Problems with the steering wheel heating
Problem
Possible causes/consequences and
M
MSolutions The steering wheel
heating has switched
itself off prematurely or
cannot be switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window heating or interior lighting.
Once the battery is sufficiently charged, the steering wheel
heating will switch back on automatically. EASY-ENTRY/EXIT feature

Climate contro lregulates the temperature
and the humidity in the vehicle interior and
filter sundesirable substances out of the air.
Climate contro lisonly operational when the
engin eisrunning. Optimum operation is only
achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 167).
i Ventilate the vehicle for
abrief period
during warm weather, e.g. using the con-
venience openin gfeature (Y page 111).
This will speed up the coolin gprocess and
the desired interior temperature will be
reached more quickly. i
The integrated filter filter
sout most par-
ticles of dust and soot and completely fil-
ter sout pollen. It also reduces gaseous pol-
lutant sand odours. Aclogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason ,you should always
observ ethe interval for replacin gthe filter,
which is specified in the Service Booklet. As this depends on environmental conditions,
e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed. The vehi-
cle is then ventilated for 30 minutes to dry the automatic climat econtrol. 156
