culates the air currently within the vehicle.
During AUC operation, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>Indicator lamps off: outside air flows into the
vehicle.
>Left indicator lamp on, AUC mode: the sys-
tem recognizes pollutants in the outside air
and blocks the flow of air when necessary.
The system then recirculates the air cur-
rently 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 shut off contin-
uously. The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. The recirculated-air mode should not
be used over a sustained period of time, other-
wise the air quality inside the vehicle will deteri-
orate.<
Rear window defroster
When the rear window defroster is
activated, the indicator lamp
comes on. The rear window
defroster switches off automatically.
You can have your vehicle set so that the
rear window defroster switches on auto-
matically. It is then switched on at outside tem-
peratures of less than approx. +397/+46
within 5 minutes of the engine start.<
Ventilation
The air vents for the upper body area can be
adjusted:
1Serrated dials
Serrated dials for opening and closing the
vent outlets through an infinitely-variable
range.
2Levers
Selector levers for airflow direction.
3Serrated dial
Use this serrated dial to adjust the amount
of cool air that is added to the airflow
emerging from the vent outlets for the
upper body.
Ventilation for cooling
Adjust the vents to direct the flow of cool air in
your direction, for instance, if the interior has
become too warm.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
Microfilter/activated-charcoal filter*
The built-in microfilter removes dust and pollen
from the incoming air. The activated-charcoal
filter provides additional protection by filtering
gaseous pollutants from the outside air. This
combined filter is replaced when maintenance
is performed by your BMW Sports Activity Vehi-
cle Center. A substantial reduction in air supply
indicates that the filter should be replaced
before normal maintenance.

Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required professional technical training. If
you are not familiar with the regulations to be
observed, have work on your vehicle carried out
only by a BMW Sports Activity Vehicle Center
or a workshop that uses personnel trained in
accordance with BMW requirements. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards.<
Hood
Unlocking
Pull the lever located under the left side of the
instrument cluster.
Opening
Press the release handle and open the hood.
Closing
Let the hood fall from approx. 1 ft/30 cm so that

Observe the same precautions that apply
to all closing operations by ensuring that
the hood's travel range is clear and unob-
structed before allowing the hood to fall into
position.
If you see any signs that the hood is not com-
pletely closed while driving your vehicle, you
should stop at once and close it securely.<

Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine.<
Adding engine oil
Do not add oil until the oil level has dropped to
just above the lower marking on the dipstick,
refer to page90.
Add oil within the next 30 miles/50 km,
otherwise engine damage could result.<
Store oil, grease etc., well out of the reach
of children; always observe all warning
labels on the containers.<
Oil change
Have oil changed only at your BMW Sports
Activity Vehicle Center or at a workshop that
works according to BMW repair procedures
with correspondingly trained personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. Based on extensive testing, BMW
has approved only certain engine oils.
Use only approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil between oil
changes. Use only oils with the API SH specifi-
cation or higher.
Ask your BMW Sports Activity Vehicle
Center for details concerning the specific
BMW High Performance Synthetic Oil or syn-
thetic oils which have been approved. 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this information.
BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.<
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class depends
on the climate conditions in the area where you
typically drive your BMW.
Approved oils are in SAE classes 5W-40
and 5W-30.<
These oils may be used for driving in all ambient
temperatures.
Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW Sport Activ-
ity Vehicle Center for suitable additives.
Only use suitable additives, as otherwise
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-

Xenon lamps*
The service life of these bulbs is very long and
the probability of a failure is very low, provided
that they are not switched on and off an unusual
number of times. If one of these bulbs should
nevertheless fail, it is possible to continue driv-
ing with great caution using the fog lamps, pro-
vided traffic laws in your area do not prohibit
this.
