Notes on climate control

An interior ﬁlter in combination with the preﬁlter

in the engine compartment must always be used

so that the air conditioning system, pollution level

monitoring and the air ﬁltration work correctly.

Use ﬁlters recommended and approved by

Mercedes-Benz. Always have maintenance work

carried out at a qualiﬁed specialist workshop.

Notes on plug-in hybrids

Stop the charging process immediately

in case of unusual odours, smoke or

burn marks.

Leave the danger zone immediately.

Secure the danger zone at a suﬃcient

distance.

Depending on the system, it may be the case

that even though the high-voltage battery is

charged, electric mode has restricted or no

availability. Once the combustion engine has

been operated for long enough and ambient

conditions permit, electric mode will be avail-

able again without restriction.

Call the ﬁre service.

If the housing of the high-voltage battery has

been damaged, electrolyte and gases may
