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

Notes on changing bulbs
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that all bulbs function correctly at all times. G
Risk of injury
Bulbs and lamps can be very hot. Yo u
should therefore allow them to cool down
before you change them. Otherwise, you
could be burned if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage them, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
H7 bulbs are pressurised and could explode
when you change them, particularly if they
are very hot. You should therefore wear eye
protection and gloves when you are chang-
ing them. G
Risk of injury
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or
even fatally injured if you touch the electri c
contacts on xenon bulbs. Therefore, neve r
remove the cover from xenon bulbs. Do not change xenon bulbs yourself, but
have them replaced at a qualified specialist
workshop which has the necessary special-
ist 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 work-
shop. Practical advice
