All other setting options for the automatic
climate control can be found at "Climate"
and in the menu on the Control Display,
refer to pages 90 and 91.
The current setting for air distribution is dis-
played on the Control Display.
A congenial climate
To use the automatic function, press the
AUTO button. Select an interior tempera-
ture you find pleasant.
The following section contains more
detailed information on the available set-
ting options.
The cooling function is only possible with
the engine running.
AUTO program
The AUTO program adjusts the
air distribution to the wind-
shield and side windows,
towards the upper body and footwell as
well as the air volume, while also using your
preselected temperature setting as the
basis for adjusting the interior climate to
adapt to external seasonal influences.
The cooling function comes on automati-
cally when you select the AUTO program.
At the same time, a condensation sensor
controls the program in such a way that
window condensation is prevented as far
as possible.
Temperature adjustment
The figures on the display pro-
vide a general indication of inte-
rior temperature. A pleasant
adjustment is 727/226.
When you start the vehicle, this system ensures that the selected tempera-
ture is achieved as quickly as possible. It
then maintains this temperature, regard-
less of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and front side win-
dows.
Adjusting air volume manually
You can adjust the air volume
by turning. You can reactivate
the automatic mode for the air
volume with the AUTO button.
Switching cooling function on and off
manually
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature set-
ting. Depending on the weather, the wind-
shield may fog over briefly when the engine
is started.
The cooling function comes on automati-
cally when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The system switches to the
recirculated-air mode and the
air flows at maximum air volume only from
the vent outlets for the upper body area.
For this reason you should ensure that
these vent outlets are open before select-
ing this program.
AUC Automatic recirculated-air
control
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air.
The system then recirculates the air cur-

A congenial climate
90 rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle continuously
>Right indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air
and recirculated-air modes
>Left indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is continuously blocked.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing
the air volume as required.
The recirculated-air mode should not be
used over a longer period of time, as the air
quality inside the vehicle deteriorates con-
tinuously.<
Residual heat mode
If you press this button with the
engine switched off, the system
uses the warmth stored in the
engine to heat the interior, for
instance, while the vehicle is
stationary at a school to pick up a child.
You can adjust the automatic climate con-
trol settings as of ignition key position 2.
Provided that the engine has warmed to its
normal operating temperature and the bat-
tery is charged, you can use this function
for up to 15 minutes after switching off the
ignition. The LED within the button lights up
to confirm compliance with both of these
conditions.
Switching off automatic climate
control
The air volume, the heater and
the cooling function are all
switched off. You can restart
the automatic climate control
by pressing any of its buttons
except the REST button.

Using tow fitting
The threaded tow fitting is stored in the tool
kit mounted on the inside of the luggage
compartment under the floor mat, refer to
page 178, and should always remain in the
vehicle. It can be screwed in at the front or
rear of the BMW.
To avoid damage to the tow fitting
and the vehicle, observe the follow-
ing: only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Only use the tow fitting to tow on the
roadway. Avoid heavy lateral loading of the
tow fitting, e.g. do not lift the vehicle by the
tow fitting.<

Being towed
Even if there is a failure in the electri-
cal system, make sure that the igni-
tion key is in position 1, as otherwise the
steering wheel could lock and it would be
impossible to steer the vehicle. There is no
power assist with the engine stopped. This then requires increased effort for braking
and steering. The active steering is deacti-
vated; when stopped and in the low speed
range greater steering wheel movements
are required.<
Switch on the hazard warning flashers
depending on the local regulations. If the
electrical system fails, mark the vehicle to
be towed, e.g. with a sign or warning trian-
gle in the rear window.
Vehicles with manual transmission
Gearshift lever in idle position
Vehicles with automatic
transmission
Selector lever in position N.
Do not exceed a towing speed of
45 mph/70 km/h and a towing dis-
tance of 90 miles/150 km, as otherwise the
automatic transmission may be dam-
aged.<
Vehicles with SMG Sequential
manual transmission
With the ignition switched on, engage
selector-lever position N, then switch off
the ignition.
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with all regulations on
towing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as oth-
erwise it will not be possible to control
vehicle response.<
The tow fittings used should be on the
same side on both vehicles. Should it prove
impossible to avoid mounting the tow bar
at an offset angle, please observe the fol-
lowing:
>Clearance and maneuvering capability
will be strictly limited in corners
