Troubleshooting
Points to remember
G
Risk of accident and injury
The operating safety of your vehicle may be affected if service work is carried out incorrectly.
You could lose control of your vehicle and cause an accident. In addition, the safety systems may
no longer be able to protect you or others as they are designed to do.
Always have service work performed 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. Warning and indicator lamps in switches, buttons and exterior mirrors

X Solutions The seat ventilation*
has switched itself off
prematurely. The on-board voltage is too low, because too many consumers are

X Switch off consumers that are not required, e. g. the reading
lamp or interior lighting. The seat heating has
switched itself off pre-
maturely. The on-board voltage is too low, because too many consumers are

X Switch off consumers that are not required, e. g. the reading
