driving dynamics situation.In such cases, the following systems are 
automatically activated:

If the front passenger seat or rear seats

Warning
G
The PRE-SAFE system is intended to reduce 
the effects of an accident on properly seat 
belted vehicle occupants. Despite having 
the PRE-SAFE systems in your car, the pos-
sibility of injuries occurring as a result of an 
accident cannot be totally eliminated. 
Therefore you should always drive carefully 
and adjust your driving to the prevailing 
road, weather, and traffic conditions.
iThe PRE-SAFE systems are activated at 
speeds exceeding 22 mph (35 km/h).
When the driving dynamic situation has 
passed without an accident occurring, 
the pre-tensioning on the seat belts is 
deactivated.
You can then adjust the seats and the 
sliding sunroof to their previous posi-
tion.
