WARNING Risk of injury or death due to  
incorrect seat position  
Persons under 5 ft (1.50 m) tall cannot wear  
the seat belt correctly without a suitable  
additional restraint system.  
If the seat belt is not worn correctly, it can‐  
not perform its intended protective function.  
In addition, an incorrectly fastened seat belt  
can also cause injuries, for example, in the  
event of an accident or when braking or  
changing direction suddenly.  
The seat belt does not offer the intended  
level of protection if you have not moved the  
seat backrest to an almost vertical position.  
When braking or in the event of an accident,  
you could slide underneath the seat belt and  
sustain abdominal or neck injuries, for exam‐  
ple.  
Seat belts may sustain non-visible damage in  
an accident, e.g. due to glass splinters.  
Modified or damaged seat belts could tear or  
fail in the event of an accident, for example.  
Modified Emergency Tensioning Devices may  
be deployed unintentionally or not function  
as intended.
