
ing process of the restraint system compo-
nents should take place in good time at the
start of the collision.
Factors which can only be seen and meas-
ured after a collision has occurred do not
play a decisive role in the deployment of an
airbag, nor do they provide an indication of
airbag deployment.
The vehicle may be deformed significantly
without an airbag being deployed. This is
the case if only parts which are relatively
easily deformed are affected and the rate of
vehicle deceleration is not high. Con-
versely, an airbag may be deployed even
though the vehicle suffers only minor
deformation. If, for instance, very rigid
vehicle parts such as longitudinal body
members are hit, the rate of vehicle decel-
eration may be sufficient.
The restraint system components can be
activated or triggered independently of
each other:
Component
Belt tensioners
Driver's airbag,
front-passenger
front airbag and
kneebag
Sidebag

WARNING
After the airbag deploys, the airbag parts
are hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified
specialist workshop as soon as possible.
i
smart recommends that you have the
vehicle towed to a qualified specialist
workshop after an accident. Take this
into account, particularly if a seat belt
tensioner was triggered or an airbag was
deployed.
If the belt tensioners are triggered or an
airbag is deployed, you will hear a bang,
and a small amount of powder may also be
released:
The bang will not usually affect your
R
hearing.
In general, the powder released is not
R
hazardous to health but may cause short-
term breathing difficulties to persons
suffering from asthma or other pulmo-
nary conditions.
Provided it is safe to do so, leave the
vehicle immediately or open the window
in order to prevent breathing difficulties.
