Air conditioning
The air is cooled and
dehumidified and Ñ
depending on the temperature setting Ñ
warmed again. Depending on the
weather, the windshield may fog over
briefly when the engine is started. You
can reduce condensation forming on
the windows by switching on the air
conditioning.
During air conditioning condensa-
tion forms, which then exits under
the vehicle. Traces of condensed water
of this kind are thus normal.<
Maximum cooling
You will get maximum
cooling capacity using this
program if the engine is running and
the outside temperature is above
approx. +41 7/+5 6.
The temperature display 9 jumps to
+60 7/+16 6, the system switches
over to the recirculated-air mode, and
the air streams out of the ventilation grill
with the maximum air supply. That is
why you need to keep these open if you
select this program.
Automatic recirculated-air
control AUC
If there are unpleasant
odors or pollutants in the
outside air, you can temporarily block
the air supply from the outside. The
system then recirculates the air
currently within the vehicle. Press the
button repeatedly to run through the
following control sequence
>Indicator lamps off: outside air supply
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air
currently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right-hand indicator lamp on: the
outside air supply into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
If you have a steering wheel with multi-
function buttons with the button for
recirculated-air mode, refer to page 23,
you can also use this button to switch
between Off and the recirculated-air
mode or AUC and the recirculated-air
mode.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.< Rear window defroster
When the rear window
defroster is activated,
the indicator lamp comes on. The
rear window defroster switches off
automatically.

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW Sports
Activity Vehicle center is familiar with
the factory specifications.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original container
and in a location which is inaccessible
to children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene-glycol. For this
reason, do not spill antifreeze with
corrosion inhibitor on hot engine parts.
It could ignite and cause serious
burns.<
Checking coolant level and
adding coolant Correct coolant level when the engine
is cold approx. +68 7/+20 6:
1. Start by turning the cap of the expan-
sion tank counterclockwise. Pause to
allow any accumulated pressure to
escape, then open
2. The coolant level is correct when the
end of the red float is aligned with
the upper edge of the filler opening,
refer to the arrow in the illustration,
or max. 0.8 in/2 cm higher, i. e. up to
the mark on the float, refer also to the
schematic diagram, next to the cap530us102
3. If necessary, add coolant. Slowly add
coolant until the correct level is
reached Ð do not overfill.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
