ÿ Storage of the rear  
middle belt buckle  
– Seat belt pre-tensioners  
The back center belt buckle can be stored  
when not in use.  
The seat belt pre-tensioners for the driver and front  
passenger seats are designed to activate in the  
event of a severe frontal impact.  
The buckle must be stowed before the  
backrest is folded down. (See "Folding rear  
seat" on page 66 in this chapter.)  
If the airbag sensor detects a severe frontal  
impact, the front seat belts are quickly  
retracted by the seat belt retractors, so that  
the front seat passengers are safely restrained.  
The seat belt pre-tensioners are activated  
even if the front passenger seat is unoccupied.  
In an impact at certain speeds and at certain  
angles, the seat belt pre-tensioners and SRS  
airbags may not be activated together.
