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
The built-in microfilter removes dust and pollen
from the incoming outside air. It is replaced
when maintenance is performed by your BMW
Sports Activity Vehicle Center. A substantial
reduction in air supply indicates that the filter
should be replaced before normal maintenance.

A congenial climate

A congenial climate
For almost all conditions, the AUTO pro-
gram 12 offers the optimal air distribution and
air volume. Select an interior temperature you
find pleasant.
The following section contains more detailed
information on the available setting options.
Your vehicle has been designed to auto-
matically select your personal climate-
control settings whenever you unlock the doors
using your individually programmed remote
control.<
Automatic air distribution and supply
The AUTO program adjusts the
airflow and distribution patterns for
you while also using your prese-
lected temperature setting as the basis for
adjusting the interior climate to adapt to exter-
nal influences: summer, winter.
The cooling is switched on automatically with
the AUTO program.
Individual air distribution
You can cancel the AUTO program
by selecting specific air distribu-
tion patterns for your personal
comfort, the automatic air supply
remains in operation. You can
direct air to flow onto the win-
dows , toward the upper body , and into
the footwell . You can reactivate the auto-
matic air distribution mode by selecting the
AUTO button.
Adjusting temperature
The figures in the display provide a
general indication of interior tem-
perature. When you start the vehi-
cle, the AUTO program ensures
that the selected temperature is
achieved as quickly as possible. It
then maintains this temperature, regardless of
the season.
Air supply/blower
You can vary the air supply by
pressing the upper or lower button.
This switches off the automatic
program for the air supply, and the
word AUTO goes out in the dis-
play. The automatic mode for air
distribution remains in operation as before. You
can reactivate the automatic air supply mode by
selecting the AUTO button.
If you press the lower button when at the lowest
blower speed, all displays go out: the blower,
heating and air conditioner are switched off.
The outside air supply is shut off. You can
restart the automatic climate control by press-
ing any of its buttons.
Defrosting windows and removing
condensation
This program quickly removes ice
and condensation from the wind-
shield and door windows.
Air conditioner
When the air conditioning is on,
the air is cooled, dehumidified,
and then reheated depending on
the temperature setting. Depending on the
weather, the windshield may fog over briefly
when the engine is started. The air conditioner
reduces the formation of condensation on the
windows.
The air conditioner can only operate when the
engine is running and is automatically switched
on with the AUTO program.
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.<
Outside air/AUC Automatic
recirculated-air control/recirculated-
air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by suspending
the supply of outside air. The system then recir-

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.

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-
