Risk of accident and injury
The operating safety of the vehicle can be compromised if maintenance work is carried out
incorrectly. This could cause you to lose control of the vehicle and cause an accident. The safety
systems may also not be able to protect you or others as they are designed to do.
Always have maintenance work carried out at a qualified specialist workshop. The qualified spe-
cialist workshop must have 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. Display messages
