be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heat- ing can be activated again. Switching air-recirculation mode
on/off
General notes You can deactivate the flow of fresh air if
unpleasant odours are enteringt he vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you activate air-recirculation mode, the win-
dows can mist up more quickly, in particular
at low temperatures. Only use air-recircula-
tion mode briefly to prevent the windows
misting up.
Activating/deactivating X
Turn the key to position 2in the ignition
lock (Y page 179).
X To activate: press thegbutton.
The indicator lamp above the gbutton
lights up.
i THERMATIC automatic climate control:
air-recirculation mode is activated auto-
matically at high outside temperatures.
THERMOTRONIC automatic climate con-
trol: air-recirculation mode is automatically
activated at high levels of pollution or at
high outside temperatures.
When air-recirculation mode is activated
automatically, the indicator lamp above the g button does not light up. Outside air is
added after about 30 minutes.
X To deactivate: press thegbutton.
The indicator lamp above the gbutton
goes out. i
Air-recirculation mode is deactivated
automatically:
