Risk of accident and injury
Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out
the work required.
Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.
In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. There is a risk of an acci-
dent and injury if this work is carried out incorrectly.
