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. The operating
safety of the vehicle can be affected if this work is carried out incorrectly. There is a risk of accident and injury. Indicator and warning lamps in switches and buttons
Problem Possible cause/consequence Suggested solutions
The seat heating* has switched
itself off prematurely or cannot
be switched on. There is insufficient voltage
because too many consumers are
switched on. X
Switch off consumers that are not required, e.g. reading lamps ,
interior lighting, etc .
The seat heating* will automatically switch back on as soon as
there is sufficient voltage again. The warning lamp on the sport
button of the ADVANCED AGILITY
package with sports mode* is lit. If you select comfortable mode
and the indicator lamp does not
go out, the ADVANCED AGILITY
package with sports mode* is
faulty. X
