Automatic climate controlTips for pleasant drivingUse the automatic system; switch on
AUTO-button 7. Select an interior tem-
perature that is comfortable for you
– we recommend 707 (226) as a
comfortable setting. When the outside
temperature is above 407 (+ 56), you
can also use the air conditioning system
(12). This system dries the air and pre-
vents condensation on the windows
(e.g. if persons are wearing damp cloth-
ing). Set the outlets (2) so that the air
flows past you and is not directed
straight at you. Set the rotary dial be-
tween the air outlets (2) for the upper
body to a medium position, since air
that is somewhat cooler promotes driv-
ing without fatigue.
Detailed setting options are described
for you in the following section.
You can make the settings of your
vehicle in such a manner that,
when you unlock the car with your per-
sonalized remote control, your own per-
sonalized setting of the automatic cli-
mate control is initiated.<
Automatic air distribution
The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and in
addition adapts the temperature to
external influences (summer, winter) to
meet preferences you can specify. This
program maintains a comfortable in-car
climate regardless of the season. Select
an interior temperature that is comfort-
able for you – we recommend 707
(226). The temperature selected and
the word AUTO for the air supply
appear in display (10) (refer to the over-
view on page 88). Open the air outlets
for the upper body area. Switch on the
air conditioner in warm weather. The
maximum cooling capacity is achieved
when you set rotary dial (3) (refer to
page 92) to cold.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific distri-
bution patterns to suit your own
individual requirements. You
can direct air to flow onto the windows
, toward the upper body , and into
the footwell .
Temperature
The figures in the display provide
a general indication of interior
temperature. We recommend 707
(226) as a comfortable setting, whether
the air conditioner is operating or not.
When you start the vehicle, the system
ensures that the selected temperature is
reached as quickly as possible. It then
maintains this temperature, regardless
of the season.
Set rotary dial 3 (refer to "Draft-free
ventilation" on page 92) to a medium
setting, since air that is somewhat
cooler promotes driving without fatigue.
You can use this setting for mixing air to
make minor comfort modifications.
The full, uncontrolled heater out-
put is available starting at an inte-
rior temperature setting of 907 (326).
At a setting of 607 (166), the full cool-
ing output is available when the air con-
ditioner is activated.<

Automatic climate controlAutomatic recirculated-air control
(AUC)
*You can respond to unpleasant
external odors by temporarily
blocking outside air. The system then
recirculates the air already within the
vehicle. By repeated actuations of the
button, you can select one of three dif-
ferent operation modes.
>Indicator lamps off: Fresh air flows
into the vehicle
>Left-hand indicator lamp on – AUC
mode: The system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates the air already within the vehi-
cle. Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle.
>Right-hand indicator lamp on: The
flow of outside air into the vehicle is
permanently blocked. The system re-
circulates the air already within the
vehicle.
If the windows fog over in the re-
circulated air mode, switch this
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. Refer to
page 71.
Draft-free ventilation The air outlets for the upper body may
be adjusted to meet your personal re-
quirements:
Use the rotary dials (1) for an infinitely-
variable opening and closing of the
vents. You can use the levers (2) to
adjust the flow direction.
Set the outlets so that the air flows past
you and is not directed straight at you.
The rotary dial (3) allows you to mix the
air from the outlets for your upper body
by warming or cooling it as desired.460de040

Coolant
Do not add coolant to the cooling
system when the engine is hot,
since escaping coolant can cause
burns.
To avoid the possibility of damage later
on, never use anything other than fac-
tory-approved, nitrite- and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your authorized BMW center
is familiar with the official specifica-
tions.
Antifreeze and anticorrosion agents are
hazardous to health. Store antifreeze
and anticorrosion agents in their origi-
nal containers and inaccessible to chil-
dren. Extended-duty antifreeze with
corrosion inhibitor contains the flamma-
ble substance ethyleneglycol. Do not
spill antifreeze containing corrosion
inhibitor on hot engine components,
since it could catch fire and cause seri-
ous burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
Checking coolant levelCorrect coolant level when the engine
is cold (approx. 687 or 206):
Unscrew the cap from the expansion
tank.
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 the sche-
matic diagram next to the cap).460de053
Add coolant Wait until the engine cools before
removing the cap from the expansion
tank. The coolant gauge needle in the
instrument cluster must be located in
the blue field; otherwise, otherwise, you
could be scalded.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached – do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are re-
quired.
Replace the coolant every four years.
