Risk of accident and injury
If maintenance work is carried out incorrectl y this can jeopardise the operating safety of your vehicle. You risk losing control of your vehicle
and thereby causing an accident. The safety systems may also no longer be able to protect you or others as they are designed to do.
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, all work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. Practical advice
