SNOW CHAINS  
STRUCTURE  
Only use low profile chains, see  
“Snow chains”.  
Self-supporting chassis, three or five  
doors, high-resistance, multiple thick-  
ness structural elements for progres-  
sive energy absorption in impacts.  
Side bars in doors for side impact  
protection and stiffening the passen-

impacts.  
To ensure safety of the vehicle in  
movement, it must be fitted with tyres  
of specified size and of the same make  
and type on all wheels.

Front wheel toe-in measured from  
rim to rim: 0 1 mm.  
The values refer to the vehicle in run-
