WARNING
Repeatedly switching on the seat heating
can cause the seat cushion and backrest
pads to become very hot. The health of per-
sons with limited temperature sensitivity or
a limited ability to react to high tempera-
tures may be affected or they may even suf-
fer burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.

When the seat heating is switched on, the
seat surface can be damaged as a result of
objects being placed on the seats, for exam-
ple, seat cushions, child seats and protec-
tive covers not approved by Mercedes-Benz.

surface when the seat heating is switched
on.

Problems with the seat heating
Problem
Possible causes/consequences and MM Solutions
The seat heating has
switched off prema-
turely or cannot be
switched on. The vehi-
cle's electrical system
voltage is too low
because too many elec-
trical consumers are
switched on.
Switch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, switch on the seat heating
again.
