out of your automatic climate control.
R Activate climate control using the 0058and
005A buttons. The indicator lamps in the
0058 and005A button slight up.
R Set the temperature to 72 ‡(22 †).
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in atunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the MONO function if you want to
adopt the temperature and air distribution
settings from the driver's side for all cli-
mate control zones. The indicator lamp in
the 005B button lights up. Operating the climate control sys-

cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.

General notes In automatic mode, the set temperature is
controlled automatically. The system auto-
matically regulates the temperature of the
dispensed air, the airflow and the air distri-
bution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,

Problem
Possible causes/consequences and

0050Solutions The rear window
defroster has deacti-
vated prematurely or
cannot be activated. The on-board voltage is too low because too many electrical con-
sumers are switched on.

lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can deactivate the flow of fresh air if
unpleasant odors are enteringt
he vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.

WARNING
The brake fluidc onstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake fluidist oo low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is arisk of an accident. You shoul
dhave the brake fluidr enewed at
the specified intervals.
When handling brake fluid, observe the
important safety notes on service products
(Y page 281).
The brake fluidc hange intervals can be found
