Automatic climate controlTips for pleasant drivingUse the automatic system, that is, press
AUTO button 4. Select an interior tem-
perature that is comfortable for you Ð
we recommend 727 (226). When the
outside temperature is above 417
(56), you can also use the air condi-
tioning system (12). This will dry the air
and prevent the window from fogging
(for example if people are wearing
damp clothes in the vehicle). Set the
outlets 2 so that the air flows past you
and is not directed straight at you. Set
the rotary dial between the outlets 2 for
the upper body to a central position.
This will provide cooler air, and help to
prevent fatigue during the journey.
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 indi-
vidualized remote control, your own
personalized setting for the automatic
climate control is initiated.<
Automatic air distribution
The AUTO program assumes
the adjustment of the air dis-
tribution and the air supply for you and
also adapts the temperature to external
influences (summer, winter) to meet
preferences you can specify. This pro-
gram maintains a comfortable in-car cli-
mate regardless of the season. Select
an interior temperature that is pleasant
for you Ð we recommend 727 (226).
The selected temperature and AUTO for
the air flow appear in the display 7. Re-
fer to the overview on page 98. Open
the ventilation outlets for the upper
body. Switch on the air conditioner in
warm weather. The maximum cooling
capacity is achieved when you set the
rotary dial 3 (refer to page 102) to cold.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
You can direct air to flow onto the win-
dows , toward the upper body ,
and into the footwell .
Temperature
You can make individual tem-
perature settings on the
driver's side or the front pas-
senger side. Your settings will be
shown in the display 9. The displayed
temperatures are reference values for
the interior temperature. We recom-
mend 727 (226) as a comfortable
setting, whether the air conditioner is
operating or not.When you start the ve-
hicle, the system ensures that the se-
lected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the sea-
son.
Set the rotary dial 3 (refer to "Draft-free
ventilation" on page 102) to a medium
position to provide somewhat cooler
air. This helps to promote driving with-
out fatigue. Make use of this means of
mixing air especially for making minor
adjustments for personal comfort.
You can set uncontrolled heater
output at up to 907 (326). Full
cooling output is available from the air
conditioner down to 607 (166).<

Automatic climate control
If the windows should fog over in
the recirculated air mode, switch
the recirculated air mode off and in-
crease the air supply as required.<
Rear window defroster
When the rear window de-
froster is activated, the indica-
tor lamp comes on. The rear window
defroster switches off automatically.
Residual heat mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine has
been switched off (while waiting at a
railroad crossing, for instance). In igni-
tion key position 1, you can alter the
settings of the automatic climate con-
trol. In ignition key position 0, the sys-
tem automatically directs heated air to
the windshield, side windows and foot-
wells.
This function may be activated
when the outside temperature is
below approx. 597 (156), the engine
is at operating temperature, and the
battery is adequately charged.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to select the opti-
mum airflow rates and directions for
your personal requirements:
Use rotary dial 1 to open and close the
airflow through an infinitely-variable
range. You can also use the levers 2 to
change the direction of the airflow.
Set the outlets so that the air flows past
you and does not flow directly on you.
Rotary dial 3 allows you to temper the
air flow from these outlets by adding
heat or cooling as desired:
Turn toward blue Ð colder
Turn toward red Ð warmer390de051
Rear passenger area ventilationRotary dial 1 opens the outlets in an in-
finitely-variable range. You can vary the
temperature of the air as it flows out us-
ing rotary dial 3 in the same manner as
for the front rotary dial.
You can change the direction of the air
flow with levers 2.390de354

Engine oil Coolant
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Recommendation: Have the oil
changed by your BMW center.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oil, grease, etc., out of
reach of children. Comply with all warn-
ing labels and information on lubricant
containers.<
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 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. You should always
store them in their original container
and in a location which is inaccessible
to children.
Extended-duty antifreeze with corrosion
inhibitor contains the flammable sub-
stance ethylene glycol. For this reason,
do not spill antifreeze with corrosion in-
hibitor on hot engine parts. It could
catch fire and cause serious 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. 687/206):
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 max.
0.8 in (2 cm) higher, for instance up
to the mark on the float (see also the
schematic diagram next to the cap).380de081
