Troubleshooting
Points to remember
G
Risk of accident and injury
The operating safety of your vehicle could be compromised if service work is carried out improp-
erly. You could lose control of the vehicle and cause an accident. Safety systems may also not
be able to protect you or others as intended.
Always have maintenance work carried out at a qualified specialist workshop. The 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. Warning and indicator lamps in switches and buttons
