Points to remember
G
Risk of accident and injury
The operating safety of your vehicle could be compromised if service work is carried out improperly. You could lose control of the vehicle,
thereby causing 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 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 and buttons
Problem Possible cause/consequence Suggested solutions
One or all of the indicator lamps
in the seat heating* button are
flashing. The seat heating* has
switched itself off automatically. The on-board voltage is too low,
because too many consumers are
switched on. X
Switch off consumers that are not required, e. g. reading lamp or
interior lighting.
Once the battery is sufficiently charged, the seat ventilation* will
switch back on automatically. The indicator lamp in the
2
button on the air-conditioning */
Ther motronic* control panel
lights up. The cooling system can-
not be switched on. Cooling has been deactivated
due to a malfunction. X
Visit a qualified specialist workshop. Practical advice
