This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired immediately at a qualified spe-
cialist workshop. After an accident, switch
off the ignition immediately and remove
the key from the ignition lock.
Restraint system response during an
accident
How the restraint system works depends on
the severity of the impact detected and the
apparent type of accident:
head-on collision
R
rear collision
R
side impact
R
1
overturn
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 process is
pre-emptive in nature. The triggering proc-
ess of the restraint system components
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. Conversely, an air-
bag may be deployed even though the vehicle
suffers only minor deformation. If, for
instance, very rigid car parts such as longi-
tudinal body members are hit, the rate of
vehicle deceleration may be sufficient.
1 Only for certain countries.
The restraint system components can be
activated or triggered independently of each
other:
Components
Belt tensioners
Driver's airbag,
front passenger
front airbag and
knee airbag
Sidebag
Windowbag

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 belt tensioner
was triggered or an airbag was deployed.
If the belt tensioners are triggered or an air-
bag is deployed, you will hear a bang, and a
small amount of powder may also be
released:
the bang will not usually affect your hear-
R
ing.
in general, the powder released is not haz-
R
ardous to health but may cause short-term
breathing difficulties to persons suffering
from asthma or other pulmonary condi-
tions.
Provided it is safe to do so, leave the vehi-
cle immediately or open the window in
order to prevent breathing difficulties.
