Each hide varies in its composition, strength, flexibility, etc.

Note:
•
Automotive upholstery is not cut from the exactly the same location and the exact same

•
This can vary from hide to hide.
•
The result is that there can be variations between leather upholstered components.
•
Body heat, perspiration and body weight cause fabric and leather to stretch, resulting in
“wrinkles”.
This visual change is perfectly normal and does
•
not affect its use, function or service life
•
and is not a defect.
 If a visual flaw that is clearly different from the "natural characteristics" described here is found, the
seat cover must be replaced:
